Hi guys,
I think my engine might be done.
All of a sudden, it started running really rough and having had a compression test done, cylinders 1 and 2 are running around 190psi.
Cylinders 3 and 4 are running on about 25!!
Has anyone come across this before? Am I missing something simple or is this it for my MR2?
Thanks,
James

Re: Is my engine dead?
Certainly sounds like theres something wrong if you have no compression on 2 cylinders, it's likely to indicate an air path between those two cylinders most probably due to a head gasket breach although there are other possible causes.

leak down test it to pin point where the loss is

Bet it's rings or something that's caused damage to them. But not a good sign!
Good luck. Hope it's a head gasket, but I have my doubts.
About the only thing to do is take the head off to see what's going on.

Re: Is my engine dead?
Thanks guys.
It turns out there is a slight groove in the engine block around cylinder 4.
It's cheaper to get a replacement engine...
On that note, does anyone want to buy a 1987 MR2 engine?
2 good cylinders...😉

Is the groove in the barrel? I'm interested if it's on the deck.

A groove on the flat of the block where it would meet the head gasket.

Not at the moment.
It's coming out of my car in a few days. I'll get the cylinder head back off once it's out and take some pics.
The little groove was initially noticed when I got the head gasket done a couple of years ago but it would have been a mission to get the block skimmed too so we decided to chance it and torque it down a bit more on that side.
I had two years out of it before it went...I'm sure a block skim would solve it.
