100% in agreement with Matt! 👍 Check, not only static timing, but full mechanical advance (3,500 or so on a V-8)

There's a check weight in there, so pretty much the opposite. Engine has to be pulling enough vacuum to unseat it in order to draw from the valve cover. Does the PCV rattle if you shake it?

Customer sent me this on my way home Thursday......

I'm all about paying it forward! With the long spline pinion I've got now, that new yoke is surplus. This is a great forum and I'd like to be helpful if I can. Hopefully someone else with an '85-'92 2wd truck can make use of it! I think your gauge issue has to be the firewall connector or where the engine harness splits out near the ignition module. On the starter, be sure to check the transmission mode plug and the clutch interlock above your left foot. If either of these has come unplugged or the clutch safety is out of adjustment, the truck won't crank.

Technically, the breather (L, driver's side) should be sucking -at slight amount of -wind. This is your PCV at the rear of the RH valve cover being a metered vacuum leak, and clearing blow-by and oil mist/smoke from inside the engine. I'd imagine if your PCV still rattles and the hose to the flange is clear, you have enough blow-by that the PCV can't keep up.

Looking good! I know those drop center radiator supports are hard to find. Hope the weather cooperates with you Jonathan. Having that truck working will make things easier.

Torque is a force, power is force over time. Hence the 5,252 rpm factor for horsepower. The same holds for electricity. Voltage is potential but watts is work. Kilowatts means nothing but kilowatt hours is a measure of work done. That's why 1hp = 746W, but doesn't say anything about how efficient the motor is. It's just the power consumed. I went for a drive in a new customers Rivian R1-T last week. 0-60 in 2.4 seconds is mighty impressive for a 6,000+# vehicle. He wants me to install a sub panel and charger for it. Says he gets 400 on a charge if in economy mode, but that would be less at speed on a highway for lack of regen and air resistance.

Bradley, I hope you and yours are all safe! 🙏 Gary's daughter, my sister and Danny are all right around Charleston. I didn't really consider -where- you are in Georgia. So it looks like you are right between the powder blue (10.54) and deep violet (14.60) areas?

Congratulations! We all need more to do, and it seems you have a fun little project. I'd suggest you pull the drums and look for a broken spring. Hopefully the drum isn't gouged too bad. Since this in-tank lift pump is now working I'm not going to suggest the later FDM's, like Gary has done, eliminating the seemingly problematic reservoir/filter/high pressure rail mounted pump. It's funny how we always seem to get the same or similar troubles in bursts. "New to me" 5.0 fuel delivery problems in this case, but ductwork doors, hydraulic clutches, distributors. They all come in batches.....

This is the difference between a charger and a maintainer. 12.7 is JUST above the resting voltage for a 6 cell lead acid battery But you'll see up to 15V when charging. You don't want to keep that up because you'll create a lot of hydrogen gas, boil it dry and warp the plates.

You and Vivek need to get together and compare notes. If the oil is not on the ground, not getting sucked into the intake, and not being pushed into the radiator, there are very few options left

I believe we are talking about an '86 named Rufus, and why I used 460 instead of 7.5l Looking back the only Ford I've owned that was carbureted and designated in metric was my '85 5.0 HO GT, also with the 4180 and Duraspark

The 7.5L is Duraspark vs EEC so there is that to take into consideration. Which of these is actually applicable. I'm trying to find that 3rd pump in the schematic or EVTM. I have also concluded that splice numbers between the schematic and 1985 EVTM cannot be trusted You can see the EVTM calls this splice S-101 and the same splice on the schematic is S-211. So now it's just trying to piece together what I have of the old harness and match it to the documents as b st as possible I thought you were asking about the 5.0 with the fuel accumulator on the driver's rail. 460's never had a third pump, just in-tank, with the return vapor separator. Hot fuel changed from a selector relay to just using the switch, and as you noted, where the inertia switch is in the chain.

