Hey guys, I am new here and was hoping one of you experts might be able to help me out. I have a 97 Ranger 4.0 with the OHV. It has been a great truck, overall miles are 280,000 but the engine was rebuilt about 120,000 miles ago. That being said, I found out i had one head with a crack right between the valves. (pretty common on these heads). So i ordered a new set, with new gaskets and put them on. I also decided to replace the cam synchronizer so i would not have to worry about it, but i had to replace the oil pump intermediate shaft at the same time because the old one was slightly worn (twisted) and would not go in the new synchronizer. Got everything back together and on the first start up it had a pretty clear clatter from what i was sure was the rocker arms/push rods. I made sure I put each one back in its original position during re assembly. So not taking any chances and wanting to get it fixed, I bought new rockers and pushrods and replaced those as well. The noise did not change. I have a fairly good understanding of engines and the more i have looked and listened im starting to think it is something else. It is not like a lifter noise, more of a constant clatter, similar to rockers. But I was under the truck today and the noise seemed to be even worse under the oil pan around where the oil pump is. I know i have oil pressure because i have checked it. I am honestly a little stumped on where to go. Any help or experience would be greatly appreciated. Other than the noise the truck runs pretty good, and the clatter does go up with the rpm.
Thanks a lot for any advice
