visited the track last night and friends noticed some blue smoke from exhaust during burnout and through 1st/2nd gear. when i got home there was tons of smoke from the exhaust and also noticed a good amount of oil from the valve cover breather, then figured some rings were broken. did a comp. test today and here are the results...engine is a turbo d16y8 and it is tuned.
#4---210
#3---180
#2---180
#1---155

would these results still point to broken rings? also my new oil return had a very slight upward slope which may of caused the blue smoke but not the oil from the breather, thanks for any suggestions or comments..

I'd say your rings are gone on #1. Your car being on a upward slope wouldnt cause you blowing blue ( buring oil in chamber ). Nor would it cause that excessively low test between #'s 4 and 1.

thanks for the input.. the upward slope i mentioned was the turbo oil return line though

Wouldn't matter too much; there's definitely something wrong with the #1 cyl.

did you do a wet compression test? it would help in confirming if the rings are bad or not. but from the look of it, #1 is pretty much toast. way too much of a difference between 1 and 4.

it was a dry test, also the engine was cold

You should re-test when warm. If you still get low in #1, put some oil in there. If the numbers go up, it's most likely your rings.

alright ill give that a try and post up the new #'s later.

new warm comp. results
4-----210
3-----185
2-----185
1-----175
any opinions on new #'s?

if you do a wet test, it will confirm what everything that is being said. afterall, it could be something besides the rings. its possible.

if it were mine i would want to see those 180s above 200 on a turbo car. if you havn't done it already adjust the valves dead-on with spec. even if you don't think it's leaking there it's still a good idea.
