October 30, 20169 yr Evening all That time on a Sunday where I like causing misery towards myself.. I have just done a compression test on my car, and the results were, erm, well depressing i'd say. 100 psi average.. So the question is since you are the guys in the know, where is the best / fairest place to get engine parts for it? Thinking of forging whilst i'm in there, but would like to price up costs ect. Thank you in advance
October 30, 20169 yr When you say average, what were the actual numbers? Why did you perform the test? Is the car showing symptoms of poor health? Is your testing equipment calibrated or verified?
October 30, 20169 yr Author 105psi, 95 psi, 100 psi ect It cranks over very quickly and didn't sound over healthy when I started it earlier, so thought i'd check it. Must admit the equipment isn't calibrated. Can't see it being 50psi out though
October 30, 20169 yr Agreed. Just seems a touch odd that it's uniformly low. Is it exceptionally high mileage? Does it burn oil? Generally I've seen these engines fail on a cylinder or two rather than evenly though out. I've got a 60k block sat I'm my workshop at present that still has very clean clear hone marks on the bores and the ring gap was well within factory spec. What I'm getting at is that for an average mileage engine I'd be surprised if the rings are worn out evenly through use as apposed to mechanical failure. I suppose it might have suffered from oil starvation but then I'd expect bottom end damage too.
October 30, 20169 yr Author I see what you mean. I think the previous owner may have abused it, it has a boost controller in it that goes up to 1.4 bar, stock turbos, stock guts in the engine ect. It uses a small amount of oil yes, but you don't see any cloud of smoke bellowing out of the exhaust. The mileage is 109,000. A little high yes, but I didn't pay much for the car at all, and did expect having to pull the engine out at some point. I did only run a test on 3 cylinders, didn't want to break my heart anymore today
October 30, 20169 yr More investigation required IMO before shelling out to rebuild it. Esp if you've only tested half the engine. If you had less than 100psi on all cylinders I'd expect blue smoke on over run and probably grey smoke on idle as well due to excessive blow by. Be well worth you having the car health checked by an expert in these cars. Edited October 30, 20169 yr by Stephen
