Comp or leak down test? - Page 3

Well as it's rings, it's really a new short block. As no idea how long it's been like that. But the labour involved would probably outweigh the cost of a new engine. New pistons, rings, crank etc etc will be a lot! And then it would need a new head gasket, and possibly head.

I'm not a mechanic, but have worked on engines and have a pretty good understanding.

NJ has been very good, so he is taking it back for testing. But ultimately only one solution. Which to be fair I'm gutted with, as spend a fair amount of money and time on it as well. So really not happy

Sorry to hear that, but it appears NJ is doing a good job of helping out.

He is to be fair. So more than happy with him, just wish I had a CSL to drive.

Do you have BMW warranty with the car, or just what NJ is offering.

No BMW warranty. Never thought I would need it to be fair.

Will just be head gasket. Putting oil down the bores will seal the gap where the gasket has blown. Get a second opinion! I'd put money on it, and I'm a tight c*nt so that should say a lot

Im on the second one now! The oil would push out the other side, as the tolerance is different with the piston rings.

Dont get me wrong, i was hoping so much it was the HG, but again with all 6 cylinders being down on compression, and the engine running very lean. I really dont know. I can only go by the techs word, and the gaskets are rare, let alone being all 5 points being broken. Saying that, so are rings.

And with cylinders 2/3/4/5 having two points gone, all them went right up as well.

If the head is removed, then thats just cost me half a rebuild, to which only i can pay for. The car owes me 2k in bits ive done, so call me reluctant to stick anymore into it when the everyone is telling me its rings.

Arr I assumed it was just one or two cylinders down on compression not all of them. If rings I'd guess and say its had a replacement engine at some point that's been to the moon and back.

Plus when oil was added in two cranks went to 160!

Never heard of rings, but 100% it is.

James at Bromspec is in my eyes the best mechanic ive ever spoken to. He said it all along, and to be fair i could not believe it when he was right. But just been on the phone to him for another 45 mins going through it. Owe him so much, as hes been a legend through it.

What i dont want is a second hand block with 2000000000 miles on it! So it would have to be a new engine.
