leaking rear main seal
Permalink  
 


The rear main seal on my 68 Chevy II is leaking a bit. I'm thinking probably from the car not being driven enough.

The engine was built in 1985 and has fewer than 10,000 miles on it in that time. Everything was nice and dry up till last summer.

Bar's Leaks has a product called 1040 Grey Rear Main Seal Repair Concentrate.

I'm wondering if anyone has any experience with it. Sure would be a lot less hassle than replacing the seal.

Any feedback is greatly appreciated.

thanks,

Brian

I have had good luck with Lucas Oil products and trust them. They have and engine oil stop leak product. Good reviews at Summit I'd say for 10 bucks, what have you got to lose?

so far on a sample of 2 we're split 50 / 50...

my initial thoughts sided with Pat, for $10 what have I got to lose but I'm curious Bisqik, you don't say what kind of problems the sealer will cause - any specifics?

thanks for taking the time to chip in guys

Well this stuff is designed to stop leaks so it coats all the seals and gaskets in the car ngine and is only a temporary fix. Just my 2 cents worth I don't want that stuff coating all my gaskets and internal engine parts and I am just a firm believer in if your going to fix it fix it right

i agree, fix it right or live with it. whatever quick fix you use will affect everything.

...not recommending this...an old transmission seal fix is to add a pint of brake fluid, swells the rubber seals, who knows what is in the leak stop additives?
