Thread: V8 wobbly crank pulley!

Need some advice!

Replaced timing cover to see if it would help oil pressure, which it did, marginally!
While I was at it, I changed the timing chain (must have been original) and gears. On assembly, once the engine was started the pulley was very wobbly!

The replacement crank gear looked very cheap and not up to the quality of the ordinal ......guess 12 quid for the kit was probably asking for trouble.
Put the pulley onto a lathe and seems to be true and wasn't a problem before.

Does this sound like a crank gear being the issue or not seated properly as the crank bolts up to it?
Any advice most appreciative.

Ah yes, forgot to mention there is about a mm play from the key way. I gather this is enough to make it wobble? A new balancer is in order then....bollocks! Will try and acquire one to try before pulling it all apart. Or can it be welded and new groove put in....won't do much for the balancing!
