Ok as the title says...
Just to give a quick run up on the car,
stock rebuilt 6bolt, engine broke in with motoman technique... Regular 10w40 oil used so far. 4k miles on it so far, been having oil smoking out
exhaust problems for 3 of those 4thousand miles, at first ignored it and
just kept putting more oil in assuming it was a bad 14b turbo...Upgraded
to a evo316g..Nope still smokes... Intercooler piping and core free of oil,
I even installed a 3dollar fuel filter catch can on the vacuum hose that runs to the valve cover and intake arm and doesnt ever catch a drop of oil. Leading me to not much blow by, yet I also changed my pcv valve and the smoking went down from a 8 out of 10 to a 5 out of 10... But still smokes way more than it should... I have no balance shafts and high oil pressure ( yet turbo feed still tapped to head in stock config. ) I then ported the relief valve to lower oil pressure back to normal acceptable pressure and even removed the turbo return hose and cleaned it out because I found a little bit of silicone protruding over the inlet/outlet hole, put it back together and drove it...It had no effect on the smoking... The evo3 has zero shaftplay...
I then removed the exhaust manifold to check for oil leakage around the ports ( in checking for bad valve stem seals)... Funny thing is there was oil residue on the back of the ex mani gasket but none in the ports, i even felt around in there for any signs of oil and none found... ( Didnt check intake ports.)
So now im getting stumped to what it is even though i feel like ive eliminated most possibilities except bad rings, or valve stem seals at this point...
2k miles ago compression was perfect but dont know how it is now. I need to do a leak down test but havent yet...The car pulls too good to be bad rings I think, but a crack oil ring land or something...possible...
It doesnt smoke at idle at all but it misses every once and a while at idle barely noticable miss, but im actually assuming it misses at idle because the exhaust makes a faint popping noise here and there..( I have full 3in exhaust no cat or muffler by the way.)
Well It smokes pretty bad under decelleration, and even worse under boost. The smoke never looks blue ( like most burning oil sympthoms appear ) The Smoke is always grayish looking....
A leakdown test would be my best bet i know, but will be at least another week before I can by the tester, in the meantime, Any opinions, help, or experiences with this most ANNOYING and stressful issue...?
