Brendan, I would say if you are going to pull the cylinders and change
the lower o-rings then putting in a new set of rings would be not much
extra work. If you want as close to OE as you can get then the Goetz
rings are the way to go. However they are not cheap. They usually run
around $75 for a set. The other options is a set of Grant rings. These
are made here in the USA and Grant has been making rings since around
the time of the model T Ford. These rings are much cheaper. They are
$39 for a set and the quality is very good. If you want to purchase a
set through us we would appreciate it. Right now I am out of the office
until Monday but I could get them out for you then if you wanted.
Usually I don't touch the lower o-ring, but since you had a problem
already with a pinched o-ring I would say it is a good idea. Then hone
the cylinder walls lightly while bathing them in ATF (Dexron). Clean
the pistons and ring grooves with a broken piece of old ring. When you
put the new rings on bathe the pistons and ring lands in oil so that
when you start the engine for the first time after doing this job
everything has some lube on it. I usually use 10-40 oil for a ring
break in. Run the van for 30 mins, be sure your coolant is bled and
your radiator fan is cycling on and off. Then drain the oil and change
the oil and filter. Run for another 500 miles and change the oil
again. One more time at a 1000 miles and then you should be good for
the 3000 mile oil change.
Send the heads out to a machine shop to have the valves checked and a
valve job completed. They will also clean the heads for you. Let me
know if you need any more information.
