`52 engine oil leak??

[Summiitt]

Hi all,
Just getting the 80 sorted and Ive got a fairly decent oil leak from under the harmonic balance. Would it be a sump gasket or is it a seperate seal in the timing case?
Thanks in advance

Looking at my manual it could be either the timing case gasket, the sump gasket or the seal in the timing case that seals on the harmonic balancer. My guess is the seal.

Give the front of the motor a good degrease , check all the bolts are tight then run the motor & have a look. If it is the seal you may need to also fit a speedy sleeve to the harmonic balancer .
