Sandwich Plate Bolt Size

spearfish25

I keep having a slight weeping leak from the sandwich plate. Mainly it happens after situations where the oil is very hot (thins out) or the pressure is high (cold starts in the winter). I'm just sick and tired of having a couple cc's of oil making a sheen on my undertray all the time. Mocal suggested removing the sandwich plate, cleaning all the surfaces, +/- using some black RTV on the sandwich plate O-ring, and possibly just swapping the O-ring for a new one. I'm starting at step one which is disassemble and clean. Not thrilled about using RTV and I'll replace the O-ring if I see a defect.

But I don't recall having the right socket for the extension bolt that comes with the sandwich plate. I'm hoping to torque it correctly in case that's part of the issue.

I recall it being something largish but I don't recall the exact size as I happened to have it on hand. I think it would be either 22mm or 24mm as I think that is as large as I have.

This is the first time we have ever heard of an issue with a sandwich plate leaking around the seal itself. I would lean towards the fitting not being torqued properly as well. Good luck!
