<VV> piston rings

[Eric Lucas]

Spence,

I suspect valve guides. I have seen this before with the worse condition at idle. Higher rpms tend to mask it as the inertia of the valve at higher speed helps mitigate the sealing. Also, you have good compression which further makes me want to look elsewhere. I don't think the style of valve seal is your problem. You could check the plugs and see which ones were fouled and might point you to one particular valve. If it was rings, you might rather expect fouling on all cylinders.
 
Hope that helps.

>The problem is the engine smokes. It's especially bad when the engine is hot and really bad if you let in idle for a while when it is hot. Compression is very good on all cylinders and there are no vacuum leaks. The smoke is the same with the vacuum modulator blocked off. It idles very well when cold, has good power and runs
