One thing that I did with my 12 when it started ticking was I immediately dumped sea foam in the crank case drove it on the freeway for 100 miles never going faster then 60 mph. I already had my oil change ready to go. I switched from Mobil 1 and a wix I believe is what I was using at the time. I went with Castrol edge 5w30 and a puraltor boss filter. That solved my issue. I also just started running lube tech bio guard in mine. I have gone 4 years and the tick has never returned.So I have a 2012 Ram 1500 sport crew cab with a 5.7 hemi. I have replaced 2 sets of manifold bolts, one as recently as last Sept/2020. My motor has recently started ticking and I’ve had 3 mechanics tell me it’s internal. I’ve been obsessing about this for a couple weeks, the motor runs so smooth on the road and highway it’s hard to believe it’s a lifter problem eating my cam. I’ve run synthetic in this thing for as long as I e had it 5w20. I ran into money struggles during covid last year and let my oil changes go longer than I normally would do it’s probably my fault this is happening. I just put 1 quart of Lucas synthetic oil stabilizer in my motor to try to quiet it but so far no luck. My local mechanic did my oil change 2 weeks ago but he used an oil called Motosel synthetic 5w20 that I’ve never heard of and a really cheap oil filter, it’s label says “certified” across it so it’s some no one name brand he charged me 100 for this change. I can order redline 5w30 from Amazon here in Calgary Canada and wix dp oil filters there too or a Napa one. I’ve peice the came and lifter job out up here but it will cost 5-6000 dollars to fix it. How serious is this problem and how long will this motor last managing this tick with oil? Thanks in advance for your help. By the way I don’t usually use this mechanic for my oil, I was trying to save cash but for almost the entire time I had the truck I took it to the dealer which ran penzoil 5w20, even jiffy lube ran that for synthetic yet this is still happening to me. I can’t afford a 14,000 new motor for this thing, even the cam and lifter job at 6k will break me. I’m a single income dad supporting my spouse and daughter and am by no means a rich man. I was hoping this truck would last the 350-400k so I didn’t have to keep soaking money into vehicles but this truck is becoming a money pit.
