Timing Chain Guide Advise
 

While I have things opened up I am staring at the timing chain tensioner guides. They have a bit of wear. The flat guides have a groove with a max depth measured at .004". The tensioner guides have a groove with a max depth measured at .041". The wear is mostly at the end where it looks like the chain deflects the most. Should I replace these, or is this acceptable wear? Motor has 118k miles.

Looks like I would need to remove the oil pump housing to extract the bolts that hold the guides on the front of the motor.

since you're that far in, I would absolutely replace them.

When you remove the oil pump, replace the cast pump drive shaft with LN Engineering's chrome moly steel upgrade. Cheap insurance.

Parts on order. Thanks for the replies.
