Well, my 2013 5.7 hemi has a rounded cam lobe. What are your thoughts? Install a new cam and lifters or a whole new engine? The old one has 134,000 miles and was running great until this issue started. #7 misfire code. New plugs and coil didn't fix. If a new engine is installed we're looking at a $12,500 bill! I can order a long block for about $4000+ and pay install labor. Or a new cam and lifters for about $1000 in parts and I do the install myself. But I am still running an aging engine that has an oil issue that starved the cam lobe. What say you all?

If you are going with a cam and lifters, change the oi pump as well. also check the oil galleries for sludge. If it has any buildup of sludge, clean the oil galleries. I've seen a buildup on a couple of engines now. I would not do a cam replacement with the engine in the truck rather out on a stand where it can be properly worked on.

Who told you the cam lobe was worn? Just courious.

If true, installing a new cam and lifters is not going to last very long unless you find out WHY the lobe wore down. Ooiling issue on....one.....cam lobe? Not probable. If oil pressure was the issue, all of them would be worn down, along with your engine bearings, all of your lifters and your check engine light would not just be on, it would be flashing for critical error.

Buy a rebuilt long block. Then you do not have to find WHY that ONE cam lobe was worn down. The cam lobe is the result of a problem that is not just oil on that one part. And if oil is a problem, your bearings are toast too.

If you have been running it for a year with it ticking and throwing codes Ill bet your VVT solenoid screen is full of metal shavings. My 5.7 had to have the cam and lifters replaced at 138000 earlier this year. I took it in as soon as I heard the ticking and before it threw any codes.

I recently went down this path on my 6.4. With valve job machine work, new intake valves and valve springs, new Mopar cam and lifters, new oil pump timing chain etc, the parts and machine shop bill was about $4000. Rock Auto reputable US brands and the discount Mopar guy on this site. And about 40 hours of my time.

I chose this route because my 2015 truck with a dropped valve wouldn't be worth much and any used truck i replaced it with would be another unknown. Now I have a 'known good' top end. And the truck isn't my only vehicle so I could have it down for a while working on it at a reasonable pace.

Same year/motor. Similar issue at about the same mileage. Was quoted ~$5k for complete cam/valve job or $8k for a new motor replacement (short long block) with a 3year/100k warrantee. For me it was a no brainer and went ahead with the new engine.

Edit: sorry, long block. Lol

Where did you order it from, and is it a Mopar rebuild or aftermarket?
Thanks

Here’s a vote for the cam and lifters rebuild route. Check the VVT solenoid to ensure no major metal filings. Do the routine maintenance items while you’re in there.

There are many 5.7 engines well into the 300k range.

With the new parts and better oiling strategy, my bet is that the engine will make it there.

If I could rewind time I would have gone non MDS with simple pcm reflash. I may still do it.

P.s. I also look at the new engine like this… are you willing to pay $12,500 for an engine that still has the same inherent flaw? $2k for me to get another 100k from a paid off vehicle was worth the gamble… $12k? I would have bought a different truck.

Again just my opinion.

Best of luck in your decision making.

Why doesn't Ram fix the tick?

Simple, money.

 

[Shawn Burns]

I will replace cam, lifters, and do the mds delete if my cam goes.

 

[Hagar1]

Simple, money.

Yup! It is cheaper in the long run to pay for a bit of warranty on the early failures than it is to do any re-engineering!
That is what it boils down to is money.

What about all the cam particulates that have been floating around that engine for years now guys? Is it any problem there?

If the VVT screen is full of metal filings,it's usually reconmended to replace the engine,if the VVT screen is still semi clean,then you can get away with just replacing the cam and lifters,and doing a couple short oil and filter changes afterwards.

I’m jealous,it is harder to justify all the top end upgrades that would nice to do,but you should do a complete build.I can’t get the thought of a hellcat oil pump with the oe spring upgrade .Dont forget the limitations of the 8 hp70.Still don’t want the new 3L six twin turbo.
