2010 Dodge Ram cylinder 1 misfire p0301. Video attached

[StephenM]

I’ve posted on here about a misfire in cylinder 1. P0301. Won’t rev above 4000 rpm while driving. Rough idle

I took some videos today of after I pulled the valve cover and noticed cylinder 1 had 0 lift. It would lift fine it seemed at the beginning of the crank then just stop all together. Can anyone help me with this

I thought it may beeen the cam and lifters

What oil have you been using?

Usually if there is no other codes, that is nearly 100% of the time a cam lob was wiped. Here is the cam bible thread around here. Known issue.

Why it might lift at first? When oil is cold, it is very thick, it could literally add enough film to raise the lifter once or even a few times.

It does have old oil, it sat for approx two years. I just purchased it a few weeks ago

I was thinking cam was wiped also but would that cause it to lift when first starting then completely go dead and not move at all

It is for sure possible if the cam lob or lifter bottom has oil on it. But it literally would lift it once or a couple times possibly and then wont be able to as the oil is either wiped away or heated up. I could lead you down a direction that could test it, but then you would just be putting **** in your engine that don't need to be there. Best move swap coil and plugs make sure code stays on c1, and then writing is on the wall. See what condition plugs are in. If you have a boro go scope it and maybe another cylinder.

yeah cylinder 1 has a new injector and also I’ve swapped coils to confirm it’s good and used a tester to make sure it’s firing. Plugs are brand new. I’m ghnna change the oil anyway so any advice would be great

I’m just stumped as the lifter lifts then it just completely collapses and doesn’t move at all

I appreciate the help

I wouldn't add an oil thickner, but if you did the lifter would likely lift a couple times before it stopped. Lucas stabilizer the non synthetic one is an example of an oil thickner. But, if one lifter aint lifting, there is only one cause the cam isn't lifting it. It is easily the number one mechanical issue on this board. I really wouldn't use an oil thickner if you are planning on fixing it.

We have had examples on this board that this can sometimes show up gradually, and then those codes were thrown when the oil was hot, they tended to happen when oil is hot. Not every time, but enough to understand what happened. If the cam was slowly worn to the nub, it makes sense the code would be thrown first when the oil was hot, as in there is a very thin layer on the cam lob due to temperature. In those trucks the next day they would start and run to grocery store or something and have no issues. But soon as oil got hot again the mis fire happened. The cam was still hitting the lob but lifting it less high. Eventually they all needed cams, and not much longer after the mis fire happens. This didnt happen every time, but it happened enough, the fluid friction of cold oil will lift the lifter. But even then it is just a manner of time before is misfires completely, not much time either. Read that cam thread, pay attention to the rod installation and length and timing, that is the number one issue with cam installs. The average dealer charged over 5 g's for this, the average shop charges over 3 grand for this cam/lifters. It is doable one step at a time.
