Frozen Oil PumP?
Just installed a rebuilt 460 and a rebuilt transmission in my 77 f150. Here is the problem after only 1 week of driving, we started to have a car. back fire. After investigating we discovered the timing had change to 5 degrees when we had it set at 12. Why? Did this happen.
Next we tried to pull out the distrubutor and it seemed to be stuck. Took a crow bar to get it to pull free. WHY?
What would cause this.
We we finally did get it free, it seems to be fine. WE installed a new one but it seems to have a problem with one turn of the crank shaft being turned by hand you get 2 clicking noise. Could the oil pump rod be slipping inside the oil pan, or is the pump frozen and not turning at all. Any feed back on this would be very helpful as I have just had enough on this truck. Been working very weekend for 4 months on it. Thought I had it fix finally only to discover a all new problem. Thanks

A stuck Distributor seems odd in a newly rebuilt engine.As for the timing changing a jumped tooth on the timing chain will make the timing slow. Or if the distributor was not locked down good it can turn and retard the timing.This is unlikely with the distributor being stuck.Are you sure this engine is "rebuilt"?

o.k. bad news, just pulled out the new distrubutor and found that it is now missing some of it teeth. Not good, is my guess.
What does this mean? Not sure I want to hear the answer to that question.
As to the rebuilt engine, We were told it was rebuilt. We installed it our selves. We are at a total loss as to what the problem is here, need some major help.

Would not priming a new oil pump cause the pump to seize? I didn't prim the new pump when I installed the rebuilt engine, would that have caused the locking of the engine? Also if the cams are not damage, which I am checking on right now, How do I prime a new oil pump? Any suggestion on how to get the teeth from the distrubutor out of the engine area without damaging the engine. Thanks for the input.

not good news cam gear is damaged.
Now what.
if we take apart the motor to repair the cam can we get the metal fragments out.

Just a thought..., Cam retainer?
If the cam is walking you could get a clicking if one lifter started to ride on the adjacent lobe. The timing also won't stay put.
Sorry, but if it was rebuilt someone wasn't paying attention to the details. You shouldn't be having these kinds of problems on a fresh rebuild. Or even on one with a few miles. I have seen things get stuck in the oil pump (a broken hydraulic lifter snap ring, wire type) and the oil pump locked up. Looks like you'll be pulling the engine apart to find out what's going on. Pull the front cover to check the timing chain and cam retainer and if that's good pull the oil pan to check the oil pump.
Just my $.02

Priming the oil pump just pumps oil to all the bearings in the engine before starting it, preventing wear. The old distributor came out with it's gear intact; maybe the new one was the wrong one? If the cam is damaged, you will have to remove the front cover to replace it. Look at the cam retainer and timing chain. It worked for a week, something happened.

Just talk to the company that rebuilt the engine, and we have to take it out again but he was everything in tack to look things over. Will let you know what will come of it.

Frozen Oil PumP?
update on the truck, just got a call for the people (Blaine's motor) who rebuilt our engine, Apparently, a glob of grease was found in the oil pump which they are saying is the cause of it to lock up. And that it is our fault. Now how in the hell did it get there, that is my question, we did reuse our old screen off the old oil pump, as Blaine's provided us with a new oil pump. We soak the screen as well as the tube in gas, bushed it clean of all carbon build up, and thourghly soak and Blow out the old tube. I am telling you that what part we used was completely, clean and free of any foriegn objects.
What do you all thank, Are we being told a falsehood here? I find it hard to believe that one: a glob of grease was even there, and if it was, where in the hell did it come from. The engine, was rebuilt, the oil was new, the oil pump was new and there is no reason for grease to even have been anywhere near the engine. Could it be something else? Any ideas on this one? Colleen

I seem to remember something about using grease in a new pump. Forgot why, maybe to be sure it starts pumping. Any why, grease would not lock it up. It would have to be something hard to jam the gears.

Sounds to me like someone is trying to pass a used motor off as rebuilt. I would also say the timing chain Jumped causeing the Change and the Back Fire. A distributer does Not Get stuck that fast It would take a long long time to have stuck unless it was sittin in the rain. I would pull a spark plug and look and see if there is any hone marks A weeks worth of running there will still be hone marks and a used motor Would Most likely not even have a hint of hone marks.

Still waiting to see how much Blaine's is going to charge to but the engine back together again, but in the mean time I thought I would ask if any one knew why the shear pin on the distrubutor didn't break I would have thought that it was designed to break in order to save the cam from being destroyed as it was. Also what about the oil pump rod? I thought it too was designed to snap should the pump freeze up in order to prevent the distrubutor from distroying the cam.
Any ways just trying to figure what went wrong, I truely do not believe that our installation of the engine was the cause of the oil pump locking up.
More later when we have a conclusion to this mess.......

I was also wondering about the rool pin that holds the distributor gear on. I may do a test to see how much torque would be required to shear the same size pin. I think I once saw a pump drive shaft that had several twists in it.
