I know its dirty under the hood.

Learn something new everyday,lol. I did not know the 6.4's used a maf sensor.Thanks for the picture White,muchly appreciated.

@Wild one you May be right, I’m starting to think my truck doesn’t have a MAF sensor, even though ones listed for it at RA as well as all the Mopar sites. However on the Mopar sites it states it’s also referred to as other names. I’m just sitting in the parking lot of grocery store now so I will post some more specific information later. @White six four what engine is on your truck?

If that's the only sensor in your airbox and intake tube, you don't have one Burt.
Wonder if the early built 16's used one and the later built 16's did away with it.
I know they only used a maf sensor on the early 15/16 Hellcats then they did away with it.
That's all i got,lol

 

[BurtShaver]

That seems to be it, just the 2

Oh, just a little fun fact, this morning I went down to have a look at the air box. The hood had a fair amount of snow and ice that I couldn’t bang off easily so I got as much off as I could and raised the hood. I’m looking at the air box and the hood closes on my hand, it came down hard, luckily it hit in such a way that my hand didn’t get broken or hurt at all actually, at first I didn’t think I was going to be able to get my hand out and somehow I wasn’t able to get to the release to open the hood, thought i was stuck there till someone drove down the lane way but because of the thick insulated work gloves I was able to slide my hand out of the glove

On the mopar website for the maf it lists it for 14-16 rams with the 6.4 so maybe the later 16s didn't get it.? Next time I'm outside I'll run out to the shed and check the build date on my truck. If I remember correctly my uncles 14 3500 with the 6.4 was the same as mine. Only looked under his hood once though when I replaced the map sensor on it last spring.

Maybe your truck doesn't want you to fix it. Just wants to hibernate til spring lol. I'm glad you were able to get your hand out of there. That could have been bad.

Thanks @White six four . Yes, that could have ended up very bad. I find the older I get, I’m doing those kind of things more and more lol. I may have to hire someone to follow me around just to keep me out of harms way. On a side note, I’ve picked up a Haynes manual from Canadian Tire and to my surprise the manual is quite detailed. I tried to make plans to tow the truck to my great grandfathers garage that my uncle now owns but uncle was away today at Xmas party so I’ve made plans to tow the truck over Sunday, then going to get to work at getting a wood Stove in there, so it’s a slow process, but I certainly do appreciate all you guys answering all my noob questions. Once I get it in there and get some heat, the first thing I’m doing is getting the valve cover off to see what I see. Either way, I need it inside with some heat because I don’t enjoy working out in the cold or dampness. In the meantime I’ve been reading through this Haynes manual, I’m hoping someone will please tell me I don’t have to drop the oil pan on this to get the oil pump off? Because according to this manual for 4x4 models It looks like a PITA. I can’t remember exactly where but I’m sure I seen a video or a thread on here where the timing chain tensioner was removed or tension taken off, and the oil pump was left on with the timing chain?

 

[Wild one]

That's all i can come up is maybe a later built 16 did away with the maf sensor.Maybe Burt will get his build date for his off his door to compare to yours White.
I can't see any differance between a US spec truck and a Canadian spec truck, maybe it's a factor,doubtful but who knows.

Read through Kurtis's thread,he has pic's of how we used Zip Ties to hold my timing chain in place when we did the cam on my truck.Another trick is to use a piece of welding wire or a straightened out coat hanger laid across the rocker stands to hold the pushrods in alignment when you re-install the rocker shafts.
The oil pump is removable but you'll want to bend and tweak a cheap 13mm wrench to get at the bolt on the pick-up tube.If you're truck is still making good oil pressure,i'd leave the pump in place,as they aren't really a high wear item.

How-To: 4th gen hemi cam installation

Since cams are becoming more available for the VVT hemi engine, regardless of whose cam you choose, here is the how-to of doing the cam swap for the 4th gen trucks. This is honestly a job that can be done by anyone with basic handtools and basic mechanical skills. I did my first cam swap...

That would make it a later built 16 then,as production of the 17's would of started only a few months after that

Oh good, that was worrying me, there was a lot of work involved to get the oil pan off, so IF I do end up needing to replace the cam and lifters I will do it with the oil pump on. I thought I read that whole thread you sent but I will read it again. Without reading it, I’m thinking something along the lines of zip ties around the timing chain to ensure it can’t move/skip a tooth on the crank sprocket. But your saying that the oil pump can be removed without removing the oil pan?

His pictures starting in post #4 are from my trucks cam install,and show how we just tied the chain up so it couldn't fall off the lower sprocket.
The pump is removable,but you'll probably use all the curse words getting it off with the oil pan still in place,lol.
If you do remove it,you might as well put a new one on.The 6.4's utilize piston squirters and the high volumn hellcat or melling pump does benefit them more then it does on a 5.7,as the squirters are basically an internal oil leak

Thank you, I was getting a little stressed but I’m feeling better about it now. Actually looking forward to this

Allow yourself lots of time,and take your time,it's the guys who try to rush through the job that have issues.
Mark the heads so you don't mix them up,and pay close attention to the head gaskets as there's a right and left gasket,and top to the gaskets. Sometimes it helps to compare the head gaskets to the ones originally installed so you don't mix them up

Yep mine must be an early 16. Build date 7-15

16 was when they started to go away from the MAF sensor on the Hellcats,the later built 16 Hellcats didn't use a Maf,but the 15's and early built 16's did use one.I'm guessing it was the same on the truck 6.4's too

 

[BurtShaver]

I just got finished the link you sent, I must not have made it all the way through the first time I read it. Glad to see that I can simply mark the timing chain and cam phaser (hope I got that term right lol) keep the chain tight in the crank and everything will stay in time. When I’m taking the heads off, the Haynes manual shows to remove the exhaust manifolds from the head but I think I’ve seen posts or video’s where they have removed the heads with the exhaust manifolds still attached? Is that possible to do? Would you recommend new head bolts? The link says if your on a budget you can reuse them? I’m not wealthy but if they should be replaced I will replace them but I’m also thrifty so if they are good I will re use them? I guess the thinking is the threads get stretched a bit ?
