since the injectors are basically "shut off" during deceleration, no combustion is taking place which is what provides a strong seal between the piston rings and cylinder walls. My engine is burning oil ONLY when decelerating while in gear. Then at the light or where ever i just decelerated too it burns off the excess oil that got into the combustion chamber, exhaust become 100% normal. It wont happen untill another deceartion period while in gear......weird, i have done a compression and leakdown test and passed with flying colors, 220 across all 4 cylinder and each held it for a long time with no drop in pressure. What do you guys think? is this normal ?

its an ap1, i just swapped in a 2002 engine which i purchased with aprox 100miles on it, i have put about 430miles on it so far and i am running DINO oil at the moment.

any feedback guys ? this happen to any of you?

 

classic valve stem seal symptoms

 

Valve seals ...

thanks guys, i drove it home today the exact same way and it didnt burn any oil. the motor has less than 1500 miles on it but it sat for7 years, could that have rotted the seals ?

 

Did you remove the valve cover?
How did it look?
Were there any deposits at places where the oil had been sitting for 7 years?

As long as those deposits - if there were any - are soft they won't damage the seals but it will make them seal less until it wears away.

 

ya i did remove it and it was clean as a whistle !!!!!


today i drive the car as hard as i have yet, which wasnt too hard just got on it 1st-5th went to go into 6th and i lost like 3inches in clutch pedal travel........drove it home bled the clutch and adjusted the master cylinder arm and things are normal, what would cause this? air buble that got worked out?

 

my guess....the seals needed some time/heat to seat themselves well...or they are bad

 

ya i was thinkin this too, it hasnt done it since so who knows, il keep an eye on it.....thanks for the feedback.
