ok i just built a brand new gm 6.0 cast block lq9 and have very low oil pressure, pick up o ring is good the pump was good on my other motor.Im thinking since it was a new block i make be missing a oil plug in the block some where. Cause i had to put all of the water plugs in it. Does any one know if the are any oil plugs in the block? I put the little plastic one in the back but thats it. Thanks,Jason

There is also a hole in the front of the block in the same place the plastic one goes in the rear. Sometimes new blocks wont come with the plug installed. It looks like a small freeze plug.

Make sure that one is there as well.

Yea I just checked its not there. Do you know what size it is? Do you think autozone would have it?

Doubt it...call an LS vendor from this site like Texas speed or Thunder Racing

I believe you're looking for GM part number 9427693. We have them in stock or you can typically grab them at any decent GM parts house for a few bucks.

Curious, what oil pressure were you seeing?

Very low, it was about 10.

yeah, without that plug it would pretty much be zero.

I know because I know a guy who is a self perscribed LSx expert who built a motor once and failed to install that plug. Guess he doesnt know quite what he claims huh?

lol

Lol yea I can't belive I did that, I checked my bearing and they all look good.

no big deal. I can actually understand someone doing it. hell, I would have overlooked it the first time I built one of these motors.....but then again, I dont claim to be an expert or know it all.

glad you found it before any damage was done.
