Motor is paid for. Gonna pick it up tomorrow and figure out where to squeeze this into my schedule. The good news since I did the swap last year, I have lots of extra parts and pieces and I should be able to dress the motor before I even pull the current engine.

We are gonna try again. This time with a rebuilt engine.

The blue o rings you can find some right sized o rings probably made of viton that will work. I can't imagine anyone who sells them specifically for the rack. Installing the rack and pinion assembly in these explorers is challenging enough. Using a used rack could be frustrating. As far as the...

I haven't had time to read this thread, But I do have 5.0 parts laying about the garage. What piece are we looking for?

Retail on Autozones website right now is 2301.99. I get it for a little less.

NuTech. Autozone sells their stuff. Yeah a longblock. Unfortunately id take too long if i did the rebuild. Would love it out on the road and not in my parking.

Well my daughter called me today and wants to get the EX back on the road. She is waiting on a tax return. With my Commercial account I can get a rebuilt 5.0 for $2200 with a 4 year warranty. And luckily now they have ready to go motors at the rebuilder. Which in October they did not. So I can...

Here in vegas. Just the machine work for the block, heads and rods is close to 2k. Machine cost is definitely way high.

Also for what it’s worth until the balancer failure. It ran great.

Ya know, when I rehabbed it originally when I started in 2021, if only i had replaced the balancer. It was one thing i left alone. And when it failed, im sure thats why the main bearings went bad. But should have would have could have. All that being said. Its still super clean, has basically...

Well I’d love to report an all is well message. However about August the “new” engine in the EX melted the number 3 piston ring, It blew the radiator in about a minute. It still runs. But can’t be driven. Ive had some personal stuff going on the later half of 2024 which has slowed me down. We...

Well 2024 has been a hell if a year for me. Hopefully you all are well, Merry Christmas! Happy new year as well!

Called the Ford dealer. They have the oil sender in stock. Going to get one today from there and see if I can get the dash gauge to work. My Daughter has to renew the registration then the EX can go back on the road. At this point I figure it needs to drive and if anything comes up I can deal...

Who among us has installed external gauges? Where have you happily mounted them?

I was going to do another cold start check today but at 8 am it was 91 degrees. That's above the 78 degrees the problems seem to happen around. hahaha!

Did a cold start this morning. Scanner shows coolant temp at 82 degrees. The EX started right away. I'd think that the vacuum leak I fixed had a small part in the rough cold starts. I need to make sure I have some type of working oil pressure gauge and send this vehicle out for daily use.

My son and I are building a 347 with AFR heads for our 1985 Capri RS. So I'm biased ;)

Just go with a 347 stroker with AFR heads!

OK. Got the EX passed smog test this morning. "Cold" starts have been good. Need to find a better oil pressure sender. Need yet another mechanical oil pressure gauge. I guess when they sit in the sun in the car they get wound up. The second one I installed now sits at 55 when the car is off...

Sounds like a ton of fun!

I was going to give an update last night but then i stumbled onto 410Fortunes 5.0 5speed Sport Trac thread! So I spent an hour reading that till i got tired. What a cool project! Now i want a 5 speed 5.0 explorer. Really cool stuff. Anyway yesterday i found a broken section of the vacuum supply...

So I went out just now and did the first start. It's about 79 degrees right now. The coolant temp is about 79 degrees. it started the first try, but it did stumble for a bit before it normalize itself. So this is interesting...

Ran the cylinder contribution test and there is no longer any misfires on 7. That's good! I also ran the idle control test and now I can get the idle real low during the test. Which is different than it was the other day. I think my mistake with the poor starting was not having the throttle...

Installed the cluster oil gauge. It's in the right position and it activates when the key is on. But it stays at zero. I think the oil sender isn't getting a good ground. As I have a couple adapters in there for the external oil pressure gauge too. So need to check that out.

Ok first start today. Coolant temp 82.5 degrees. 81 degrees outside. Started perfectly first try. Also replaced number 7 spark plug. When I pulled the boot off the brand new number 7 plug wire, the metal clip broke off the wire and stayed on the spark plug. SO I just swapped the other number 7...

I agree with you. I just saw your post. I did a bunch of stuff today. Going to re try the cold start test in the morning tomorrow. We shall see...

Ok, here is how today went. Work forced me into a junkyard run. So I grabbed some EX parts while I was there. I was lucky to find a 98 5.0 Mountaineer. So I grabbed a throttle body with the TPS, a new Oil pressure gauge from the cluster and some small stuff. I swapped the TB and bolted down the...

So I went out and did the first start of the day. I plugged in the scanner and it showed 75 degrees at the ECT. I grabbed a laser thermometer. The coolant in the radiator was 78 degree, everything else on the engine was 78-80 degrees. Outside temps at 845am 80 degrees. All seems normal. Did the...

For the record I did replace the temp sensor last year when I pulled the intake on the first motor. I reused the coolant tube that has the sensor in it for the PCM. I'll take a live data reading the next time I start it. And as you already know I changed the pump and filter and everything is the...

Question. Does anyone have an extra 5.0 throttle body they might want to sell? So I had a long work day today and I wasn't able to try anything on the EX at all. Yesterday I moved it from the street behind my gate on my property. Now I live in las Vegas and the outside temperature is suddenly...

Thanks guys. I do have the correct studded bolts there. But because I'm not quite done with everything i haven't bolted it down. The bracket is sitting on the studs. I'll get that done asap. Thanks for the info. That's what I was looking for.

I tried swapping a Duralast IACV in place of the Hitachi one that I currently have. The problem got worse. Started poorly, took several tries to get it to start and then it didn't really normalize the Idle. So I swapped the original back on and it was immediately better. Years ago I did a whole...

Ok, Here is what I did today. Replaced the fuel pump and fuel filter. Replaced the MAF. Swapped in a used rear O2 sensor. Swapping the o2 sensor fixed the P0141 code. The new fuel pump sounds better than the old one. Fuel filter was pretty clean. Did not get a load of black crap out of it. After...

Thanks for the tips guys! At least the pump is free and dropping the tank isn't too hard. And as we already know, there isn't much fuel in there right now. Once I get the pump in I'll retest pressure, then check everything again.

Model year is 1998 paint code is RC. Which I believe is medium Platinum metallic. My brother lives in Phoenix, so if you do find a nice tailgate dropping it there is fine. If your AC has no pressure and you aren't sure where to start. Replace the schrader valves and run a vacuum pump and see...

I put a fuel pressure gauge on the rail this morning. PSI went to 30 then started to decline. Once it starts it's running at 24psi. Someone correct me if I'm wrong but I believe Ford specs should have the fuel pump at 35psi when you key it on. I'm gonna try and drop the tank tomorrow and replace...

Been super busy this week. So since I first drove it I haven't been able to do much with it. But yesterday I cleaned the MAF and took it for a drive. That improved the spark knock but did not eliminate it. But I was able to drive it more aggressive than the first trip. The engine has good power...

No I didn't pull the heads. I did stick a bore scope in the spark plug holes and things looked clean. But steam cleaning couldn't hurt. I'll give that a go.

Alright, took the first drive tonight. Oil pressure is right where we want it. Coolant temps right where we want it. Transmission is silky smooth. 4 gears up, 4 gears down. The driveshaft with new U joints and a balance is silky smooth. A joy to drive. I'm going to re torque the exhaust manifold...

Sorry, I'm talking about the aftermarket gauge that has the probe in the thermostat housing.
