Supersession Statement
This PI was superseded to update model years. Please discard PIP5216E.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition / Concern
If a vehicle comes into the dealership with a knock noise, seized engine, lower end squeak or squeal or any condition that you
suspect a rod or main bearing failure.
NOTE: THIS PI ONLY REFERS TO CRANKSHAFT BEARING DAMAGE DEBRIS.
First, verify there is metal in the engine oil caused by BEARING DAMAGE / debris by removing the oil pan.

If Due To BEARING FAILURE when completing diagnosis, and deciding whether to replace the engine or repair it, complete the
following before making that determination.

Recommendations / Instructions
1) Inspect the oil control solenoids for metal debris. This shows the oil filter is in by-pass and unfiltered oil with bearing debris was
pumped into the oil lubrication gallies, throughout the engine

2) Inspect for damage to the cam caps Journals and camshaft journals on the heads (obvious signs of metal through the cap).

3) Inspect the timing chain idler sprockets for stiffness when turning. ( Should turn smooth and free)

Any Of These 3 instances would be cause to replace the engine instead of repair.
While engine replacement at this point will be necessary, additional inspections should also be made for:
a) Sludging caused by lack of maintenance. See the latest version of TSB 16-NA-222.

b) Global oil starvation caused by running the engine very low on oil.
c) Intentional abuse to the engine.
If these conditions exist, warranty could be declined or feedback made on WPC inspection.
Maintenance documentation should be obtained in these instances for warranty validation.
NOTE: If this is the case, then a call to TAC is NOT required prior to engine replacement.
At this point you should clearly document your findings on your repair order, fill out the cost worksheet, and call PQC only if required
for your dealer.
Keep in mind that a repair and then replacement will usually be cause for additional inspection and scrutiny that could result in more
questioning about the repair methods.
HFV6 engines are scheduled to be returned to the WPC for inspection to verify the concern, as well as the information provided in the
repair order to support the engine replacement.
