Oil Loss, PCV Replacement

Alright, so my speed has been eating oil, about a quart or so every like 2.5 weeks depending on how much driving. Have just recently noticed a very fault white/greyish smoked mixed in with the black smoke she blows. I'm on my second K04 with about 42k on it. She's not huffing and buffing like the first one so I'm not thinking its the turbo considering the amount of oil I'm going through and it not blowing pure white smoke. I did do a compression test back when the first turbo went, DEC 2015 and it was high 180s across the board. Cant find the paper work for the exact numbers. So I'm looking to do the PCV replace since thats on the list of possible suspects and i have no clue when that was a done last. Im looking to go from under the vehicle to remove and replace vs removing the IM. My question is, will I only need to order the PCV and the OEM PCV gasket for the job or is there something else I need to get also.
 
I would suggest pulling the manifold. You will hate life trying to do it fully assembled.

Your parts list of pcv and gasket seems complete. Maybe replace hoses if its your first time pulling them off in a decade.

Where are you located in FL?
 
yeah...it can be done from underneath but it's not easy or pleasant to fit your hands up in there. if you're feeling particularly inclined, you could double up on jobs and do a valve cleaning at the same time, to make pulling the IM more justifiable. a catch can between pcv and IM isn't a bad idea, either.
 
Okay, was told i should pull the spark plugs and check them in addition to doing a compression/leak down test, yay lol

Im out in St. Augustine near Jacksonville
 
Thats a bit too far for me to randomly drive over. I'm Melbourne area.
 
Pull the manifold. Doing the under-the-car-no-manifold-removal is for folks with child like hands. If your PCV has failed, you'd have a good sized amount of oil in your manifold.

Pretty sure @Raider has my old PCV plate and valve in his attic. That would make it super quick for swap.

I've got a new pcv. I give, you just send me a new one back. I've got a compression tester too. Also look into the bolt thing for the turbo to help with the pressure. Jbr and Damond sell em.

I have a friend who's gonna help me do a compression test on it this week.

Ya no child hands here, so I guess pulling the mani is a must. I'm gonna wait to see what the compression is before I start that job. I'm honestly hoping its just the turbo going again
 
pulling the mani isn't really all that hard, at least, just time intensive because there's a lot of smaller steps to getting it out.

if major blowby is the issue, wouldn't a leakdown test be more indicative of issues than compression?
 
I would do the compression test first. Sadly, losing a ringland is more common on these engines than losing a PCV valve.
 
Are you the silver Pu that I see driving around the Southside area?
 
So I was looking over the motor this afternoon, I knew I had a small leak on my timing chain cover but was never serious enough to fix. However it looks like it might have gotten worse, still not leaking any spots on the driveway though. Its leaking down the back left corner and appears to start right at or just above the alternator. Also let the mother sit and warm up and just idle, looked like I was getting a small amount of smoke coming out, on braps whites quickly followed by black soot. so possible turbo. Still waiting to do a compression test, little hectic with he holidays and such.
 
I've had that same oil leak/mist for 4 years. I've tightened down everything I could get to on the timing cover and valve cover without removing the alternator and belt pulleys. Never seemed to be a huge problem since it barely eats oil. Once a year I have to give the crank sensor a quick spray of electronic cleaner. Otherwise no major issue.
 
Don't need child hands to do underneath. Make sure to get the ring that holds the pcv in the plate. If you're just replacing the pcv yoo can break the old ring, pull the old pcv then put new pcv and ring. Is it easier to reach with manifold off, absolutely but I'm too damn lazy to take mine off.
