Oil filter cover threads stripped casing XT recommandation!

[xtrock]

Have a recommendation for everyone! Before threads go you wanna buy to bolts 6mm 90mm, cut off 3 threads and use it instead of original. They almost had room for 90mm but desided to just do 80mm long and you hold on to 1cm that wear out in time. Measure inside and you get excact mm, its not threads all the way in.
I read miss info here about dont do longer bolts its oil supply, no its not! The only bolt that have oil passage is lower and if you want block it its just for oil from filter draining when undo bolt. Infact you dont want oil from filter back into engine it can possible have material from engine there.
Remove top bolts, then open lower bolt a little så cover can be dropped down, clean out filter house, change filter. If you strip lower bolt you cant do longer, fill up with JB tap out again or do a insert thread then its still open as from fabric. Torque 10nm, new seal is good to have for correct pressure when torque up. I did the measuring on the XT 600 3TB and early 4PT same a little less than 2cm in. Measure others early models and its most likely same lenght in hole.
