what type of sealant

[mtdripo]

Hello all,

While cleaning the inside of my valve cover the other day I noticed some of the sealant that covers all the seams as well as the screws on the removable metal peice (oil splash guard correct term?) on the inside of the valve cover had began to fall off in about 1/8th" sized chunks. This can't be good. I cleaned all of the remaining material off and removed the metal peice to clean behind it while the cover was off. Does anyone out there have any idea what this selant may be; it does not seem to be rtv due to the fact that it was hard and crumbly. Would high temp. rtv work for this? Any info is greatly appreciated.

If it was me, I'd use something like Permatex #2 rather than an RTV type of sealant.

Thanks for the advice, I think I've got some Permatex around here somewhere.

This is an old thread, I know, but it came in very handy for a repair that I had to do.... One of my cam covers suffered from deteriorating sealant as described, and I tried the fix that was suggested with Permatex #2. So far the results are excellent, but I will have to report back later on how it holds up under use.

Attached are some before, during and after pictures if you are interested.

Before the clean-up and fix. Note the missing screw (which may have contributed to the fact that I found the donor car in a boneyard).

During the clean-up (media blasted)

Then reassembled and sealed up with the Permatex #2 (messy, messy stuff during my experimentation of how to run a bead, but I figured it out!)

Thanks to all y'all who contribute your knowledge and make these things easier for the next person in need.

If interested in how the outside turned out, see the pictures in my gallery.
