T/A with no oil pressure.

[IQ52]

So the owner has back surgery and cannot drive or shift the 4-speed for very long.

Yet he just has to go for a ride so he enlists a friend to finish driving when he gets tired.

The friend is so worried about driving a car as valuable as a T/A he spends most of his time watching gauges as he finishes the drive home. Wouldn't you know it, about 12 miles from home he say's, "I'm not kidding you, the oil pressure just dropped instantly while I was watching the gauge." He shut it off and coasted to a stop.

We pulled the filter and cut it open............full of bearing material. The engine is in the shop now, we'll see, we'll see.

The relief driver was right, the oil pressure dropped immediately. The bearing material seized the oil pump and broke the hex off the intermediate shaft. Instantly no oil pressure.

The exact same thing happened to me and my son in a '65 M'tang. He was at the wheel when the oil pressure gauge went to zero. I instantly turned the key off. Luckily we were only 1/8 mile from home. Pulled the oil pan and the oil pump shaft had broken. Installed a new oil pump shaft and oil pressure back to normal.

Too bad this fix won't be that easy.

Ouch!! My kind of luck

Dang, those bearings are terrible. How many miles did you have on them?

 

[Grady Cain]

Ugh... How does the crankshaft look?

Not my engine, customers engine. But I can guarantee, not many miles it that condition.

Beautiful, I think we'll run it as is.....................

I'll bet the pump rotors look good too.
That upper half of thrust bearing looks suspicious to me.

Now have another 1970 standard bore 340 block out getting align honed, decked and bored to +.030". There was a standard/standard forged crank setting in the corner with a coat of surface rust that we'll take to .010/.010. Ross forged pistons and Scat rods going in. We'll redo the previously ported heads with SS 11/32 stem 2.02/1.60 valves, design a custom solid flat tappet cam for it and use EDM face oiling solid lifters. Then too we'll use a billet timing timing chain set up and a Cloyes chain tensioner for a Magnum engine. I don't trust the old oil pickup after it passed all those bearing pieces up to the oil pump, so it will get a new Milodon pickup. Be very interesting to see what it dynos after the rebuild.

 

[IQ52]

Got all the parts in, new custom camshaft and everything. Going to pick up the block and balanced rotating assembly tomorrow. I'll get to share the results of the rebuild with everyone but the owner, he died 4 days ago. Damn.

 

[IQ52]

It has oil pressure now and 402 lb-ft @ 4,500 rpm & 411 HP @ 5,800 rpm.

 

[IRON MAN]

Congratulations! Be interested in knowing what rear wheel net hp is.

I lost all oil pressure when cruising in my 440. Turns out I burped a lifter when I took the engine to 6000 rpm. Synthetic oil probably saved the engine, and it ran well after replacing a few bent push rods.
