Well a tune from MadTuner is 150 with a core exchange. I'd get one asap! Trouble shooting will be much easier once you can rule out the tune issue.

I have a Madz28 mail order tune and it works pretty well. I suggest getting one till you can have it dyno tuned.

ok but did you guys have low oil pressure?

Only is its idling low should the oil pressure be any lower than it was before.

No, I installed valve train in a new crate LT1 engine. Oil pressue sits at 30 psi hot idle and 60 psi at WOT.

I have heard of a loosely fastened cam retaining plate causing lower oil pressure, but I don't know anything about it. What is your oil pressure at?

saylorZ28

iTrader: (6)

hot idle 5 to 10

Well GM spec is a min of 6-7 I think at hot idle. But if all you did was a cam swap, your oil pressure shouldn't have been adversely affected.

Are you sure you put the oil pump drive, located in the valley, back in correctly? Torqued to 13ft.lb?
Did you torque the cam retaining plate to 105 in.lb with a dab of thread locker on the bolts?
Did you drop the pan at all? Maybe a damaged pick up tube...

Can't think of what else can affect your oil pressure. I'd get a mechanical gauge on there.

yea just a cam swap. i did have the pan off to change the oil pan torqued everything back to spec.......

Sounds like your pick up tube might have fallen out. You could drain the oil, remove the plug or the oil level sensor and feel around to see if the pick up is laying on the bottom of the pan.

ok just put oil pressure gauge on and ran it to operating temp and it help steady at 20psi... pull valve covers and most all of my rocker are geting good oil coverage and some are barely getting oil should that be of concern..

ss.slp.ls1

20 psi hot idle is good. Don't know why some rockers have less oil. I'd say if you can see oil coming out of every pushrod, that's a good start. It doesn't need that much. Maybe try to pull out the pushrods and clean out the oil passages. I have no idea if that will help at all though.

ok but the tune is why it dont drive good right .. oh and i broke my sending unit does the ecu need the factory sending unit or will it be ok to run the other one ...i readjusted my rockers to and that seemed to help alot i have oil on all of them it ozes out of all of them and when you idle it up it seems to trow alot more on them but if something is wrong then i will find out down the road lol.... i found anther engine just in case 80k for 500 bucks ima buy it just in case

ss.slp.ls1

Without a tune, it depends, might be ok, might drive like ****. Like I said, get the tune asap. Just get any replacement sending unit.

drove it again and it had a oil pressure of around 7 to 10 hot idle .. im thinkin the mains are shot

redt/a2000

Mine was at 10psi at 30,000 mile and I was worried about the same issue so I rebuilt it with new crank and bearings, oil pump,etc. and no change in idle oil pressure. So I guess I just wasted my time, lol. I wouldn't worry to much about it. If you have a large cam chances are its idling lower and thats probably the issue.

I told you that 6-7 psi at hot idle is fine. As long as the pressure quickly increases as rpm does and you get ~ 10 psi for every 1000 rpm you're fine.

saylorZ28

iTrader: (6)

no i dont get that kind of pressure and it is slow to rise as rpms rise and on start up it takes a min to read .. plus i only get about 40 to 45 at high rpms
