We have a 1990 Toyota RV but it is on the typcial Toyota Pickup chassie. We took it in to the Toyota dealer because we had a check engine light on and we had a significant loss of power going up hills. We were told that it was a knock sensor (computer error code 52) and that it needed to be replaced. Along with that work we were informed of at least 5 other issues including an exhaust manifold leak. So we agreed to have both the knock sensor and the exhaust manifold replaced for $2,091. When we went to pickup our rig we were told that unfortnuately the replacement of the knock sensor did not resolve the problem but in fact it was a wrist pin issue and we would now need to replace the engine. They said they could only hear the wrist pin once the exhuast manifold was replaced when they put the engine back together.
We have been told by other mechanics that they should have been able to hear the wrist pin or at least test to make sure that the knock sensor was indeed the problem. They have offered us $1000 labor refund good toward the installation of a rebuilt engine which will not cost us an additional $5,650 with the labor refund. However if we had known that we needed a new engine we never would have had the work done in the first place as we would like to repalce the engine with a 3.4L engine as opposed to the 3.0 which of course the dealer wont do. I am not comfortable with them working on our truck any more but would like to know that answers to the following questions:
- Could they have tested the knock sensor or determined that it was a wrist pin issue prior to doing the work?
- Do you think we should be refunded? If not another mechanic told us to take them to small claims court which sounds terrible but maybe that is our only option.
- Would you put a 3.4L engine in this rig which will give us much better power and overcome the head gasket issues that are common with the 3.0L engine or should we stick with a 3.0L engine.
I greatly appreciate your feedback as we are basically out $2000 with nothing to show for it which is appaling since we went to a dealership of all places.
Thanks for your help!!!
