Checked out the rig yesterday, no broken manifold bolts. We put it on the hoist, there is more smudge on the tail pipe than I expected and he asked if it was running rich or throwing CEL, no to the above. There are no slip joints/clamps, only welded pipe and bolt flange connections. Only "leak" we saw is the weep hole in the muffler, it is smudged also.
Is there an air inlet somewhere in the back?
Most vehicles draw fresh air from the cowl and this one would have exit vents in the D pillars.
There is no tears in the weather stripping around the lift-gate or back window.
We put a new cabin air filter in...
I did ask what that gizmo is next to the fuel tank and was told it is the charcol canister, under the vehicle?
He asked if I was sure it was exhaust I smelled and not fuel...
