Hey guys,
This is my first post on the forum. I did some searching first and can't find anyone who has had the problem I am having. We are stumped so I am going to describe it as best as I can: I have an 02 Ranger with the 4.0 SOHC. It has 137,000 miles on it and since I got it (about 3000 miles ago) it has made a rattle on startup. It would only last half a second till oil pressure built up, and everything pointed to timing chain tensioners. I was told that it's an easy fix; the springs wear out so all you have to do is put new tensioners in so I bought a set off a forum user who had extras. We put the rear one in first, Started up the engine and it still did the rattle for a second but seemed fine otherwise. Next we did the top one. Once we got it in, we started the truck and it rattled like crazy and the rattling did not go away. Pulled tensioner out to check it, looked fine, tried it again. Same thing. We did some research, Found out the tensioners need to be primed with oil first. Took both out, primed them, and reinstalled. Same thing , rattles continuously. So we thought we were sent bad tensioners. Bought brand new ones and primed them and put them in. We started it up and it rattled loud first, then got quiet. I was excited as the process of taking them out takes about an hour and we had now done it about 4 times. Took the truck for a ride and in less than and quarter mile it started rattling again. Extremely frustrating. At this point, we think there must be something we don't know about. A how to video found on YT made it seem like this would be quite simple. We are mechanically inclined but not extremely familiar with this engine. Based upon my explanation, did we do something wrong? I can't understand how this could have made my problem 100x worse instead of solving it. Thank for reading and Thank you for your help in advance.