I am looking at my Haynes manual which has some schematics including later years and the EVTM. There may be a clue here: Later years and also 1985 5.0 had EEC control and circuit 37(yellow wire) power goes from the starter relay and then splices off before hitting the fuel pump cut off relay FIRST then the relay puts power to the Inertia switch. After the inertia switch power is spliced and sent to both the inline fuel pump and then the selector for front or rear fuel pumps. On the 7.5L for 1985 the relay and inertia switch are reversed. Power comes off the Starter relay (always hot) through the inertia switch then through splice S-110 then into the fuel pump cut off relay. Whatever that splice goes to is going to be always hot under normal conditions. Now comparing those to the chassis electrical schematics in my Haynes manual. The yellow wire off the the starter relay provides power to: EEC Peer Relay ECM Ignition Switch Haz/Stop light 20A fuse in the fuse box. So I believe it's going to be associated with one of those or the inline fuel pump. I am leaning towards the latter as it makes sense that it doesn't need to be part of the tank selector. It could be that it is putting power to the inline fuel pump as that is not shown here and correct me if I am wrong there have always been 3 electric pumps for this system in this configuration. Three pumps. The ECM will run the pumps for a few seconds and then it waits for PIP signal (distributor is turning)

We are safe, I didn't go to work today then about an hour after my shift starts I get an emergency alert saying everyone who lives west of Summerville along hwy 78, hwy 27 etc go home and stay home and if you are home shelter in place and don't leave. So good thing I didn't go. Jedburg road and everything from 78 to I26E including the east bound lanes of I26 are under 4 feet of water. Side note I am working on my harness now that the house is quiet again I am trying to find information on since S110. Is this just a service splice? I feel like there should be a third wire here and I don't know what 1985 schematic to find it in. That's the frustrating thing about the EVTM, it only shows the circuit in question. All the grounds are shown and labeled in the front. I wish the splices were too!

Can you pull the radiator and do it in situ? I'm no kind of expert with the 4.9-6 so I will leave that to others. But I definitely wouldn't butcher my throttle plate, because while it isn't a "big" cam the valve event timing is all wrong for what you want.

So that’s what the saying is! Janey looks at me and says “Dodo, you aren’t in Kansas anymore.” She's so cute! 🙂 Did you get swept up in a tornado with Dorothy and land on your head in an apple orchard???

Narrowing it down would be pulling the jumper shown in the first diagram and seeing if it's a really tarnished. I always like to apply Deoxit D5 and work the plug in and out, then give it a little flush with the same stuff.it works wonders on tuners and connectors.

Man, I didn't realize its size. Here (just North of Montreal), not windy but rain, rain, rain. Can't imagine how much water is up in the atmosphere and is falling down on East Coast right now! Tornado warnings in Oxford, where my brother is having his wedding tomorrow. I have my doubts that the tents will still be there! "Toto, we're not in Kansas anymore!"

C262 is the ignition side, not 32, the red/blue starter wire. You were sending power to the coil and ignition module.... You mentioned using a momentary switch to crank the starter. I'm saying that you wouldn't need to tap into any wiring if you used one of those piggyback fuseholders and ran your switch to above your left knee where the clutch safety is already jumpered.

It's okay, we all have these senior moments! It's my name, so I don't misplace stuff like that. And, I'm a bit of a geography geek. (though autism gives me a really weird filing system)

Debbie is pulling energy and moisture out of the gulf stream. You have to imagine how big this storm really is. It's crazy windy even up here in Connecticut!

You've got a hot cam with too much overlap. People like the sound of a choppy idle, but it makes throttle response like an on*-off switch. You have the stock cam. Put it back in, and the truck will be everything you want of it.

I'm surprised he doesn't have a high lift and entrenching tool bolted to the hood (so he can see them all the time ) and feel "manly"!!!

Are they on James Island or John's island? I'm confused... Waiting to hear from my sister. She really should be up here by now
