600hp was fun but boring. Going bigger!

Yeah I changed the oil. The plug was perfectly clean. I'm sure the pump is all that's wrong since I've been having issues getting oil to the top of the motor for a while now.

Well there's something you don't see every day. LOL Yep. New oil pump it is!

To be sure, I would put a mechanical gauge in a couple of test locations to quantify/confirm the pressure. From my experience, I dont trust the sender switch. IMO, just free revving the motor should not draw enough oil volume to cause that much pressure drop. Agreed, theres something else going on

vanderchevy18 · Jul 24, 2013

Hmm. OK so I installed the pressure gauge. It stays about 11-12psi idling. I replaced the lpop with a known good one and I noticed while it was off that there was a little grooving on the base plate. Nothing too catastrophic though I wouldn't think. Anyway, new pump, new oil pressure sensor, new oil, and still no go. 11-12psi idling and 30-40 revved up. As soon as the pump pressure gets below 15psi the factory gauge goes down and the light comes on. Weird

I'm assuming you changed filter when rules that out. I've had an oil cooler cause issues like this.

vanderchevy18 · Jul 24, 2013

Oil cooler huh? That would be a first for me.

vanderchevy18 · Jul 24, 2013

Something isn't right though. The stock pressure switch is set at 7psi. I'm getting 12 or so at the filter. There shouldn't be that big of a pressure drop.

vanderchevy18 · Jul 24, 2013

I'm wondering if it isn't my high pressure oil resivour gasket leaking down. I'm going to check the ICP too because it could also be the IPR stuck open causing a massive use of oil at idle. More than likely though its just that my front cover is scored too much. In that case I'm just SOL.

The pressure relief valve in the oil cooler in particular.. They can gum up and stick sometimes which can cause some strange oil pressure issues. In the older model coolers the valve likes to fall out completely because it is staked in place, not held in with a snap ring like the later model. All SD coolers will have the valve held in with a snap ring, so it's not usually a problem for y'all.

I have had a problem with old oil coolers as well!

vanderchevy18 · Jul 24, 2013

Oil cooler is fine. It's the front cover. It is very scored behind the oil pump gear. Very scored. So then. Here's the plan now. Park it for a few weeks until the chassis is done and I move into my new shop. Then drop the motor and trans into the race truck, spend some time finishing up the race truck, and be extremely surprised if it's done by the end of the race season. Unfortunately, that is my current position. I'll even toss on a bran new oil cooler when I move the engine over. The white truck will have a fresh stock motor dropped into it. Maybe even some stage 1's. Then I'm selling it. $10k. Anyone interested? It's famous. LOL LOL LOL

Dont stop at the front cover, be sure to pull rod and main caps for a visual at the bare minimum.

KBMKVIII · Jul 25, 2013

Sorry to hear vander. Have any pics of the inside of the pump and the cover you can load up?

vanderchevy18 · Jul 25, 2013

Nah. I didn't take any.

Strokersace · Jul 25, 2013

Phuck! Let's just change out the front covers, install your wg setup and go. Hell maybe I'll swing over one night soon and do it for you.

vanderchevy18 · Jul 25, 2013

Lol! Change out the front cover? Without removing the engine to remove the pan? Really? Can't wait to see that trick. LOL

Not really much of a trick to it. Lower the pan just enough to drop the oil pick up tube. Done it once in the past. Hell, I've changed a piston and rod in truck before. LOL It wasn't the best way to do it, but the guy needed the truck the next day and that's how he wanted it done.
