Exhaust Fumes

Perform the following steps for Exhaust Fumes.
1. Visually inspect the exhaust system for leaks (e.g. exhaust manifold, S-pipe, and
turbocharger).

2. Tighten all S-pipe clamps to the proper torque specification.
3. Reprogram the ECM.

Slobbering

Perform the following steps for Slobbering.
1. Visually inspect the entire length of the breather tube for kinks.
[a] If the breather tube is damaged, repair as necessary.
[b] If the breather tube is not damaged, perform step 2.

[b] If the oil dipstick marking was correct, testing is complete.

Engine Vibration

Perform the following steps for Engine Vibration.
1. Using a 0.060 in. feeler gage, measure the clearance between the bottom of the steel
engine mount and the rubber biscuit at the rear engine chassis mounts.
[a] If the engine mount clearance is less than 0.060 in., replace the mount.
[b] If the engine mount clearance is greater than 0.060 in., testing is complete.
