Re: Truck won't rev

Oh sorry, bad wording, I meant that the push rod was causing issues that made it look like head gasket failure (smoke, low power, etc). But, the revving issues started after I replaced the head gasket, which it turns out I didn't need to do. Here, I'll tell you everything I've done. First I had an i...

Re: Truck won't rev

Ok, I inspected the liquid coming out of the pipe and it is oil. This has to mean I did the head gasket replacement wrong right? I can't imagine what else it would be. I don't see how I could get it wrong though, but I guess I could've.

Re: Truck won't rev

Oh sorry, I didn't answer a few questions. Paul - No, it does not idle normally. I don't have a tachometer, but I would guess that it idles below 300-400 RPM. You can pretty much count the revs, that's how slow it idles.If it helps, the truck ran pretty good before all this started. It was getting s...

Re: Truck won't rev

Thanks for the help, sorry I couldn't get back to you sooner. I've already replaced my fuel filter, so I think we can narrow it down to the intake / exhaust (I've already ran transmission fluid through the fuel system too so the lines should be good). I'm going to give my mechanic a call, I'll have ...

Truck won't rev

I have this strange issue happening right now. When I give my Pup more throttle, it just shoots out black smoke rather than increasing the RPMs. My mechanic says that the injector pump went out, and that the engines in those trucks die pretty quickly anyways, so he just suggests scrapping the truck ...

Fuel pump help

So my Pup had been at the mechanics for over a month now, and they say they've finally nailed down the fuel pump as being the issue. They say that it's not even close to making the pressure needed to operate the injectors properly. So issue found, all is good right? Well, they say that the only fuel...

Re: A few random questions.

Huh, they look and feel like foam, are they made of a more sponge-like material? Thanks as well, I will clean them, it looks like a lot of oil is getting past them.

Re: A few random questions.

Ok, I opened it up, and there is some foam that looks like it's acting as a filter and it looks like it was made for the truck.

Re: A few random questions.

Maybe I'm remembering it wrong, but I'll check again tomorrow once it's light out.

Re: A few random questions.

Mine goes to the intake manifold, and it does seem to have a filter of some sort, it's in a black box that rests on top of the valve cover. At least when I opened the black box there was a piece of foam that looked like a filter.

A few random questions.

I'm halfway through rebuilding my head, tomorrow I'm finishing putting it back together. But I spotted a few concerning things. My No. one cylinder exhaust valve was extremely loose. the push rod had a gap of over 1/4 inch, so that's not good obviously, but there where a few things the I don't reall...

Paint Color

My Pup needs some spots touched up and I was wondering what paint color I should use. Mine is the light yellow paint job like this one: 1984-isuzu-pup-diesel5speedcomplete-restorationclose-to-museum-qualitynew-1.JPG I would prefer it in spray paint if possible. I already went to O'Riellys and ACE, b...

Re: Head Gasket Replacement

Ok thanks. I have a friend who has a diesel compression tester, so I will do a test before I go off and take apart the engine. My plan is to do a compression test, then take a day to replace the head gasket, adjust the valves, and put it all back together. Then I'll do another test, and hopefully th...

Head Gasket Replacement

I'm getting a lot of white smoke when I first start my Pup in the morning, and small amounts of white smoke come out of the exhaust throughout the day. I can only assume it's something with the head gasket, could be something more complex but might as well start out with the simplest job. Where shou...
