MPJG Sump Gasket

[Roger Muir]

Has anyone experience of using silicone sealant instead of the cork gasket on the sump of the MPJG engine? Roger Muir Bromsgrove UK

Roger, not exactly, but tried the cork gasket and found it sqeezed out very easily and was not happy with that, then made my own thick card gasket from a good quality eastlight document folder, and fitted this with a light bead of orange hylomar/hermetite silicon sealant. No leaks since! Alan Webster TA 3239

The problem I have experienced with that is if you do a really good job in sealing it, you have one devil of a time taking the sump back off for whatever reason. It is really stuck together. Cheers Dean

Thanks for the replies regarding the use of silicone sealant. I understand the problem with it becoming'stuck!'. I had the same problem with the starter motor which I silicone sealed. However the cork sump gaskets I think tend to be unnecessarily thick or too soft. They do squeeze a great deal and you wonder how tight to take them up. The good thing about the MPJG block is that it is more or less one piece apart from the main bearing holders which by their nature have to be tight. The sump then becomes an integral part of the block once tightened. Also modern silicone sealants ahve good 'flex' properties. There I've just talked myself into using silicone!! Regards to all......

SILICONE UGH, one of the main problems with using silicone sealer in critical gasket areas is that you get "squiggles" of silicone on the inside where you can not remove, they usually wind up in the oil pump or the oil galleries causing the dreaded expensive sounds of "NO OIL PRESSURE", I like Permatex "High Tach" it comes in either a brush on or spray can, works well and no "squiggles" Joe

Joe and All- My other mechanical vice is vintage motorcycles. Recently, I was looking for a replacement sump plug for my Norton. Its a complex affair, a 1" outside thread with an inner cup with a filter screen- It look like a shot glass with threads on the outside. The screen is held in by a snap ring and the whole affair is allegedly the oil filter for the whole bike. Anyhow, I found 2 good used ones. As I disassembled them, I found the same things in each: Orange chunks of silcone and expensive pieces of ex-engine shards. I guess that how "just the filter plugs" came to be sold by themselves.

Mark I am sure that you did not pay the fellow anywhere near what it cost him for those plugs. Joe
