Rocker cover stripped thread

[ram678]

I have a stripped thread in the lower front left rocker cover. I have searched this forum and found it is not an uncommon occcurance. I used a torque wrench but maybe it had been weakened before. My question is, what size is the bolt (mm) securing the rocker cover and what size (mm) Helicoil do I need? I am over in Kosovo working, so I want to make sure I order and get sent the right bit. Thanks.

Is it possible to just use a longer bolt?? Often the bolt supplied is not as long as the tapped hole is deep.

Thanks for the quick replies, I think I will go for the Helicoils as there are very good reports on them. It's not leaking at the moment, I have done about 2,000 miles since the last service a month ago and I am off to Sachsenring next weekend for the German MotoGP, another round trip of about 2,000 miles so I hope it holds out until I'm back from there. Thanks again.

timeserts are better for alloy , industry uses em more than timesert, especialy good for fine threads

just be careful,as i found out my bolt blow out from its thread at 90mph on the motorway didn't see all smoke from the oil pis?ing all over my foot and exhaust Nealy blow me engine up. and digger06 you are drilling into a steel insert anyway already done at the factory
