except he might have damaged sensor as he stated above. Try the simplest item first. That's why I recommended testing with a mechanical gauge..

Elsewise, he's on to your plan #2, which is your suggestion.

 

Alright... Here we go for today...LOL..

Well first off, I want to thank all you guys for helping me out here. Without this site I think that I might be screwed..LOL.. Anyways, I started the car when I got home from work this afternoon to check oil pressure again just to make sure before I tore it down AGAIN. Well I switched the gauges to the digital, it took about 1-2 seconds to read pressure but then SLOWLY raised. I could probably count to 30 faster than the pressure reached to 30PSI. I know its not supposed to be like that, so I went to the first and easiest thing.

I removed the intake, pulled the fuel pump fuse and unplugged the coils. Hooked a mechanical guage up. No oil pressure at all when cranking for 10-15 seconds. Well, obviously somethings wrong, so went ahead and did all the work to get the balancer off and all the other stuff. Finally got to the oil pump now. Removed the o-ring. Looked good(but you cant go by that), so we messed around with it, tryed a few different ways, and still no oil pressure. My dad was watching the oil pressure while I was turning the car over. There was no oil whatsoever getting slung around by the oil pump. I still have the timing cover off so the chain and pump are visible, which leads to my first question.

Should the pump sling oil everywhere when its being cranked over continually? The oil pump isnt even getting oil on itself. I would think that it should go everywhere but maybe not. Im not too familliar with the LSX setup.

This is basically where I left off for the night because I am stumped. I guess I could try a new oil pump but I would hate to buy the pump and it not be the problem. Let me know what you opinions are.

 

bump for previous post.. Maybe I can get more help!!!

 

I don't have any experience on a LS1 doing this yet, but from all I've read, I would check the pick-up tube and the O-ring at the pump.

They seem to be the two major items that cause the problem that you are having.

 

I already did that a few times. I am headed to the local chevy dealer right now to buy a new o-ring and oil pump. I guess that will eliminate those two things. If its not that, then the motor is comming out and its not going to go back in being a 346c.i.

I dont want to go there though b/c I dont have enough extra money at this time, so please, if you have any other suggestions, let me know

THANKS JASON

 

Well, I found the problem....

Messed with the car alot yesterday. Bought a new o-ring and oil pump but didnt even have to use the new pump. What I did was start with putting the new o-ring in. That didnt solve the problem at all. Tryed it a few times just to make sure. No luck. My dad had this bright idea to pull the check valve out. So we remove the check valve cover, pull the spring out, then remove the little cylinder. The cylinder had alot of sludge in it and it had some hard type of shavings in it that kinda scared me at first, but it ended up being(what seemes to be)lock tight that was on a bolt and came off at some point in the process maybe??? Either way, we completely cleaned the check valve off and re-installed the pump. Crank the car over and what do you know.. 31-33 PSI of oil pressure just on cranking it. Before it wouldnt even pull 1 PSI on a crank.

So, I start re-installing everything and finally get done around midnight last night. Finally able to start the car up now, haaaa 42-44 PSI and idle and 55+ PSI on a decent rev, just like before the cam install.

Guys I am sooooo happy that it wasnt something major at all. Sucks that I had to go through this, but maybe it'll help someone with their troubles one day. All I have to say is, make sure whenever any of you guys do a cam install, before you start putting everything back together, crank the car over and check for oil pressure. I didnt and I learned the hard way.

THANKS FOR ALL THE HELP AND THIS IS A GREAT WEBSITE... THANKS AGAIN

 

^ Glad you got it worked out. You should have taken some pictures and posted them to show everyone, so that they don't do the same thing.

 

Well, Add another guy to the list of those with a bad Oil Pressure sensor. Last night my guage pegged at 80psi. QUESTION: Since this is such a common problem, are we sure that GM hasn't issued one of those "undocumented" recalls....where if you complain, they fix it for free, but they don't publically advertise it????

 

Well, hopefully there is not a next time; however, you need not remove the intake to hook up a mechanical gauge. This can be accomplished by using the left front oil galley plug. Much easier.

 

Also, I would think it would be less risky and easier to pull the steering rack to access the front pulley than to lower the front saddle. The steering rack removal is easy. Glad you got it fixed and good job diagnosing the problem
