Well actually I donít stand on the gas that often. However I live in Houston and in a city like Houston there times when being able to accelerate quickly is the difference between living and dying.
I did change that stupid little bypass hose when I changed the water pump and I have to agree with you on that one. You really have to wonder what the engineers were thinking when they came up with that one. Be that as it may, after working on some fords and some chevys and some jeeps this truck is wonderfully uncomplicated and uncluttered.
No Iím pretty sure itís the timing chain because I hear it when itís accelerating. But like I said itís when I stand on it hard enough to make it shift down into passing gear. So actually in this state it is in a lower gear and running at a high RPM, at itís peak it really isnít under a heavy load, the strain is coming off and the parts are starting to float. This is where Iím hearing the slapping. Besides there is a distinct difference between the sound of spark knock and a timing chain slapping. Hey the engine has 118,000 miles on it so itís not surprising that the timing chain might be beginning to show a little stretch.
I got down the little Chiltonís book (these things are just next to useless) and read what it had to say, apparently Iím going to have to buy at least a couple of special tools, one of the ones they show looks like it may be kind of expensive. There was a time when you could go to the dealer and get the dealer service manual for any vehicle. After making some phone calls it looks like that may be a bit more involved, like having it special ordered.
