Internal thread on head cover stripped? Oil leaking gs550es

No, not unless you want to kick open the door to a world of pain.
The cam bearings are line-bored and the cam caps are part of that matching set. To use one from another random head is asking for trouble.

I did it an have suffered no woe at all. No shame either

BTW while I am here, do you use the rubber valve cover gasket with RTV or without, I have used a light coat of black rtv in the past which makes gasket reuse almost impossible, I have a new gasket, is it designed to be used WITHOUT RTV?

good stuff very cery good stuff
cleans in alcohol delightfull source of joy and leakproofness.

This video shows the use of a mill to be sure to drill and tap straight. This is the critical element to assure a good job. No freehand work because the insert may wind up tilted in the workpiece.

See if you can get a local motorcycle shop to give a reference to a machinist. If it is a Suzuki dealer, they will probably have a guy that has done several if not hundreds.

Oh, and how did you strip it? I have been warned never to torque these to spec, rather just use a light hand.

I have no idea , I did not seem to over torque it, didn’t even know it was stripped until I had an oil leak after valve adjustment last weekend. I am going to try to find a machine shop
because I don’t have a drill press and I am sure I would drill it crooked.

I called 9 machine shops , no one here even does auto machining. Even called 3 different auto parts place, the place they used went out of business . Actually had a plumber at my house working and I asked him, he gave me the name of a diesel repair shop , I called them, they said they didn?t have an M7 helicoil , but if I brought them the part and the coil they would do it. So I?m without a ride until next week.

this kind of thing sometimes goes smoother if you show up in person with a 6 pack? just my experience

It's not "auto machining," it's installing a helicoil. Any machine shop can do it (if they want to that is.) Small jobs just don't pay enough to bother maybe? Anyway, don't give up.

Good for you. I take it you used plastigage or similarly made sure of the clearance, before just wanging on a random one?
