Thanks again. I have checked the pushrod tubes again, and they all move
easily under fairly light pressure (i.e. I can grab them between thumb and
forefinger and slide them out of the ends so they hang on the pushrods. I
thinks I need some Viton seals! The springs are in place, but maybe these
have lost some of their 'spring'. I wil try and get some new ones.

Also I cleaned all the upper engine area at the weekend - lots of old oil
and dust around there. I also removed the fan alternator, etc and cleaned in
the fan housing as much as possible. Fortunately, the rear (fan) seal looks
good (no fresh oil around) and there is no oil dripping from the bell
housing are (i.e. front (clutch) seal looks good). The main leaks are from
the oil cooler area, and both cylinder/head/tube areas, especially the right
(facing forwards). I am going to clean the underside when it stops snowing
in Calgary!!. Is it possible that oil is coming from the cylinder head
gasket? This is where it looks like. Can you check and re-torque the heads
with the engine in? I tried removing the upper tinware at the weekend, but
it was held fast by the engine surround seal. Is there a trick to removing
this? Do you need to remove the intake system from the heads? Is it just
going to be easier to get all the seals I need and then drop the engine to
do it? How high does the rear of the van need to be to clear the engine. I
was thinking of removing the intake system from the engine and leaving it
attached in the van. This way I wouldn't need to disconnect everything.

Sorry about all the questions

Thanks again

Michael
