So yesterday I put a new cac boot on. Took it out and after a couple high boost runs something sounded like a boot blew off. I checked and all boots seem fine. Now I'm throwing codes p0480 and p 0528. I just went on a 30min drive and my EOT reached 221, ECT 218, and TFT 191. Also my turbo seems really loud and doesn't sound right but is making boost just fine. What do y'all think this is???
Also it could also be a boost or exhaust leak (the pop sound not the code)
With the truck cold (overnight is best) have someone power brake the truck. Look for black smoke, that means exhaust leak. Also feel and listen for boost leaks. Either of those can cause higher temps.
Just found that the fan cut the wires running to the clutch. What a stupid design with it being so close! Well I fixed that. The turbo sounds weird still, it's really deep. I think I might have blew the clamp loose on the exhaust manifold side of turbo. It looks fine but I can't think of what eles it could be. Sounds like it's coming from right by the firewall
Yup. I took a closer look tonight and I can see a soot footprint around where the downpipe bolts up. I do believe I found the problem. Odd for that clamp to blow loose and the fan wires to get cut at the exact same time. But hell, I'll take those easy fixes any day
If it's building boost fine I can't imagine it would be a very significant leak, but them again it doesn't take much, I'd check out the bellows as well.
