oil in plug valley
- Thread starter Kota
- Start date
I had this same problem. I took out the 4 Allen head plugs, put black silicone around the threads and put them back in.
Then i got new cam cover gaskets about 15 bucks and took them crappy phillips head screws out and bought some metric bolts with lock washers and it been dry ever since.
I found that those phillips head screws dont stay tight and the cam cover gasket starts leaking, I was tighting them back up every 3 or 4 days.
If you do use bolts be very careful how tight you tighten them I broke my cam cover cause I tighten one to tight, I was lucky to have a spare set.
Oh and yeah the oil will deteriorate the rubber boot for the wires and might even cause the plug not to fire.

Im pretty sure there is someone that makes AF cam covers, I've seen them on MKIII before online, but I dont know of anyone. you will have to research it online.
ARZ performance makes some really nice ones! kinda pricey but worth it! i'll probably pick a set up someday.
I wouldn't replace the valve cover screws with anything other than OEM screws / washers. You don't need to torque them down, thats why they used screws to prevent them from being over tightened. Also I thought the rubber washers are because the head and covers expand differently and the rubber allows the movement. Putting lock washers won't allow for any expansion.
New valve cover gaskets will probably solve the leak. Get new valve cover hardware from driftmotion for cheap if they look like they need replaced...

Yeah, you've heard the answers already so I won't reiterate them. Just a quick tip though, make sure you clean the gasket surface of any bits of loose pieces, liquid gasket silicone goop, or anything like that before putting the new gasket down. I've seen way too many leaks caused by someone just not cleaning things up properly.
It's generally not the valve covers that leak into the spark plug valley, it's the oil galley plugs (4 hex head plugs level with the 3rd cover). The hex plugs are 14mm
