MG MGA - Timing Chain cover

I have an ongoing leak here (big surprise I know)

I think the PO converted it to the MGB cover. Does an update of those seals necessitate pulling the engine? or can I manage with just pulling the radiator?
T McCarthy

Just pull the fan and the crankshaft pulley. The cover then comes off. If you still don't have enough room, then pull the radiator. The engine does not have to come out. As far as the cover is concerned, use a cover off of an early MGB engine (3 main bearing). The MGB seal is much better. This should solve your leak.

You may already be aware, but be sure to center the pulley hub in the seal before bolting the cover back down. Even a new seal may begin to leak fairly quickly if you're not somewhat careful with this.

Also check that the surface of the pulley mating to the seal is not pitted and acting like sandpaper. It must be smooth and shiny.

Prior to removing the cover I would check and see if it's the place of the actual leak. It can also be between the front plate and the block. Then you have to remove the timing gears along with the chain. It can all be done by removing the radiator.
Wash it down and dry it well. Then run it and observe closely. Dust in some talcomb powder and it will help locate the actual spot.
