I think the Bentley says 145-190psi is the acceptable range, so you should be fine.

I'm not questioning Bently here, but the dry compression test results on my car at 220K was around ~205 to 210 on all 4 cylinders.

Now at 260k miles and is still going strong..

I think your numbers are what they say a fresh engine will have. So I guess you've got a well put together engine in there.

160 is great. Don't let anyone tell you otherwise. The most important thing, though, is that they are consistent. If all cylinders are are within 20% or so there is nothing wrong

yea, 160 is golden, especially the fact that they are all 160.

ohh I forgot that was you I talked to...is the car still smoking? like I said then, leak down will let you know if your valve stem seals are leaking. if not, I say its your turbo seals. obviously your rings are fine if you have 160 across the board

Oh ok.... no worries.... so no need to.do leak down test? Yea its still but less and less.... I.spome with one guy localy where I got those PCV VALVES from and he told.me that it will take a time to vlear, as he suspect that oil was going straight in the turbo ...... or something like that.

Do you have a loss of power or something? Do a boost leak test.

I didnt say dont do a leak down test. if your car is still smoking, I recommend a leak down. it will tell you if you have any bad vakve stem seals, or carbon deposit on your valve not letting it close all the way. if leak down comes back fine, I say its your turbo seals.

No I dont .... just I had blue smoke coming from my engine on take of after idle, after stopping on taffic lights, for example. I changed PCV valves and T shape And S shape components. Still some blue smoke coming but less and less every day.

If there is less and less smoke every day, it's possible you are burning off residual oil from the previous bad components. Maybe wait a couple more days, and if the smoke continues to lessen (or disappear) then you'll be in good shape.

If it is indeed valve stem seals, I imagine this will get worse over time, and the burning of oil won't hurt much except your catalytic converter.

I don't have catalytic converter,i install test/downpipe..... Yea its getting less and less... When i look in the mirror after take of i can hardly see anything. Before it was almost embarrassing ... Heheeh..... I love this car and planing to go with stage 3 upgrade soon.... After holiday in europe.... [:D][:D][:D][:D][:D][:D]

Silly question everyone... How do you do a compression test? I know there's a tool for it but that's about it....

How does a leak down test tell you have leaking stem seals?
