Also still have lower intake (GT40P), motor mounts/adapter plates, oil cooler, and other bits in the scrap pile not needed to swap this engine into a 60s car.

302/5.0 cast aluminum oil pan and pickup tube from a '97 Explorer 302. Might work for various Bronco II/Ranger swaps, not sure. Using this engine in a car so need a regular front sump pan. $100 + shipping? Not sure what they're worth but it's a nice pan if you can use it, make an offer.

Yes, we will keep the original '88 dash. A friend recently saw a Bronco II of the proper generation in the local junkyard. I was going to go get the engine bay harness or at least enough to make an adapter harness but it's gone now. I can always use the original harness from this truck but I...

What is the tapered rubber part that goes on the bottom of the injector? It looks like it sits against the lower intake and may lightly compress to keep the injector in place. I don't see it in any 4.0 or 302 parts listings for injecters or related orings, rebuild parts, etc. I thought it may...

Thanks. New oring looked slight thinner but definitely squeezed in a bit and is sealing.

On the oil pump drive. The seal on mine seems to be more of a square molded piece of plastic, like a bushing. It does not fit snug in the block, very loose and surely will leak. Maybe it's just a hardened oring. I got a FelPro 74061 distributor mounting oring for Ford V6 which lists...

Almost done rebuilding a 4.0 OHV. Does anyone make an oil pump priming tool for these? If not how do you prime the oil system? I'd rather not just crank with plugs out until it gets pressure. The oil pump driveshaft has goofy splined ends instead of a typical hex drive.

I bought the crank through RockAuto over 3 months ago on 10/3. They have a 30 day return policy but exempt any parts that have been installed. Enginetech has a 12 month warranty, details below. In my dealing with warranties in the past they are generally worthless. I'd imagine Enginetech will...

I picked up a new bolt today. It measures: M12 x 1.50 x 72mm My notes below... Threaded fully into crank (no balancer): 33mm thread left outside of crank 39mm threaded into crank Crank threads end ~38mm from face of snout Crank threads begin 10mm from face of snout First 10mm damaged...

The bolt came out chowdered at the last thread or two, and the first 20mm of thread in the crank was damaged. Well, the first 10mm of threads as I measured from the face of snout, and threads don't begin for 10mm from there. Threads end 38mm from the face. I was able to chase the threads with a...

I cleaned up the key with a file before installing, had a burr from removal. I will check installed height proud of the crank vs how deep the groove in the new balancer is. I did verify the key slid easily through the entire groove though. I've never had a balancer difficult to install before...

I am rebuilding a 4.0 OHV out of a '94 Ranger to swap into a Bronco II. Trying to install the balancer/damper on the crank and it does not want to fully seat. I initially installed the timing cover, lightly seated the bolts, and installed the dampener to center the seal, then tightened the...

Swapping an '88 Bronco II with 2.9 A4LD to 4.0 and M5OD/M5R1 out of a '94 Ranger. What clutch master cylinder, slave cylinder, and line do I need? Is the firewall pre-punched or otherwise marked for where the master should go like full size trucks are? Do I need to make a firewall reinforcement...

There was one of these mounts on the 4.0 I got from a '94 Ranger. Wasn't sure what it was. I'd sooner put a bolt with fender washers and a nylock through the motor mount just lightly installed to limit travel or keep the motor mount from separating entirely. I wouldn't think these engines make...

I acquired a copy of the Sven Pruett book. Some good information in there. unfortunately a good chunk of the performance stuff is products offered by companies that are no longer in business or no longer make the parts. Cleaned some parts today, rocker assemblies and disassembled one. Several...

Anyone make a flange to attach exhaust to either pattern? Seems a lot of work for every one of us to one off these flanges and oval pipes, for what should be a relatively easy to make piece.

Are the balancer bolts TTY one time use on these? Odd item to replace in most cases, I'd think.

Rebuilding a '94 4.0, my first time into one of these. I got a Melling high volume oil pump. Looking at the pump outlet and the block passage to the oil filter adapter there is a large difference in the size of these ports and the gasket is more square shaped around them. The oil pump has a much...

Never tig, mediocre at mig but could probably make it work if I had to. I don't want to spend that amount of time on this vehicle though. I'll have plenty of time into building the 4.0 and probably more into wiring. Prefer exhaust not be a big project. The handful available for the 4.0 mostly...

What headers will fit a 4.0 in a Bronco II? Specifically a '94 Ranger 4.0 into an '88 Bronco II, though I don't imagine that makes any difference.
