Most of your oil would be coming from intake side not exhaust side because of boost and positive pressure. i would take off intake manifold and look. If it is intake valve seals you will know. They will leak alot and you will get smoke if real bad. If its's piston rings the cylinder that has problem will have signs of oil all the way down where valves seal at head.

Thanks for this info.


I posted a thread similar and ive been taking notes on this one.

Replaced guide seals on a motor thus far, seems like the ones that are completely crap are just floating around on valves they come clean off with fingers.

Others you gotta use pliers like you guys stated but I seem to think a adj crowd foot or ordinary seal puller both sides prying up on the metal retaining ring works good pushing valve seal off.

Looking at these newer updated seals and the ones that came with these isx motors, plain and simple the ones that came with the isx are complete garbage.

Any isx with these factory seals I would swap them regardless, even for the peace of mind it's well worth it

Still have concerns on lower copper seal for the injector???

Only o-rings that come when you order a kit like this are for the injector and it's the middle o-ring seal.

Ive been cleaning the bottom copper cup area very good and installing the new middle o-ring on the injector itself. Also changing out the injector connector rod o-rings as well since you have to pull them back some, "I just pull them completely out"

I hope this is correct, im learning on the fly with some great help of others on this forum...

Thank you, you guys that give valid insite and guidance are awesome.
