Cawston,
Ok I need help my car is emitting blue smoke. I completly rebuilt the motor 3000 km ago and put a knew turbo on (from?) Evo3 16G.
All was good, I was running at the track and noticed a lot of blue smoke when i would rev it up to my dsmlink launch control.
I drive home trying to make it smoke and figure out when it would smoke, the only time i could make it smoke was downshitfing. So i get home and test the compression to my suprise its good 165psi accross the board, now im thinking turbo or valve seals so i pull of my lower IC pipe it's bone dry (this is a brand new turbo), next i pull off the exhaust manifold and find the runner on the number three cylinder has lots of brunt oil residue around one of the valves it appreas like its leaking from the seal.
One week before I had the manifold off and all the runners where dry. So i replace that seal on that valve this week however after i replace it i noticed it looked like there was a small amount of burnt oil residue on the opposite valve but it does not look like it is leaking from the stem like the other one so now im worried.
I put eveything back together and start the car. It smokes a tiny bit at start up I figure it was old oil bruning off so i let it get up to operating temp and it does not go away. I then get in the car and rev it a little as soon as i rev it the car pushes more blue smoke than ever before. Just a little tap on the throttle and lots of blue smoke (this is free reving no or very little boost).
I pull the exhasut manifold again and the same runner looks wetter than ever, it seems like it got worse. So what the hell can i do now? Is it possible that I fried or cracked the oil ring in that cylinder but the compression rings remain intact and holding compression.
anybody every heard of this?
wouldn't a cracked ring scratch the walls and wreck the cylinder causing low compression or could it have somehow imploded and just not be touching the wall anymore?
Could it be a head gasket but wouldn't i have treible compression like i said before the comprssion is perfect?
Could it still be the trubo even though all the pipes r dry and it boosts fine?
I took the O2 housing off to look for oil going past the turbo seals and could not see any why is that runner still getting wet?
sorry for all the questions but im lost and preety pissed of about this whole rebuild
