All of the oil pumps are the same LS1 or LS6 no difference..
..look like your oil pressure is right on now..but changing your stock push rod should be a priority for you..good luck .. Last edited by slt200mph; May 13, 2006 at 10:22 AM.

That was my understanding as well. And not only are the pumps different but there are two different style pickup tubes. One has a reciever groove, and one doesn't. The one with the groove needs the thicker O-ring, I think its a brown O-ring. The rest use the blue/green O-ring.
The oil pump on the LS 1 (97-04) and LS 6 (01-04) have the same part number..I work in a chevy dealer and looked it up on the computer just to confirm what I thought was the fact..

Not that I know of..I know that some people like to shim the oil pump spring for increased oil pressure..I have never had any problems with the stock pumps..I take em out the box and slap them on....They all seem to make the same pressure to me...a little over 40 at idle (45-50 lbs.)and a little over 60 (65-75 lbs.) at WFO ..

LS1 oil pump o-ring seal = 12557075
LS6 oil pump o-ring seal = 12557752
LS6 oil pump (replaces LS1 pump) = 12586666 (formerly 12586665, 12563964, 12556436)

GM did something similar with the exhaust manifold bolts. The new ones use a larger head and do not have the pointed tip to assist starting the threads. (A shittier bolt IMO lol) ....sorry for the tangent.
I am having the same problem. I recently installed 232/234 duration 595/598 lift with 918 springs, 7.4 pushrods, and comp lifters. Same knocking/ticking noise came from stock lifters with his cam. The noise only comes after car warms up, then it goes away. Anyone have any ideas?

thanks
thanks
the only problem i have now is... the entire reason i did this swap was b/c i was guzzling oil ... thought it was the vavle seals, so i was doing this all at once... however, i have all the new hardware in (of course) and the PCV blocked off right now, but i'm still blowing smoke out the tailpipes under WOT and high high rpms... when the compression was checked, it read 180 across teh board...
to add more info, the front two cylinders were teh two that had spark plugs caked in oil.... i have yet to pull the new plugs to see how they look, and i'm waiting to see if its still consuming oil, not just burning leftover ****....
however, if i'm still consuming oil, wtf could it be??
any other thoughts on what is making me consume so much oil... liek i said, i don't think its the PCV, considering its unhooked... car sucked 1/2 a quart in the past two days...
