Lifter failure preventions?

[Tuscon]

It is one of the band-aids that does appear to work.Now that there's a few trucks running around with the Hellcat pump,it's not panning out as well as alot of guys were thinking it would. If the whole idea of the hellcat pump is to bump oil pressure at idle,turning the idle rpm up to 700 or 750 accomplishes the same thing,plus throws more oil onto the cam lobes and lifter rollers,helping to keep them lubricated better.

The hellcat pump doesn't increase oil pressure, it moves more oil..."volume". Bumping idle speed won't do that, it will only increase pressure slightly which is not the problem.

You can't move more oil through the same bearing clearances or oil passages with-out also increasing the pressure in those bearings or oil passages. If the hellcat pump is creating 50 psi at 600 rpm,and the stock pump is also creating the same 50 psi at 725 rpm,they're both moving the same amount of oil through the engine. BTW the cam lobe is only oiled via crank splash,there's no oil holes in the lifter roller,it depends on crank splash for lube,and by raising the idle rpm,you are creating more crank splash to lube the cam lobe and lifter roller. The downside to the hellcat pump is the fact guys are seeing upwards of a 100 psi at 3500 rpm and up,which might contribute to bearing wash out,where the oil film is actually passing through the bearings to fast to remove heat from the bearing faces,leading to hotter bearing faces. There was a guy just last night who was reporting pressure issues and codes with his hellcat pump on the hi-po Ram facebook pages.Also there's been a couple of Mopar engine builders who are reconmending sticking with the stock pump,unless you're building a full tilt race engine, where the bearing clearances have been opened up. Most of them are reconmending the mid level Melling pump with the 60 psi spring,in a radical build with bigger then stock bearing clearances.Only Reignited reconmended the hellcat pump,and even he talked about the high pressures it created in the upper rpm range.The old rule of 10 psi per 1,000 rpm still applies,and in excess of 90 psi at 6,000 rpm,well exceeds that rule. It also takes more horsepower to turn the hellcat pump then the stock pump.

You always explain **** better than me.

There are a number of variables that impact the vastly different results from different trucks and people. The two which seem to me to get the least talk-time in the equation are driving habits and maintenance.

2019 Ram 1500 Billet Silver Quad Cab 2WD, 5.7 Hemi, 8HP75, 3.21 axle, 33-gallon fuel tank, factory dual exhaust, 18” wheels. Build date: 3 June 2018. Now at 79480 miles

109,000 misfire cylinder 5 dealer said about $3000 to take apart engine to find this problem had friend look at it and said bad cam shaft Dodge knew this issue but no recall would have cost them a lot of $$$ so owners were stuck with repairs it cost me $1100 for new cam and lifters and now perfect

Mopar filters are wix, see oil filter thread for options. Fram xg2 is a good choice if RP 20-820 cant be bought.

Redline high performance series is a race oil designed for passenger cars. You can see race oils with voa's or uoa's out there, redline uses a stout formula but also keeps the additive levels within reason because of Cats, true race oils are not suitable for passenger vehicles. This formula especially 5w30 kills hemi tick in roughly 80% of the rams that have tried it, not only this latest poll but these numbers helf true for the 6 years prior to polling it, most of those users are long gone, but the votes are public, so they are very precise. These trucks are the worst of the worst, they are already ticking, and yet 80% of the time they go silent with an oil change? Despite this group of ticking hemi's, there was only like one and even that is unverified that needed a new cam/lifters. There were two that did need cam but those trucks had a mis fire first, so no oil can help that, damage was done. Redline gives you the best chance at killing tick and avoiding cam/lifters, most of these trucks also use the royal purple 20-820 oil filter. Best price I see now is 83 bucks per 6 quarts, so it isnt cheap, nothing this good is.

Did redline kill your hemi tick

Redline killed hemi tick - 59 votes
Redline partially killed hemi tick- 26 votes
Redline didn't kill hemi tick - 14 votes

Now, there has always been a desire on the guys responsible for these tests to find other suitable alternatives. Enter lubegard strategy, it is the same science just less of it and results also were less, but much better then w/o this moly strategy.

Did lubegard biotech kill hemi tick

Yes it killed hemi tick -16 votes
Yes it made it better but not 100% -25 votes
No it didnt work -11 votes


So there is a bunch of considerations that goes into these strategies, first and foremost are they safe. Since all of the additives are already used in oil, safe to say yes they are. Furthermore redline has time tested base oils that are also proven safe, in many rams over a decade such as mine and those engines are butter smooth and safe. Also if you followed the oils threads, myself and m,any others cut open filters and did many other things as well, proving these two strategies are 100% safe. There is also a when not to use redline thread, and one of those is in older engines. There is no risk per say, but see that thread for any cons to running this strategy in an older ram.

Many many ram members took part in these tests and tested many other products, these two came out on top, and the results really follow the science. There are other "potential" strategies that show promise, HPL lubricants and Shaeffers are among those, and those also have similar science to the two above. Personally, unless HPL is proven eventually, redlione 5w30 is a no brainer in cam fail prevention, and at a minimum order a case of lubegard biotech 16 ounce and dump it in every oil change, this is the cheaper alternative but may work just as good in a non hemi tick engine, this we don't know. There is also a way to expand redline a bit to help with costs, bg moa can be used as a tbn booster, the new formula with high mag is particularly good. 1/2 through an interval, it buys you a little security and extends interval. If you want to push interval out past 10k miles, it is best to use blackstone oil labs to set your interval.

Most additives are really unsafe, research them before using. Oil thickners and chlorinated parrifins can mess your truck up, just avoid them. Powdered moly is also no good, it gels up in the sump. And most others may not be harmful, but not beneficial either.

what oil pair the best with lubegard biotech?

2014 RAM Loghorn 240k miles all runs well.
I started using full syntethic at around 100k miles I changed full synthetic every 5000-6000 miles
