Crankcase ventilation on military take out?

[teeth]

Hi guys,

I just replaced the original 6.5l in my 1997 Chevy Express 2500 (center mounted turbo style like Hummers) with a military take out from Teds trucks (these guys were absolutely great), but I am finding a few differences that have me a little puzzled.

1. My original 6.5 had a hole in the valve cover for the CDR valve, but the military engine does not. How did the military engines get around having this? I found HMMWV CDR valves on ebay that look different but I can't find where it would install..

2. Is this all the crankcase ventilation on these engines? If not, what else am I missing?

I will give Teds a call in the morning but I figured you guys would have a little insight for me incase they don't have a quick answer for me.

Thanks in advance!

You need to swap on the correct valve cover, one with the CDR vent on the correct bank (above cylinders 2,4,6,8).

Thanks John8662, but that is what I am trying to avoid (its pretty much ready to run, and in a van its no fun to take the covers off). I'm looking for what the military does in lieu of having a port in the valve cover, they don't just run it with nothing, right? And what about crankcase ventilation?

I just had the same issue with my Ted's engine. I just swapped the valve cover from my old engine.

If you don't want to go that way then I believe they used a different oil filler spout which had a port for the CDR valve.

Thanks AsphaltCowboy, that is exactly what I am looking for! Any pics from the back so I can see where it vents from?

Nevermind, just found out its on the intake horn. Thanks guys, I knew you guys would have this figured out.
