  4. 3D Printed Rear Main Seal Installation Tool

    Just replaced the engine in my 07' ranger 4.0l. Replaced all timing components and all kinds of things.

    Does a custom cold air intake improve the sound of the engine?

    Hello everyone. I was thinking about purchasing a cold air intake for my 92 ford ranger 4.0L. I've always been skeptical as to how much a Cold air intake improves performance, but for a bit of extra sound quality, it would be worth it. Do any of you guys notice a sound difference with one...

    2000 4.0 Wiring Harness Help

    So If anyone viewing this has seen my other threads they relate to this. The previous owner cut back the old wiring harness but left five wires out, I’m wondering what they go to. Keep in mind he races trophy trucks and builds prerunners. I have an idea of what they go to but not entirely sure.

    So i pulled a 4.0l out of a 90 and grabbed the harness and ECU and believe i grabbed the map sensor since its speed density. What is the rest i need to convert and does my 89 have trans cooler or should i pull that from the donor truck as well, both are auto's and same transmission. So pretty...
  14. Transmission Gone CrAzY?!

    I recently had a new transmission put in my truck but the O/D OFF light still flashes. I have taken it back NUMEROUS times to have it checked because that usually means its over heated but everything checks out and reads fine.
