suddenly too rich

matzilla:
my curiosity was related to whether it would hold the vacuum  if the crank was turning in the seals.

maddoggy:
turning the crank should make no difference in a leakdown test unless the sealing surface on the crank is in bad shape or grooved.

tschisi:
I have got the same problem, but so bad that there is no way to start the engine.

Have a look at this:

Do you think the oil on the piston looks like a crank seal problem?

Arrgh.
Please save my day and say something like: "Replacing the seal takes about 5 minutes and the cases don?t have to be split."

tschisi:
Have to write again.
I had my top-end removed and my crank seals are ok.
My head gasket was leaky so i had water in the crankcase, but it was clear and free of oil.
But the engine won?t start, checked everything.

Hey T,
 There are five pages of troubleshooting (1st pg.)

 Is there anything else that changed other than doing a top end?
