You'll be removing the accordion pipe between the VC and the rear turbo inlet tube to install an OCC. Once you have the engine beauty cover off and look towards the back of the engine by the firewall, it'll become painfully obvious where it is.

The PCV is located under a black, cone-shaped cap at the top of your first photo, coming out to the left of the rounded housing and partially obscured by a fuel line on the left.

Do you guys think i should install an occ to further reduce oil contaminants in the car or should i just do a periodic valve cleaning now and then and stick with just installing the rb pcv?…btw this is a pic of the oil sitting on top of the valve cover along the coil packs so i assume its main leak is from the middle location of the valve cover (inside the "U" shaped gasket)…hopefully the install goes well

wow never seen one this bad !

I know, it really does get a lot worse if you don't act on fixing it fast, its been almost a month since i first started noticing the burnt smell, but been so busy with work, I never got around to doing it. My plan is to install it the vcg and pvc valve, drive for 2 weeks, then remove the engine cover to confirm no more leaks and continue with the other maintenance stuff like replacing the ofhg and installing new spark plugs.

I did this job a couple weeks ago. It is definitely a workout. Take your time... especially when putting in the cover bots. Make sure you have a lot of sockets and extensions/wobblers etc. You'll need a lot of tools.

Also.. make sure you completely remove the bolts from the cover when you're taking the cover off. I didn't and was pulling and prying like crazy and once I removed all the bolts compoletely out of the cover I was able to get the cover off. I used a rubber mallet to break it free along with a plastic putty knife.

I did the RB PCV valve.

So far.. including an 800 mile round trip to the coast.... the car is running perfect! No leaks. No more smell when the heater comes on... or bad smell outside the car. I replaced the entire cover and gasket just so I don't have to mess with it again.

Very satisfied and thankful to Robc for the stellar DIY!

Also... don't pull the coils out until you remove the fuel rail. I failed to do it in that order and ended up with a bunch of fuel drowning and built up on a couple of my rear spark plugs. Had to soak them quite a bit to get that fuel out.

Were your cars smoking before the valve cover replacement?

My car was smoking a lot so I replaced the entire valve cover. Its been two weeks and the cars smokes less....but still smokes when the oil is cold. It seems to stop when the car is at full operating temp.

What should I do next?

OCC, RB valve & cap.

I would get occasional smoke from the passenger front of the car at a stop on an incline. The biggest clue as the smell of the burning oil both around the outside of the car and also when I turned on the heater.

I'd get a BMS OCC, RB PCV Valve and also check your oil filter housing gasket if that hasn't been done yet.

I have the BMS OCC and recently inspected it. The "out" side was bone dry and the can had some oil in it.

I'll do the RB valve and cap next. Car currently smokes out of the driver side exhaust when coming to a stop and idling. Only happens when the oil is still warming up.

My smoke comes from the driver side exhaust for the most part. Sometimes I see it smoking from both exhausts.

Can the oil filter housing gasket cause smoking from the exhaust? I have not replaced that one yet.

could be a turbo seal, could be just burning condensation out of the exhaust it even condensation in the oil.

took the car to dealership and they checked the turbo and said it was "good". I have no idea what they check or how they check it.

Its not condensation out of the exhaust. When I slow down for a light or stop sign I can see a puff of smoke come out. If I leave it idling and walk to the back of the car, I can see a constant stream of light smoke coming from the driver exhaust. It has a nasty smell to it. Smells like burnt oil.

If I do the same thing when I get home from the drive (when car is up to full operating temp), then I see no smoke.

I'm using the German Castrol for oil and I'm wondering if its too thin? I need to do an oil change this weekend and I plan to use Motul. Not sure which one tho.

Is the smoke blueish? FYI...I had dealer check my turbos...2 wks later I got RB'S and robbeck said I had the worst turbo seals he had seen.

What cap are you guys replacing? I'm getting my valve cover replaced this week and will do the rb check valve as well most likely. My friend that's a tech also said it would be good to replace the hose that's runs to the rear turbo inlet pipe as well.

That's the cap/cover some of us have replaced, it's the black plastic cap right underneath the last fuel line. Honestly the cap is more aesthetic than anything, but it also screws and unscrews far more easily than the OE plastic cap, which sucks.

Never a bad idea to inspect and see what the check valve looks like, it dumps directly into the rear inlet as your tech noted. Better yet, get an OCC.

Thanks for the pic! I bought the rb check valve today and noticed he sells that cap as well. You mention it screws/unscrews easier than the stock one. So what would I need to unscrew it for? I also noticed Rob sells that hose for the rear turbo inlet but I couldn't tell if it was upgraded or just a stock replacement.

Will also be adding the bms catch can asap. My AT E90 could go 7k miles before needing to add a quart (i would change it by then) now my MT E82 was down a quart after about 5k miles. Had my injectors replaced and the tech added a quart of oil for me and now 700 miles later its asking for another quart. So I'm trying to replace all my pcv parts, add a catch can, and see if I continue to lose that much oil in such a short amount if miles.

[prepster]

just finished working on my valve cover gasket replacement, looks like i will have to be reinstalling it, since there is a small droplet leak that landing on my exhaust after i turned her up today. Hopefully its just a lose bolt that i didn't tighten all the way (witch ill check tomorrow when the engine is cold)…Does anyone know if the gasket (vcg) i just installed is reusable? Meaning, removing the one i just installed and which i test drove for about 30 minutes today and reinstalling it.
