<VV> Top cover gaskets/loose screws

And it is remarkable just how problem free our engines are with all of the shrouding in place, properly sealed and with a clean engine (no blocked oil cooler or cylinder fins).

Clark, they were able to make the aluminum heads work on iron blocks
ecause the temp range was more steady and narrower on the water
umpers than we have on these air pumpers. Our engines had shrouding
round them to try to produce a more consistent temperature to help
itigate those issues, too. Mark Durham

nother reason screws loosen up is cover and block are aluminum and the
affle is steel.  They expand and contract at different rates causing the
asket surface to "walk" back and forth.  I never could understand how
luminum heads can work on an iron V8 block.  Lots of movement there!
aybe we should make an aluminum baffle plate.
