Has anyone ever had to change their cam shaft and lifters?
I have a 2014, lifter cam replaced under warranty at 54000 miles. Valve seat dropped broken valve and piston in oil pan at 145,000 miles. the warranty cam and lifters were fine when i took it apart. but i needed a new engine anyway. Bought a new 6.4 hemi crate engine from mopar, after 250 miles it was knocking ....... yeah, you read it right. I tried to get it warrantied, but the dealer wanted $3700 to remove and diagnose it.. i told them to go somewhere else. i took the new engine apart, again valve seat issues.. yes new engine !!! i took the heads to the machine shop and had them reseated by a professional (obviously not chrysler), put in a stage 3 cam, hardened rods, and racing springs with greene racing for the tune, been a trooper ever since. I WILL NEVER BUY ANOTHER CHRYSLER PRODUCT. the new engine was mfg in January of 2020 and had new style/hell cat lifters in it. I also did an MDS delete. after all this I get about .75mpg less and must be pushing 600hpRe 6.4 / 392 Jeep SRT engines - Can any one advise if the problem of lifters failing (way before they should) been rectified in later models? If so from what year on is OK? I can't find anything in the forums about this, but lots of tales of expensive repairs. I understand there were revised...www.cherokeesrt8.com
