Thanks Pdedse, all entered into the spreadsheet;

Just as a sidenote; my intakes had hardly moved and the exhaust had opened up some over 40.000 km. but i do take it easy.

In addition to that i actually glued my rubber gasket into the aluminum cover and the slight oil weep has stopped........

What did you use to glue it? I do have some sweating from the front outer corners of cylinders 1 and 4, got a brand new gasket but haven't mounted it just yet, waiting for the time to check the valve clearance

Hi Todd, i used "ados f2" which is a contact adhesive, honey color and also known as " bisonkit " in holland at the time, it is like syrup, i laid a consistent bead in the alu cover and put the gasket in.
Some expelled itself when i pushed the gasket home and i just wiped that up.
There were remnants of a contact adhesive on the rubber gasket as best as i could work out.
Put black silicone sealant in the CORNERS OF THE CHROME BUTTONS as described in the manual,placed the cover in it's place and tightened it up carefully.

As a substitute i could have used black silicone too but here we are.
Previously i put silicone sealant between the gasket and the cyl. head on the mating surfaces, that did nothing to stop the oil weeping, just in the wrong place, the seal works fine as it is provided.......... and i stopped tightening the bolts when they bottomed out, over time they will settle and "click" when unscrewed as usual, piece of cake to check for tightness of them if you feel uncertain.

Thanks! I have tried tightening the bolts, but somewhere just when I twisted the first one quarter of a turn I decided against it, have overtightened a bolt before. I'll look for the bisonkit, I also have a bunch of high temp sealants on hand, so I'll think about that

That sounds like a good idea,these are small threads on the bolts, easy to "scre--" them up, just forgot to mention i used a tube of adhesive, makes forming a bead easy.

Another sidenote; there is no need to take the spark plugs out and the way they sit in the cooling cavity it is very easy to drop some accumulated grit into the cylinder, once inside it can do some damage inside, just something to be aware of.

Do you mean I can remove the valve cover without removing the spark plugs? That's actually pretty neat because those spark plugs are so touchy and not very accessible

In a word; Yep.

Thank you very much, that's a very useful tip
