I have made several posts about this and here is the original
Tell me this isn't happening!!
I decided to try this fix and see what happens. I have outlined what I did as follows...
After deciding the most likely spot of where my oil weep was on the head, I decided to fix things with least intrusive repair possible. As I have mentioned, I can find no evidence the weeping is coming from the gasket. The spot with the arrow in the picture seems to have oil weeping through the RTV silicone I had put over it on an earlier occasion. When I touched my finger to that area, the RTV was spongy and there was oil on my finger from just that spot. Thus, I think it is coming from behind the area.
The first thing I did was remove the valve cover bolt at that location on the head. I ground a little over a 1/16 th of an inch off the end of the bolt. I thought it might be bottoming out making matters worse. When I gave that bolt an 1/8 th of a turn the weeping seemed to be worse in an earlier effort to isolate the leak. There was also oil at the bottom of the bolt hole which I removed before putting the bolt back in.
Next I ground a small area clean with my dremel and used a small dremel wire wheel to further clean things up. I tried not to get to carried away... and used disk brake cleaner to further clean the area. I then applied a two part mix and coat of JB Weld Quik Steel Epoxy to the area. Only a 300 degrees rating, but I wanted a more fluid sealer in the area first. After that set, I molded some Blue Magic Quik Steel Epoxy Putty over the area. It is suppose to be good to 500 degrees and impervious to chemicals. Lastly I smeared some Mac's Black RTV sealant over the patch area to blend and color match things. I found this spray can (see picture) of Design Engineering Hi-Temp Silicon Coating 1500 Degrees. After a test spray on a piece of pipe it appears to be a perfect color match with the low satin finish on the engine. Typical of what I see after washing and putting some Engine Brite on the engine. I'll mask things around the area and hit the repair spot with a little spray of the silicone coating for a finishing touch at a later date. Recommendations call for warmer temps.
I'll do a follow up as to the status of where I'm at after I have had a chance to do some riding. The weather is not great at the moment.
If I still have a weep spot, I guess I will have to rethink what I will do next and where I went wrong with this repair and the leak. I still do not think it's the gasket.
