By a 1/3 more oil you mean in volume not pressure correct. What about your time to build max pressure on start up, what does yours do? My fitting arrive late last night so maybe sometime this week I can pull the sensor and check the pressure with a mech gauge. This is my first LS and first...
Back story
Bought the truck 1-1-22 145,017 miles 5400 hrs no leaks no oil pressure issues IRRC it was around 30 at idle and over 40 on the highway. I do not remember how fast it built its full pressure. it was 74deg in Fort Worth when I bought the truck and by the time I drove it the 45 miles...
Are these factory wires? They say MSD on the boots. I doubt they are but figure I would ask. I think its time for new plugs and wires. Took it to the car wash and driving home had miss on #6 open the hood and there was water all over the engine bay. Guess I need to start replacing cowling...

So chasing a few issues on the Yukon and came across something on the Mitchell wiring diagram I don't understand. In the attached image the wiring diagram keeps referring to a 10 series and 20 series. I have circled them in red. Is this a connector series or a harness series? How do you know...
Ok so just drove it to diner and back I had light on both panels going there and looked to verify they where still on when I exited the truck. Come back out start the truck and they are not working again.
