it just been getting worst ..to the point i cant even sell it for cheap to buy a 03/04 cobra..?if i hold it for 1 min at 4000 boy its like james bonds car. i heard they had the wrong v/seals on them ,on a google seach i do ..but dunno ..i dont want to pull motor if i dont have to .but i can even get the v/ cover off.midlifecrisis99cobra said:It's the 20 seconds that has me bugged. If the wiper rings were gone, why would it wait 20 seconds? Is it possible that oil is being pumped into the top end of the motor and finding it's way into the cylinders? It would be real messy to try to figure out if the oil is draining properly. At least any way I know to look. Nothing else pops into my head right now. Did this problem just pop up or has it been creeping up for a while?
matter of fact i do....i heard it all. i've heard from numous engine builders ..they said i header wont make your car smoke.even paul form pauls hi po in MI. said so..i did a search long times ago..i dont know what to belive? i heard it was the coating or something in the headder? going though egr vavle..i got car used with 47,000 k on it wreaked in ft. end when i fixed it i put the headders on it at the same time. so i dont know if it smoked before the headders? i heard 99 had v/ guide problem that people just thought it was a mac problem?COBRA90GT said:What are all of your car's modifications?
Wouldn't happen to have a set of MAC longtube headers installed, would you?

well here what i dont while back i disconnected the pcv pluged the vac souce and put a breather in the driver side v cover still does the same thing ?? heres where im at .....i took off intake.it seems to be alot of oil on top of the vavles..all the ones that are closed have oil pullded aroung them?? what you think if the heads come off stock manifolds are going back on ...feed back please ...also now that my car is torn apart,i found a 03 cobra vert ..i knoew this was going to happen..should i put v seals on my 99 than sell it ?86bluecobra said:no chance that you are sucking a bunch of oil in through the pcv? can you look where the pcv enters intake to see if there is excessive oil slug there? I'm not completely fimilar with the modular motor but i know this can be a problem on the 302's. I would rule it out before i ripped engine out. See i suspect it because maybe in the 20 seconds you are building the crank pressures up and they along with oil are being sucked by the pcv.

25 to 30 seconds ass munchBurningRubber said:Dont mean to resurrect the thread, but why are you holding the engine at 4k for a minute?
That kind of abuse will waste an engine even at low miles if done enough. Holding at those RPM's, or constantly being revved out is hell on rings, and other seals.
