Did you check the intake with pressure or just with soapy water?

Georgia, no salt and the roads are in pretty good shape, so the suspension and what not isn't beat up too bad.

Intake, exhaust and brake lash. We had a 94 that had a weak Jake, adjusted all the valves and brake lash and it got a lot better. Still not great, but definitely better.

You can try to adjust the valves. Is it an actual Jacob's "Jake brake" or mack version "Jake break" of the time.

If you still have the bed PM me some pics and exact measurements and I might take it off your hands.

If I remember right, the top has basically a built in nut, just turn the bag assembly counter clockwise.

We just had a whole new system put in, but we are in georgia. All the hvac guys I talked to before the install said down to 30 degrees electric was good, but below that go with the duel fuel like eddeere. Where the lp/natural gas kicks in to help. We had 2 units installed 1.5 ton for upstairs and 4 ton for downstairs, both 14 seer units. The units and all new duct work came to $11,500.

You guys are the best! They are both mechanical engines, guess I should have added that earlier.

EM7 300 and E7 350

BMT to the rescue, I need the mack part numbers for pln injectors. One truck is a 94 with a 300, the other truck is a 94 with a 350. I dont want to take the old injectors out until I have the new ones ready to go in. Thank you all in advance.

4.42 rears and a 8ll will top out at about 77-78mph at 2000-2100 rpm. That's with 11r24.5 rubber.

The brake shoes are wore out and over-camming?

After linking that I realized it was done on an ai engine, not an ac engine. Not sure what you can do to an ac.

If possible, keep the studs soaked in penetrating fluid for a couple days before you try to remove the manifold.

The injectors, manifold, turbo. Can all be done in one day. If you have all of them available and on site. I would reset the valves while you are at it, and the valve cover is already off.
