stop leak additives for engine and transfer case

[blackbomber]

Hey guys,its the blackbomber here..original owner of 84 720 4x4 truck...wanted to ask about additives... I am looking at LUCAS  OR  BG PRODUCTS TO TRY ON engine and transfer  case...not sure where leaks are at..  have never tried a stop leak product before... BG ULTRA GUARD  is what I found for the transfer case.... can I use this on the truck..catalog says it is ok for   gl4 types of lubes..not sure ....

Just keep in mind that stop leak stuff can plug up things you don't want plugged up, like if you use it to plug a leak in the radiator, it will fix the leak, and it can plug the radiator up also.

I once used a stop leak in my engine, it fixed the small seal leak temporarily, but when it started leaking again, it was like a dam broke. :(

The best stop leak is new gaskets or seals as needed   :thumbup:

By all means , do NOT try your Grandfather's recipe of egg whites and oatmeal!

I had leaks on my transfer case. The top inlet and rear outlet. It was the synthetic oil I believe. New seals and good to go.

 

Power wash the engine and watch for where it's coming out. Front timing cover seal is easy and cheap as is the valve cover.

DO NOT USE LUCAS OR STP! I have seen that goop clog up an oil pump or heads more than once.
