Hello
I did not get that many responses to my inquiry about how a one
piece rear main seal is replaced on a late model 350 ci.
engine...So I contacted my neighbor that owns a rural repair shop up
the street that sponsors my race car to see if he knew how to do
it... He said it comes right out by prying with a blade
instrument like a screw driver without pulling the oil pan if the
clutch and flywheel assy are removed first. I told him that I had it
all apart in the garage and a rug below and would he inspect it and
do it for me... He said sure and came right down... After looking at
it for 10 seconds he asked for a screwdriver and while my son and I
watched he pried the seal out slick as butter... I know that I could
have done it but I couldn't find a photo or detail to show how it was
assembled so I didn't want to do it. Its easy! He said be careful
putting in the new one and to lubricate it and the crankshaft end
flange and to rotate the seal over the flange then sent it home into
the retainer. He said he would do it but I know now that I can...
I've put one similar to that into a SAAB!...The new seal came with a
gasket for the retainer but you will not need it if you don't take
the oil pan and the retainer off. My next problem was the pilot
bushing... It had an egg shaped hole in it and I knew it needed to be
replaced so I went to my garage friend and asked if he had a special
tool to remove it and sure enough he had a Snap On Bushing
remover...However when I tried to use it it seems the PO had cobbled
up the front of the bushing and I couldn't get the tool to grab the
front lip... I ended up drilling thru the edge of the bushing and
then inserted the tool and withdrew the damn thing...Now we have to
put it all back together but new parts are a wonderful thing to work
with. Good news at last and thanks I don't have to remove the pan.
