Developing problem

[carhauler]

I guess I spoke to soon about 149thou miles and 0 problems , anyone have had a problem with the air to air cooler either breaking a bellows or the air cooler itself? I was pulling a serious hill and it has got louder and louder with a kind of cross between a vacuum cleaner and a turbo whine ,I have checked all the hoses and the lbz has some plastic fittings as well , checked the silencer on top ,symptoms are EGT gets to 1400+ under any load but it's still pulling 20+ Lbs of boost ,one problem is I can't get it to do it if not under a load.....Any Ideas ????

I know there have been problems of the aluminum IC tube getting a hole rubbed in it but I hadn't heard of one on the LBZ... Might want to run your hand along it and make sure. The boots are all good? Do you have a blocker plate and is that flange sealed up good?

Best way to locate a boost leak is to build a tool that allows you to pressurize the intake. Start with a rubber drain adapter, sold at hardware stores to mate up different size drain pipe, 4"x 2" is a common size, but I am not sure on the lbz what size you will need. On the small end, reduce the size down to a pipe fitting and install a tee with a gauge on one side and an air quick connect on the other. Attach a regulated air supply to the inlet fitting and start increasing air pressure while listening for air leaks. I wouldn't exceed 30 psi to be safe.

Dave , no blocker ,never has had one , I felt the hoses all seems good , can't hear any noise at all at idle or when you rev it.

I can't do too much in the build a tool to pressurize it right now, Hope it either gets worse or stays the same 1599 miles to go !!

good luck on this. Isn't there a GM parts truck doing the tour with you? Maybe they could do some diagnostic on your truck for you?

[carhauler]

We were joking about a guy with a old impala last year that hat the GM guys darn near rebuild his car on the tour.

[Schwinn68]

that's why they send the techs! I wouldn't hesitate to ask for help if it was me. Are there any other diesel guys on tour

[carhauler]

there will likley be, I just hope I can get the other car loaded in Detroit and get down to Memphis and they Little Rock , I need someone to be under the hood while I drive...:lol:

[Schwinn68]

Wow! that's quite a trip you're taking

[carhauler]

Just found it !!!! big crack in the down pipe right where it curves down into the CAT , maybe a good welder can patch it and then I will either eliminate it or...... sure didn't sound like exhaust leak.:)

[carhauler]

Thanks to all for the response!! another reason it's good to find a new home ,now a welder in wyoming and I got it made.

[RickDLance]

Bring it to Missouri Fred!! I'll fix it.):h

Glad you found it. Where at in Wyoming are you?

[carhauler]

Im in Evanston, headed to Detroit ,then Memphis

[RickDLance]

There's a Jiffy Lube down by Walmart. The guy that manages it builds street rods on the side. I'll bet he has a welder.;)

[RickDLance]

There also used to ba a good welding shop in Rock Springs on the south side outerbelt road just east of the main exit. Room for a trailer too IIRC.;)

Yeah, no kidding... Thats a heck of a list! :thumb:

So the LBZ's could have an IC tube rub-through problem, too? I still have to check my LB7. Darn P/S hose bracket!

Good Luck Fred...hope you get it fixed! Might want to grab something to act as a rub-plate in that spot on the tube, too. Maybe get the welder to put a thicker patch over the area?

[carhauler]
