Jim's German Auto Informative - They treat you like an Idiot!!!
CORONA, CALIFORNIA -- After taking our BMW with a blown engine to Jim's German auto in Corona CA, we were not pleased with the replacement because of a sttrange noise coming from the time chain area especially when the engine was cold. We had already Told Jim to check the engine for this and he agreed that it was a strange noise that he had not heard and could not identify. However, Jim advised that we drive the car for 1000 miles and the noise would more than likely go away. If it didn't, he would replace the engine at no extra cost. Although the car ran well after the 1000 miles, the noise was still there and it seemed more pronounced. I took the car back to Jim for an evaluation and asked if the problem could be a faulty Oil pump and that I was concerned of a failure there. Jim became irate and asked "what does oil do?" to which I answered " it helps keep the engine cool". His retort was "and you call yourself a mechanic?" alluding to my experience as an Aircraft Mechanic. "If an oil pump fails the engine will immediately seize, just like that, no warning, the oil pump cant be failed, the engine is still running, you're not a mechanic! you don't understand anything about engines" he continued. And all this time I thought that oil was there to lubricate moving parts within an engine in order to minimize friction, which in turns creates HEAT, which in turn is the primary cause of failure in any internal combustion engine. I was schooled by Jim in how oil had nothing to do with keeping an engine cool. Hey, he calls himself a mechanic. He refused to look further at the car and as a result the noise is still there un-identified by this German Car expert. Next time, I will go to the real experts and see what they think oil does.
$6000.00 later it was the worst service I've ever had.
