rocker box leak

[RichardL]

Anyone else happen to notice that removeing the rocker box is a lot easier than installing it? 

Anyway.. yeah, what I found might just be the cause of the leak. A lot worse than I expected, which was just a little fold-over of the gasket. The broken-off piece can be seen laying on top of the lifters.

G'day Richard.
Prick of a job ain't it. Would have been a lot worse if it was the exhaust side and blocked the drain hole!

In my experience the push-rod combs are often not quite right.  The locating slots for the studs are too narrow.  Its worth checking and taking a file to the comb to get it to sit right.

G'day Rob.
I have two combs. One for the A7 with std pushrods and the other modified one for the Cafe with tapered alloy pushrods that are fatter.

Not sure why you need copper Gaskets, if your mating surfaces are flat they will seal, when i firat assemble a engine the rocker boxes are flattened on plate glass with gringing past, steel heads are normally good but alloy ones often have the incerts pulled up and need flatteng, both alloy and steel heads can be surfaced if needed

i sorted mine a few years ago and now i notice a slight weep , nothing to write home about but maybe it's because she gets some stick.
