The issue is with a �85 Toyota pickup. The engine went out one afternoon and we found a hole blasted through the motor by the oil pan. We arranged for a mechanic to replace the motor who said, after installation, he had trouble starting the vehicle. After I took possession of it, I also had trouble starting it and had it towed to the mechanic who sold me the motor. That mechanic said a failed oil pump had caused the new engine to seize and it is beyond repair and the warranty voided because of the oil pump failure. Is it not to be expected that a knowledgeable mechanic when installing the motor would have checked the oil pump? Should the hole and location of the damage to the original motor have clued the mechanic the oil pump should be inspected when the motor was replaced? Any thoughts would be appreciated. Also, I readily admit I�m out of my area of expertise here, so please, when responding feel free to dumb it down.

Hello,

Ok, the engine that was put in - was it a used one or Remanufactured?

If used the mechanic you took it too to install it should have been advised that it was a used engine and he should have recommended to replace a few items on the engine. So, unless you advised the mechanic then he most like wouldn't have recommended certian parts to be replaced.

Part I recommend being replaced on a used engine.

Oil Pump

Timing components

Water Pump

Rear Main Seal

Ok, now the person who sold you the engine should have also recommended parts that should be replaced. And since he sold you the engine he should have known something about the engine and if he didn't then he should have deffinately highly recommended changing parts listed above.

In my opinion both mechanics are at fault - the one who sold it to you should have given info on the engine since he was selling it. And the one who installed it should have asked questions about the engine so he could have made part replacement recommendations.

The engine was re-manufactured. It was the installer who located the engine for me, in fact. He and the seller are now trying to determine (as am I) which one was at fault.

It should be noted the truck was driven only once after I took possession of it. I took it to and from a transmission shop to have the system flushed. After that, at home, it failed to start and was towed to the seller's auto shop.

Ok, since it was a reman then it should be under warrantee. The seller can remove the oil pump and send it to the reman comp and have it checked to determine if it was defective part or if was do to improper oil level or something else.

Thanks for the quick response. If the reman company finds the pump bad, the oil level low will they still honor the warranty?

If they find that it was caused by low oil then the installer would be at fault and should replace engine at no cost.

If caused be defective pump seller should honor warrantee and replace engine.
