Could this long term problem finally be fixed? Not convinced yet
I have a 92' Ford Ranger with remanufactured 2.9 V6
I have been hearing valve train rattling, ticking noises intermittently since I bought engine in June 2008. They have done 3 valve adjustments and lifter replacement. After the lifter replacement in Jan 2010 is when the valve train sounded the worst. It sounded like a diesel engine. Now I was hearing noises all the time. I complained.
The manufacturer said they would refund cost of engine and labor to remove engine and then I should get another rebuilt engine somewhere else. I said this wouldn’t work for me because it would not give me enough funds to pay for new engine and labor elsewhere. I have not communicated with them since.
I was just getting ready to file complaint and then the weird noises calmed down! I still hear a strange but brief noise occasionally. But it sounds much, much better. Engine is under warranty till June 2011. It seems to run ok for now.
Why did it take over a month for valve noise to go away? I know it only takes a short time for new lifters to pump up. I was thinking maybe the valve train issue was finally resolved. Other possibe causes of the noises were ruled out. But I can't help but think that the valve train has hidden damage that will recur like it always did in the past.
