So, what's new? Not a huge amount. Did a track day at Snetterton in December which was fun, but the alternator overheated in my first afternoon session. It was so hot I actually burned my finger when I touched it! It was functional after cooling down, but it's now noisy, so I think that may have killed the bearings. I've got a new belt to try first on the off chance, but I think it might need an alternator replacement soon.

Clutch wasn't a huge fan of the track day either. It started slipping quite badly, then didn't slip at all for a couple weeks. Slipped a little the other day, but has been OK for the past week. Definitely isn't right. So the current plan is to just drop the engine, do the cambelt, water pump and clutch at the same time. Should be doable over a weekend. There's still some life left in the clutch, but it's not great. It's probably original though.

Also got a weird rear caliper issue to sort.

So, turns out that track days cost more than just the fuel and the entry price! Good fun though, I'd definitely do another one. On the subject of fuel, I worked out my MPG for the morning session - ~14MPG!

Anyway, here's some track day photos:

Looks great on track!

T-Tops, that's what they're for. I carried a TV back from curries with one side of the roof off. :mrgreen:

Aye, pushed it pretty hard considering it's on mid range road tyres!

Didn't do any super long sessions though, it was open pitlane so I did 15-20 minutes at a time. Any more than that would have overheated the tyres I think, they felt quite hot and sticky after each session, and the edges of the tread blocks had started to show signs of overheating. :lol:

Would like to try it on AD08R's or similar at some point. I'd have to polybush first though as the bushes are old, possibly OE.

Alternator definitely needs replacing. At the moment it spins freely, but it is noisy, so I'm fairly sure it's the bearings. As it's a daily, I don't really have time to attempt a DIY partial refurb, so replacement it is. Over 5 years or so of MR2 ownership, this will be the 3rd alternator (2nd on this car!), going to attempt to replace it myself this time.

So, this weekend is / was clutch and timing weekend. Big job!

Not a lot of photos of this, more time was spent cracking on and getting it done.

Saturday morning was spent getting the engine out of the car. In about 3hrs, we had this:

Image

Not bad going! A few bolts took a bit of doing to get off, nothing too unexpected for an old car.

First job was timing side. None of us have done this before. We also replaced the crankshaft seal, hardest bit was getting the old one out without damaging the block, it's a tight fit! Got that sorted though, good thing too as the existing one had started to leak.

We installed brand new tensioner pulleys and water pump. To be honest the old water pump was fine - it was completely clean on the inside. Bearing was a little noisy, but would probably have been fine for a long while yet.

Took a couple of attempts to get the belt on in the correct position, but we got there in the end. Barred the engine over a few times to double check, and it was lining up with where it was before.

Few tidying up jobs etc and preparation for clutch tomorrow (starter motor out etc), and that was Saturday done. Big thank you to Stu and Dom for all the hard work :th:

Onto Sunday - clutch change. Just me and Stu today. Again, neither of us had done this before so the learning curve was steep. We've done our research though, and had copies of the BGB and engine manuals to hand.

Took a bit of doing to get the gearbox off the block. Some persuasion with a rubber mallet and giving it a good wiggle around to free it off the dowels and it was off.

The old release bearing was noisy and felt pretty loose. Definitely didn't have much life in it! The inside of the housing was absolutely filthy (old friction material?):

Image

Cleaned up the components, applied grease where required, and installed the new release bearing. Also installed two new driveshaft seals as this is the perfect time to do it.

Onto the clutch itself. No drama here really, removed the old one, which was pretty much dead. worn down to within a fraction of a mm to the rivets:

Image

Image

It was definitely on borrowed time!

We also replaced the crankshaft oil seal on this side. Takes a bit more doing than the timing side as the thing sits in a housing, and being an oil seal, it's a very snug fit. Pain in the ar$e to do, but it leaking in 6 months time all over the clutch would be even more of a pain in the ar$e!

Replaced the clutch with a standard Exedy OE replacement clutch. No need for anything fancy on an NA.

Image

Image

Managed to get it pretty much bang on centred first time, which was nice!

Gearbox is now back on the engine, ready to go back in the car.

