I've had the GC crd for a week now so it's time to start doing the "necessary" things. Changed the oil, oil filter, fuel filter, did the ehm and machined a plug using the measurements I found on this forum, Thanks! Checked the turbo inlet pipe. I have the orange gasket but it isn't cracked or leaking (yet), everythings pretty clean in there. That's on my to do list. I have been learning as much as I can about the dpf and I'm not liking it so in the near future I'll spring for a tune with the dpf delete and either build a new tube or gut it. Haven't done anything with the swirl motor yet, I'll put in the resistor if I can't caugh up the cash for the tune right away. A lift is coming soon. Still waiting to get my "other" crd (liberty) out of the shop. The more I drive the GC the more I think I'll put the Liberty crd , aka money pit, up for sale. Learning a lot from this forum, many thanks to all who contribute.
