anyone ever use sealent for water pump?
 

I am rebuilding an engine and dont have the gasket for the water pump. Has anyone ever used sealent for this and if so how did it turn out? Also missing the gasket for the oil filter...same question.


Thanks!

Malloy sells those gaskets and o-rings for the oil filter fairly cheap...probably less than $20...if you don't want to spend that much I have them used.

Get the gasket AND use a thin film of silicone.

So in your experiences the gaskets are an absolute necessity?

I wouldnt put it on there without it. Not on somthing that important. If that sealent gave up one day just cruising around.... You wouldnt even know it, and youd most likely over heat. Screw that. lll pay the extra 20 bucks and couple days wait.

on my FC.. it started crying from the wheeping hole.. so i changed the pump

using a chizel and some solvant i clean both surfaces really well

and then using only RTV reassembled it... It works fine..


many OEM cars don't even use Gaskets on the water pump

i've worked on an SR20 and RB26.. neither of which had a gasket..only RTV

I agree that while you CAN just use a good RTV sealant....it is best when used WITH a factory gasket.
If you have no choice, like you have to get your car going RIGHT now and can't wait a few days to get the gasket, you will PROBABLY be okay....but as others have said, why chance it? It IS kind of a pain in the ass to get to, and COULD fail unexpectedly....so why not do it right the first time?

The gasket for the water pump should be REALLY cheap - I'd go ahead and get it. Yes, I think you can get away without one, but you're fixin' to order some oil filter O-rings, so get it.

And, yes, the oil filter pedastal has 2 O-rings that seal it to the block. You can't use RTV here - this is a high pressure fitting, the O-ring are necessary to make it seal. Get the new O-rings, put a little vaseline on them, and install - that's it.

Both the o-rings and the gasket should be cheap, too.

i used the rvt on both sides of the new gasket. just dont apply too much. if you buy the pump from ray for i believe 67 bucks you get the gaskets encluded... yo might as well just do the pump while your at it.

turns out i had the oil filter o-rings after all. I am ordering a water pump gasket because we ended up having other blocking problems that make us unable to continue the project untill we order more parts. thanks for the responses.
