Hi All,
When I got my bike about 18 months ago, I drained the oil in preparation of a change, but it was so black that I dropped the sump for an inspection. There was a bit of gunk in the bottom but for a 37 year old bike, which I suspect had never seen the sump removed it was not too bad at all. In the 150 odd miles I put on it before removing the sump, it never leaked in that area.
Since then I've gone through two of those OEM paper gaskets as it now leaks. Last replacement I even tried Permatex High Tack Red sealant, but to no avail. The oil seems to migrate past the gasket and is most evident on the bolt holes on the sides of the crankcase, where they go right through the crankcase flange.
I'm thinking of using a slightly thicker gasket material, but am wondering if this will cause any issues with the clearances, specifically the oil filter or the oil pick up galleries, as I would be moving the sump a smidge further away from the crankcase?
Any words of wisdom on this issue or other solutions?
Thanks in advance
