Recipe - Ram ProMaster 3.6L Pentastar V6 (2014-2025)

Specific Fix build

Reliability tier: aggregated - verify before ordering, see /disclosure/

The 'Pentastar tick' path: compression/leak-down first (rule out the pre-ProMaster 2011-2013 head issue and exhaust leaks), then rockers and lash adjusters, cam replacement only where a lobe is damaged.

Parts

• 3.6 Pentastar Rocker Arm (5184296AH, current) - the tick item per cylinder (qty 1)
• 3.6 Pentastar Hydraulic Lash Adjuster (5184332AA) - replace with the rocker (qty 1)
• 3.6 Pentastar Camshaft, intake (68172837AA) - advanced cases with a damaged lobe (qty 1)

Install order

1. locate the tick per cylinder (hose/stethoscope); rule out exhaust leaks
2. compression and leak-down before opening the valvetrain
3. valve cover off: inspect rockers, lash adjusters and the cam lobe at the suspect cylinder
4. rocker + lash adjuster replacement (pair, never one alone)
5. cam replacement where the lobe is damaged

Expected outcome

Tick gone; compression holds across cylinders.
