It needs new tires, so I'll look further into the proper ones for it. Believe it has old Michelin LTX's on it now.
I will go through all the connectors and grounds. There's a few interior lights that are not working, when you signal both indicators on the dash flash, signal stat is pretty floppy so it will probably be replaced. The foam seal on the engine tin is in pretty poor shape as well, the engine bay in general is a mess. Probably going to pull the engine and reseal the tins before any major trip. Have to look into some type of oil temp gauge as well, probably the berg dipstick one unless there is any other suggestions.
As for the Valvecover gasket, I didn't even think of a pcv issue being the cause. It has some sort of aftermarket billet catch can thing rigged up on it, I'll take pictures tonight and see what you guys think.
