    HELP!!! TRUCK ONLY RUNS ON ALL 8 WITH VALVE COVER OFF

    Picture of the bottom side of the cover please. I am sure there will be a witness mark there some place.

    What is the max reliable overbore on a LMM block without filling the jackets?

    0.040" over is fine. Especially for the daily driver.

    Machine Down!

    Covers off the VF-3. Several issues all at once. Machine Down! High/Low Gear sensor flaking out. Might require removing the motor and transmission to get to the SOB since it is under the transmission, under the motor. Main Coolant line feeding the head has a big split in the Cat Trac. Wonder...

    Adding air to pickup for air trailer brakes.

    My trailer brake controller senses off the hydraulic brakes. Max indicated I have ever seen was less than 1400 PSI

    Adding air to pickup for air trailer brakes.

    Hydraulic line pressure is less than 2000 PSI.

    Adding air to pickup for air trailer brakes.

    Relay valves are instantaneous. Normally used on trailers to translate low volume signal air pressure to the brakes using the trailer's air tank. there are a few aimed at the hydraulic to air conversion. mico-inc-hydraulicoverair-relay-valves

    Adding air to pickup for air trailer brakes.

    Look for either Electric actuated or Hydraulic actuated relay valves. There are some ABS valves that can be used (with some tinkering) to provide proportional signal air using the electric brake controller. You will, of course, have to mimic essentially all of the normal air brake system. But...

    Piston rings not seating

    Is the backer spring installed on the bottom ring?

    The goal is to NOT bottom out the studs. That only puts additional stress on the threads in the block and does nothing to hold down the head. The whole thing about lube the nuts, with what and which washers to use goes away when you go to bolt stretch instead of torque.

    I think we are getting our wires crossed. Loc-Tite ONLY on the block side. It does NOTHING to affect torque other than keeping the stud from rotating.

    They won't, but if they do, use a stronger Loc-Tite!

    I know they are out there, but haven't looked. I have always made my own. Then again, I own a machine shop.......

    Never let loose on me, but I mark and check them afterwards to make sure. I am sure you could use the high strength Loc-Tite if you wanted.

    More consistent squeeze and there are no gaps when using seal rings. Wire always has a gap.

    I guess I do Studs differently that some/most of you. Clean holes. No oil. Blue Loc-Tite. Run them down and then back off at least 1/4 turn. Put an orientation mark on the top of the stud. All studs should be the same height. Put the head on and hand tighten all the nuts while making sure the...

    The air bubbles come from the head being the high spot in the system without a vent there to bleed them out. You have to vacuum purge to get rid of the bubbles. I see no real advantage on a Dmax. Ringing the block is traditional, and easier to some extent because you have the bore for...

    You can cut the o-rings in the heads. Just a 5 mil bump makes a hell of a difference. You can check the coolant flow balance, left and right, by measuring flow on the outlet side of each head. Don't even need to run the engine, just the pump. Cooling balance inside the head is a bit more...

    One of the Joys of aluminum heads is if you get them HOT, they will deform under the head studs. Then when they cool, the studs are loose. Solution comes from doing several things. Find out why the head is getting hot. Increase the clamping surface area for the stud. (bigger washers) Ensure...

    The LB7s with EGR were a complicated mess that never worked well.
