I've noticed a semi-loud metallic ticking from the passenger-side valve head. It's only loud or noticeable between 2200-3000rpm in any gear range.
Now just a couple days ago, I was riding on the highway for a solid 60 miles or so, and the noise got louder and more responsive to my accelerating.
I took my exit off the highway, and came to a stop at the traffic light. Now the metallic ticking noise is constant with idling, even though it wasn't before. I would assume this is valve related (top end), correct me if I'm wrong... I just don't know what to point the finger at i.e. rocker arm, valve guide, valve, connecting rod, lifter etc.
Can some one give me an idea as to what this symptom could be, and what it's gonna cost me to fix it, ball park. Thank you.
Up until now, it's been OK.
I believe that this is a 3.2 liter GM 6 cylinder. What you are hearing are dry valve lifters. If this is it, it will not damage the engine. If the oil is changed, it will probably go away for a few thousand miles but will reoccur over and over as the oil gets broken down. Welcome to the joys of Isuzu Rodeo ownership. I suffered with one for ten years and was ecstatic to replace it.
I love the truck, but the motor has some inherent flaws. Your valve tick is commonplace, and is one of the reasons I'm pulling the Isuzu motor out. Currently looking for a GM 60 degree V6 to replace it. Probably a 3.4 or 3.8 liter GM. This will bolt right in, but not sure about the electrics.
Looking for a 3.4 1st gen. push-rod style as I prefer carburetors over fuel injection. (yes I'm weird)
