[TR] TR3A rear main seal w/ engine in

[bill beecher]

I would agree with Jerry, can be done, more work, awkward working position.  I just did one of these last year with good results but the motor was out.   I would recommend Kas K’s book if only for the chapter that covers this seal.

Art,
I suppose you could but it wouldn’t be easy and the results might disappoint. In that area in addition to the crank seal you must also carefully seal the rear bearing cap to block cavity. I have found that cavity is as much if not more of a leak path than the crank. The scroll type seal used on our cars is really quite good if set up properly by the work shop manual. But in my experience the cap to block seal cavity gets overlooked and I’ve seen significant leakage from a poor job with that area. Might be hard doing that from below. Many an engine rebuild has disappointed the owner because the cap to block is actually leaking but the crank seal gets the blame.
 
Just my 2 cents worth.

Can a vitron seal be installed while the engine is in place if the gearbox is out?
 
When I put the car up for winter storage I pulled the gearbox for a rebuild but I quickly realized most of the oil leakage was from the rear main crank seal.  However the winter storage area is gravel beside the garage without room to get an engine lift to the front (or maneuver it well on gravel).  Alternatively, I’d have to push the car up hill into the garage (all my car friends are distant and/or old).
 
Is it wishful thinking to contemplate pulling the pan and loosening the crank bolts to install the vitron upgraded seal from underneath?
 
Thanks,
 
Art
