Copper Washers - crankcase..

[schioler]

hey guys - i got alot of copperwashers and i wonder if i could use those
on all bolts when reassembling my crankcase or i should only use them for
the 4 bolt shat actual needs them?

I suppose you could use them all over, but there's no need to. And there are 6 spots that require them, not 4 .....

thanks man - should i add some lockthread to it - not the real strong red one but the
more soft one - its blue?

I don't think you need that. Just torque them properly. I would try to let the engine sit a day or two and check them all again in case some "settling in" has occurred. I would anti-seize all the threads too, don't assemble dry. For the 4 bolts across the top rear, that would include the entire bolt length, not just the threaded end.

i always anti-seize all bolts
thanks man for fast feedback
