Do all volks flywheels on a 72 1600 use an o ring gasket.  My flywheel has a groove in it for an o ring but no o ring was in it.  There was some oil on the bottom of the tranny where the clutch and flywheel is.  The rear main seal is good.  I put that in over a year ago but still leaked alittle.

Yes, i just did my rear main seal without the o-ring on the flywheel it will leak

Minivolks, you should just start a thread on engine building questions instead of starting a new thread for everything that pops up. It would save a lot of space on the forum pages. But yes, you need the o-ring or it'll leak like a sieve. How did your cylinders turn out or have you honed them yet?

Thats what  I figured about the o ring.   No I haven't honed them yet.

Where is a good place to purchase an o ring?  I have been searching on internet and everybody wants $9.00 to ship one o ring.  It will only need two stamps

If you have the engine apart you should really just buy a gasket set unless the gaskets on the motor are fairly new. Maybe someone here has a spare they could ship to you? You could also look in the yeelow pages for a bearing and seal supply shop. We have them in Canada called Bearing and Transmission, maybe you have something similar?

I think they come in the gasket set that most local parts stores sell.

Thought I ordered a clutch online from JCwhitney, but a pressure plate came in.  Cost me $25.00  Guess I'll keep it.  Talked to the online guy and he said they don't sell just the clutch.  Need to buy the whole kit.   Hum.    Looked in the catalog that came with the pressure plate,  Oh look,  a clutch.  Great salesman!!?   Any way, ordered a clutch from    It will be here in two days.  So almost back together.

So the o ring came in.  It is to big.  The relief in the inner section is thin and the o ring is thinker.  Even with that said, the o ring is bigger.  Are there different size flywheels?

It may look too big but try and fit it and you'll see it goes into the groove . there is only one size of oring unless you got one for a bus engine.

And lube, lube, lube to help it set in.

All back together, runs good.   But.  Any clues to why it doesn't start while hot.  I played with timing, nothin.  Checked spark from coil,  good.  Checked spark at plug, fine.  Just turns over sometimes slow, sometimes fast.  Sounds like it might catch, but nope.   When cold, fires right up.

Check your valve adjustment. That's the most common cause. Make sure your choke is all the way off.

Choke is electric.  Valves are set to .006.  The weather is cooler out right now.  It seems to starts better.  People say vapor lock.
