4Star cooling leaks

Curt Cooke · Nov 26, 2012

Rebuilt motor, coolant leaks at pipes between heads and blocks. The leaks go away quick after engine is running and warm but when it cools down, they all bleed. New o-rings on corroded pipes that I smoothed with silicone. Will these leaks go away on their own or is there another simple solution. It's not serious, just annoying.

If it was mine I wouldnt be afraid of using some stop leak in it. With small leaks it can help. I used some on my M5 and it worked.

That was my plan, I just don't know what would work best, the fine particles or that pelleted gooo

Ive used Silver seal and Barrs before (pellets). The pellets do leave a muddy consistency in the antifreeze..but maybe that is why it works at times. If it is small seepage I dont think the particles would hurt to try first. I know what you mean on not knowing what works best...you just want the leak to stop..
