Re: 87 V20 D/D and Road trip Burb

So the weather has been starting to change, and after my last backcountry road outing. It's time to get a matching set of gears in my Burb. I have been putting this off for too long. I think it has been a yr now since I swapped the blown out semi float for a 14bff. In the process I put the wrong ratio in.

So I need 3.73 gears. I have 4.10 in it now. With the 285/75/16 tires and the th400, the motor is running a tad high in the rpm band on roadtrips. I don't want to swap a 700r4 in, or go to a taller tire.


After looking into the cost of a re-gear. I decided not to re-gear. I have been looking for a complete used unit just to drop in. I had lined up a proper donor from a 86 C20 Burb(gray) that was a factory 454/th400 truck. It even had the proper length e-brake cables and connections. That was two yrs ago(yes I had a 14bff swap planned). Then I sold it a yr later. Sob!

Re: 87 V20 D/D and Road trip Burb

Fast forward. Came across this gem. I need to crawl under it and confirm, but for less than the cost of the re-gear. I could bring this home. It has more than just a 3.73 14bff.

I need to find out why he wants to sell... But if it is a runner, I might just have to swap my 4.10 unit into it and drive it. Or turn it into a donor.

Re: 87 V20 D/D and Road trip Burb

A few of my fave codes.
GT4 with G80
L19
MT1
ZW9 because I have only ever owned tailgate burbs.

This thing is pretty heavily optioned. The wood grain trim package matches my wife's 91. The blue seats in my 87 are pretty worn. My 70/68/78 Burb project needs a motor, f.i. BBC would be nice.

Arrow Re: 87 V20 D/D and Road trip Burb

Well, things sometimes to wrong. In my case, more than less.

My diesel has been slowly running worse and worse. I replaced the lift pump and that helped a little. I was not seeing any bubbles in the return. It would miss in mid range rpm, it was hard to start warm, and randomly roal coal.

I sent out the injectors and injection pump.
2 injectors failed the test and the pump looks to have water damage inside.

How is that possible with only 42k on new parts?
I run a racor setup with water seperator. I changed fuel filters with every other oil change. I rarely had water in the collection bowl. I wonder if my racor setup is not the best?



At around $1100. I am going to reevaluate my situation. I am getting tired of the constant battle with this motor. Parts are a pita to source.

Big D is going to get parked for a bit while I decide what to do. I am over spending $300-1000 every time something goes wrong.

Any suggestions on how to keep mice/rats out of the engine bay and heater ducting.

Put drops of vanilla on the carpet. Maybe moth balls near the blower motor. Drier sheets have worked for me in the past but I've heard others say they had no luck with them. Sorry to hear about the 6.2 issues. Nothing diesel related is cheap these days.

Re: 87 V20 D/D and Road trip Burb

Good news.

I found a good used injection pump and 4 injectors off a j code motor for $200!

Score! I am going to try to get it back together in the next few days. I also scored another 3.73 g80 14bff! I found a guy that wanted a 4.10 unit. He suggested we trade. It looks fresh inside too.

Now I am itchy to go off road again.
