striped oil plug

Hello I'm new to this forum and i need some advice.

I bought my first bike KLR 650 08. I wanted to do my own maintenance. I changed oil and everthing went great unitl i striped out the oil plug. I had a heli-coil placed, by a mechanic not familar to bike mechanics, but does many spark plug repairs. He put it in on an angle. when tightened there is a gap about 2mm in length between the plug and the washer. (the washer is flush to the case but the bolt since it's on a angle never flushes to the washer) I'm leaking a couple cc's , maybe more when running hot. The bike shop refuses to put another heli-coil or tap new thread. Is there any way i can use a different washer perhaps brass or nylon that will compress and releive the gap... or any sealant i can use.

Thank you for any advice you have!

Not a good situation but a good machinest may be able to grind the high side down enough to allow the crimp ring to sit flush again. This is a repair that requires finding a qualified person with equipment to do the proceedure without removing the engine and splitting the case.

Agreed. In the mean time, wrap your bolt in teflon plumbers tape. The high heat kind. Any hardware store should have it. I stripped my bolt, too, and it is tapped out, but I still use it every time or I get a bit of seap. Just wrap around the part that goes in the threads, but be careful about getting any tape past the end of the drain threads.

Thumbs up Fiber or Rubber Washers

Or, you can go to a hardware store, Lowe's, Home Depot and purchase some fiber and/or rubber washers with an inside diameter that is the same as the diameter of the threaded part of the oil drain plug. Use quite a few to make a thickness so that the gap between the oil pan and the oil drain bolt/plug is completely filled. This will work until you can arrange a proper repair.

I would try a fiber or rubber washer before I hauled out the wallet and cleaned out the Benjamins.

And please add a little to your profile, like a general location. Marine shops have a wealth of goodies for sealing that dry landers never need. My first choices would be a Caterpillar Dealer or a John Deere Dealer. Both have tremendous inventories of O-rings and washers. And their parts people are pro's. They can adapt. Bring your plug with you and explain what you need to achieve. Pictures are worth a thousand words, and a good parts man ain't all that chatty.

This isn't the first time somebody got off a tad on a re-tap or a helicoil. There's a bike running around here that has been using a leather washer on the oil plug for about 6 years cuz somebody was in a hurry and kinda messed up..
