Head gasket replacement?

[Quimrider]

:bang: I spoke too soon It's back to poooting again. I didn't see if the nut was loose again. It's not on the exhaust it looks like its on a stud in the cylinder head that goes thru a hole on the front of the cylinder jug.

I'm not close to my service manual.....or to my bike ....but on most that is the cam chain tensioner adjustment. There is a specific proceedure for adjusting it. If that is what it IS and it keeps coming loose......it could cause SERIOUS trouble.

OTOH, maybe in the process of tightening that, you bumped the pipes and they are just now settling back to their previoius position. If you do mess with the exhaust manifold bolts, be VERY careful; they tend to rust and are easy to break.

The cam chain tensioner is on the back left side of the cylinder jug. at first glance it just appears to be a stud in the cylinder head that secures thru a hole and with a nut to the cylinder jug. My car is out of commission right now so I'm not going to do anything with it for a while. :biggrin: I get to enjoy the lovely cool Ohio liquid sunshine on my way home from work today. <that was sarcasm in case you missed it>

Curious. They generally don't just drill extra holes so they can plug them with a bolt. It must have a function......or a potential function.

Maybe Alan, with all his vast mechanical experience, can tell us what it is! :skeptical: :biggrin:

Be glad to help:

If you don't know what it is, don't mess with it!

I know I'm in the minority here, but I prefer to spend my motorcycle time riding it rather than effing with it. I know I am gonna be screwed when I'm out in the middle of nowhere and get a flat or the flitzer-jammer pops out of the crustpump. I'll be sure to let you all know when that goes down so I can take my lumps. Hopefully I'll be in cell range and can have the wife come get me.

For those keeping track, so far I've:

1) Put gas in it.
2) Checked the air pressure.
3) Put air in it (more than once!)
4) Assembled 3/4ths of a windshield. Disassembled and re-packed same.
5) Located (and used!) the reserve switch.
6) Reset the trip odometer to zero.
7) Set the choke on (and back off!)
8) Tightened the nuts on the mirrors.
9) Looked at the brake fluid porthole. (Yep, there's fluid in there alright!)

Tonight maybe I will look into how to check the oil level. That one seems kind of important.

For the record, I had the head off my Peugeot moped back in the day and, although I can't say I knew exactly what I was doing, I cleaned up the cylinder, changed the spark plug, etc.

Plus, how many of you guys can do this?

Saaay, nice dove-tail!

DOH! there seems to be some misunderstanding about what I'm talking about. I'll take a picture when I find my camera. There is a stud and nut that helps to physically hold the cylinderhead to the cylinder jug together. The combustion gases that are leaking are doing so where the cylinderhead meets the cylinder jug which is where the head gasket is located. It is not leaking from a bolt or stud, granted both the stud i am talking about and said leak are close in proximity. It appears to be a minor issue at the moment. I'll tear down the engine and fix it later this winter.

Well, yea, that's kind of what tends to happen when you say "I tightened a bolt and the problem went away!!" :roll:

Sounds like you have a good handle on the problem now. No real need for pics.

I can but I'm not what I would call real good at it.

I've never seen dove tails in plywood before.

Probably will get a whistle blown here by the "off-topic" police, but I cheated a little with a router jig. I think it's 5/16" ply - I made 4 of these drawers for a media niche to hold CD's. Then they invented the ipod. It's also deep enough to hold DVD's. If this was a wood working site I'd post a few more pix, but I think I'm already pushing it. Suffice to say, it's some of the best results I've ever gotten with wood and power tools. I glued 'em, but there was really no need. Things went together like a puzzle and once assembled, could not be taken apart.
