I had the motor in my sons 91 toyota pickup replaced secondary to a bad rod bearing. Anyway, I go to pick it up at the shop and notice no leaks under the vehicle.
My son and I take it for a quick drive then come back any pay........we're on our way. 24 miles from the shop I get a text, pull over it over heated. He was driving behind me so I pull over and make sure he is ok then head to the next exit so I can go back around and meet him on the freeway. We crawl up under the truck and the oil drain plug is gone, lots of oil under the truck and coolant all under the hood.
I called the shop and got it towed back over there that night; will work out the details the next day. The next morning my call to the shop was met with a surprise.t My radiator was bad and that led to the overheating. I said, "what about no oil in the truck".......... maybe, just maybe......no oil could lead to overheating.
I had one guy tell me the plug and the oil was there until I told him "I stuck my finger in the friggin hole last night on the side of the freeway". The plug.......and the oil suddenly reappeared today. Herein lies the problem; if the overheating is due to oil loss then they would be responsible for the damage to the engine. If it were the radiator, then it's my problem.
I just dropped $2400 on this motor.......you must be kidding me. It was implied that after it overheated......from "the radiator problem"; I got up under the truck and drained the oil right there along the freeway to put the blame on them. The mechanic stated there is "no way that plug can fall out". I hate to tell you but it can happen.
Google "oil drain plug falling out". It happens, it's a bolt and just like any other bolt, with vibration, is has potential to loosen. I'm just amazed they would accuse me of doing something as ridiculous as that. I must have taken it out with my teeth because I didn't have any tools.
We are still working on a resolution. Once the "bad radiator" has been replaced I'm gonna take it to a radiator shop for testing. I'd pretty much bet my left testicle that it will pressure test fine. I'm just hoping we don't have any damage on this new engine.
I'll post on the final shop resolution.
This was in Ranch Cordova, CA . I will keep the shop name anonymous at this time.
