Proper valve cover Tq

Post by Twglace »

Hey all just wondering what the proper Tq is on the valve cover... It seems I did it incorrectly and is now leaking oil

Would you happen to have the part# for the injector pump fuel screw oring? It seems to be the root cause of my fuel leak that's been coming and going... Now it's back full force and I pulled the screw and the oring is split

no idea, I'd probably just go match it up somewhere if you can pull the screw and have the remains of the O-ring. Quick poke around says diesel fuel is fine with Viton, HNBR (those green AC o-rings) and standard black nitrile. Any auto parts store worth a damn ought to have an O ring assortment with something that will get the job done.


or measure carefully and buy a bag of 100 from McMaster for 10 bucks or so.

Valve cover is very difficult to tighten, the screw against the firewall is a giant PITA. You must use good quality high temp gasket sealer and OEM gasket, best from BMW direct.

Never had a lot of luck with sealers on rubber gaskets but I think I used some flavor of gasket adhesive to glue the gasket to the cover so it would stay during assembly. Don't remember what it was specifically, but I seem to remember it looking like yellow snot. Without the glue the gasket just falls out of the cover and trying to get it all assembled properly on top of the head is basically impossible.

Not sure the firewall situation on the BMW but it overhangs on a Lincoln, and there are also heater hoses in the way. Trying to get the cover under the cowl, over the vacuum pump, and around the hoses is a huge PITA. Had to re-position it a few times to get that circle bit landed in the head correctly. Check it with a mirror before bolting things down.
