hissing noise
I replaced egr cooler and a oil cooler on a 2006 f250 and after I finished I noticed a hissing noise coming from the right rear of the engine, I test drive and also noticed slow response on acceleration. Engine is smooth as silk and not misfiring. When I first start engine for the first 5 seconds hissing noise is not there then I start to hear. Also checked for codes and none present. Any ideas? I'm thinking a leak at one of the turbo flanges but not sure.

The other thing if you really pulled may be a Y-pipe crack.
With a string on a stick and a flashlight you can snoop around all
the connections and not get burned as it heats up to look for a leak.

Check around all the fittings. You may find
that one will be leaking.
When I put everything back on I had both of the
up-pipes loose at the exhaust manifold and installed
the turbo first but left the 3 bolts loose and went on
to the clamps. They slipped right into place without
yanking on them. after I got that all torqued I did the
3 turbo hold down blots and finished up with the up-pipes.
When I started I did not have any leaks.
BTW the shop workbook also says to do it this way.

Awesome, I will reinstall in that order. Now should a get new flange gaskets or reuse the old ones.
