I replaced my timing belt and tensioner piston in my '00 Rodeo LS 3.2L back in 2004, at 63k miles. Yay, beginner's luck, it worked!
Last week I got another belt, tensioner piston, and a water pump for the 120k mile maintenance. All are Isuzu OEM parts. However, this time around, I got so excited about getting to the water pump that I forgot to align the timing before removing the timing belt.
I did my best to re-align (according to Haynes manual). After re-assembly, and much finger-crossing, the engine starts but runs REAL rough, sounds like it's coughing, check engine light is flashing. It is running sort of like a badly balanced lawnmower engine. The whole engine shakes.
:roll:
So, I took it all back apart and tried re-aligning the timing again. Re-assembled, engine still runs REAL rough and sputters. Nonetheless, it runs and goes fairly high on RPM, although has little power.
There was some "resistance" turning the crankshaft with a wrench, and maybe not just compression stroke resistance.
I did manage to keep oil level and coolant level up after each change (water pump first, then double checked coolant situation on second re-alignment of timing belt).
Now, here's the deal and my questions:
1) The Haynes manual claims that the 3.2L is an interference engine! What gives? I see on the forum that consensus says it's NOT. This is a 2000 Rodeo LS 3.2L DOHC V6. Is it really non-interference?
2) Have I definitely bent/squashed/fracked/honked/@#
[email protected]% the valves?
3) If I have NOT necessarily damaged the valves/valvetrain, what else could I damage by having the timing off like this? Head lift from bad timing?
Again, the motor runs, but really rough. Hopefully I'm just out of phase on one bank or the other, and I can fix it!
Please advise... if you have some experience in this area. Thanks.
