i own a 05 lly just blew the head gaskets. not sure to put a new motor or get a uaed one or just rebuild it? Ive owned the truck for a year its been great till now. What are the common probles with a LLY motor?
If you are mechanically inclined you should be able to do the headgasket repair yourself. Just beef up the components this time.The most common problems with LLY's are the headgaskets believe it or not. There is also occasionally an overheating issue if you tow heavy, but i wouldn't so much worry about that.
I did my head gaskets about a month ago and used the kit from merchant automotive. It came with ARP studs, grade c head gaskets, and all the other gaskets you need. Its not a very hard job, just alot of work. I did the job in my driveway. I agree with jc1843, definitely no reason to rebuild the whole motor unless theres other damage.
LBZ mouth piece or an AFE one. I have a 2005 Kodiak and all the parts I have tried to either order or put onto my LLY don't match or fit. Does anyone have any info on the difference between the engine in the kodiak compared to an engine in a HD2500?
