    Would you pay $125 for this OEM intake box + tube?

    All the junkyards around me do not have the intake or they are charging over $125 for a set. I found this one for $125 + free shipping. Worth it? Looks kinda rough. Is there any decent after market intakes? I have yet to find an after market that looks good to me. 4.0l OHV Thank you

    Help with stalling

    Hey all, I am having problems with stalling out when putting it reverse and sometimes drive while the rpm’s are above 1k at idle. Mainly when it’s cold. When it’s slightly warmer up the rpm’s will drop and the engine will catch itself. Reverse does engage kinda harsh too. I replaced the...

    Anybody know what this is??

    Does anybody know what this is? Found in the bottom of my transmission pan. It's been slipping pretty bad lately so I figured I would drop the pan and check for metal shavings and replace the filter and fluid. This is what I found. Also, is that considered a lot of metal shavings? Trying to...

    1995 4.0 V6 swap to 5.0 V8?

    So I have this 95 Explorer Sport that I love dearly. I’ve done a few minor aesthetic mods to her here and there, nothing major and nothing to do with the engine. She runs perfectly, no issues at all since I replaced the clutch at 174k, and I just rolled over 179k. The thing is, I want a little...

    Ruff Idle on cold start. Almost Misfire. No codes

    2005 Sport Trac 4.0L has a ruff idle on a cold start up. It's almost sounding like a misfire. Engine also seems to idle too low after cold start. 400-500rpm and feels like its about to die. I can press on the gas a bit and it will get stuck at around 1000rpm for a min or 2, then it will idle...

    New here, but not new to Fords and wrenching on them. My son has an '06 Eddie Bauer with the 4.0. 174K miles. He bought it with a brand new transmission in it, and the motor seemingly ran well. After a while, he said it was rattling a lot. Doh. (Didn't listen to me when he bought it about...

    Should I rebuild the timing???

    I’m not sure what to do with my Explorer because of the timing chain rattle at startup. It’s an 07 4.0 advance trac, I just passed 160,000 miles and the start up rattle is progressively getting worse. It takes longer to go away especially on a cold day. The rest of the engine seems to be in good...
