Is what common?
For the crankshaft harmonic balancer seal to leak, it happens.
I put a one piece gasjet on it and its leaking between the snout of the timing cover and the seal. I think I'm going to have to loosen the water pump and timing cover and try to pull it down. Will I get water leaks if I dont remove and reseal those bolts?
Was the balancer grooved where the seal rides? There are "Speedy Sleeve" repair sleeves for them. Here's a Fel Pro #16201 for a small block Mopar.Fel-Pro-Harmonic-Balancer-Repair-Sleeve-Chevy-1955-94-Small.jpg
