Need recommendations for a really good RTV sealant for sealing up oil leak.
I've got a Nissan 4cyl OHC with the front timing cover 'sandwiched' between the head and the oil pan. It's got a nasty little leak right at the top just about where the the cam sprocket likely slings the oil. I REALLY don't want to take this thing off to fix that darn leak.
I know exactly where the leak is, can access it from the outside and likely can get some degree of access from inside (w/ valve cover off): Idea is to clean as thoroughly as I can and squirt/dab/whatever some really good sealant in either side of where the timing cover mates to the head and let it set, cure and hopefully solve the problem. Doesn't have to look pretty just, needs to work and save me the hassle of taking the cover off and possibly pulling the head or lifting the engine enough to get the oil pan off.
I've had good luck with the gray 'import' RTV. Any others that might be better...? Particular brands? Types? Other types of sealants besides RTV for this?
BTW both the timing cover and the head are aluminum.
Appreciate a recommendation for a the best RTV type/brand that is up for the task and will last.
thanks
