Elring. Have one on my N55, fitment was indistinguishable from OEM and costs a fraction of the BMW one.
Pros: indistinguishable from OEM
The valve cover tends to leak also. Be sure to use Toyota FIPG sealer and ensure the distributor seal is intact.
Pros: ensure distributor seal
Cons: valve cover tends leak
Vehicle:
Toyota Camry
I had mine replaced at the dealership 5 or 6 yrs ago they were in there for the gasket and went ahead and put a new valve cover on as well. It’s held up perfectly not a drop of oil lost.
Pros: held up perfectly, no oil lost
Vehicle:
BMW
If you buy a new valve cover definitely get a OEM or VAICO one.
Pros: reliable engines
Cons: failed PCV
After removing the valve cover to try the above suggestions, I realized it was such a pain in the ass that I wasn't gonna do it again. So, I ordered a new valve cover...aka nearly $600 PCV valve. A week later I reinstalled it. That was a month ago. No more codes.
Pros: no more codes
Cons: annoying to remove
Vehicle:
Audi
Today I thoroughly went through and around the block and finally found a leak which is common on the back side of the valve cover and sourced it all the way towards the front corner that’s hidden in the opening between the valve cover and timing cover so needs a new valve cover, and possibly a new coil as cylinder 1 was mis firing and probably from the oil getting onto the coil
Pros: found valve cover leak
Cons: cylinder 1 misfiring
Vehicle:
Volkswagen Passat
had an 04 civic with a hole melted in the valve cover somehow
Cons: melted hole in cover
Vehicle:
Honda Civic
Well- the valve cover is FULL of sludge! It was good I ordered a new valve cover because I had to cut the sealed area behind the valve on this one for self-discovery...there's no way I would have been able to clean it without a bucket full of degreaser...
Pros: new valve cover ordered
Cons: valve cover full of sludge
Vehicle:
Audi A6
I'm about ready to replace the valve covers on my 11 Touareg at 100k because they are leaking.
Cons: leaking
