So just to preface this; 93 4.0 AT 138k. These noises were non existent before this “new stuff”. Hedman headers were installed last Thursday. Mechanic had to move the cats and exhaust a few inches to make the headers fit ( Y pipe was a huge pita). Along with the headers I replaced the plugs and...

Good evening friends. So over this last week I went camping at Lake Cachuma in central/southern CA with my Girlfriend, Daughter and buddy. If you're not familiar with the area, it is right past Santa Barbara, about 30 miles up east into the mountains, and it was 104 degrees the entire way. From...

I have a set of Hedman headers (89400) that I was really hoping to have installed while everything is apart for a head gasket job on my 93 4.0, but I don't have the Y pipe, just the left and right headers.. I've contacted Hedman and they only sell them with the full set. Are there any compatible...

So a few weekends ago my brother and I did the 95+ dual piston brake/knuckle swap to my 93. Everything went smoothly (we as smoothly as these things can go), and I successfully have the dual piston calipers with the 96 lines, rotors, bearings etc. After I got everything back in place and bled, I...

I had a quick question as to the legality of exhaust headers in California. I just obtained a set of Hedman headers (with the egr smog port) for my 93 4.0. I know the headers are legal, but with our smog restrictions any modifications to the intake system will cause a visual inspection fail.. so...

I'm doing the 97 dual piston new knuckle/rotor upgrade, for my 93 4.0 2wd, and I was probably going to replace the POS Duralast master cylinder with a motor craft one. My question is should I stick with a 93 master cylinder, or change it to the 97 master cylinder so it matches all the other...

I'm going to be doing the 1 to 2 piston brake swap soon, and I was just curious, should I buy a 1993 motorcraft master cylinder or a 1997 one that would be the same year as the breaks and other stuff? I currently have a pos AutoZone one I'm using and was just curious is the stock '93 was good...

So with my gauge when I fill it up (and I do stop when it clicks, I don't keep topping it {not saying it's never happened, but I don't try to do it}) it's about a quarter inch past full, and stays there a while, then will drop accordingly, but not like it should. Sometimes it will stay there...

Has anyone else recently tried browsing on their phone and had a pop up immediately take them to some spam page when opening a thread? I don't even have to click anything, just click a thread and after about 5 seconds it redirects me.. I literally can't even use this site with my mobile anymore..

Hey random question (no, this didn't happen to me or anything), if your driving on the freeway while running your A/C, and the A/C compressor seized up, would the pulley be seized , or would it still free spin? I was just thinking about it and wondering if it would burn through the belt in like...

So I need a new one..well really just the rubber gaskets that go around where it meets the MAF housing and throttle body. I've found it (part #F37Z9B659H) on eBay, but they want almost $80 for the whole assembly. I've already inquired about only purchasing the gaskets, but they only sell them...

I'd been having a never ending mystery issue with random misfire, CEL flashes, strange shifting, and bucking, almost always after a large bump, dip or turn. After replacing the normal list of junk (MAF, PCV, Coilpack, plugs etc etc) and the problem never went away Finally got traced down to the...

Looks like I have to drop the tank and/or remove the bed to get to the bottom of this Issue I'm having (Filler neck/tank seal? Post) , and bottom line what is the better option? thanks

So I've been having a mystery misfire/CEL that seems to affect everything (mpg, shifting, brakes seem worse, misfiring etc) and through the never-ending hunt to remedy this I've replaced the Coilpack, plugs, added DEI protect a boots (one cylinder has an excessive heat issue, the opposite...

While replacing my PCV (and grommet) I noticed that the old grommet deteriorated and some of the old crumbled rubber is down inside the crankcase. I can feel it, but can't seem to get any out.. is this something to worry about, or do I need to address this, and how Thanks

Does the small 45° hose that connects the line to the canister need to be any specific type of hose? I'm having a hard time finding the same hose and I was wondering if any other type would be fine to use?

I decided to post this in here, as the axle page didnt get any replies.. It's an easy install, but once I pop it out of its sealed motorcraft bag it's mine so... I recently replaced my OSS or VSS (or abs or whatever) with a crappy AutoZone one, and it's been almost a year, and my trucks acting...

UPDATE. I mistakenly have been calling it a VSS, when it is an OSS sensor. (not that anyone noticed or cared) I've searched and haven't found any previous posts about the difference between the smooth round sensor and the hexed flatish new one. It's an easy install, but once I pop it out of its...

Had a couple of questions that I wanted to ask you guys.. I have an oiled filter setup in my 93 4.0, and I was curious what the thoughts on filter wraps? Like does it reduce the flow the open filter creates (i like to think of them as high flow/less restrictive filters, since we know they aren't...
