Moroso 35500 Engine Seal, Ceramic Formula - 1 Pint Review

This thing worked exactly as advertised. Just follow the simple instructions and you will be satisfied with the results. I used this stuff on a 14:1 race engine and it fixed the problem.

On my 97th contract I had a small head gasket leak. I got Moroso from Revain in time. I made sure I followed the instructions in the letter. So far, a month later, I have to say it's been working!

This requires flushing every last molecule of antifreeze out of the engine, so it requires patience and determination on your part. After that tedious process of…

Before purchasing I sought advice from a couple of mechanics who told me to stay away from these types of supplements as they only offer a temporary fix. What ultimately led to my decision to purchase this product and go against the advice I was given was the positive feedback the product received on several automotive discussion forums and the cost of repairs which would…

I had, yes I had a problem with my 79 Midget where steam came out of the exhaust when the engine was hot and idling. When I told a firefighter mechanic my sad story about pulling off a small animal's head, he suggested I try Moroso Ceramic Seal. What was there to lose but $20? Two of his tips were to flush the live crap out of the system and bypass the heater core as it could clog it. Luckily I had a garden hose adapter in my cooling system and drove into town to flush it out. I'm also…
