some ?'s about compression results..
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,enough oil that it started to run down the tranny. then figured some rings were broken, did a comp. test today and here are the results... d16y8
#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.. |

Really, those numbers are kind of high for a D, but my guess would be cylinder #1 is pooped. I think you can fill it up with oil though or something? :-\ Dude, I don't know though for sure. Wait for someone with expierence rather than hearsay. :y

210 psi is about 10:1 C/R ish, 155 dose seem low for a y8 dose it smoke a lot or blow oil out the valve cover breather?

first if i were you id run a compression test again, but put a teaspoon of oil in #1, if it goes up to 180+ theres your problem(bad ring) but if it stays the same i would look at getting a oil catch can to release some positve charge from the bottom side of the crank, or take a look at maybe a bad valve seal or something it can be lots, just start from the compression test and work your way down.
