Yea but this isnt an alternator were talking about. And i checked everything before it went in
So im pretty confident the valves guides and seals are fine. It also doesnt smoke at all on start up and will ilde all day with nothing. Even if you blip the throttle a few times or hold rpm for a few seconds.

on an engine that only has 30k, why are you doing these things anyway, racing? using it for a getaway vehicle? taking the kids to school? haha

Ahh, ok, I just read up to see how I got here, Someone else had posted that and I was in reply to them, not to you sir :)

Ok, I just read up farther, it was something you had written, post #3, and i was only joking about your remark, hard engine braking and rigorous drives :)

Couple things to check, and do.

2.9l's hate eating oil. Despise it, in fact. Catch can the thing before it builds as much crust inside the intakes as rusty's


In order, I'd bet on residual oil scum/pcv BS as A 60% chance of being your cause, followed by rings as 20%. What was the reason for your head gaskets? Compression tests will show good with "meh" rings. When you're working the lungs hard is when blow by will occur. Makes sense to me.

Last time you ran a can of aerosol seafoam through your intake? The liquid won't do much for a 2.9. They LOVE the aerosol stuff, though. I run a catch can and water/methanol injection on mine. I still run a can of seafoam every other oil change, and a bottle of motor flush every time. 2.9s hate three things: heat, dirt, breathing oil. Fix those and you have a few million miles left in her.

No matter your cause, catch can will stop nearly all oil vapors coming into your intake. Just put it in a cold spot in the engine bay. Mine is over by the clutch reservoir now. Works much better then when it was on the intake.

I couldnt tell where my issue was coming from so i did head gaskets and valve seals at the same time. Also was easier to do the valves with the head off. Didnt seem to do anything for me.

I was planning to do a catch can to see what i would get. Ill report back on this and plugs when i get a day under the hood.

I would have checked for a leaky injector before going to all that trouble.
