[Healeys] 100 blown head gasket

[John Harper]

Mike

I can only think of one reason for removing the tappet cover and this is 
where one has too enthusiastically pulled out the push rods. The oil in 
the top of the tappet acts as a suction and the tappet can sometimes be 
pulled right out of the block. It is then almost impossible to put the 
tappet back in place without first removing the cover.

One thing that I do, but others might not agree, is to pull up the push 
rod about half an inch and then 'rattle' it around to make sure that the 
bottom end is free of the tappet.

Regards
