Re: Working Man's Burbon

First oil change time now I have 500 miles on it. It came out well. No bad things in the oil pan or filter. I did discover that the nice Milodon oil pan I put on it has a draw back. The drain plug has a built in magnet. A super strong cobalt magnet that I'm sure grabs any iron even remotely near it. The down side Is the when removing it from hot oil pan the plug won't drop clear but the magnet sticks in the hole and the hot oil goes everywhere but in the catch pan. And while on the subject of catch pans I am advising against buying the oil drain pan in the photo. It is good idea poorly executed. The pour cap will not seal and it leaks oil. I tried to exchange it but none of the ones on the shelf were any different. Photos of the drain plug and the iron filings on the magnet. No pieces of any concern were present on it, or in the drain pan. I cut the filter open and it looked good too.

Re: Working Man's Burbon

I scored some stuff off of a 67 Burban at 205 Auto Wrecking. One of them was an early thermostat housing spacer with the bypass hose. With some help from some friendsI removed the bypass hose fitting and modified a 3/4" to 1/2" bushing to maximize the amount the sensor would protrude into the water flow. Then I installed my existing sender on it and put the sender I got from the wrecking yard in the water neck. I can now compare the difference between the senders below the thermostat and above it. And after a couple of days of switching back and forth I find the sender below the thermostat reads noticeably lower than the one above. Admittedly the lower sender is not in the middle of the water flow but it isn't shrouded by the housing. But even in stop and go traffic it never gets anywhere near the same reading as the upper sender. (The same sender used to read higher when it was installed above the thermostat before I put the spacer in.) The upper sender stays low until the thermostat opens then it jumps up and stays pretty much steady after that. The last photo is of the before set up on the old motor.

Re: Working Man's Burbon

I had been driving the Burban to work every day (which for the last month has been every day) and now that the floorboards aren't vibrating from the carrier bearing and drive line, the noise from the rear of the truck was much more apparent. I dropped the WMB at Six States to have them go through the rear end. (At the recommendation of a board member. My old rear end expert retired and moved somewhere dry) I wanted to be confident I could hop in the truck and drive to Seattle if I needed to and I wanted confirm if the ratio was a 3:55, as the PO had said, but I had doubts. I dropped it off at 7:30 in the morning and at 8:30 they called me to say there was about 500 pieces of the carrier sloshing around in the bottom of the axle housing and one of the axles were junk. They were unable to pin point why the carrier was disintegrating but the left axle had lost a bearing in the past and the PO had put a bearing saver on the axle to but it was too far gone to work over the long run. He had also put a bearing saver on the other axle but nothing was wrong with it. After removing the bearing saver the axle checked out and was reused. When I asked about the ratio I was told it was a 3:07. (Which helps to explain the lethargic manner in which the truck accelerates) At this point I got lucky in that they had a used posi carrier and a set of 3:77 gears they could put in the truck for me. So now with all new bearings, one new axle.and a new ring and pinon the truck is SO quiet and smooth. With the exception of the posi is very grabby and causes the truck to shudder more than any other posi I have ever experienced. With about 125 miles on it it seems to finally be getting better. I talked with Six States and they had me bring it by and put some more posi additive in the rear end and want me to call then if it isn't better in the next 100 miles. The hard to believe part of this is the old ring and pinon show no damage. I wish I would have thought to get a picture of the remains of the carrier. It looked like it was disintegrating. Just waiting for the posi issue to get resolved before going out and seeing how much quicker the truck is. In addition to everything else the speedometer is now correct or at least very close. Win! Win!

Re: Working Man's Burbon

I like these kind of threads. Always something to learn from them. Keep up the good work on your burb.

Re: Working Man's Burbon

Thanks! And for anyone who was wondering about the 3:73 ring and pinon I ended up replacing the 3:07's with here is the information from the box. This is a thick ring gear meant to be installed on a 3 series carrier that was designed to use 2:76 to 3:42 ratio gear sets.
And the Posi chatter issue is getting better.

Re: Working Man's Burbon

Found a box of parts the shop put in under the back seat in the WMB from the bad carrier. Man I was certainty living on borrowed time.
