Disney Posted May 24, 2022 Share Posted May 24, 2022 I know I got questions, and i'm sure you all will too. So let's just have a thread where we can ask @Ashley P anything! I'll start: Dear @Ashley P, When assembling brake caliper pistons, what type of lubricant should be used? I hear brake fluid is a no no.

Ashley P Posted May 24, 2022 Share Posted May 24, 2022 Dear Unlubed: I don't know. I slap on reman'd units and go. When I assembled my wheel cylinders on The Deuce, I used silicone lube (to resist moisture/rust on the outside of the "cup". (Drive through one muddy creek and that's all exposed. Then it could sit for months/years. Who's gonna pull 10 wheels to clean 20 wheel cylinders?) Signed, Slick and shiny. 1 Quote Link to comment Share on other sites More sharing options...
Disney Posted May 24, 2022 Author Share Posted May 24, 2022 Siliconey it is! Thanks! How's the house coming along? Quote Link to comment Share on other sites More sharing options...
Ashley P Posted May 24, 2022 Share Posted May 24, 2022 House?? What house? A tree fell crushing the corner of the Goat shed, narrowly missing (6 inches) the Goat and the dump truck cab. It tore down the overhead wires to my shop and well pump. I spent spare time for a couple weeks moving the tree and running a temp wire for water. Me and the boys took out all remaining old sheet rock this winter. Know how to get a ceiling down that has old fiberglass insulation on it? Get into the attic with a water hose, wet it all really good, then kick it down. Zero dust. (Well, "nothing's perfect" in case the Caddy Machinist ever reads this.) Carpenters have worked a few days for me getting several odds and ends done. Leveled most all ceiling joists, reinstalled shower stall and sheet rocked that bath, opened up a closet wall for bifold doors, and started trimming the windows (interior). I'm running behind....need to get a LOT of electrical and HVAC done so they can box around some stuff. And lumber is higher now than during Covid. 1 Quote Link to comment Share on other sites More sharing options...
Ashley P Posted July 13, 2022 Share Posted July 13, 2022 Ashley P tells all: Did you know that a 1995 Mustang has a battery idiot bulb that, when it burns out, disables the alternator? Think about that until you get mad at the engineers. Quote Link to comment Share on other sites More sharing options...
Disney Posted July 15, 2022 Author Share Posted July 15, 2022 LOTS of cars have that, and have had that since the 60's that I know of. Quote Link to comment Share on other sites More sharing options...
Ashley P Posted July 15, 2022 Share Posted July 15, 2022 What's the logic? "When you can't tell the charging system is disabled we'll make sure it's disabled." PERFECT for "Build back better". Quote Link to comment Share on other sites More sharing options...
Disney Posted July 17, 2022 Author Share Posted July 17, 2022 IN a working system, the light should illuminate when key is on and engine off. If that don't happen, you know you have a problem. Then when engine starts and alternator is working, the light goes off. Quote Link to comment Share on other sites More sharing options...
Ashley P Posted July 18, 2022 Share Posted July 18, 2022 Still stupid. My electricians points ignition camaro ran well with new fuel hose and filter, until it lost spark. I'm trying to get him to let me convert to HEI. Looks like the cowl will need about 1/2" of "adjustment" for cap clearance. Quote Link to comment Share on other sites More sharing options...
Ashley P Posted November 16, 2022 Share Posted November 16, 2022 Answer Ashley P: 2008 chevy 6.0, very intermittent CMP data glitch. Customer had already replaced the CMP, I did again, still same problem. Idling in the bay and the scanner recorded a peak engine rpm via the CMP of 8191 rpm. Reality was about 2000 rpm at most. Where's the needle in this haystack?? Quote Link to comment Share on other sites More sharing options...
Disney Posted November 18, 2022 Author Share Posted November 18, 2022 Any codes? Quote Link to comment Share on other sites More sharing options...
Ashley P Posted November 20, 2022 Share Posted November 20, 2022 I think it had a CMP code, is that a P0340? Harness looks OK. When driving down the road the engine will momentarily miss or shut off, like maybe it's missing 3 times in a row. That's once every 10 miles or so. I think I saw the CMP reference have a little glitch on the graph. Quote Link to comment Share on other sites More sharing options...
Disney Posted November 21, 2022 Author Share Posted November 21, 2022 Sounds like pin fit or connector issue. Check diagram, but I think it's a solid conductor from the sensor terminal to the ECU. 1 Quote Link to comment Share on other sites More sharing options...
Ashley P Posted November 22, 2022 Share Posted November 22, 2022 There is a 1' long harness running from the CMP down to the oil pan, that connector also looks good. I've got another truck with similar issues. "My electrician" has intermittent long crank with a p0340 CMP code. I slapped one in last week, he came by yesterday saying that the starting is better, but it's sputtering/dying now. No codes. I graphed the CKP (crank sensor) and managed to have the rpm up to about 1800 when the engine lost all power and I saw the digital display show 0 for rpm just before the engine came back to life. So, I KNOW that CKP reference was a lie. If I can't see any wiring defect it'll get a CKP. CKP rarely sets a code; when the computer sees 0 rpm it just "thinks" the engine is stopped. Since the CKP is a HUGE part of some CMP code logic, maybe the CKP is the actual problem with the first truck that sets the CMP codes. I'd better do some graphing of that next.

Ashley P Posted January 12 Share Posted January 12 This back burner project that generates P0340 pretty regularly and a p0335 about 1/10 as often.....I've been driving it about once a week. Seems to be getting more frequent, CMP and CKP graphs show wild fluctuation with CMP. Today it died on the return of a test drive. Zero CMP and CKP. Nothing. Raised hood and shook the computer harness, truck started and ran terribly back to the shop....where it ran perfect in the bay. Inspecting the harness I wiggled, I found a valve cover stud wearing into the harness. Sure enough, a Blue/White wire had metal showing...the signal from the CMP. Tape and a removal of the stud and the first test drive was flawless. Motor mounts are broken, engine moves a lot....probably helped that failure.
