Crap load of white/greyish/blueish white smoke when i rev up

[Grumpys93]

OK i did research and found nothing that really helped. Called around and no one could find anything. So this is my last chance at solving this.

I have an f22a1 and after doing a run with another street tuner when i got home i noticed a lot of white smoke was dumping out the exhaust. I started to get scared cause i figured this was a sign the motor was gone. So i did a compression test and i got between 190-200 across the board So that made me happy. And it does not sound like a wrx. So i then looked at the spark plugs and replaced them. There was oil in one of them so i replaced the gaskets under the valve cover. Still white/greyish blueish smoke. So i then check my oil. Thick not like chocolate milk. Check coolant still good and high.

I then do another compression to check the motor still good across the board. So i then swapped out to my new turbo to see if it was the turbo it wasn't still smoke. So i put the old one back on.

All i can say is i am stumped. I thought it was the head gasket but it is showing no signs. I noticed some oil on the spark plug of cylinder 3. So i am going to replace the gasket under the rocker assembly today. I just have no idea what it could be.

Any ideas would be helpful.

Try Seafoaming your motor, its topped all my smoke issues.

ya that is going to be my next step after i replace the seals under the rocker assembly

isnt like this...

blue smoke=buring oil
white smoke=burning antifreeze
black smoke=too rich

valve stem seals

also try a cylinder leakdown test

start putting every cyl on TDC remove the sparkplug and insert fitting and push in compressed air and ear for a wiss

this could determine a HG, RINGS, VALVES

I forgot about that.

btw if you do, do it...

bad headgasket will make air come out radiator
bad oil seals will make air come out of the dipstick

PCV and breather also

OK wouldn't the compression test rule out hg, rings, and valves?

And my dipstick comes out all the time. I figured it was just from boost? OR does this mean the oil seals? And Oil seals are you referring to the gaskets under the rocker arm assembly?

[Grumpys93]

PCV and breather also

The PCV is blocked off on the intake mani and the hole in the valve cover is atmospheric. Wouldn't the breather have air coming out of it anyway?

I mean the seals that separate the inside of the piston chamber from the oil chamber, ie=piston oil ring, valve seals


and did bubbles of air come out of the radiator cap hole when you pressurised each of the cyclinders?
& what color was the smoke? cuz I dont think it would come out in many colors like you said it did

If your dipstick is popping out, don't you think it's time to get a better breather setup and catch can?

Do a leak down test. They are much more conclusive than a compression test.

he did that test already. & yeah if you DS is poping out it might be cuz your PVC is clogged causing the pressure to buld up cuz it has no were else to excape.

the pvc is blocked off. You are referring to the part that goes from the intake mani to the valve cover right? it is capped on the intake mani and the hole on vc is atomsphericly dumped. It is not good to have the pvc connected when you are boosted. I am going to replace the seals under the rocker arm assembly and seaform the motor and we shall see what happens. Hopefully no more white smoke

Update:

Did some seafoam a lot more white smoke came out but still smoking the same. So i did my own version of a leakdown and put the compression tester in and pressurized the combustion chamber all for help at 200 after letting it sit for 2-3 minutes. At the same time i listen for an noise that may be coming from the valves and heard nothing. I am now going to take of the intake mani and see if i find any puddles of oil that could have been sitting and now are being burned off. The oil could be due to the blown turbo i was running. I will then process to clean it out and reinstall it. At the same time i am going to look at the valves and see if i see any trace of oil and if there is how badly drenched they are.

most intake mannys are dirty from, A=the PVC valve, & B the other vent tube that goes to the intake piping.


& you didnt say if any air was comming out of the radiator cap hole...
