Want to share my saga in replacing the rockers on my 2015 Grand Caravan, so that others may avoid making the same mistake.
Basically, I wasn’t aware that third gen pentastars have a different rocker arm profile.
I ordered my parts from eBay, the seller claimed they were OEM and were the latest 5184296AH. Should’ve gone the Rockauto route or like I eventually did, a Mopar online store.
After installation the engine started a bit shaky and then died. Then it would be hard to start and once started there random misfires code P0300. There was a very strong smell of gas.
Immediately I thought it jumped timing and I missed it somehow. I dissembled everything for the second time only to find the timing marks how they should be.
After much research online I finally came across someone with the same symptoms as me and they had wrong rockers. I checked and sure enough, the eBay rockers were way different.
Left is the OEM rocker and right is the eBay one. It clearly has a lot more lift and the valves were not closing fully.
I ordered new rockers and everything is fine now, but this job was nerve wrecking all the way till the end. It was a big relief when the engine fired up properly.
