I figured I would go ahead and get a thread started for what is likely to be a long story.
2009 1500 Laramie - 5.7 EZD series
238,000 miles
Lifetime Powertrain Warranty
Well maintained 5w20 oil changes - a mix of at home and Jiffy Lube joints.
A couple days ago I noticed a new ticking noise. I've had the normal exhaust leak for quite a while and have pretty much given up on that ever being completely fixed. I've had the bolts replaced by the dealer 2 or 3 times.
The other day I got a check engine light which presented P0304 - Cylinder #4 misfire. I was due for plugs anyway, so that was my first step. No change. Swapped #2 and #4 coil pack. No change. Swapped #2 and #4 injector. No Change. Compression on #2 and #4 were both around 180. Leakdown test showed no meaningful difference in 2 and 4.
I decided it was time to pull the valve cover. Springs looked good, rockers looked good, rods looked good. No slack in the rods on #4.
After some google work I found out about the seized lifter issue. Back to the garage with camera in hand this is what I found -
I went to the local dealer to chat with them about the coverage under the Lifetime Warranty. The service writer said there is nothing at all they can comment on, speculate about, or even talk with FCA about until they diagnose the issue. I showed her the above video and suggested that it was likely a problem the mechanics were familiar with and that there really wasn't any diagnosis that need to be done to begin the conversation about the warranty. She insisted that the diagnosis was the required first step and that it was a week before they could get me in to take a look at it.
So the truck sat for a week waiting on my appointment.
I took it in this morning to drop it off. The new service writer asked what brought me in today. I explained the situation and got a kinda blank stare back. He finally responds "So you want a ... cam and a ... lift kit?"
I explained it all again and showed him the video. The ticket he entered said "Replace cam lifter and cylinder #4" He said that should be all they needed. They would take care of everything and have have it ready for me this afternoon by 5.
Somehow, I doubt this is going to be a fun experience. I'll keep you all up to date.
