I know this sounds dumb but how will I know if it’s leaking? Will there be marks? Do I fill it with liquid and see if it leaks? I plan to put air to it to see when it starts moving also. Another thing I’m wondering. Could it possibly be wrong injectors? I put brand new S&S injectors in about 2 years ago. I e only driven MAYBE 3000 miles on them. But I’ve been righting egt problems ever since. Is it remotely possible with a company like S&S that maybe I got late mode 5.9 injectors instead of the 03-04 bowl? I know I’d have to pull one and try to count holes. But has that every happen to anyone that you’ve heard of? They were dropped shipped directly from S&S. Ordered through hardway from a local dealer.
Funny thing that’s commonly overlooked is the thermocouple reading your EGT temp. I checked the temp of my exhaust manifold two days ago on my 12v with a Fluke temp gun after pulling a gross weight of 32k. Temp gun showed 425* at the probe location, EGT gauge showed 300*.
Might do a simple check to rule out the thermocouple or gauge.
What total boost psi will it reach on a decent pull? Empty no trailer
Gotta be a turbo problem. I just went over the whole system with a boost detector and had a shop do the same. Both yielded zero leaks. Well I had one and it’s now fixed but was very VERY small. Either way gasket was replaced on the intake plenum and now zero leaks that I’ve seen since.. I bought the turbo directly from Weston, put a different turbine housing on it to fit a t3 instead of the t4 I got from him and bolted it in. Just because Weston is a bad ass I’m guessing problem lies in the turbine housing. But I can’t figure it out! I’ve wired the gate shut and still no change in boost OR egts..
Or maybe even a possibility of your gate hung wide open, which would be easy to tell if you pulled the housing and looked.
