Leaky Drain Bolt

poof_596 · 01-05-2008, 03:04 PM

My 2006 FZ6 has been to the yamaha dealer twice and it still leaks oil around the drain bolt. They have put new threads in the pan, a new bolt, and crush ring, and it still leaks. Any suggestions?

Is is cracked? You may have to replace the pan.

+1 on the crack possibility. May also be a porous casting.

if it is cracked look into getting it welded it should be cheaper that way

That's really strange.

It must be cracked, I would guess. If they are the only ones to have ever changed the oil, they should be the ones responsible for having it fixed.

That, or your drain bolt itself may be fucked up. If you got a dent on the bottom of the face, it won't put even pressure against the crush washer and could leak.

next time you drain the oil, inspect the pan for cracks or chips around the base of the oil pan where the ring meets the crankcase.

you can trace the leak by making sure everything is wiped down cleanly then put some trace powder where you suspect the leak is coming from and you will be able to see the oil leak by the powder getting darker.

I had a stubborn leak from a bolt on one of my engine covers. for some reason it would leak. so I used this, and it quit

I've actually used that before on my exhaust manifold on my truck. i bought one that has extra threaded holes for emissions equipment and had to plug them.

It SEALS really well, but i have not tried to remove anything that was installed with it.

Is it easy to take out bolts held in with that stuff?

yes. it has a little resistance but nothing like loctite or anything.

I'll try the sealant, the pan does not appear to be cracked or deformed in any way. So next time I do an oil change I will let you guys know how it turns out. Thanks

Wrap teflon tape around the bolt first. That's an easy cheap way to see if it's just sloppy threads. If it still leaks then move on to other fixes

check to see if they had to re-tap the pan and use a bigger plug.... check to see if it is crossthreaded..........if nothing else, then pick up a heli-coil, and do it yourself....having to change out the pan is a pain in the ass.

you don't want to use teflon tape. first of all it can't handle the heat. second it will tear when it's installed. it can end up inside the oil pan. that's why they make liquid thread sealants. teflon tape is meant for house plumbing.

I've used it in some pretty high heat environments on hydraulic hoses and never had a problem.
I know what you're saying though and it makes sense.
But, if you wrap the tape in the opposite direction of the threads it won't tear.

well that helps with installing it but if you have it down far enough on the threads it can come off inside the oil pan. on machinery or something I wouldn't care but when it comes to my bike or car I'll spend a few $ for something else.
