Brent,
your cam bearings may be chewing up as someone else suggested. Before you pull the camshaft from the engine, drain the
oil and/or take the
oil filter out and pour the contents out.
If the
oil and the filter have a lot of metal
flake, your cam bearings are wearing off.
The cam bearings have one hole which has to align with the oil hole in the block.
If this oil-hole is not aligned properly, because it was either badly installed or because has spun in its lodging, you are getting no oil to your camshaft bearings and they are running almost dry.
So go check your oil before you do anything else. Itīs like making a blood analisys before surgical intervention.
And by the way, cobra owners are masochists. No one would go through all the hassle when there are perfect cars out there with 5 year warranties.
But then, what sounds better than a Cobra in Tunnel ?????????????
Good luck, and donīt give up!!
