Help with rear valve cover.

Help with rear valve cover. **UPDATE**

So I had my intake manifold and valve covers powder coated. When I took the covers home to prep it for installation, I noticed one of the corners was chipped. The thing is corner that broke is powder coated. Anyways I decided to install the valve covers, and there was no oil leak as I was letting the engine warm up. When I went for a drive thought, I noticed a ton of smoke coming from my rear vent under the window.

I took a photo and it the gasket ballooned out when the oil pressure goes up.



Here is what it looks like when I took the cover off.



Here is what the inside of the valve cover look like.



Here is what it is suppose to look like.



So my question is this, I can't tell if the valve cover was always chipped and I did a improper install, or did this happen during transit? I am not trying to point blame on anyone, I just want to know if I can reuse this valve cover? If I can fix it, or if I have to replace it. If I replace it, they say the NA1 valve cover is discontinued and I have to use the NA2 one which I have no problems with it. I just want to know how to reroute the PCV system since I heard it was different.

Thanks guys.

I understand these are made of Magnesium. Surely it's repairable by a reputable welding shop, but you'll have to have it re-powder coated.

Right now I am looking at the photos of the NA2 rear valve cover and the there is a pcv valve coming out of it. I am just looking at worst case scenario here, but I have no clue on how to route this thing if I get it.

Before you give up on that valve cover you might try to mold a filler piece from JB Weld
You could use a piece of the rubber gasket on one side and some heavy tape on the other to make the mold.
Then you could build up the JB Weld to slightly larger than needed, then file it down to the finished size.
If it works it would save you a lot.

I considered doing that but with a piece of metal as a filler piece.

FWIW, I stopped running my PCV early last year. I now have a small nice breather filter on each VC. At the time I cleaned the filth from my throttle body and to this day {yes I check it} it is still spotless. I get zero smell, and nothing gets recirculated back through my intake/valves/ ect.

I have an update. I was going to get a used valve cover from umbrella because the dealer did not have any in this country. Before I jumped the gun to call umbrella, I got a lead from the powder coating place on a good welding shop. He was able to fill in the missing pieces on the valve.







Here it is after it was repowder coated.







So for the record, magnesium is repairable.

A really nice job and good to know these can be repaired.
Beats my JB Weld suggestion for sure :smile:

Ditto, I had recommended Umbrella and suggested just get another one. This sure looks like a good viable repair.

Could you post the name of the shop? I had a valve cover welded as well and it didn't turn out nearly as nice.

I'm glad I could help, he he he!:tongue:

Sorry greenberet, this guy is a one man operation. He literally has to work two jobs to stay a float. I only got charged $40 for the repair, but here is his information for any local guys that might be interested. Ignore what Google says his hours are, it is actually monday-friday 9:30 a.m to 2:30 p.m, and that it.

I have heard people complain about getting them powdercoated and they bake it to long or something and it breaks atleast 5 people in person.. that's why I don't understand the big deal of getting it coated

but atleast we know now it can be repaired how much was the repair?
