Man oh man, I done said about every cuss word there was in the book this moarning.

I'll ask my question before I get into detail about my truck. I jumped in my fathers truck this moarning and the check engine light came on. It threw a code "P 0514". I had a bookmark that displayed all the codes for our trucks but lost the link when I redid my computer system, anyone have that link on hand? I know the link is from DTR somewhere, just can't find it. If memory serves me correct it is the battery temp sensor or something. But anyways on to my drastic story.

I'm in the process of installing my EGT gauge, boy is this one big pain in the you know what. Anyways. I removed my manifold just to be on the safe side of things when I drilled/taped it. Getting that piece of iron off was enough for me to call it a day right there. So I remove it and drill my hole, right were the #3 piston would be if it were mounted up. After tapping it I get ready to put in the thermocoupler. Well low and behold it dosen't fit. I sortive knew in my head from the begenning that the peice was to large. Keep in mind now, I got my gauge kit from Diesel Manor, ISSPRO was the company I purchased them from. When I got the kit in the mail it seemed to be missing a few things. I had no compression nut or fitting for the boost hose, I had to purchase one seperatly. There were no instructions in it either also I seemed to be missing some bell reducers in the kit. I had two large bell reducers but they are massive & I have no idea what they are to be used for.

So right now I basically have a manifoldless truck. I looked at ATS's 3 pulse kit that was pre tapped but didn't want to spend $410.00 on it. Luckily a buddy of mine at the Dodge dealership located me a new one for $150. This sure was a costly mistake on my part.

I also called up ISSPRO and had Scott, whom btw was very helpful in my questions I kept pestering him about, send me out a new fitting for the coupler.

Does anyone have a good detailed set of instructions mabe with a picture or two on how to tap this thing w/ the CORRECT size drill/tap. I located 2 sets of instructions both indicating a different size tap/drill.

Sorry for the long post just had to get this off my chest.

 

I got great service from DM. Sorry about your experience. I ordered a tap from them to match the thermocouple and I already had the drill bit. I started small with drill bits and worked my way up to the correct size specified. Then I used the tap. The tapping went really easy. I kept an eye on the depth as I was tapping and then cleaned everything up. I left the manifold on but I put some paper in between the manifold and the turbo and then pulled the paper out afterwards with all the metal still on it.



Here is their tap size to drill bit size table for the thermocouple.

Thanks tbone.

How did you drill/tap your hole w/ the manifold on? I tried all sorts of ways to get a drill in there to do it but couldn't to no avail. The drill wasen't centered how I wanted it to be and I didn't want to have it in at an angle. Hell I even went out and bought an angled drill but that didn't cut it. This project keeps getting pricier and pricier as I go on.

Just so I can clarify this, you used a 7/16 drill bit to drill the hole and a 1/4 NPT tap to thread it? I did the same thing and my thermocoupler bolt was still to large in diamater to fit in the hole.

Oh before I forget let me ask you this also. On the circutry(sp) box in the cab of the truck for the EGT gauge, I have two lead wires that go from the thermocoupler sending unit, I know what those are used for. But I also have two small wires comming out of it that are just stripped wires, do they connect to something?

 

Some days are diamonds, some days are coal.

 

Your not lieing. Today was deffinetly a coal day, although it cost me as much as a diamond. I even splurged and went out and bought myself a 12" drill press.

 

Anyone happen to know the link to all the codes for our trucks?

It must have been a really bad day for you. The two wires that are stripped are for the power for the box. Red is power, black is ground. It is written right on the green label on the box.
Hope this helps

Pull U 2- Thanks for the link I appreciate it.

mishkaya- Thanks, I knew they were used for something I just couldn't figure out what.

Im going to pick up my new manifold tomorow and try this one more time. Hopefully I get it right.

 

I got my gages from Diesel Manor and everything was there, no problem.
Even had instructions with color pictures.
I used a 1\8 npt [national pipe thread] tap. I started with a small drill bit and kept going up until I got the hole to 11/32nds and then tapped it with the 1/8 npt tap. I had to start the thermocouple 2 or 3 times but it screwed in with no real problems. Sorry you had a problem with DM.
If had been RPM Outlet I could understand.

 

Just put a 3 gauge isspro kit in my buddies 12 valve from DM also. No problems with good instructions, and all the parts. before you spend $150 on a new manifold; cant you just weld a bung/nut in/over the hole you drilled, and screw your thermocouple into it? I would think there would be a way to get around spending $150 for a manifold.Good luck!

Nate...

Make sure you get an NPT tap... On the side of the tap is should indicate what size drill to use.

I drilled mine by pulling the plastic inner fender well.. it is amazing how much room you get by pulling it out. It is 7 or 8 screws to remove, also be careful there is a set of wires that attach to the fender well with a clip thingie.. I was able to get an 18volt Dewalt drill in there with the fender well removed.

I bought my guages from piers and it came with a larger Isspro t-couple.. I halped someoen else put theirs in and they bought the set from DM. I don't think it was an ISSPRO probe though.

I called Diesel manor and was not able to get things shipped as they promissed and they just kept lieing to me about ship dates so I told them where to shove it and went with piers.. Couldn't be happier.. Complete set and delivered when promised..

So why do you need to get a new manifold.. If the hole is to big buy an adapter/ bushing to get the hole down to the right size...

You don't need a new manifold. Drill and tap to the next larger size (1/4" NPT, or 5/16" or 3/8", and use a reducer. When I mounted my nitrous jet, I too drilled too large of a hole for the tap, and ended up just drilling it to 3/8" and using a reducer back to 1/4"

 

Did you all receive reducers in your kit? I think I might of received a returned item or something, it's a little fishy.

Anyways I already got the new manifold and im going to give it a shot once more. I'll let you all know how it turns out.

 

No reducers don't come in the kit. I had to go buy one because I drilled the hole too big. I think it cost about 3 or 4 dollars.
