I don't know how this happened, and when I adjusted the valves a few hundred miles ago I know it wasn't like this yet but there is a chunk missing by the surface where the gasket seats against it. I also noticed tiny metallic pieces in the oil that collects in the valve covers. Also after driving for a while the cover leaks oil like crazy, the entire heater box is covered. How could this have happened? And is there any way I can fix it? Mainly the leaking problem? I don't want to buy a whole new head since its a performance one and I can't afford it.

| Aviation sealer on the valve cover to hold the seal in place would help with leak. Looks like there is plenty of metal to seal the cover to head. As far as the damage are you missing any part of the rockets or adjusters that maybe came off and could got knocked into the spot? Also definitely change your oil and see if there is metal flake in it. Could be disastrous on your bearings if there is. Or a sign of bigger trouble. |

| Any damage/marks to the inside of the cover? |

| If's not leaking, motor on. |

I had a problem with leaking valve cover gaskets, and here is what I did:
I used Gasgacinch on the clean and dry lower section of the valve cover only. Do NOT put any sealer on the head surface, or the side of the gasket that touches the head.
I also made sure my bales were nice and tight.
I replaced my old valve covers with new ones from Bughaus. Not all new stock-type valve covers are made equal. Some new VW-stamped covers actually have a slightly beveled interior sealing edge that is prone to leaking. The ones I got from Bughaus are far superior, in that they are completely flat (not too much to ask, right?).
Use Wolfsburg West silicone gaskets, or German cork-rubber.
No more leaks for me.
That chip doesn’t look too bad to me—if you follow the direction above.

| If you adjust the bail to put the right amount of pressure on the valve cover, and use the stock rubber/cork seals, using a VERY light smear of great on both sides, it will probably never leak. |

| That hose with a clamp on it, vented valve cover? Hose nipple, part of the cover or attatched thru a hole in the cover? A leak there might seem like a cover gasket leak. |

What Cusser said.
Relax, it's not then end of the world. You'll be able to make it seal. Play with it.
Make sure the cover fits well and square without too much up/down side to side movement. Bend accordingly.
Make sure you get good quality and good fitting gaskets. Use sealer to 'glue' gasket onto the cover. Hold gasket down and in place with spring clothes pins or little metal spring clips until it dries on the cover.
Use OEM covers if you have them. They have a better/wider gasket surface. Make sure you have strong spring bails that press squarely on the cover. Bails should snap on and off like they would take off your finger if you ever got a finger in the way.
I've sealed worse. |
