View Full Version : Porous engine cases

05-22-2010, 06:11 PM
HI All - I've been told there is product out there on the market which is great for fixing porous engine cases on early antique/veteran motorcycles.
I've been told it is a spray that is then oven cured.....
Anyone know of it?

Thanks - looks like it will do the job - do most people seal their inside cases?

Can't say what others do, but I seal mine. H-D sealed them during original production at least till the early 70's so it's most likely a good idea.

Harley used Gasoila for many years with good results. I've used it as well and like it, although I now prefer Glyptol (from Goodson).

Beware that Gasoila has no resistance to modern fuels whatsoever.

A leaky petcock on an OHV will curdle it into the oil upon sitting for any extended period of time.

It is not that there are not many fine products that have been used for generations,
it is just that modern fuels are extremely digestive from additives designed for fuel injectors, etc., etc.
