I wanted to get a sense of varnish with the boroscope. it used to burn oil. HPL EC and another brand of stiction cleaner seems to have corrected that last year though.

After tightening the 2 loose front bolts on the VLOM, the oil pressure is back to 37ish PSI. I only tightened the two in front that were accessible, anf it helped a lot. Plan to pull the intake manifold and check the rest of the bolts on the VLOM. Replace the seals. Definitely check the two...

Humanoid used to be called Anendroids. Guess google took that name. They are HR robots. Used to make sure people are working :D

Update, Watched a few YouTube videos about AFM cyl deactivation. At the advice of a youtuber, I checked the VLOM manifold bolts to see if they were loose. The front two are easily accessible. Sure enough, they were very loose. I could tighten them 2 turns with my hand. I tightened the two I...

Tried the nose-down overfill method to check pickup tube O-ring. 2.5 quarts over filled. No change in pressure. Incline in my driveway is pretty steep. Tried nose up, and nose down a few times. No change either way. Gonna be traveling this weekend, so I drained the oil, put in M1 0w40 FS Euro...

Put the PF48 on. Drove to town and back. Lowest pressure ive seen so far. Edit: This could simply be the new Oil Sending Unit. Perhaps I didn't get all the oil out of the connector, from the old OSU that leaked oil into the electrical side, engine oil temps may have been warmer than previous...

Yea still about the same. Engine is smooth, no tics, no taps, no unusual noise of any kind. (I even turned hy hearing aids up all the way to listen 🤣) not even on cold start up. This may not be a problem per se' other than its getting long in the tooth. Will change the oil filter with AC...

New AC Delco OSU installed, clean oil screen. Hot idle shows 26-27 ish. Took a hot minute to clean the oil out of the connector. May need to replace the connector. On another note. Here is a pic from down the oil fill neck. Couldn't quite get the inspection camera to go where I wanted it to.

I see your point. I didn't state it clearly. No changes to alternator charging system. I put the external charger on all my vehicles every few months. The point I intended to make was: Usually full SoC in couple hours when on the bench charger. This past charge on the suburban, took...

Following advice, despite being hard headed., I pilled the OSU and screen. Screen is clean and clear. OSU, on the other hand had oil on the terminal side. Headed to Autoparts store chain to try and get a replacement. Hoping for OEM, but will have to take what I get. will report back after its...

I have not rulled it out. Just hoping to find a les expensive repair if one is available. There are posts on a few forums that mention, if oil pressure is low at start up when cold, but returns to somewhat normal at operating temp, it is likely the pickup tube O-ring. Not sure if this is...

Today, I took the Burb to run errands. Drove to nearby town ~17 hwy miles, dash temp showed 37°. When I got got in the city, first stop light, oil pressure was around 26ish again. Current oil is still amber and has maybe 150 miles on it. (Edit) so the historical "normal" oil pressure I was used...

Just wanted to clarify. I have a bench charger that I put my batteries on every few months. Normally takes maybe 2 hours to bring them to full soc. Recently, it took several hours in this case. When a car is started, it pulls a lot of amps. If the car doesn't run long enough to replenish the...

Yea, initially yhe change was for the 2-stage oil pumps. Mine does not have that. It increased the bypass from 16 to 22 psi. According to Frams website, 22 psi is now acceptable tor this engine.

The only larger filter I am awaee of, is for the 2015 and up GM 5.3l. It's a little longer maybe 3/4". However it has a 22psi bypass rating instead of the 16psi for th 13 model year. Frams website now shows that the 22psi range is suitable for the 2013 suburban
