I tried so hard not to break the oil pressure sending unit.....and broke it anyway. Not a bad idea to have a new one on hand in case. The brake booster hose goes to the back of the intake....the oil sender unit is below/in front of that and from what I understand what usually snags and breaks the sender. I'd try to pull that hose out of the brake booster and then rotate it up and out of the way if possible. Take your time and you should be okay. It's a snap once you get it out. Good luck and enjoy the new power!!

is the oil pressure sensor like a cylinder shaped sensor? it screws into the block at the rear of the intake if so i broke the damned thing...does anyone have a part number also, once you get the intake out i use the front new coolant line i bought and plug the back two correct?

Yep, you broke it. Here is a pic and a part number for an ac delco one. I ordered an extra when I did mine, but I disconnected the line at the booster, and it moved easily enough that it didn't break, so now I have this laying around.

also if my ls6 intake has the ridges ground off, do i need to change any of the coolant lines, and do i need to use the plugs for the rear coolant lines, or do i keep all the lines under the intake?

If the ridges are ground off, you can keep what you have on the car now. Some people change it over and don't want to do the grinding, some choose to save $$ and grind the ridges away. I chose the latter.

how much was the oil pressure sending sensor? i just wanna thank you man, i was really pissed when all this happened, now im feeling kinda confident when i hit it again tomorrow, when you did it was it a noticeable mod? and if so where did you notice the power down low or high in the powerband

It could be diff in your area, but since i work at a shop, i get the net price discount.

net= $28.63
list= $40.90

I felt it higher in the powerband, but I wasn't that impressed w/ the difference. Not that noticeable to me. Headers seemed better. Every bit helps though

remember, put the last 4 intake bolts on the back of the intake in before you put the intake under the cowl, otherwise, you won't get them in after......

Glad I could help. If you need any more help, let me know. I gotta go get some sleep or i will be dead at work tomorrow..

All said and done should take you about an hour with changing the sending unit.

awesome guys i am going to hit it hard after work tomorrow and see how it goes, i was hoping the gain would be noticeable, but alot of people are saying otherwise

night ghost

just make sure that u use ur stock bolts cause the ones u will get with the manifold are never as good and quite a bit weaker
i make that mistake and broke one in half but if u do break one and it is inthe hole just go to a a home depot or a lows and get something called like a reverse screw i think
