what type of engine is this?
That'd be a diesel, probally a 6.2
If you've got a 700r4, it won't care if there is no vaccum, but I'm not sure how it'd affect the various emissions systems...

i dont care about emmissions. my ac does has been converted to a air pump. my auto hubs have been switched to warn. and i my cruz control dont work. is there any reason i cant just pull the vacuum pump out and cover the hole with a block off plate...
thanks for the help

Only problem is that if you just don't put vaccum onto the emissions systems, it may cause problems. Best way to find out is to just unhook the vac lines, and see if anything happens...

One question about the 6.2/6.5. Does the vacume pump run the oil pump? If so you will need to replace it with an adapter to turn the pump. I know some of them don't have pumps, so I'm sure that either the adaptors are readily availible or the pump doesn't drive the pump. Which is it?

that is what i am trying to find out. if anyone can help me out and let me know before this weekend i would be greatfull. the new vacuum pump is like 200 some dollars. i would much rather just remove it.
not sure...
I've never had my vacuum pump off the engine on my 6.2,(or any others)..so I am not certain if the vacuum pump drives the oil pump,or if its the oil pump that drives the vacuum pump!...I'd guess its the oil pump that drives the vacuum pump,since GM just blocked off the hole in the block with a freeze plug on motors that dont need a vacuum pump..but that is just a guess...it might have a "dummy" shaft in there if no vacuum pump is used??...
tRustyK5 and Colbystevens here have had their motors all torn down,and would probably know the answer to your question..but unless you can post up in the "Diesel" forum,they might not read your post here in the garage..maybe PM them??..

I looked in my GM truck service manual. The vacuum pump DOES drive the oil pump, just like the dizzy does in SBC's and BBC's. They do make an oil pump druve for apps without the vacuum pump. but I don't know what the part # is. Hope that helps
