Help! I have just changed my 2000 3.2L Rodeo's timing belt and the engine is running a little rough and noisy on acceleration.
I followed the instructions from my Haynes manual and checked the procedure against postings from this site. I thought all was well but when I accelerate there is "noise" from the air intake that has developed since the belt change. It sounds as if there is an air leak in the intake system but I have checked this and there is definitely no air leak.
The only thing that did not line up when I removed the original belt was the notch on the crank pulley with the mark on the oil pump (at 3:00 o'clock). The dotted line on the belt did line up with 9 o'clock on the crank pulley and the 2 solid lines on the belt did line up with the raised marks on the valve covers.
I made a reference mark with a permanent marker on the crank pulley and the engine to ensure it was in the same place when I put on the new belt.
All seemed to go well but I did have to rock the crank back and forth to get the teeth in the new belt to seat in the correct position while still maintaining the position of the crank (which I checked against the reference marks I made with the permanent marker).
All seemed to be correct and I put everything back together. Now the engine makes a guttural growl on acceleration which was not there before and seems to be a little under powered.
QUESTIONS: Could I have placed the new belt one notch off on the crank? If so would the engine run with the results I have described? Would the engine run AT ALL if I did put the new belt on one notch wrong on the crank?
BTW, the belt I replaced was the original Isuzu belt - The replacement was an OEM belt purchased from my local Isuzu dealer.
Please help!!!
Any advice or insight would be appreciated.
Thanks.....
