WTB trashed injectors for 6.2 and 6.5td

[joe bleaux]

The 6.2 uses the big pattern screw threads. It is in an n.a. van.

The 6.5 uses whatever came on it.

I want to try my hand at rebuilding so I can have spares.

Thanks

1982 6.2's used the unique thread injectors. 1983 and later are the same (threads) through the last 6.5's. The injector pop pressures and lengths were different, depending on engine and application. The injector length requires matching injector lines (do not bend to fit!).

Thanks for the info, Dmax. I assume that you are sure about that. This van had its engine replaced and I was almost sure that it is and '84/85. Now, I cracked the heads and found a pair with small cracks that were welded. I looked long and hard for these heads. In hindsight, I suppose I would have been better off just getting new injectors and used heads to utilize the newer style.

I always pay for my lessons, one way or another.

Yeah. I'm sure. If yours isn't original, all bets are off. Especially if you aren't sure what was installed. 1982 (OEM) was the only year to use coarse thread injectors, but the length and lines were the same as later years. Still the injector body length and lines are dependent on the vehicle they were in. The vans used short body injectors.

Rebuilding them is fine. As long as you are pop testing them, and using new nozzles, they'll be as good as remans you can buy (there's very little to a reman other than nozzles, springs/shims and time). Stay away from marine nozzles, as it will be very difficult to get a good spray pattern at 6.2L pressures and lower flow. OEM Bosch or Delphi are good nozzles, IIRC. John8662 is probably better at advising you on this than I.

Good deal then, Dmax.

I seem to recall something about N45 for these injectors.

I will look around for the parts.

Thanks

I have brand new Government Issue (Delphi) 6.2 injectors (meant for hummer) just collecting dust.

Delphi 6704001---6.2 Long fine thread

Make me a decent offer and they're yours...

[joe bleaux]

Coinball,

I don't think that they will fit in the heads on this engine.

I will check to be sure.

Thanks for the offer and I will get back with you.

I've got a fresh rebuilt set of coarse-thread heads if you are interested. I understand that you're looking for injectors and probably don't need any more odd-ball heads, but I though I'd offer them.

PM sent, Restoguy.
