Oil weight and pressure relation - Page 2

Alvin questioned the pump all along, but like I said earlier, acquiring the pump we wanted was going to take a couple of weeks. It is now available and will be installed next week, or as soon as I get it.

Come on with the tags guys. Why the fuck would I go back there for something so simple?

Probably the oring. You said they dont drop the pan to change it so that leaves a lot of room for error.

With 100's of these installs with no issue, and $1000 labor savings, i still come out on top.

"Room for error." Sure. Likelihood of error, slim. But sure, could happen. And if it is, then they will take care of it. And I"ll still have $1000+ in my pocket.

We will all know the truth when I get it apart.

LMAO! Rep for you sir! That's a funny ass saying!

Just laughing at the saying,... not at you, Papa Bear! Hope you get it figured out.

If I remember correct the oil pump relief is only used during higher rpms bc the pump can't reach the relief pressure at idle or low rpms. If that's the case it's most likely not the pump itself

gearmesh, inc. · 08-17-2012, 02:33 PM

Thick oil on a cool morning tends to lift most oil pump reliefs, too. Once the oil warms up, the relief just dumps off excess pressure at higher rpm.

schardbody · 08-17-2012, 03:10 PM

Right GM casting oil pumps tend to have a problem with the relief sticking. Cold oil opens relief and never completely shuts.

Next time its fairly low shut it off for about 3 minutes and recrank, if president is now higher its the relief.

I'll give you 500 cash for the truck right now as is.

Since you paid someone to work on it, if its not right, take it back. i say o-ring as well. might as well put a hp/hv pump in at the same time.

My stock ls2 gets down to 20 with 5w-30, stock oil pump, and feeding twins.

How hot is the oil is key. 225 is good, 300 is hot.

I wouldn't reccommend a high volume pump on a tbss. With the way the sump is you could stand a good chance of running the pan dru

GreebeanZ28 · 08-17-2012, 05:31 PM

I'll take a cam bearing for 200 alex. LMAO. That tag is great!

ShawnBoyMoody · 08-17-2012, 05:37 PM

Lol thats great.
