Hey guys, my 94 Jimmy with the 4.3 vortec has a pretty small oil leak but I still have to keep a piece of plywood under the truck to avoid staining my driveway. I've seen a bunch of oil additives that claim to stop engine oil leaks at auto parts stores so I was wondering if it would be worthwhile to try one of these. Thanks!

 

bump... nothing?

 

Well the stop leak additives are just a Bandaid. There are some additives that do prolong the repair, but its just a matter of time You are going to have to do the repair to correct the Problem. It is the rear main seal I guess ?

 

Clean you engine and pin point the source of the leak. It may be something quick and easy...

 

try some Lucas Heavy Duty Oil Stabilizer. lots of guys use it on here, i personally love it.

 

Could just be the remote oil filter lines - they tend to leak at the crimps.

x2 on fixing the problem instead of adding mechanic in a bottle.

 

I agree with fixing it instead of pouring something in it. If it sops the leak, what else is it stopping up too?
