What are you working on today?

Got the cp3 conversion done on the LML. Had to do much more than anticipated including changing all the drivers side injector pressure lines, high pressure crossover line, fuel pressure sensor and fuel pressure regulator. Fuel lines had lots of rust on them also which was the primary reason to change them (technically one time use but have reused in a pinch, I had to remove these to remove the LH fuel rail to get the crossover line out). It has so much junk in the fuel system. Even the fuel filter had rust inside it. This fuel system has definitely had water in it at some point. At least he went for the fuel filter change. Would have been crazy not to. Even convinced him to change the spin on transmission filter too thankfully . Was ready to pop from rust!

To change this crossover line service info says to remove turbo, and to remove turbo, transmission must come out. Not happening! So after some modification to a casting nub on the LH intake and removing the LH fuel rail, I was able to get it in without too much trouble. These engines are a plumbing nightmare for fuel system stuff in the valley of the engine. Far too many lines in one area all with very specific small bends in many different spots.

I can comfortably say I wouldn’t mind not doing any of these for a while. Way more work than a powerstroke and Cummins. I Still have an EGT sensor to change, but that’s an after thanksgiving job.

Total cost for this job going to be around $7400 Including the cost of the conversion kit (which he provided). Had to replace just about every hose I touched I cludng heater hoses, they were all seized to the metal pipes and had to cut them off and peel them, charge air cooler cold side hose the locks were broken so had to replace that also, had codes for coolant temperature low so changed thermostats and tons of other seals and gaskets. Parts are not cheap for these engines.

I’m my opinion, not worth it at all given the condition of the chassis, but he just bought it and this is what he wants to do and knows about the condition of the chassis. Truck also has nearly 200,000 miles.

@clinebarger - would you think this is a case where maybe the TC started to slip, causing the heat and fluid degradation, or is this where the driver caused the wear and tear?

These newer transmissionmissions seem to be so good at staying in lockup that they don’t create as much heat internally as they used to?

Truck is awfully clean and the wheels are fancy - does the vehicle tow a lot?

It tows a bass boat.

*All the material in the pan is the converter clutch lining, I haven't vacuum tested the valve body yet....But I bet I'll find some of the Pulse Damper Pistons worn out which can cause poor TCC control & burn up.

*The Thermal Bypass has a broken spring cup.....This will cause the unit to overheat from the bypass not opening. Strange thing is not all thermal bypasses used a plastic spring cup but a steel one?? 2014 & up 6L80's can also suffer from this.
I tap the bypass body with a 1/4" NPT tap & install a plug so it will have full time cooler flow.


Got the unit tore down, Inspected, Case washed.....And gathered parts which is the more challenging aspect for me because the time it wastes.
3 different GM dealers, WIT transmission parts, Converter shop & Summit Racing to get everything, Everyone is in "Holiday Mode" whether its on the road or behind the parts counter:rolleyes:

It's getting to where my machine shop work is repetitive jobs I've already posted several times...link bars, hydro boost, unit bearings etc etc. I like the work but it's going to pretty much be repetitious posting about every three weeks. Tomorrow I am going to change the oil filter on the F-150. I'm getting some intermittent timing chain "buzz" for a few seconds on cold starts, going to swap the Mobil 1 filter for a plain old motorcraft to see if the issue resolves.
 
2009 Trailblazer with 255k miles but on a second engine: replace leaking oil pressure sender. Found it significantly overfilled on the dipstick. On a guess I drained 2 qts and that put it just over the high mark -- good enough

It needs a lot more work (rear brakes, one axle seal both front and rear) and it actually drives well and is worth the investment, but the owners are cheap.

1999 Jeep Cherokee: replace rear brake shoes and hardware.

I feel you on chasing parts!

I’ve had to get parts from 5 or 6 different places for this 6R140 I’m trying to get together. It’s been challenging for some reason.
 
Mounted the snow blower on my LT150 today because apparently we are getting snowmageden on Saturday here in eastern Iowa.
I fired up my Simplicty blower and soaked the shoot with fluid film last weekend. I hoped that would keep the snow away.
 
Thanksgiving wrenching: a guy showed up at my place for other reasons and the right rear of his WJ had the worst wheel seal failure I've personally seen. Of course what actually happened was wb failure and then seals don't work so well when axleshafts slop around.

Fortunately O'Reilly was open today and stocked the bearing and seal -- albeit Precision which is "meh" IMO

On a bright note I got to use my KTI MegaHammer to pull the axle, which I realize was overkill but I hadn't used it yet. They're still $107 on Amazon:

That black racing stripe in the wheel well is gear oil:

The other day I did a white trash repair on my 2002 Sunfire, Shtty Blue. Pulled the alternator off and added some more fresh grease to the front bearing. I could not properly access the rear bearing (need a sizeable soldering iron to desolder a few points) so I used a small drill bit to put a hole in the seal. Used a needle to inject some grease and then sealant to patch it. Will it hold? Who knows but im not throwing more money at this beater. Hell yeah brother!!!

Today I have to bring the Trailblazer to town and get a tire patched. Im pretty amazed we got a year on the new tires before picking up a nail.

I've greased strut mounts in the same manner. Gotta be better than nothing
 
@D60 it certainly is. My dad showed me this method as a last ditch effort back in the 90s. While the bearings are noisy, there isn't any slop, so why not? It certainly quieted things down and I will do this one more time this week to work some more grease in.

Probably way, way more common in parts of the world than one would guess.
