Exterior "Gasket" Sealant? Looking to temporarily stop a leak


ktm

Recommended Posts

between the oil pan and block. I replaced the gasket already, but one of the PO's overtightened the pan and warped quite a few of the holes. In addition, the pan is slightly warped. I did not have the time to straighten it out, so I put on a new gasket and reinstalled the pan.

I will eventually repair the pan, but in the meantime is there a way to seal the exterior? I am thinking of using a silicone sealant where I spot the leak. Mind you it is a slight leak, but enough to make a mess of the garage floor (I have some cardboad down now).

My car had silicone all over the seam between pan and block when I bought it. Didn't stop the oil a bit. Silicone won't seal if you can't get all the oil cleaned off first. I dropped the pan on mine and fixed it properly.

You will have to pull the pan to fix it properly. Even if you were to put sealant around the outside of the gasket the oil will find it's way along the length of the gasket to the back side where there won't be any sealant and start leaking there.

I know I will have to fix the pan eventually. This is just a temporary measure to help cut down on the leak. Over at zcar.com they suggested Grey Sealant as it is oil resistant.

I am not losing that much oil (only leaks while the car is running and stops shortly after it is shutoff), but it does make a mess of the cross-member and suspension components that I just cleaned.
