Recomended Order for Tightening Exhaust Clamps
Before I begin I did a search to no avail. I originally posted this in another section but I think this is probably the correct place for this question.
I have an 05 F-350 6.0. I just wrapped up some "basic" engine work replacing the STC fitting, cleaning the turbo, Tig welding a cracked bellows on the passenger side up-pipe and removing the EGR scoop on the up-pipe.
This is my first time getting this deep into the engine but I am a mechanical engineer/machinist/fabricator so I have no problems working on machines.
Everything is back together but now I have an exhaust leak coming from the clamp between the turbo inlet and exhaust branch. It doesn't matter how tight I make everything I can't get it to seal.
So here is what I am planning on doing
1. Loosen all the exhaust clamps
2. Loosen the Turbo mounting bolts
3. Tighten the turbo inlet clamp
4. Tighten the two bolt clamp between the pas-side up-pipe and the branch
5. Tighten the EGR clamp
6. Tighten the driver-side manifold clamp
7. Tighten the pas-side manifold clamp
8. Tighten up the turbo mounting bolts
I think in this order I will be able to get everything to seal and it won't be over-constrained.
If there is an error in my logic or a best practice for this procedure can someone educate me?
Thanks in advance.
