Title: 6,2 diesel powerless
Post by: Hollowman on September 24, 2014, 02:10:37 pm
Hey! After a long time, I am back. A lot of family issues and such to deal with. Anyway, I have a 6,2 diesel, a 1983 chevy van, with a 700 transmission. Lately, it's totally powerless on fourth gear. It runs fine until 4th gear kicks in, when it is still fine, but with no power. My best clue is that the diesel filter needs changing. As far as I understand (without actually searching for it, since the van is parked outside on the street and it's cold and dark), the filter is really easy to change, and it's one of the few things in the van actually located where you can reach it.  8) Does this make any sense? If anyone here is selling them, I can change the filter tomorrow, and be happy!

If you keep it in drive (leave it out of od) does it have full power?
As far as the fuel filter, why not just buy 1 at the parts store?

Well, I didn't drive it outside of the OD mode, but I couldn't drive it faster on the third gear at kickdown. On the other hand, I was a bit careful, and didn't push it too hard anyway. I ordered a fuel filter today, so I will have it tomorrow. Hopefully it will solve the problem!

Now I get it! By "here", I meant in Sweden, preferably close to Malmö, not at the forum.  :)

That makes more sense, kinda seemed odd that You were looking for a fuel filter on this forum.
When is the last the filter was changed?

I have owned the van more or less a year, and never changed it. It might have been replaced by the guy I bought it from, that had owned it a year or two, but I am not sure. I thought so, that's why I didn't do it sooner, but now I start to doubt it.

transmission could be hooched, they are know for slipping in overdrive when they are about to go

I am not totally sure, but I don't think it's slipping. It just has no power. If it was slipping, wouldn't it seem more like it had power, but losing speed anyway?

On youtube, there's a video of a guy with a 6,2 diesel Suburban '88 changing the fuel filter. He has another filter than I have, and some air bleed and water drainage that I didn't see on mine.  He has four holes on the fuel filter, and I have only two... How do I get rid off the air in mine, before starting it?

Via google, I found someone saying that this engine gets rid off the air automatically while glowing. Is that reasonable? Since it doesn't have a valve for this close to the fuel filter, as I have seen on other chevy diesels, the other option would be taking off each "inlet" to the engine, and let them bleed, but that would take hours! It's almost impossible to reach some of them, since it's in a van.

When  I change a diesel fuel filter I just fill it with auto trans fluid

I've had people tell me that was bad for the engine but I've never had an issue with it
Title: Re: 6,2 diesel powerless

The problem with the filter is that the holes are on the side, so if I don't dismount even the filter holder, everything I would put in the filter would leak out before the filter is in place.

Never seen that before

Might be a good time to upgrade to a spin on fuel filter set up.
Mine has a primer pump on top and a bleader screwvon the front.
It make changing filters and bleading the system an easy job that won't drain your batteries.
You can buy everything you need at Napa for about $125.

Any idea what kind of snake it is?

It's in north Georgia. 

It's just a black snake
 
Not only are they harmless. They are nice to have around
They eat mice and chase off other snakes

Once they get a few years old they are really long and skinny

This guy was over 6 feet long

Once you get over the initial shock of finding a snake under the hood and look at it a minute to determine if it's a poisonous or harmless

The poisonous snakes have a shorter thicker body and a very large triangular shaped head that is noticeably wider than their body

A non poision snake is usually long and thin and the head is about the same size and the body

Wanna see the spiders that are always sitting in the bathroom sink ?

They are harmless too. But still spooky (http://img.tapatalk.com/d/14/10/06/8a7y3eje.jpg)

Snakes and spiders are not the only thing I gotta keep an eye out for (http://img.tapatalk.com/d/14/10/06/7avepy5a.jpg)have a trail cam in the front porch

If you look close you can see the back bumper of the C-10 in the right side of the pic

Thanks for the Lesson on wildlife. Hopefully next time I see a snake,  I can tell that its harmless before I run away.
I think poisonous snakes are a rare sight  here in Mass, but this is good info to know (and I'm running away regardless).

Yea I'll pass on the snakes and spiders. Bears and bobcats and little brothers are no problem.

Copperheads are the most common poison snake I see

Rattlesnakes are around but not as many

Just remember that 90% of the people that get bit by a snake are harassing the snake at the time

If you just back off and give em some space. They will almost always go somewhere else

Water Moccasins are a different story.   They are very aggressive and will actually come twards you so they can bite you

I just picked a filter set up at Napa to do this modification on another Military  CUCV.
I will post part numbers, prices,  and pictures when I Install it.
