For the 1994-1995 L27 and L67 model years there were some issues with the valve stem seals and in some cases it was found to cause some spark knock as well as fouling out plugs...
We know its an issue on Brads car... But before its ever a real problem he'll be at 200K
But none the less this was an issue for the 94-95 L27'*.. 90-93 L27'* and L67'* did not suffer from this..

Losing about 1qt/1000mi
I'm losing about 1 quart per thousand miles if I keep the level high, but it tapers off as the level drops. Is that normal for these valve stem seals?
I just replaced plugs, no fouling found. MPG is 22-24. Maybe I don't need to worry about it?
Thanks for all the great pics and tips. You guys are on top of it!

Tools
To be clear:
The necessary tools are:
1. compressed air with fitting OR string/rope to hold valves up
2. spring compressor tool shown in clm2112'* picture
3. magnetic wand
4. tiny screwdriver
5. hemostats or needlenose pliers
6. Wrenches for valve covers
7. fine, lint free rags to cover oil passages
Also new gaskets
6 hours
at least 3 beers
Does that cover it?
