  I have a '33 Phaeton Deluxe and have an oil drip that I previously thought was coming from the dip stick outlet. After a closer look on the lift I have now discovered that it is coming from the lower pulley wheel at the of the fan belt at the engine block while running. Is this normal ? Is there a seal or gasket that needs to be replaced perhaps ?
I really appreciate all the feed back you other members provide. Thank You !

  Not normal and not unheard off. Originally there was a two-piece hard core asbestos seal surrounding the crankshaft pulley. Normally it proved to be effective, but with use wear on the shank of the pulley and on the seal halves would occur and eventually a leak could develop. It's something of a big job to replace the two halves of the seal (or replace it with a modern one-piece seal) as the timing gear cover needs to be removed and the oil pan dropped to access the existing seals and replace them. It's an even bigger job if the crank pulley requires replacement.

  Thank you
Would you know if the two asbestos seal halves are something readily available for purchase somewhere ?

  Typically the original seals ride on the steel crankshaft pulley. The seals wear into the steel causing the leak. To fix the pulley has to be removed and repaired and both halfs of the rope seal replaced. Half is in the front of the oil pan and half in the cover for the timing gear. You can get the rope seals, and oil pan gaskets from most aftermarket suppliers a kit is made by "Best Gasket Co"

  If your crankshaft pulley sealing surface is worn, you can take the pulley to a machine shop and have them press a new hardened steel sleeve onto it.

  Thank you
Parts ordered ????
I suppose the grill and radiator need to be removed to tackle this activity ?
