It's actually pretty easy to do using the existing EGR system. I just stuffed a vacuum/pressure gauge on the upstream reference tube of the EGR and revved. Got 2-3 psi. I never understood referencing after the cat. Unless you have a significant blockage in the muffler, the pressure after the...

Mileage is 112k. Compression was perfect in May when it was checked. No coolant leaks. No vacuum leaks detectable and no other symptoms of vacuum leaks. I've already determined that it's not an A/C issue, I was just using that as an example so you knew what it felt like.

I did read through the thread. Most of the nut solutions in it won't fit behind my manual hubs. I took it apart yesterday. The keyways are intact, the pins are intact, but everything is loose. Almost as if the bearings wore out and allowed play. Just trying to figure out why three sets of...

Correct. On the driver's side, the retaining ring with the keyway and holes doesn't stay in place because it just gouged out the threads. Take a look at the thread I linked for pictures. I solved that issue temporarily by using an additional spacer between the bearing and inner nut. This...

Thanks for the link

Referencing this thread: Brake job gone wrong 94 B4000. Manual hubs from a 92. Quick synopsis of the above thread. Bought the truck with 80k on it a couple years ago. It developed a front bearing growl so I replaced them with Timken stuff. Drove it for a few months and took it for safety...

I will look into it. So far I've tried checking grounds and adding an additional one (jumper cables from the block to the battery) but no change. Tried whacking the EGR too in case it was coked up. No change, although that doesn't prove anything. The exhaust was recently off, so I have...

Help me dive into these codes before I start throwing parts at it. 94 Mazda B4000. Driving: Part throttle cruise is surging almost like a misfire but not rough-running. Almost as if you are cycling the AC compressor on and off rapidly or instantly going from 40-60% throttle about 5 times per...

94 B4000. Had to remove exhaust for a clutch job and (yay rust belt) busted the manifold flange bolts. Having trouble finding a driver's side manifold with EGR. Should I just go with headers? How bad are the $250 kits on Amazon or Ebay?

As much as I'd love a rack and pinion, 4x4 and twin I beam makes that no bueno. My current box is really sloppy, and judging by the binding I get, it has already been tightened... maybe too much. Looking for a good replacement. My experience with reman steering boxes has been awful. None of...

94 Mazda B4000 ext cab. Looking for good door trim panels. PW/PL/PMirrors. Mine have become brittle and most of the clips have broken off so they rattle. Prefer tan, but could dye them if you have gray. Important part is that they are in good condition. Only need driver's side, but if you...

Overkill, plus overkill, plus more overkill... I LOVE IT.

SOHC would be 75% of the work, but next to zero benefit. Same displacement, higher torque peak RPM. Modding an OHV is do-able, but kinda polishing a turd. You can port the heads to get quantity of flow, but they port design will never offer quality of flow. Anything I do (short of forced...

17 mpg empty, 11 towing 3500 lbs in the mountains. Runs great. Just slow. The percentage of time I spend towing is actually pretty high. In the non-summer time I'm often towing a 14' landscape trailer, but that is light and mostly around town. During the last two weeks I put about 1000...

Oh, and if I went 302, I'd do EFI. We do have a visual check for emissions here and I can't imagine sneaking a Qjet past an inspector without an extra $50 on the sly :)
