Oil filter cover bolts
Hi everyone! I have just done the second service on my 2003 XT 600e 4PT. The first time I did the service I noticed that the bolts holding the oil filter cover weak, ie as I tried to tighten them up I felt that melty feeling you get when a bolt/ or threads are about to strip. I left it a little looser than I would have liked, but after a while oil started to seep from the edge of the clutch cover. (Because the blots holding the oil filter cover are long and go right through and hold the clutch cover as well). These bolts are M6x80. I checked the depth, and there appeared to be a little extra depth in the hole, so I purchased some M6x90 bolts in the hopes that they would grab some fresh thread. It worked, with a washer or two  . But now I have done another service and it looks like the threads in the engine casing are gonna strip. I have found bits of thread left behind in the thread of the bolt. I understand about overtightening and this isnt what I did. It needs to be tighter than I can get it to keep the gaskets all sealed up! WTF. Is there something that can be done? My first thought was to get it all open, clutch cover and all, drill out the holes and re-thread them to M8 and get some M8x 90's and trim them a bit. Has anyone done anything like this?
