Black sludge/deposits under valve cover - problem?
IDIBRONCO - I agree. While it's out, I'll take the time to check everything and upgrade the valves. I'm sure I'll be back here with questions once I start the project. Looks like it's going to sit in the corner of the garage for a while longer before I get to it though :( I MISS DRIVING MY...- Ford420

Black sludge/deposits under valve cover - problem?
As for my valve cover gasket project... I will not be getting to the compression check after all. I decided to pull the rockers to investigate further and to check torque on the ARP head studs. Well, much to my chagrin, the #4 exhaust valve has a lot of side-to-side play in the guide. About...- Ford420

Black sludge/deposits under valve cover - problem?
Goat - That's a great find at PNP! If you need parts or want to get the unit tested and rebuilt, GV can do that - for a healthy fee of course. They may not be very cost effective, but they do support the product no matter if you bought it new from them or not.- Ford420

Black sludge/deposits under valve cover - problem?
Goat, I am hoping the buildup is just because of the cold coolant temp and infrequent use, as you point out as possible causes. I'll post the compression numbers as soon as I run the test. I really like the GV. I wired it directly to the switch on the shift lever, bypassing the GV analog...- Ford420

Black sludge/deposits under valve cover - problem?
Thanks for the reply Nero. The fact that it's only on one side and only in the middle of the head threw me off too. I suppose the compression test will tell. I am 50/50 on whether to try and clean it up with a solvent.- Ford420

Black sludge/deposits under valve cover - problem?
Long time since I last posted. Searched and didn't find anything that matched what I'm finding. The valve covers on my '86 6.9L haven't been off since the engine was rebuilt in 2010. Since then, the truck ran for a while without a turbo, then got the Banks Sidewinder system installed about 30k...- Ford420
