PO301

[Rumblebumble04]

2011 2500 with a 5.7
Got a Po301 code so tried spark plugs then switch coils and checked injectors.
Took off valve cover and confirmed valve on the number 1 cylinder wasn’t moving.
What should be my next step?

If the valve on cylinder 1 is not moving its time for camshaft/lifters you gotta tear the cylinder heads off ect how many miles on the truck?

 

[Rumblebumble04]

330000km it’s Canadian eh lol

rockauto.com would be my friend!
get a 392(6.4L) cam from like a same year charger or something. better performance and are cheaper than the 5.7L cams.
usually will have a plastic timing chain tensioner - try to replace it with a steel one if you can.(while your there anyway)
whether or not you eliminate MDS at this point is up to you.
If you do then youll need the non-MDS lifters, cam and tuner.
If not then youll need the MDS lifters and MDS cam.
I would replace all lifters as these wear together.
youll need a top end gasket set- head gaskets, valve cover gaskets, intake gasket and front cover (timing chain cover) gasket.

I did this to my 2012 5.7 and it ran roughly 600 from rock auto for everything except the tuner because i eliminated the MDS. spent roughly 400 on a tuner to turn off MDS and update the tune.

So roughly 1000 for the whole thing and i did it myself.

Hope this helps

Awesome thanks!

Would I use the 6.4 challenger cam with the 5.7 lifters? Which tuner would I need?

If you're doing the 6.4 non-mds cam (manual transmission cam) you'll want a set of the MDS plugs. Ma Mopar also sells them.

Would I have to change springs and push rods?

Just buy a complete kit from Flying Ryan https://frptuning.com/en-ca/collections/hemi-parts

But with that many miles id get the block inspected before wasting money on a rebuild.

 

[Rumblebumble04]

Ah thanks for the advice
Bought truck off my brother after we found why it ran so poorly
Hoping to get it running properly and get my money back

Tearing this thing apart.
This is what number 1 cylinder and valve looked like

 

[Rumblebumble04]

Why number 1 so clean ?

Why number 1 so clean ?

Blown head gasket probably.Leaks coolant into that cylinder,it doesn't fire and the coolant will eventually wash the carbon deposits away.Might be worth while taking the heads to a machine shop and having them checked over for warpage,and resurfaced if they are warped.

Went threw the lifters and found one noticeably trashed!

 

[EdGs]

If a lifter is trashed, better check the camshaft as well. Also check for metal shavings in the oil control valve, too.

 

[Rumblebumble04]

Found metal on valve
That’s what cam looked like

 

[Rumblebumble04]

Worth rebuilding?

Generally it's reconmended a new engine or a complete rebuild on your existing engine if there's metal on the VVT valve screen.With 330,000 clics you're best bet is probably a complete rebuild or a new engine.
