Common Jeep Engine Issues
These are the most frequent reasons Jeep owners need a replacement engine.
3.6L Pentastar — Rocker Arm & Cylinder Head Crack: The 2011–2013 Pentastar in Grand Cherokees and Wranglers had the original rocker arm design prone to failure. Additionally, some 2011–2013 units developed cylinder head cracks at the #2 or #4 exhaust ports. Both issues were resolved in the 2014+ revision, making replacement with a verified-year unit the smart move for early Pentastar Jeeps.
3.8L V6 — Typical Chrysler 3.8 Issues: The 3.8L in the 2007–2011 Wrangler JK was never considered a strong engine for the Wrangler's weight and use case. Oil consumption, valve cover leaks, and general lack of power plagued the platform. Many JK owners replace the 3.8L after it develops oil consumption rather than rebuild a platform they were never happy with.
2.4L Tigershark — Same Issues as Dodge/Chrysler Applications: The 2.4L in the 2014–2022 Cherokee and Compass shares the Multiair actuator and oil consumption issues found across all Stellantis applications of this engine. Replacement is common at 80K–120K miles.

Jeep Engine — Quick Answers
Do you carry the Jeep 4.0 inline-six engine?
Yes — the 4.0L AMC/Chrysler inline-six remains one of our most popular Jeep engines. We stock units from TJ Wranglers, XJ Cherokees, and ZJ/WJ Grand Cherokees. Due to the age of these vehicles, low-mileage units command premium availability — request a quote early.
Will a Pentastar 3.6 from a Grand Cherokee work in my Wrangler?
The Pentastar 3.6L uses the same base engine across all Jeep applications, but the accessory drives, motor mounts, and wiring harness connections differ between models. We match the engine to your specific vehicle and model year to ensure a direct bolt-in fitment.
Can I put a HEMI in my Wrangler?
We sell OEM replacement engines that match your vehicle factory specification. If your Wrangler came with a Pentastar V6 or 2.0T, that is what we source for you. HEMI swaps into Wranglers are custom builds that require extensive modification beyond an engine replacement.
How long do Jeep Pentastar engines last?
The 2014+ revised Pentastar 3.6L is a proven long-life engine when maintained properly. With the rocker arm and head issues resolved from the early production years, these engines routinely reach 200K+ miles. Our replacement units in the 45K-65K mile range have the majority of their service life ahead of them.