Rest of today was spent getting things ready to go back in the car. Replacing the ARB bushes as the existing ones were a mess (thanks to Dom for the bushes). Got a poly engine mount to go in as well.

And that's where we are.

Next update on Tuesday!

With a lot of hard work from Stu and myself, the engine is back in, and fired first time, after the fuel system had primed :yahoo:

New clutch is very different to the old one. Ridiculously springy by comparison. Will take a bit of getting used to.

Only thing that isn't right now is rattly undertrays. Time to drill out and replace bolts!

Nice work mate. Big sense of achievement when ever you complete a big job for the first time :clap:

Had a long weekend up in Norfolk with Henry and John. One of Henry's friends owns a boat restoration business on The Broads, and very kindly made some room for us to work on our cars. We all had our own list of things to do, some were more extensive than others. The big ones were John's cambelt, and Henry's polybushes. Polybushing is easy, I hear you say! Well yeah, but ask anyone who's worked on Henry's suspension components (Stu/Dom!) and you'll understand... That car does not like being taken apart.

I just had a 22mm Ultra Racing front ARB to fit, and a few cosmetic bits and pieces, most of my time was for helping Henry and John with theirs.

Day 1 (friday) went well, nothing to report really. We had time so we took our time with preparing everything. a solid 10/10 day all round really.

Day 2 xxxx on us from a great height. To start off with, my rear window exploded on the way to the workshop in the morning. A van going the other way flicked up a stone, and it went through my window like a bullet:

Image

Image

Obviously it's completely xxxxx, so Henry kindly delayed work on his one to help me get the window out with as little mess as possible. Surprisingly we barely dropped any on the floor, and there wasn't that much in the car either. John cracked on with getting access to his cambelt, and I was going over to assist when needed as I've done a cambelt with the engine out of the car.

Much tape was used (didn't have any duct tape annoyingly):

Image

And getting as much of the sealant off as we could:

Image

The problem we have now is obvious - It's Saturday on the easter weekend, we're our in the sticks in a workshop on the Norfolk Broads, my car has no rear window, and storm Katie was due to blow over our way very soon. This is probably a good point to mention that moods were already rather sour all round - the jubilee clip on Henry's coolant temperature plate failed just as we arrived at the workshop so it dumped a good few litres of coolant on the floor, and anyone who's DIY'ed a cambelt in situ knows how easily that job will ruin your mood...

My luck did turn though. A few messages via Facebook sourced two rear windows in breaker cars within 30 minutes of the workshop. Result! The tricky bit is getting them out in one piece. Fortunately Danny Sayer put me in contact with Chris at Hank Windscreen Specialists, who came out first thing on Easter Sunday to remove a breaker rear window (took him about 10 minutes to do, absolute pro!), and came and fitted it to my car, and only charged me £70 for his services.

So, Henry's polybushes. We started with the front end. As mentioned previously, this car does not like being taken apart. True to form, the tension rod bolts were not coming free. Breaker bar plus heat wouldn't shift it, liberal applications of plusgas wouldn't shift it, a 450nm electric impact wouldn't shift it, and an air impact that's happy to dismantle boats wouldn't shift it.
So, we removed the tension rod brackets so we could get them in the vice and really have a go at them. At one point we had an 7ft long extension on the breaker bar. We bent the breaker bar.
It's not going well. But wait, there's more! When I was putting the tension rod bracket bolts back in the car by a few threads so we don't lose them, I discovered that the captive nut for one of the front bolts had failed - there was no thread in there at all! The spot welds had failed and it was rolling around on the chassis rail.

An annoying job has now become a serious problem, as this captive nut is located in a cavity with no access.

We now have a car we cannot bolt one of the tension rod brackets back on to safely, and tension rods that we cannot get free of their brackets, with old bushes that are now ruined due to all the heat cycling.

A few solutions were proposed for the captive nut problem - Option 1 - cut through the front firewall, fix the captive nut. Option 2 - replace the captive nut with a stud, weld that in. Option 3 - cut a larger hole, and weld a nut in from below.

