We got code about 3 weeks ago. P0332 which was caused by pressure washing. We opened it about a week later and changed knock sensors with same wiring. Code came back up including gaskets. We opened it back up and changed wiring but not to the ACDELCO brand. So fastward to today the check turned on after running 17 miles. Got the P0327 and P0332. Should i open it back up and change wires or change both sensors and wires to original acdelco. Truck has 114k miles

Did yo use only AC Delco sensors. Did you

torque them to correct specifications?

Yes put only ACDelco wires and sensors in. Make sure you do the TSB about the silicone dam

Yea i used acdelco sensor but different brand of wiring. But just now we tested oms with miltimeter through the wiring harness plug and it’s getting 100oms. What should i do? And one of the new acdelco sensors that i bought incase i need to replace the ones it has goes down in oms from 100.

      Actually, it probably was the brakes.  It's weird the way the messages came across, but I took it to the dealer thinking that something was wrong with the sensor and in fact, the rear brakes were shot.  What I don't understand is why the messages never said, your brake pads are low.  First I got the message I posted above, taking about new pads being detected.  Then I got a message saying that the system needed repaired.  It never said, change your brake pads.

      Lets Talk Z60 Suspension

      Did the KYBs keep it the same height in the front? I was concerned that pre-assembled assembly would raise it up an inch to standard non-z60 height.. I guess which it would make the rake 1 inch instead of 2 inches.

      Thank you for keeping the train on the tracks and for a thoughtful engagement. I enjoyed the reflection on a previous stance to refine and improve your position. I like that inquisitive flexibility about you Atlas.    No the process isn't sterile. Hundreds, perhaps thousands of miles of piping, vessels, pumps. Chevron, the people I worked for, were keenly aware that there is a market for what is known as their "ISOCLEAN" line of lubricants. These are lubricants that are the same as those sold bulk that are further processed by filtration to a level your particular application demands. They will filter and package and provide lab documentation as required. Do not kid yourself. Every gallon of oil that goes into a Chevron Turbine, reciprocating compressor, generator is prefiltered and tested before being charged. Lest wise it was when I was there in the plants I worked in.    There are requirements set by manufactures for the cleanliness of the oils used in their equipment. OTR such as CUMMINS has standards shared with customers on this. Commercial interest selling to Ma and Pa do, but don't share that information. Not even upon request but internally, they do exist.    The GM study sited, (Graph from Machinery Lubrication in previous post) only shows "relative" importance.  I find that fascinating. By constructing the graph like this they admit there are dozens of factors in engine life and via scientific method determined the effect of 'relative cleanliness' on engine life not in miles but in 'FACTORS'. This allows a certain amount of reverse engineering does it not?   They even provided some touchstones. Beta 75 as a reference point. Wonderful stuff!!   Smaller blenders CAN and some DO take the time and effort to do better than a refinery or large bulk blender, like Warren Oil, in improving the "in the can" cleanliness. No I don't have a list but testing could generate that information.    Again, but one of several levers we can pull to improve engine life. The simplest is keeping a clean work station while doing your own oil changes.
