I searched through the site and found good threads about this, however the most recent that I found (at least with my limited search abilities!) was about 1-1/2 years old. So what do you all think? Is this still the way to go? Are a lot of you using the D-Tech?

Too bad we weren't closer to each other - I'd swap you my 3.73 's for your 4.10's! Nice looking wheels! Bilsteins are the way to go!

I just took at look at mine. I'd call the engine "cool", but not cold. Outside temp is 27* and the truck has been sitting for about 4 hours. The best I can describe it is that there is resistance when I rotate the fan. If I try to quickly "spin" the fan, it pretty much stops immediately...

Do you have a mechanics stethoscope (or a really long handled screwdriver... put your ear on the end of the handle)? Maybe try poking around with that and "see what you hear"? How long can one safely run the engine without the belt on? Maybe the next time you hear it at idle, take the belt...

SD: The better airbox, which you likely have (I have it on my '98), would contain a round air filter, not a flat one. The box, itself, mimics the shape of the filter, it's just "flattened out a bit" and not perfectly round.

In laymans terms (which is typically the extent of my ability!), the TM won't hurt... but the Vac system is better (not by a lot, but still better). The Vac system will adjust for things like atmospheric conditions and altitude, thereby giving a more precise control of fuel usage. Maybe...

Just an idea, but maybe it will help in narrowing it down... The next time you get the noise, pull over and put the truck in neutral and rev up the engine. I'm absolutely not an expert, but I would think this should at least tell you if it's drivetrain related or engine related.

Do you have a boost gauge? I see you have a turbomaster, but do you see any correlation between the loss of power and boost pressure?

Is this a new noise, or did you just acquire this this truck and are unfamiliar with the normal sounds? Is it the exact same noise when comparing accelerating and decelerating? How about if you simply rev up the engine when in park/neutral?

You're dead-on about that!

Thank you, Leo. Your post helped as it forced me to take a second (actually 3rd or 4th) look at this. I believe I may have been mistaken on what is leaking. It appears it may be from my secondary oil pressure sender. I removed it, put a plug in it's place and cleaned everything up. We'll...

Hi Leo, The part that is leaking is where the center section of the turbo mates to both the turbine and the compressor. The oil is seeping out from where these pieces connect together. It's the area that gets held together by those 8 (?) bolts with the funky, rectangular washers. I suppose I...

I've noticed oil leaking (more like seeping, than leaking) out of the area between the turbine and the compressor. It's seeping out where turbine and compressor attach to the center section - in the crack/gap where the bolts (and rectangular washers) are - I guess the "mating surface" is a...

Louis - Last time I checked for TSB's, I don't recall anything related - the only thing was about the rear brakes. It's funny you mention the winter cover... I actually just came up with a way to save myself $50 on a winter front about 20 minutes ago... and, no, I'm not using cardboard! :lol...

Here's what I found... I ran the truck in the driveway at 1050RPM's for about 20 minutes (approx 185/190 showed on the dash temp gauge and I could see that the t-stats were opening and closing by the slight movement in the needle). I then took IR readings behind the tailpipe right before where...

All good points. Louis - I did bleed the lines (actually a few times), so I think from that standpoint I'm good. Mike - that's great idea about the small pipe! It was mentioned up above about installing some type of restriction to the front core, but the only thing that had really come to...

I have checked the lines from the engine all the way to the rear core - I can confirm that nothing is pinched. I will feel the supply line and the return line this weekend (near the rear core) for temperature. When I had flushed everything (a little while ago), I flushed it both ways and got...

Well, here I am again with the rear heat problem returned! Cold weather has rolled in. In normal driving around, the air coming out of the rear vents never gets above "cool" (I know, real scientific, huh?). I played around a little bit today and drove awhile with the radiator cap (coolant...

Dan, Here's a couple of pics of my radio to give you an idea of what an aftermarket set-up might look like. Some may come with a different "adapter plate"/kit to fit around the new radio, but you probably get the idea.

I originally had my pyro in the downpipe. When I put the new engine in, I took advantage of having the manifolds off the truck to relocate the pyro to that flat spot. Obviously this was easy for me since the mani was out of the truck... but another way to do it is to goop up the drill bit and...
