Maximize 3.6 Reliability

[Wicked_JL]

This thread derailed pretty bad ? I will help OP with an idea!

So for me (i am going to become a 3.6 V6 owner soon if all goes as planned) it looks like the number one thing this engine needs is proper lubrication

Others have chimed in about the oil change interval but i do not think that is the problem.. I
I think the issue is that this engine dumbs the oil back into the pan every time you turn it off

Which is why they make the following mod to stop it from doing that!

To me this would probably be my first mod to keep the engine lubricated 100% of the time

I’m still researching “walnut blast”. Sounds kinky.

I’m still researching “keep the lubrication going all the time.” Also kinky. ?

I have the same engine for the same reason with the same goal. Almost every time I pull the Jeep in the garage, especially in warmer weather, I open the hood. My reasoning is the faster all the built up heat dissipates, the longer all the rubber, plastic and electronic components will last. Red Line hood struts make this easy and enjoyable. And because I'm seeing my engine frequently I'm paying attention to what I see. Top tier gas and religiously changing my oil-myself-with OEM filters, at least every 4K miles added to the above. I'm also easy on the skinny pedal and don't red-line it, but not afraid to work it hard when needed. It's the little things over time that make the difference.

I thought walnut blasting wasn’t necessary on the 3.6 because the non direction injection cleaned the backside of the valves. I think the 4cyl does need it every 30k though

FWIW: I haven't heard of anyone getting this done on the 2.0.

The best way to make any engine reliable is to look at those that have failed. Lifters/rocker arms, head gaskets, flywheel (for MT)...

My reasoning is the faster all the built up heat dissipates, the longer all the rubber, plastic and electronic components will last.

Just don't cool it too fast. There is such a thing as thermal shock... "rapid temperature changes greater than 15°C/minute"

I change the oil every 4k miles and do the ol'Italian tune up periodically. Runs like a top.

Yeah. Cop car engines last ages. Basically long running periods, regular oil changes etc.
Moisture in the oil isnt good. A warm dry engine means less cold start wear, which is where most of the engine wear occurs. Arguably stop/start isnt good for engine life. You could disable stop/start.

Dont be scared of rpm's and engine braking as well.

No garage queens. Ride her often and hard

I have been driving the 3.6 since 2012. I change the oil every 3k miles. It is the easiest oil change to do yourself.
Only issue on the first 3.6 was thermostat went bad after 8 years.

Sounds painful honestly but hey whatever works!!

I think the engines are good and work horse, nothing special to be done. Change oil, drive them reasonably and be happy. They like most modern engines will last a long time.

You made me go back and correct it lol

I recommend 2 scoops of DD Fudgey Nut Blast applied directly to the oil filter ?

Follow mfg. recommended maintenance intervals ( I do 5K on oil changes), use top tier fuel & oil, drive it reasonably, and you should be good for many many miles.
Well north of 10M of these engines produced over the years with a great track record. ?

I went with the 3.6 because of it's maturity and reliability. I change the oil more frequently than FCA recommends, alternating between DYI and having the dealer do it. I've changed the fluid in both differentials (when I upgraded to ARB covers), and I plan to do my Transmission fluid change (once I get confirmation of how much fluid I need to buy), and eventually my transfer case fluid.

My buddies motivated me, and they were right, it's easy.

Now if I can only get them to learn how to shell script. It's easy. It really is.

On my 2009 Ram I put on 320,000 miles and the engine runs perfect. I used the appropiate synthetic oil with Mopar filters every 5,000 miles. I also added an engine cooler at the filter. For the transmission I added the larger trans cooler and got 250,000 miles before failure. Usually they last about 125 to 150 before it goes, but by adding the larger cooler I feel like it gave me an additional 100 thosand miles. Heat would be my concern for enine reliability, although running it too cool is not good either.
