I picked up a 2011 Ram 1500 at an internet auction. I have read enough of these posts to realize this is a cronick hemi problem. However there is no tick at all. Even with a stethoscope all I can pick up is the injectors cycling. I went through the whole dance like everyone else with plugs and coils ect. and finally pulled the valve cover. I have noticed that in all the other videos I have seen the valves at least move a small amount but my #1 valve spring (it throws a P0301 code) doesn't move at all.....zero. I was hoping to get lucky and have it be a broken valve spring.... but no. My question is....is it possible for it to be the MDS lifter is bad on the #1 cylinder and won't lift the push rod at all? Like I said there is zero valve movement when cranked. Also when driving it it really bucks when the torque converter locks up under light throttle.......seems like it is more than one cylinder would do......back off and step on it harder and it seems to smooth out? Wondering if this could be a MDS system malfunction. One last thing, and I'm not sure if it is related, when I let off gas like coming off the Interstate and coast to slow down....when I go to pick up the gas again sometimes I have to keep pushing the throttle down to maybe half throttle with no response and then it will catch and take off hard? Hope someone has seen this before TIA
