I have rust on my camshafts........What shall i do??
91 Mazda 16 valve DOHC 4 Cyl. I recently found a car I bought new years ago. It was in a junkyard and I think the timing belt broke on them. It had broken once on me and no internal harm was done. Mazda proclaimed precision engineering. They put a new belt and left the cover off. I bought it, brought it home and pulled the valve cover. I turned the engine over once, not frozen, but found some fairly substantial rust on the (lobe parts) cams. From papers the previous owner left, it must've been parked since roughly July of '04. Suggestions? Other than get a new one.....

remove them and have them re-ground, unless your wanting a shade tree fix, in which case a scotchbrite pad, some wd40 and a couple hours of elbow grease

You may be able to drive it, but it will wear out very fast. I wouldn't trust to drive it very far. You will notice substantial power loss as time goes on. The engine doesn't have much time left if there is rust on the cams. Chances are that the cylinder walls may also be rusted along with many other internal parts.

If the rust left no deep pitting you should have no problem.
It's not a watch.

Put some good high detergent oil ... like mobile one... run it about 500 miles and change the oil.
