Loctite 574 Flange Sealant - 50 ml

Used it to reseal a balance shaft housing on my 1987 Porsche 944, worked awesome and haven't had any leaks whatsoever. Just make sure the surfaces are totally clean before applying, I used mineral spirits and carb cleaner to clean the mating surfaces.Just run a mild bead and let the housing squish out the excess, trying to roll it on or smear it after applying just makes a mess. This stuff is designed to wash away in hot oil so don't worry about excess getting squeezed out. Would use it for any metal to metal sealing.

This is amazing stuff. It doesn't harden unless pressed between two metal surfaces. Used this stuff to rebuild my Porsche air cooled engine and have zero leaks now. Be warned, this stuff is the consistency of snot and it only takes a very thin layer to do the job. I bought a small foam roller from Home Depot to get a uniform thin layer on the cam towers.

Only seals when compressed between the flanges. Any excess inside dissolves in oil. Yamabond, RTV type sealants dry and can break off. Recommended by Porsche for 911 engine cases. This is the best for machined metal-to-metal sealants. Hard to find and not cheap.

Product is fine, as expected.This sealant is the factory recommended product for Porsche engine assembly.I only noticed after buying that the ETA was 2 months after I placed the order.Unclear how in this day and age it would take 60 days to receive a 6 oz package.Good price on this though, so order well ahead of time if you use this often to avoid running out.

I build a lot of foreign car engines and this is one of my favorites when working on aluminum engines
