All over for G164 CKV... didn't make the moon after all.

[PW@Woodsport]

Sorry Luke just going off the info being posted , I'm sure you would agree a car running fine and parked up cant suffer a seized crank all on its own, there appears to be more going on now though.

Hey Rob, free Rev2 starter motor here if you need it mate.

[Race Idiot]

Theres a whole rev 4 turbo drivetrain lying around at lukes

[Driftlimits Performance]

yes Paul that's a given.

[Charged]

Come on Rob, -£250 for a replacement 3SGE which will see you another 100,000! It's just the engine you need, seems daft to buy a new car unless there are other reasons you want out?

+1.

Perfect excuse also to whack a 3S-GTE in there!

[Moo]

Gutted. Hope you get it sorted one way or the other

224000 miles on an engine is good going these days
i see loads that let go after 80 or 90 thou,
admittedly not Toyota,except maybe later corollas and estima diesels.

If the body and chassis are still good then it deserves another go.

Any ideas anyone?

Any ideas anyone?

After 13 years of ownership you'd be mad to move on and forget about your MR2. For a period of approx 10 years I've had 6 MR2s and sold my most recent one a few months ago. That said, I wouldn't have another, unless I could get my hands on G905APB again.

I've had my Mercedes W123 230E for coming up to 3 years now, in which time we enjoyed taking my wife to hospital and bringing her and my son home for the first time as well as a 3000 mile trip around Europe, amongst many other memorable journeys. I will never part with my Merc. Surely you feel the same way about your MR2?

[blue2]

Im with everyone on here, fix fix fix! Would be a shame to scrap it after so long! You could always drop a V6 in there, thats what i did when i got bored!

[HighwayStar]

Well after investigations I'm told it simply is that the crank has siezed, regardless Paul of your conviction that that can't happen.
Has anyone anywhere out there got any ideas how this can happen when it drove beautifully home with no lights or warnings on and sounding fabulous yet still apparently next day...seized up on the drive?
I've decided it won't be fixed. There are only so many times I can persevere before the intelligent thing to do pushes it's way to the fore. It had new suspension, interior, HG etc over the years rather than being replaced but now I just can't be bothered trying to maintain something when it appears it's not possible even to figure out how or why it went wrong.
Something doesn't add up and I can no longer motivate myself to get to the bottom of it.
All mods are likely to be for sale v. soon from leather interior to suspension and lights etc. Details can all be found in my garage and all but the Rogue lights will come with their original invoice/receipt.
Dismal day.

Need someone independent to look at it... Where are you based?

[PW@Woodsport]

That just doesn't make sense, a perfectly running engine just can't seize up overnight on your driveway!

I'm sure Luke has diagnosed it as a seized crank properly, but it still doesn't add up.

[Super_red]

Why not? If it had run dry of oil and was red hot inside when parked up then it will seize as its cooled down.

Damage often occurs to cars only during the warm up/cool down phase.

[PW@Woodsport]

If it was that dry of oil (which i'm pretty sure it wasn't) it would have nipped up very quickly the day before while being driven.

and was red hot inside when parked up then it will seize as its cooled down

Can you explain in mechanical terms how that happens? As far as i'm aware metal expands when hot (ie the crank journal) and metal contracts when cold.... so how can it seize when cold if it didn't seize when hot?

[Slarty]

I guess it's possible that it hydraulic locked, bending the crank/conrod in the process? If, as Luke said, cylinder 4 was full of fuel, then it I guess it'd be pretty much curtains for the engine anyway. Assuming of course that the cylinder didn't fill after the engine was stopped.

[HighwayStar]

Oil was checked the day before, just before it's last run. No warning lights came on during the run. Sounded great from beginning to end.
Could the crank have seized during the following 4/5 unsuccessful ignition attempts (2/3 with a jump pack) even though at no point did the engine turn over? As stated after one try (with the pack) even with the key removed you could hear a continuing clicking for maybe 20 seconds (solenoid?) and that was the point smoke appeared.
At the end of the day I guess it doesn't really matter how it's happened now does it.

[PW@Woodsport]

What is more likely is that some bore washing on 1 cylinder has caused that cylinder to nip up, which could i suppose happen after shutdown, but i would be very surprised if the crank itself has seized.

If that is the case you could get some oil down the bore, get it moving again, cure the overfuelling problem and you could be good again.
