Well, I have been noticing an exhaust leak lately. It became even more noticeable while towing my new 29ft camper trailer. I crawled under the truck and began my inspection. My first through was probably the up pipe donuts, but there was no soot at all. Finally I found that a head had broken off one of the manifold bolts on the driver's side. The good news is it should be easy to get at once I get the manifold off. The bad new is I still have to fix it. How much power am I losing by having this type of leak. I would imagine that the leak is pretty substantial, it is really loud under load and there is a lot of soot on my tranny and tunnel.
Being as the up pipes are in good shape and not leaking, but I will still have to remove them I was going to just replace the hardware and install the larger Chevy donuts. I really cant justify $800 for bellowed pipes unless they can be found way cheaper, these are still in good shape after 235K miles.
For the manifolds, I cant decide if I should buy new ones or have these surfaced. If there were some sort of performance increase to be had I would consider something different. I would love to get ceramic coated ones or send mine to Jet Hot to have everything coated. I was quoted $355 for manifolds, up pipes, and turbine housing in Extreme 2000.
Other things I plan to do while I have everything out is gut the EBPV
, check turbo tolerances and rebuild if needed or purchase turbo, replace orings, CCV
mod. Is there anything else you guys would suggest. Maybe a 1.00 turbine housing?
I found this turbo Click
I would like to get as much power/efficiency as possible using the stock injectors and stock/modified turbo. I found a guy that sells My truck is used for daily driving and towing a camper that is 6000 lbs loaded. Thanks for the input.
