Yep there are not many good 6.5s left. Time to start looking at the broken ones and welding them. At one time folks would not bother pre heating and welding cast engine blocks but they are becoming so scarce it has become a worthwhile venture to consider. It is also very doable if you have a...
Here is the bad news. Any Humvees will be scrapped at the end of service life except for the hundred or so SF97 ones the government released to the public some years back. Evenually all 1/4 million military trucks will be scrapped. They only made 10,775 civilian H1s and 1/3 of those are history...
Air bubble in the transfer pump?? This would mean air in the supply line somewhere. Either that or a piece of sediment blocking the screen in the IP inlet.
I have been lucky so far on my original 97 turbo 506 but i have low miles on mine at 130 kmiles now. Still runs like a top but i know one day i will post bad news here especialy given i drive 80mph plus at 3k plus rpm most of the time.
Yeah i know about all that but this is different. This would be using the stock ds4 without a pmd and a computer and replacing them with mechanical triggers. Aside from emmisions and bi directional comunication like OBD i think the truck could be run and timed/tuned without the stock computer...
Anyone ever come up with a manual control system for the DS4 pump and the 4l80e transmission effectively bypassing the computer?? Further more, anybody done it on the fly along with time setting?? Anyway thought i would ask!!
It hit me when i was fixing an automated audio mixing board today at...
Hey!! welcome!! Glad to see you signed up over here. I was going to ask about your head gasket question regarding the pin hole restrictions in the water flow. Someone here will have an answer for that.
No one else has said it so i will. Air in the fuel line or airlocked in the IP. In that regard check all hoses especially the one you had disconnected to change the IP and make sure all the air is bled out. Only take one little bubble to make a paperwieght!!
I have been asking over a the Hummer forum these same questions LOL. I can't find anyone running the pump. I did talk to Joe at Heath briefly yesterday and expressed my interest in purchasing at least some of the goodies in the kit, specificaly the Merlin and they appeared willing to take...
Gee i think a GM seal tab will fit right in there!! LOL
Anyway that sucks!! Wondering though if i cant be plugged up with brass. My uncle fixed a bullet hole on a Willis in WW2 that still runs. Different animal i suspect. If you remove the head, pan and unbolt the connecting rod and get the...
Much Better would be a servo type PWM motor controller that shares the frequency of output over dual transsitor chains and makes use of bipolar transistors as opposed to the darlington emitter type. This is a much larger package.
Neat idea with vac tubes. Maybe an old guitar amp would serve well. LOL
There is a bit going on inside the PMD beyonfd the 2 big power transistors. There a a few logic stages to deal with as the unit has a LM295 regulators, a CD401 flip flop, 3721 64M AF8L clock, S5230 PW1K nand plus a 14 pin...
Mine, an older rev 2 slightly modded has been on my IP going on 10 years without issue. Going through 5 is nuts and points to a potential IP fuel solenoid issue or as they say poppetitis!! Generaly caused by bad fuel agents contaminating the IP and siezing up the solenoid. P1216 P1217 are...
This was asked earlier in the thread,, don;t know if it was answered
J127 is equal to Oct 12 1997 casting date. I am assuming that number came off the rear passenger side of the block where the bell housing connects. In the Hummer world we call that an at risk block and has the cylinder 8 flaw...
