Hemi 6.4L Lifter Problem

[bjm]

When these hemis have a lifter fail ,many times the needle rollers will fail so the lifter can rotate 180 and basically will operate as a flat tappet.I have seen camshafts worn down until the lobe has almost gone! In severe cases you can not even extract the cam so the motor has to come out anyway! In that case a bucket load of swarf has gone into the motor ! These failures are happening in
all variations of the hemi .!All use the same part numbers .Even late model 5.7 litre Rams inAustralia!Aftermarket lifters ,cams are not solving the problem.
The Chev LS1 is having the same roller lifter problem and there is also a class action re this in the US!

Thankyou everyone for your input! It is crazy that a company continues to sell a motor knowing about the inevitable failure of a crucial part. Unfortunately this is the world we live in today where nobody cares as long as they can get your dollars at the beginning of the interaction. Do they think for a minute that I will buy another Chrysler/Jeep product in the future? They don't care. My biggest regret now is paying the Wanneroo Jeep Stealer $1030.00 today. I will never have anything to do with the "stealer" ever again and will order parts from the USA direct myself. Have had a few shops quote me now. One will replace the camshaft with a "billeted camshaft" (whatever that is) and Trail Hawk lifters for approx $10,000. Other quotes are $8000 for standard lifters and camshafts. Will have to decide if I will keep the vehicle for 2-3yrs (standard replacement parts) or for 5-8yrs ("upgraded" parts). Anyway, will have the car towed on a flatbed from Jeep Wanneroo tomorrow to home / garage and then continue to ring around for prices and advice before deciding what to do. One thing is for sure, I will NEVER buy a Chrysler/Jeep product again!

I am 64yrs old this year. I have now arrived at the point where I hate cars! I grew up with simple motors, no computers and you learned to fix things yourself as you could not afford new cars or mechanics. These days the manufacturers have made sure you cannot fix things yourself and you are subject to their exorbitant costs given computer modules and the like. My younger son has just bought a Tesla Model 3. Beautiful looking car, 8yrs warranty on the car and battery (and 4 yrs on the tyres!). This one dad cannot fix or get involved with - thank God !!!! My wife's GC WK diesel is so complicated my mind just spins. My elder son's SRT...well you've seen what is involved with that one as per above entries. I am now relegated to my motorbike whilst my elder son uses our old Lancer 2005 whilst we work out what to do with the SRT V8. I hate cars now. They are all geared to extract our last dollar to keep them running.

May I add, my brother bought a Holden Sandman panel van back in the day with a 308 V8. In those days, a big V8 would last FOREVER not being stressed at all.....how things have changed...

Feel for ya mate....a LOT of us on here with the same view.
Brand makes no difference.

Just be very carefull of what parts are going to be being put in a rebuilt motor!
1.NB ,If they state that they will use Hellcat lifters used in the Trackhawk Grand Cherokee to stop the problem ,these non mds Mopar lifters are used in ALL hemi motors and still failing.! So they are talking bs.
2.It is the lifters that are failing for whatever reason, so a billet camshaft and
aftermarket lifters does not guarantee any more more longevity than Mopar lifters!
3. Isky Cams in the US ,state after years of research that there is no real
fix for lifter failures !Although they have put out a solid bush lifter that appears to last longer!
4.You are correct in stating that FCA are well aware of these engine failures and are replacing motors in vehicles where owners have put the acid on them!At least
notify Stellantis and ask why are well serviced hemi motors are failing!
The only plus is only up to 20% will fail! Why !

Can only agree with you JD, not only Jeep well I should say now Stellantis it seems most manufacturers are doing the same, a quick look at recall lists will show even the old reliable brands are the same..............

I would be hitting up FCA about it in a big way especially about forking out over a Grand for their dealer to diagnose.
