The bellows are the accordion looking pieces right? They look fine from what I see. I dont see any soot from where they would be leaking. What else should I look for with the up pipes?
Its a port and polished ihi I built this past winter with a wetzel wheel. Everything was dont the way it was supposed to be. I even had the internals balanced. Its been a great turbo and haven't had any issues until now. I havent had any time this evening to look much. I made the tool to do the leak test. Hooked air up through the intake horn and found a leak at the outlet of turbo hot ic rubber. Fixed that leak. (Small) Also had another leak cold side intercooler to ic pipe rubber (even smaller) fixed it. Tested it a few more time and didnt find any more leaks. I unhooked the waste gate and made sure the lever was closing all the way. Only thing I haven't done is check axial play haven't had time. I will go check it right now wont take a few minutes.
It feels like the turbo is falling under the fuel at mid to top end. Hard to explain. It smokes more than usual. Now that I think about it it hasnt boosted to 28 since the turbo bark. The gauge is a autolite II. Hose seems alright.
Brian, Where would you suggest I start looking? Like to get some ideas going for this weekend, will not have time during the week. 12 hr shifts 2 month old...dont have much time during the week.
