    Oil pressure low

    But before the rear main seal repair I probably have to add oil once or twice a week. Just driving 30 minutes back and forth to work a day.

    Oil pressure low

    Need to recalibrate that answer I just had my rear main done, she’s still full of oil. And the oil pressure after the rear main repair remains the same. (Still leaking from front main, timing cover, & pan gasket.) not nearly as bad though she don’t even stop on the ground. The rear main would...

    Oil pressure low

    Appreciate yall for the help. Also another mention about my rear main it’s absolutely just puking at this point. And im honestly really pointing my finger towards that. When I park oil is just all over my bell housing, watching the drops of oil fall down every 2 seconds after parking.

    Oil pressure low

    Yea I have the special socket for it at my shop. It works on the new OEM delco one I just bought, but won’t grab on the existing sender that’s in my motor right now for some reason… thinking the previous owner already tried this LOL. We’ll see what I got myself into. Worse comes to worse I’ll...

    Oil pressure low

    Oil pressure low

    I’ve already replaced my o ring. Red to red. Mahle, red was in there replaced with a red o ring. My o ring really wasn’t in the worst shape, was just flattened. No cracks or major deformities. And oil pressure is maybe slightly better on average after changing that out 5k miles ago.

    Oil pressure low

    Would this cause a drop in pressure after it warms up?

    Oil pressure low

    I’ll check this for sure. I’m fixing to throw in my new oil pressure sender sensor. Along with intake manifold gasket, because for some odd reason my sensor is a different size from the factory sensor. 1” 1-16 or whatever it is

    Oil pressure low

    My oil pan was very clean. Literally had to do virtually 0 cleaning when I dropped it. Was the original gasket btw. Hasn’t been dropped/ cleaned for 230k miles.

    Oil pressure low

    Another reason I bring this up is by comparison. We have a second 2006 Chevy Tahoe 5.3 L, LT trim. it’s got 300k miles on it. 160k miles of straight neglect and abuse, as it is a work truck. Now my brothers vehicle. It makes fantastic oil pressure. Around 60 on the highway no problem. Idles at...

    Is your pressure fine now? Post sensor replacement.

    Oil pressure low

    Idk it’s like, maybe around 30 ish as of right now it’s acceptable since like I said I just did an oil change. Drove 300 miles around Galveston and Houston. HOT idle after 2 hours of driving with this fresh OC in idling just a hair above 20 PSI. Normally running idle to 35 it’ll shoot slightly...

    Oil pressure low

    And so after a few days on this oil change right now completely warmed up 15 minutes of driving I idle at about 28-30 it looks like. Completely fresh clean oil.

    Oil pressure low

    I work at an oil change place. It is a full service shop as well. I used a wix XP filter, and we used pennzoil motor oil. The high mileage comes in a box. Not faked with some cheap alt conventional. So it’s good quality oil. I always do my changes myself.

    Oil pressure low

    I’m going to replace the pressure sensor and either remove or replace that screen entirely. Will see what that does. If that does not resolve my issue I forgot to mention I do have a pretty bad rear main leak. But according to my research it shouldn’t bleed as much pressure as I’m losing now...

    Underpowered Possible vacuum leak

    Idler chirp would cause that whistling noise? And I recently had the belt off doing the water pump 3 weeks ago, all them bearings up front sounded fine

    Underpowered Possible vacuum leak

    I know these gauges usually aren’t trusted but it actually said the system was slightly overfilled, one of those autozone cans. It’s just strange to me how the ac only starts acting up immediately when the check engine light comes on for the FTPS. The ac will work fine for a straight month...

    Underpowered Possible vacuum leak

    Also will mention I get an intermittent code for a fuel tank pressure sensor which for some reason makes my ac act funny. Makes the compressor not kick on, and or it’ll be turning on and off every few minutes. Seems unrelated, just thought I should mention just incase but these are my codes...

    Underpowered Possible vacuum leak

    Nah the whine is fine I know these all whine im just pointing out the sound of pressure/ air releasing escaping whistling noise when I let off the accelerator it’s most prominent. Like a vacuum leak. Thinking that has to do with why this thing feels so sluggish.

    Underpowered Possible vacuum leak

    Where would I hook that gauge up to and what would this tell me/ what psi reading should suggest normal range
