...charge air can enter a perforated hose and travel through the material to the edges. I just sprayed soapy water to look for leaks and these bubbles are coming out of the boot edge, not under it.
I've seen the same thing with radiator/coolant hoses as well, especially the blue silicone Paccar brand..
I remember the first time I blew a clamp on one of those. Scared the crap out of me. I thought I blew a front tire. Never realized how much pressure the old turbo provides.
Smoke rolled and you were in the gear box real fast.
Impressive
Full load and a hard hill. Had just dropped a gear, and pow. Had just finished an impressive hay wire job to try and get going again when a wood hauler stopped and gave me a new clamp. Told him to swing by parts for trucks, and I would tell them to give him one on our account.
Drop to the low side and find one that fits. About the same as when the front tire leaves ya......
Last one I blew I was pulling a trailer with a load of sackcrete on with as it turns out sketchy brake away wiring. Drug it for about a 1/4 mile with all 4 locked before I could turn off and as I was turning had to get on it hard to get it moving and blamo tossed a boot lol.
That material is real bad about sticking to the pipe and deteriorating inside after a while. They are often a bear to remove intact.
When the turbo starts leaking oil thats the first thing you will notice that there is oil coming out between the hoses and pipes. My f600 had a new radiator new hoses and every thing was clean but it leaked coolant at every connection. I started torquing clamps down to see if it helped.
