I just changed my oil pump to a slp hi vol and it ran fine fore 20 miles or so and now it's at 10ps1. So I pulled the pump again that's good and the o ring is perfect. Any ideas?id like to drive the car before winter time but I have to figure this out

 

What oil are u using?

 

Did you used the right O ring?

 

Im using valvoline vr1 oil and i used the supplied black o- ring. Should i change the pump again to be safe cause I have another spare melling? Im stuck.

 

WHat is the weight of the oil?... Seems like the ls motors love the Mobil 1 10 w30..alot of members have switched to this oil and noticed their oil pressure increse .you could try that

 

im using vr1 and i used the supplied black o-ring that came with the pump.

 

the vr1 is 50 weight

 

Wow.. Have u always used that oil it's too thick...in ur case I oils switch to Mobil 1 10w 30...

 

I would think that 50 weight is WAY to thick

 

U double checked ur oil pump o ring so that checks out, Im thinking te weight of the oil is affecting it.. Another thing would be your oils pressure sending unit.. Think be bad or going out. It's like 30$ I'm sure at any auto parts

 

Silly iPhone ..... Changes my words ,excuse the words that don't seem to fit in lol

 

i already changed the sending unit and even hooked up a mechanical gauge to the oil pan on the drivers side and it read the same. Im going to put it back together and maybe move on to the barbell. Good idea or no?

 

50 weight is way to thick.

 

High volume?

How many quarts in your pan?

 

Did you only change the oil pump, or was there another reason you were that far into the engine?

 

the pan is the stock ls1 camaro pan, and i changed the oil pump because the last one froze on me.

 

98 car? I've seen the early design barbells get pushed out and cause an internal oil pressure leak, the heavier oil probably didn't help that out.

Another idea, did you change the oil after the pump replacement or more recently? I'm wondering if any debris caused further damage? Metal flakes in oil or stuck to a magnetic drain plug is usually a sign that worse things are happening. :-/

 

yup, its a 98 block in an 02 camaro. so should i check the barbell next?

 

I'd check that if the oil is clean with no metal.
