Oil Jet Bolt Inspection

WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.

Remove the oil jet bolt (see OIL JET REPLACEMENT ).
Inspect the oil jet bolt as follows.
- Make sure that a 0.6 mm (1/64 in) diameter drill bit will go through the oil intake (0.7 mm (0.03 in) diameter). Make sure the check ball (A) moves smoothly and has a stroke of about 4.0 mm (0.16 in).
- Check the oil jet bolt operation with an air nozzle. It should take at least 120 kPa (1.2 kgf/cm, 17 psi) to unseat the check ball.
