2006 300c awd camshaft and lifter failure in a 5.7 hemi

0 for start up pump ability. 30 for heat.
 
where did straight aything idea come from?
no straight 30
well you could pre heat it
but to thick for start up evebn in south arizona
 
I would think that pressure fed HR lifters would solve the problem
who makes them?
 
I don't know where you got the "new" engine or if it was a just an original running motor you found, but while your taking it apart and spending more money on it I'd stake the valve seats if your planning on keeping it! I just had my 05 drop a valve seat and the car isn't abused and never overheated!I put a scope in number 7 and the piston doesn't look bad but I can see debris in there! won't know until I get the head off if it needs a piston or cylinder damaged. I know it will need a head! just over 100,000miles and first problem ever!the car could use a new front cradle so I'm going to look at a partout car today,hopefully the cradle and drivers side head is good!
I was looking at a paxton kit for it a guy had for sale a couple months ago. I know I would have blamed the failure on the blower had I installed it but now I'm wiser!

This engine was bought new thru a chrysler dealership and warranty expire a month after. So chrysler said not helping you out because of the expired warranty. This engine only has 28,000 miles on it. I did oil changes at 3,000 miles. The first shop told me it has bad lifters. I talked to Mike at HP motors in NJ. He told me its in the bottom end of the motor after he told me to take off the coil wires of each cylinder one at a time to see if it got louder or quieter, well cylinder 3 got louder he thinks its a wrist pin. To make sure I have to bring him to car.
 
I'd keep hounding warranty dept. on this one,squeeky wheel get's the grease!My friend just got a check from them after pestering them for 2 years over a jeep trans. Helps that he's a pitbull lawyer like a dog with a bone!
 
talk with the zone rep that used to be me I would have helped you out
especially if you have any info of any problem prior to warranty date or you had a delayed intall
you are not an expert and did not recognise the problem...

Best thing to do is get a few vertical lines in the lifter bores, now you’ll have oil on the lobes.

Wouldn't be the first time he's been wrong....and he's wrong a lot.
I've beat all (3) of my 5.7 hemi's (one non-MDS, two with it) like rented mules and have had zero issues.
I always use Mobil1 in the exact weight Dodge calls for on each vehicle (yes, they're different), no exceptions.
 
Early Gen 3 semi hemi had valve seat problems. Somewhat common. Corrected on later models as I understand.
 
With piston squirters on 6.1’s, I’d suspect that a squirter could be made that sprayed the bottom of the cam to get that splash oiling going.

A little beating keeps them healthy.

My Ram is an '04. Nary a worry.... 175k miles and is used as a truck.
 
Exactly. I worked with a guy who went through two of them in a short time period.

Original engine went at 139,000 and with oil changes at 3,000 miles because I had lifetime oil changes. The second one was bought thru chrysler
with the same 3,000 mile oil changes using synthetic oil went at 28,000 miles and a month after 3yr warranty expired. So Mike at HP motors is looking
for an engine out of a crashed car.
