What about the guys that have done the 6BT swap with the 4L80? I haven’t heard many complain.

Yes oil and filter were changed at the same time the injector was. Guess it was just too far gone. Strange but there was no symptom before it blew. No noise nothing till it let go. Maybe a 4bt as I understand the 6bt requires a body lift and other modifications

Well my question is answered. All was well and boom went the engine. Threw a rod. Now to figure what engine to put in or swap for a 12V

Will do. I will get it out and beat up on it right after I get my AC parts in. High of 82 today. You mentioned a valve set I’m not familiar with that procedure?

Ok update. I have compression checked the passenger side head of the block as I was still getting smoking out the tail pipe and an intermittent misfire. The pressures were measured starting at the passenger side front of the head nearest the fan: 500 320 450 480 The 320 psi has me concerned as...

I can cover it no worries there.

Tightened up, fired up and smoked out the neighborhood on the way out to the national forest. After about 10 minutes full throttle at varying intervals the majority of the smoke is gone. Still get a puff every once in a bit but much improved. Now onto my original problem of the AC system before...

Sounds like there is an intermittent misfire. I rechecked all the injectors and they are all working now where as before not so much.

Still has a sort of stumble almost like an intermittent missfire. It is very intermittent

Injector has been replaced. The smoking isn’t nearly as bad but it’s still there at idle and noticeable above idle but not as bad as before. Next I figure compression testing is in order. I am thinking maybe the stuck injector damaged that cylinder.

Yes I was getting a knocking noise. I plan on an oil change as well in short order.

I will get an injector on its way and go ahead and install new glow plugs. I will report back. Thank you all again for your help.

Yes it is the same cylinder. I will call around and probably order a new one just to have on hand. I’m a little north of Houston is you know of one that is reputable. Would you recommend pulling all 8 and having them rebuilt or just leave well enough and fiddle with the one? Wondering how many...

M Makes perfect sense. These injectors are a little different than the HEUI injection system I am familiar with. Would the leaking injector also explain why I had what looked like smoke coming out the loose intake gasket?

Alright found the wet glow plug. Can I make the assumption that injector is bad? Or could it still be a head problem? I appreciate the responses. I apologize if some of my questions seem redundant. When I log in sometimes y’all’s replies don’t show up until I post something.

Smoke did not stop when I cracked the line. I may very well have more issues with other injectors.

Of course I don’t have that tool yet. Good excuse to get one. Passenger side 2nd one from the front. Not the best spot. Any suggestions on a good source for the injectors. All the ones I find are for a turbo.

Alright I found one cylinder that makes the idle worse when it’s tight. When I loosen that injector the cylinder idle drops slightly but the idle overalll is better. There is also a knock I am getting from it but not consistently when the injector is snugged up. The knock definitely subsided...

I like yours it works. I have attached the video link 1st start of today 75 degrees out

Well correction. Which wire do I pull. There are two I see on the top of the pump?
