wannadiesel told me someone here has a list, and hopefuly a pict, of the thing they made up to check the plumbing from the turbo to the intake to check for leaks. I was hopeing someone had a pict or to and could send along the parts list for the thing. I would like to put a pressure gauge in the thing to make it easy to monitor. How much pressure should I charge it to and how long should it hold it?

Where is the most likely places to check for leaks? With the mods and the 16cm housing I can only get 18psi at best.

Thanks for the help

IMO, the only thing that you really need to psi test is the air to air. The rest of the intake can be eyeballed. Check all hose clamps, AFC line etc.

 

When you say air to air what do you mean. I was goin to take the hose off the outtake of the turbo and off the other end at the intake to the engine, plug both ends and pressurize that system. How long should it hold pressure and is 20lbs about right?

 

Pressurize it and spray everything with a soap/water solution. Any leaks and you will know in short order. ;D

Monty was referring to the aftercooler. Which sadly is the most likely culprit since you went over pretty much everything else already if I recall.

Good luck with it!

Lenny, at Dynomite Diesel in Monroe wa and I are in the process of building some of these pressurizers for Dodge and Ford diesels. They will be a complete unit with an adjustable pressure control and air guage.
And FYI, I wouldn't go over 15 psi for testing.

Dave- Why 15psi? Just curious what the theory behind that number is.

I used some dense rubber, 1/2" thick and cut taper or an angle on the O.D. and drilled and tapped a 1/4 NPT hole in both. Put a shrader valve (sprinkler system blow out valve) in one down at the turbo outlet boot and a 0-100psi gauge in the one up on the inlet boot then use the stock tubing clamps. put 20psi. and let it sit for 20-30 min.. If you have no leak down cool 8) other wise use soap water if nessacary to find your leak.

By the way the boots will swell a lot w/ only 20 psi. and keeping your self clear of a plug blowing out is a good idea.
That's probably why hdm48 recomended 15psi, I guess what ever your comfortable with. ???

Sorry I haven't replied to your question. Been very busy.
The reason I say 15psi max is for two reasons.
1. that's all you need to find a leak.
2. if for some reason the thing pops off the turbo, anything more than that can cause serious harm to you or an engine component.

JFYI
Though in a set of POD's and that boost will goto 30 PSI on a good hill with no pump mods....

 

Ok, sure you make that much DRIVING. I make 45 psi. But I don't have my face or any other body part near it when it makes that.
What I mean is, when you have pressure in the system, you are right there in the way if something comes loose. I've had the darn thing pop off while testing and it sounded like a gun shot right next to my ear. Plus the tester flew forward against the alternator and then up and out of the engine compartment. I'm sure if my hand was in the way, it would have made quit a dent in it. Or if it had hit me in the face (no comments here) it would have made me better looking.
It's more of a safety issue.
