Anyone have opinions on the best oil pan sealers to use WITH a gasket? I bought this one minute gasket Right Stuff gray that some friend recommended, but I never heard of it. After reading the label it sounds to good to be true.

 

Urs is leaking?

 

That should work just fine. Grey is generally for higher torque applications, it is also more rigid(still kind of soft though) than black rtv once it has fully set.

On FC oil pans I have had good luck with using a gasket and a bead of black rtv on both sides.

 

i use honda-bond.. avil at a honda dealership but i kinda get it for free.. i assume its like 20 bucks a tube, never had any issues.

 

personally I've tried Black RTV and the Max Temp(or was it resist) thing and never gave me any problems.

 

Thanks for the inputs. I think I'll go with the black RTV.

 

honda bond works, mazda has some stuff too 8527-77-739 is the part number. black or grey silicon will also work.

the KEY IMPORTANT PART. is to make sure that the surfaces are clean, and that they get 24hours to dry/cure before it sees oil.

also you should throw out the gasket, it won't work as well as just silicon sealer.

 

I always use just the right stuff and never had a leak.

 

Just like j9fd3s, i dont use oil pan gaskets. Remove whatever u see and clean the area with acetone b4 u apply the sealant. Works 100% of the time and never leak

 

Hondabond is great stuff.

 

B)

 

we used the original mazda stuff, not a job you want to do more then once and leaks definitely suck

 

I ended up changing my mind and going with the Honda-bond. I never used it before, but I figured Honda-bond would be about as good as you can get. Everything I bought with Honda's name on it before last a long long time.

Why is it no good to use the gasket? I never had problems with gaskets on other parts of the engine.

 

mazda never used a gasket.

but the issue is with overtorquing the bolts, it has a tendency to rip the gasket at the holes which then causes leaks. the only reason to use a gasket is if the pan is warped from several rebuilds.

 

You're right! I looked and the original pan just has goop. Wow, I never noticed. I'll ditch the gasket then.

 

Looks like ill be doing the same thing lol

 

So two continuous beads on both sides of the block bolt holes ought to do it?

 

Not much point to doing it on the outside of the bolt holes, any that bypasses the first bead will leak around the bolts..

 

You're right. I put a single bead looping around the bolt holes towards inside the engine. It was a good thick bead. some squished out the bolt holes when i torqued it down. It should be a good seal.
