Well, here are the results of the compression test. #1 - 120, #2 - 120, #3 - 105, #4 - 120. Not the best in the world. The #3 plug looks like it is more rich than the other three. However, I don't think I have burned valves. I say this, because all the valves are still within spec on the lash adjustment. I think a burned valve would be tight, and not still within adjustment (adjusted the valves about 10K ago). So I have weak compression, a rig with an unexplained fuel problem, and almost 313k on the odo. It might be time to throw in the towel. I am just not sure it is worth spending the money to fix the problems. I have found an entire intake assembly(throttle body to the head, with injectors) for $200 and for another $75, they will throw in the computer. I am not so sure that my rig is worth spending another $275 on it. Frankly, three years ago, I only paid $175 for it in the first place. I put a head gasket and tires on it, and the rest is 100k of history and good times. It really owes me nothing. I think I might just take off my new tires and pull my radio and battery, and call the scrap yard. It was a good run, but it might be over. But I have to say, even with a second engine at 180k, due to a head gakset failure, 313k is a testament to the durability of the little Isuzu. <img src="/forums/images/graemlins/cheers.gif" alt="" />
