The oil light came on and I stopped. A little checking seems to indicate that the timing gears went. Either that or the cam broke. Anyway, it's a six stick. Is it much of as problem to change the timing gears with the engine in the truck? Looks like pulling the radiator will give me plenty of room. Been many years since I had to do something like this so any advice would be helpful. Thanks in advance. | | | | | Joined: Feb 2003 Posts: 452 Shop Shark | | Shop Shark Joined: Feb 2003 Posts: 452 | Wow! Sounds familiar... I had a Pinto throw a timing belt years ago. Took the bus, got some tools and parts and changed it on the side of the road. Not fun, but doable.
I would think removing the fan and damper should let you get the cover off and check things. I'd be worried about metal bits in the oil... and all through the engine. Might want to at least drop the pan and check for teeth if the gears went. If the cam broke, you may need to tear it down and clean it out.
Good luck!

A sheared cam gear or a cam broken ahead of the distributor gear will stall the engine instantly. If it was making a racket and still running, you've got a broken piston, broken connecting rod, or a rod bearing failure. It would also need to have a major bearing failure to lose enough oil presure to turn the idiot light on, or a broken oil pump drive. Drop the oil pan first, and look for broken stuff!

There's 2 bolts for the timing cover that go in from inside the pan (I know, crazy isn't it?) You'll be looking at removing the radiator and the grille at least to pull the cam. It's pressed, so a trip to the machine shop may be necessary. This is assuming it's just the gear and not a broken cam.
