Hi all, Replacing the separator plate (1L5Z-7Z490-HA) and new blowoff valve upgrade (3L5Z-7M203-JA). I have the tsb instructions for the valve , but I am not clear on which parts to throw out. Step 6 says remove and discard the epc limit screen, epc limit valve (silver color) and spring (figure...

Hi all, been a while since I've been around, (put a mustang motor in my 98 explorer, rebuilt rear end etc. with a lot of help from this site). Now I have an issue with the 5r55e (code D) transmission. The o/d off light started flashing and it clunked as it went below 20mph while slowing down...

Replaced transfer case and the coasting rumble is gone, but the rear end is still whining mostly on light acceleration at speed. Need some help. -------------------------------------------------------------------------------- OK, I found the problem I think (or at least part of it). Here...

Hello, I just finished an engine swap with a long thread. I am moving this question to a new thread to preserve the swap thread as this is unrelated. My 98 4.0l SOHC 4wd makes a substantial whining, humming noise at certain combinations of road speed and engine load. Like decelerating down...

Hi All, I am in the final stages of my 98 4.0L SOHC engine swap. Just buttoning everything up and attaching the front accessories. I'm stuck because I forgot how the ground wires go. One of the first things I did when I pulled the motor, was disconnect the pcm and remove the hood. There are...

As some of you know, I am doing an engine swap in a 98 explorer in a seperate thread. This problem is not related to the swap so I am asking in a new thread. When I removed the starter, the nut holding the negative was rusted and I twisted off the heavy crimp on the end of the negative cable...

Any ideas how to get the motor mounts out? The top bolts are OK, but how do you get the lower one. It is on top of the differential on the drivers side. I can't even see it. RYDREW55

Engine swap 98 sohc with 05 Mustang motor Thanks again. (from original thread)http://www.explorerforum.com/forums/showthread.php?t=286471 Parts for the rebuild were expensive ($235 just for the crank) and I would still have a motor with 160k miles. I have decided to try and find a newer...

I'm starting a new thread, as I have decided to buy the 98 XLT with a broken harmonic balancer. Picking it up tonight. Before I decide to replace the engine, which I am fully prepared to do, how can I determine if the problem is a cracked crankshaft or just the harmonic balancer. As far as...

Hello all, I am new to this forum and new to explorers. I have been a long time member of many other car forums and do a lot of work on my cars. Question. Which model and year engines will fit a 98 xlt. I am a little confused if the sohc was an option to the ohv or the only v6 available in...
