X2 on the Powermaster.

Which is probably what I should have done. But I was fighting mad at 3 reman. pumps' quality and decided to fix my old one.

"the pressure relief in the pump behind that large nut on the back of the pump," That valve was bad on 3 different reman. pumps I had. 2 from autozone, one from Napa. It was machined wrong at whatever facility did the reman. Burrs in the bore and the piston would stick. The orig. pump on my...

Sir, could you elaborate some on the "custom machined pre-cups"? That's a mod. I've never heard of before?

Ich "verstehe" dir nicht. I think that's right from my years working in Germany and never becoming fluent in the language. Not trying to be a prick.

I've got 7 acres and an MF 135 has served me well for many years. Plenty of power for plowing with a 2 bottom plow. Woods RM59 mower is big enough for a field finish mower. It's a '67 model, 42 HP Continental gas engine that I completely overhauled about 15 yrs. ago. Wet sleeve engine so...

"The pressure inside the line is not at injecting pressure. If it was, the injector would stay open, pouring fuel into the cylinder constantly. When the pump sends the pressure pulse, it will take a millisecond for that pressure wave to reach the injector tip. If the lines are not equal length...

Sir, do you remember the difference in lengths? How much it was?

? I believe that's wrong. The inj. lines on my DB2 seem to all be equal length. Otherwise, it would affect inj. timing.

That looks_exactly_like the Peninsular intercooler on my '93. I figure Mishimoto was their source.

Yeah, it's looking good. Is the intercooler from Peninsular, sir?

That would flat solve the problem with that actuator. The failure I've always seen with it is that you'll hear the popping noise for about 10 seconds after you shut off the truck. The other two actuators provide position feedback to the HVAC control head. They only run to their commanded...

If anyone ever has to remove the dash on GMT400, I would advise to replace the recirc. door actuator while you've got it out. _Extremely_hard part to change with the dash in. I saw a post on another forum where a guy changed it with the dash in, but I'mnot that limber anymore. That's the one...

Thanks very much, sir. Just what I needed to know.:happy:

Ok, now that I know the Suburban application, I'll start shopping around for the 11 CU R4. Thanks very much for the help, sir.

Thanks Will.

My son's truck is a 2000 K3500, 5.7 L. gas engine, 4L80E trans. We just had a new GM crate engine put in it and the guy that did the work told me it still had the stock eng. oil cooler lines retained with the metal clip at the engine. Neither of us had the time to change out the engine...

Thanks. Lots of knowledgeable folks here.:happy:

I had one of the variable orifice valves in my truck until the previous R4 compressor sh$t the bed. Blew trash all through the system, but I flushed it out real well and put on a new condensor. Easy to see why you can't flush a condensor anymore. They all seem to be parallel flow, not...

Y9u've paid your dues if the Dodge evaps are worse than my '93 Chevy.
