Dont forget using "momma's" good dish towel as a placemat and the bent fork and "butter knife" screwdriver...that was "borrowed" out of the china cabinet! I've been down that road and trust me it aint purty!

HAHA gotta love it! It will be a 3 page post by tomorrow LOL

I'm curious, and have my money on the lift pump...be sure and keep us updated!

Look at what I started we went from oil additive to balls floatin in the tub!

Gotta love the green glitter Roadway toggle switch extentions, I lucked out and bought a shi*load of NOS Roadway glitter shifter knobs...really gives a truck the old school look. I like that Brown west coast steering wheel, they are getting hard to come by!

Think I'm a gonna dump a little down the old detroit and see how she reacts...Lucas or no Lucas this up coming 2800 mile "venture" to Nevada in a 54 mile an hour ten wheeler with a set of 58's in the back...I might need a gallon along with my biscuits and gravy breakfast just to help my insides!!!

Any change in oil PSI? I would assume your runnin it the B model....If its runnin in yours should be ok in mine lol!

Lift / Transfer is the right term...and was on the tip of my tounge. Supply pump was close though I paid around $200.00 for mine plus core charge

Same here...MMM is all I have ever used in anything with a noisy valve train, dry knock etc etc...but thats coming from my old man, we are "old school" when it comes to these newer products. Kinda like motor honey I mean who in the hell would put that stuff in an engine, it takes 35 minutes for it just to pour out of the bottle its so thick!

Damn, that made my big toe hurt jus thinkin' bout that

The screamy meany from Detroit City is one thing, but my old 2 valve...she maybe no like it lol!

So....is this saying you run it in your truck? LOL! Immma little nervous to dump it in the Mack

LOL, its a tough one...I mean I dont think it could hurt...my trucks run good, they have minor blow by but great oil pressure and pleanty of balls. The Detroit 60 series in my White GMC is due for a service, maybe I'll slip some in and see how she reacts. The Mack is getting ready for a 2800 mile trek x country so I was thinking of adding some to her as well...I dunno

From the sound of it, its NOT the injector pump, but to go thru the pump (if you wanted it done) around $1000.00 to $1500.00 I just had one done. A new supply pump should only be a couple of hundred. If the truck runs good, but is losing prime after sitting I would put my money on the supply pump. There is a check valve on the return line that sometimes goes bad, but I would start with the pump. I pulled my hair out for 2 weeks trying to fiqure mine out, everyone told me its the lines, its this its that...I went with my gut instinct, replaced the supply pump and bingo she fired right up and never lost prime again.

When I say pump I dont mean the injector pump...I'm talking about the supply pump that mounts to the injector pump, should have 2 fuel lines going to it and possibly a primer.

Hmmmmmmm....I would have to say more than likely sounds like a bad supply pump, I had the same problem on a 94 RD tractor I had. I would start with the basics, check the fuel lines, replace the filters. But more than likely I would put money on it being the pump

Anyone running Lucas additive in there old 2 valves? I was at the parts place and they were trying to get me to buy a gallon of Lucas, I've know these guys for years and I dont think they would steer me wrong, but I was always told never to use any additive other than oil and thats coming from a veteran class A grease monkey (my old man) LOL! Any takes on this? I hear some pro's and cons on the stuff.....

When my grandfather passed in 2004, I carried his casket to the cemetary on the back of my flatbed Ford, the funeral director looked at me like I was crazy when I told him that this is what we wanted to do, I really didnt care what anyone thought to be honest. The man was involved in transportation industry for almost 40 years, and was the shop steward in the vehicle maintenance shop for Pan Am Airways for nearly 15 years prior to retirement. I followed his footsteps and became a Teamster. I remember I wore his Pan Am jacket as I drove that truck...it was a sad day, but I know as he looked down he would have been smiling ear to ear knowing that him and I were taking our last ride together. It really meant alot to me to be able to do that for him. When my time comes my wish would be to have an old Mack carry me to my final resting place...I never really was the Cadillac kind

Just wanted to say thanks to everyone who gave me advice with the frozen injectors, the truck is up and running and with the new pump she runs great! As for the sleeves that pulled out, I used a brass punch to put the new ones in, a little high temp RTV on the top and bottom (no reaming needed) and pleanty of never seize...I DONT WANT TO GO THRU THIS AGAIN LOL! Thanks again guys -Sean J. Kelly

Thats a good question, I would have to look at my tractor and see...and its snowin HARD so thats out for today. I would just play with it, back it off 1/4 and thats it and see what happens, If your going to replace the pin I wouldnt adjust it anymore than a 1/4 turn for now...wait until you have your new king pin then go from there.
