    Ceratec + LubeGard?

    Btw, extra oil didn't change anything substantially.

    possibly overtreated engine oil with LubeGard

    No change. So that assumption was not valid.

    Ceratec + LubeGard?

    Especially if there's an oil pickup problem. Thank you, I'm going with EP and LubeGard! Next up: what happens to startup pressure with an extra quart of oil. I can always drain it out.

    Ceratec + LubeGard?

    Thanks. The original plan was to use a decent oil + LubeGard, then once things were figured out (and corrected) a great oil + Ceratec, then back to something like LG or MoS2 + a great oil at the following regular OCI. It sounds like LubeGard would/might prevent Ceratec from doing it's thing...

    Ceratec + LubeGard?

    So here's some background. I've got a Hemi with a low oil pressure situation, and I want to protect it as best as possible - but I have to drive it a few times before it gets fixed. Kind of a rock vs hard place. The pressure is only a problem until the engine has warmed up, specifically when...

    possibly overtreated engine oil with LubeGard

    Quick update. I'm pretty convinced part of the problem is a compromised oil pickup tube. I'm going to put the 5w30 + Lube Gard back in, and add at least 1/2 additional quart, for a total of 7.5 quarts, and see if this impacts the startup pressure. Yep, I know it could/might/probably will foam up...

    possibly overtreated engine oil with LubeGard

    +1. What's interesting in this case, is that it is a rebuild engine with 35k/3 years on it. The pressure issue started 3k miles ago and gradually got worse (according to the PO). If the oring is in fact mechanically compromised, the only way I know that it would happen is due to a misalignment...

    possibly overtreated engine oil with LubeGard

    Btw loving the vehicle, even though the a/c blend doors' gears are non-functional (and stuck on hot, so it's turned off) which is a common problem. It has the air suspension which needed fixed via replacement front elbow fittings. It needs new shocks/struts (it is 10 years old & 206k on the...

    possibly overtreated engine oil with LubeGard

    I'll see if I can get another video of the o-ring area, once the front cover is off but before the pump is removed. What I have shows only one side. I'll post photos and/or a video clip. The one I have is around 280Mb, so I need to edit it down. This could simply be a case of a less careful oil...

    possibly overtreated engine oil with LubeGard

    Just a quick update. It looks like the o-ring is split, and the pickup tube doesn't seem to perfectly align into the oil pump. I'll see if I can get some excerpts from the borescoping effort and from the oil pump replacement. I'm not at all a fan of this integrated-into-pan pickup tube. In my...

    possibly overtreated engine oil with LubeGard

    I agree and my ears do too. Come to find out that the oil pickup tube is plastic as well, integrated into the oil pan (fixed in position), and there is no bolt in this application. Here's an example (note the tube sticks up and is fixed in place: https://www.ebay.com/itm/174955453777 I'm...

    possibly overtreated engine oil with LubeGard

    Hey folks, it looks like the oil pickup tube was not designed to function correctly with a missing bolt: https://www.jeepforum.com/threads/is-there-supposed-to-be-a-bolt-here-oil-pickup-tube.4465014/ /poorattemptathumor

    possibly overtreated engine oil with LubeGard

    Now that's great to hear :) I'm going to assume some worst case stuff with my particular situation: the oil pressure is low because of excessive bearing clearances (cheap crate engine), and the cam is already getting scored because at least one lifter is no longer rolling. What I'll try to do...

    possibly overtreated engine oil with LubeGard

    Yeah, I too thought earlier there might be a design issue. I'm way still in the learning mode for sure. I ran across a great analysis by someone, saying that in a nutshell if there was an actual design issue, most/close to all of the engines would be failing. That's definitely not the case. I...

    possibly overtreated engine oil with LubeGard

    Just a few quick notes: ECO light comes on now that the ECM codes are clear. No funky driving issues or noises. I'm manually keeping the idle speed high while I warm it up. I'll do a detailed analysis now that there's fresh oil in there. First up is testing the sensor of course. Next is...

    possibly overtreated engine oil with LubeGard

    It's at 7 quarts (6 oil, 1 LG) so in this particular respect, I'm gtg. I'll check it with a mechanical gauge stat. Thanks for all the help with this.

    Or just wait a few years for things to warm up.

    possibly overtreated engine oil with LubeGard

    So I do testing to make money, and I'm fairly decent at it. I just did another test drive. After recreating the scenario (meaning driving it, waiting a couple of hours, and watching things carefully during startup), it definitely seems like the oil is raising pressure as the engine warms up...

    possibly overtreated engine oil with LubeGard

    Thanks, that's exactly what I thought! There's something going on that I don't comprehend, haha! Non-intuitively, whatever is happening is making the reported oil pressure low when it should be high. I'll check it with a mechanical gauge. Edit: great to hear about billet cam availability :)

    possibly overtreated engine oil with LubeGard

    Yeah. I heard that as soon as the surface is compromised, those cams are toast. Makes total sense about the rod/main bearing clearances! I wonder if that's what's going on - when the engine is cool, the oil pressure on startup and idle is really low, but once warmed up it's reasonable. Does...