Option 1 is ugly, but means we don't touch the chassis rail, which is structural, and is really the 'proper' fix. Option 2 is a good alternative as we don't have to cut anything. Option 3 means cutting the chassis rail, which we weren't keen on.

Henry decided to go option 1:

Image

No rotational force is applied to it, so it will be OK just torqued up correctly - Henry will get getting it spot welded in place and a plate over the hole as soon as possible though.

That's one problem fixed. The brackets were still an issue though. In the end, we sourced some replacement brackets from Stu and just cut the tension rods out of the old brackets.


I'll write some more later on, must get back to work! Pretty long update, which is actually mostly about other peoples cars :laughing

With the new brackets on Herny's, the front end was finally back together.

Image

Moving onto the rear end, it wasn't having it. Heat, breaker bar, electric and air impact guns could not move the control arm to subframe bolt. As we didn't have a spare subframe, we decided to leave it there. Henry went to Stu's on wednesday to get it sorted with a replacement subframe. They had to cut the old subframe up to get the arms out!

Meanwhile, over at Camp Goodwood Green:

Image

John has access to his cambelt! Lots of things slowed us down here. First off, the crank pulley bolt was ridiculously tight. On my car, and the breaker engine Stu and I practiced on, the pulley bolt came of with a couple of pulses with an impact gun, no problem. John's wasn't having it. In the end we did the starter motor trick, where we cranked the engine with the EFI fuse removed, with an impact socket and a breaker bar against the floor to crack the nut off. Other issues included stubborn timing cover bolts (only M6's so you have to be careful with them), and a lot of swearing getting the engine hanger free with the car in situ. What didn't help is that the guide we were following was missing some steps, and the BGB assumes you've got the engine out of the car.

Anyway, after much swearing and some blood sacrafices, we had the belt on. Barred it over a couple times, and the intake cam is a tooth out. At this point there was a, erm, enthusiastic exhange between myself and John. Essentially, we were both trying to do it in a different way. John had marked the belt with match marks which is great for making sure the belt goes on in the right place, but and once you bar the engine over these are going to take an age to come back round exactly due to the pulley ratios as it's a DOHC engine with two pumps driven off the belt. The only bit that matters is that the cam marks and pulley all align up again at cyl1 TDC once you've barred it over 720 degrees. At this point, any match marks you've made on the belt won't come round in the same place.
2nd attempt at getting it lined up was spot on though, and the car fired up first time once we had it back together enough to test it. This just left John to put it back together (with assistance from me and Henry where required).

This is the setup we were working in:

Image

It's was so nice to actually have some space, light, and shelter while working!

The location was lovely as well:

Image

At some point during all of this, I fitted a 22mm Ultra Racing front ARB. Nothing to report here - it was the only thing that went with no drama I think!

Finally, on Tuesday morning, we had all the cars back on the road (after a 2am finish the night before). Mine is running really nicely - turns out it's actually got a bit of ignition advance dialled in at about 12-13 degrees, which may explain why it seems a bit quicker than most NA's.
Henry's is running much nicer with stronger boost now - he must have had a slight boost leak before as the only thing he's done in that area is take off all the boost piping and the throttle body to change the valve cover gasket. Sounds so naughty now with the turbo flutter, which it wasn't doing before. Handles much nice now as well, just needs an alignment.
John's is running well after the cambelt change, engine sounds happier and is firing up better due to a cleaned out throttle body and IACV. He's got a pulsing/whistling noise under load at higher revs, which can only be a slight leak on the exhaust or possible intake - he fitted a new downpipe, and all the ACIS and top half of the intake manifold had been off while changing the valve cover gasket, shouldn't take too long to isolate and fix. Will be spot on then!

So, a very long weekend, and I'd certainly had enough at points, as had John and Henry. Enjoyed it overall though, even though I was pretty broken on Tuesday morning! Looking forward to next time :clapping:

Thanks Pete!

It was no drama really, just a bit of stress release as it was getting on a bit in the day, and we were behind schedule due to day two issues. Once vented all was well, and a logical approach sorted the issue nicely :thumleft:
