Oh poop

I'd pull the cams and then check free rotation before going after the head. You'll have to pull the carbs but you have to do that anyway.

Indeed, if removing the cams is a step in head removal, it's quite logical to test it in the method Nessism recommends. I totally understand the desire to rip into your engine, I had to have posplayr and a few others talk me out of a complete engine tear down to chase what's most likely a bum clutch hub. Breaking major engine seals (head gasket, case seals) seems to become quite expensive, rather quickly. That's money you could be spending on go-fast bits!

Chuck, I didn't even get that far as of yet. I've got to work within the limitation of my back and it's telling me to back off for a while. bending over kills me you know...

[chuck hahn]

you just give me the nod and i am in the truck and on my way. like i can head out right now!!!

[rustybronco]

Turtleface, It's no big deal to pull the head. 30 year old seals, possible valve damage and the lite coat of oil on the Number 2 & 3 pistons is telling me it's only a matter of time. (you pays me now or you pays me later kind of thing)

lot's of thing to consider.

Well... what d'ya find... huh... huh...

suspense is killing aint it?

Could also be the clutch basket nut came loose.

Rear tensioner?

My vote's for the rear tensioner blade coming adrift, possibly the source of the "carbon squishing" sound.

That's a good one. That could be why it did do a complete 360 a couple of times.

I haven't closely inspected the rear chain guide yet, but appears to be quite intact. forgoing the head removal, the only thing left to do is remove the exhaust camshaft.

[chuck hahn]

have ya done any more rooting around in the engine???

[rustybronco]

Yes I have. I just came in from removing the exhaust cam and we now have a free spinner.

I have yet to measure the chain stretch, or have took a good look at the chain guides, but I plan on doing that a little a little later on. the tensioner appears to work correctly, but I still will tear it down and check it. Tomorrow I plan on welding an air line fitting to a spark plug shell so that I can check the leak down in the cylinders. if all go well in that department, then I will forgo the head removal.

At the moment too many projects are eating up my time, but rest assured I get at it asap.

A small update...

"what I can see of the chain guide looks good"

http://www.alpha-sports.com/spst/1980%20GS850G/03.gif

it looks like the top half of the rear guide is missing. there is nothing remaining from where the tensioner contacts the guide on upwards.

the saga continues.

My vote's for the rear tensioner blade coming adrift, possibly the source of the "carbon squishing" sound.

Just might have a winner here...

[Guest]

Wellsuh!

I guess there might still be something said for hangin' out in the service dept when I was supposed to be behind the parts counter or on the
sales floor.

[rustybronco]

What's even better, is being a parts guy that has in the past wrenched for a living...
