Today i finished putting a new gasket on the timing gear cover. had to take the whole front end apart, radiator,intercooler,condenser,bumper ect. well got it all back together. Truck started thank god, but when i took it out for a drive it made a loud whining noise and i had no boost what so ever

HELP

Check for a boost leak at one of the intercooler boots.

 

You might have forgotten to tighten a clamp down for the elbows, or one is leaking due to improper fitment or is has split. Double check all your connections you had apart!

Beat me to it!^^

 

checked them, look good to the eye and feel, but will check them more in depth tommorow. now the EGTs are getting very high.

 

the boots are good. now what, could it be the timing slipping, i did notice that the hard lines going to the condensier and then going back are bent bad. Could this be it also they are bent preety bad.

 

Everything you have mentioned points to a boost leak - or you left a rag in the piping.

The A/C condenser lines have nothing to do with your problem.

 

yeah i agree but i cant find that darn leak

 

maybe something in the fuel system?

 

Not with high EGT. You have a boost leak or a restriction. A rag left in the intercooler pipe will cause this sort of problem...

 

This is definitely a boost issue. High EGTs are the number one tip off. I have made up adapters to hook up the inter cooler to a shop vac with the blower feature, I cap one end and pressurize the system, then i listen with a stethoscope for a the leak. Also, by murphys law, the inter cooler boots will always crack where you cant see them, be sure to use a mirror to look completely around them and squeeze them with your hand to expose the possible crack.

No kidding about the not seeing the cracks. I had a crack in one of my boots on my 99, took me quite a while to find it. Finally found a little mark on a boot, squeezed it and nothing happened. So I caped both ends off and put 20 psi to it, sure enough that little crack opened once under pressure
