V6 Gas Engines?

[El Huapo]

Not sure where to post this question but I see various special topics on Eco-diesels, Heavy-duty, etc. but I haven't found any ?Forum? if that's the right term? made especially for the gasoline V6 engines. Is it in there somewhere and I haven't found it? Please enlighten me if so.
Would such a forum be of interest to anyone else? I started looking for one after reading so many posts about valve/lifter troubles on the hemi engines and began to search to see if my truck had a similar setup to watch out for. It seems not to be a similar valve train to the hemi's in my 3.6 V6, I think I like that.

Anyway, what do the rest of you think of a specialized V6 question and answer area in here?

If you're looking for forums on the engine solely I would recommend searching for the Grand Cherokee/Durango forums as those vehicles have the Pentastar as well. I'm not aware of any Ram Pentastar forums but I'm sure they do exist

heh... yeah not even close to similar. A Hemi with a valvetrain like yours would be a (very heavy) screamer

So you think the V6 valvetrain would make the hemi a hotter engine? Because less moving weight, = higher rev capability (I'm totally guessing here)?

Absolutely. Unlikely it would improve regular ol' drivability because the gains would be mostly at the top end but shorter valve stems and more, lighter valves mean more ambitious cam grinds are available, pretty much guaranteed greater air flow through the heads, higher workable RPM available - notice how the 3.6 makes its peak horsepower like 1000 rpm above where the Hemi's already been tucked in and gone to bed. If the Hemi could keep making the same torque at 6300rpm it makes at 4000 (somewhat like the 3.6 does..) it would work out to a 450+ horsepower engine on that alone.

You can actually see a kinda similar example to this, the modular 4.6 pushrod V8 in a ~2004 Mustang GT was doing 260 horsepower somewhere around 4500 rpm or so, 302 lb-ft of torque... while the DOHC version of that engine in the same year Mustang Mach 1 was doing 305 horsepower at 5800 rpm and 320 lbs-ft torque on basically the same bottom end geometry. That stuff was all way lower tech than the modern Ram 3.6 which makes roughly the same horsepower on a liter less displacement and two less pistons.

Yeah I think a DOHC "Hemi" would pretty easily crush 450 horsepower. Not saying it would be a better engine exactly because it would be dimensionally huge, heavy, and it probably wouldn't have a ton of benefit down in the 1000-3000 rpm range where we really spend most of our time actually driving. Might even get marginally worse fuel mileage under everyday driving conditions because even while idling or cruising around at a lazy 1500 rpm on the highway it's still more work to rotate four camshafts against 32 valves than it is to rotate one camshaft against 16 of them, pushrods or not.

4 valves = better breathing. Aluminum block = lighter weight, integrated exhaust manifolds = no hemi tick.

Thats 3 things right there.

To the OP's original question. Feel free to ask anything in the engine forum here. You will get the benefit of those that have driven both the v6 and the v8. Someone will see it.

I think it's because the Pentastar is such a great engine that there's nothing to discuss. On the other hand, there's endless threads on Hemi-tick, relocating the Hemi oil filter so you can access it, Hemi lifter, valve and cam issues, how to replace the 16 spark plugs, what oil and additives to use to make a Hemi stop sounding like a sewing machine, on and on.

So just rest easy... your V6 Pentastar has NOTHING in common with the Hemi. It was designed from the ground up to be a far superior engine

A sewing machine? That made me laugh so hard[emoji23][emoji23][emoji23] its true though I'll give you that

I have the gas V6 in my 2016 Ram, haven’t had any issues with it so far.

 

[That_CAT_Guy]

I'm very surprised by the V6 tbh. I bought it cause the truck itself driven off the lot was $24k, and I wasn't going to pass up a almost new barely even used truck at that price.

Since I've had it though, the thought of having a Hemi faded away. I don't really pull anything other then a boat and maybe a car dolly every now and then but so far I've had no issues with my V6...drivetrain wise...

My fill neck on my fuel tank though is another separate ongoing issue

There's a bunch of Pentastar forums out there, Ram or otherwise, with specific categories for this engine.

Great engine for these trucks, but a lot of that is due to the awesome 8spd they're coupled to.

As much as I'd love a V8 simply because I've never owned one in 35yrs of driving, I'd buy another Pentastar powered Ram 1500 in a heartbeat.

When you buy a ram you know you're going to have to compromise. If you buy the v6 you'll get great reliability but a truck that can barely get out of it's own way. If you get the 5.7 hemi you'll have a great fast truck but one that will undoubtedly experience high mileage issues, minor or major

My local dealer finally changed-out my 2018 filler tube to the new one under warranty a few weeks ago, and it fills fine now. No cutoffs, and not getting stuck like it was. If you're still under 36K miles go in and demand they replace yours. And don't let them play dumb, they KNOW it's an issue on 2015 and 2019 Rams.

The service manager already told me it was a known issue and to bring it in wednesday, they'd look at it and probably rig something up to get me rolling while they wait on the new one to come in

Having driven both Hemi and pentastar powered Ram 1500s, I don't agree with that at all, but I came from a time when a small block chevy V8 powered truck had like 170hp at best and not even as much torque as a pentastar V6. Young bucks have no idea.

Yea i remember when V8 trucks couldnt even get out of their own way too, and drank more gas then the fuel pumps could keep pumping

Good deal. You're gonna LOVE when they get the new one in. I struggled with mine for 2 years, getting stuck, cutting off, dreading each fill-up. Now it's normal.

BTW to those claiming the Pentastar V6 is slow, I don't think you've driven one. I normally drive mine pretty easy, but when I need to punch it, it pins me in the seat!

I agree. I too was surprised by the V-6 in my 2018 Tradesman. Have had 5 Ram Hemi since 2003. When I decided to replace my 2003 1500 5.7 with 265K miles. I did not want to pay more than about $20k. While shopping for a used 2016-2018 1500 5.7 I tripped across a dealer who had 4 NEW 2018 3.6 Tradesman QC with the upgrade chrome package. He claims he lost track of them in his inventory and had been paying flooring on them. He had to get them sold. At $22k I bought one over the net site unseen. Picked it up a few days later. That truck has grown on me. I love our 2018 2500 6.4. A real man's truck. But,,,,this V-6 gets up and goes. I put a CAI and removed the resonator muffler to get it over its stuffy nose. With the 8 speed set in 5 or six around town and 8 on the Hwy,,,the mileage is a welcome change. And the performance is surprising. We will never tow with this truck.
Had the problem with the out of spec gas filler neck. Dealer tried to play dumb and FCA is only replacing the ones that the customer complains and the dealer confirms. Once you get under the truck and look closely at the filler neck, you can see the problem. Some of the filler necks came in from the vendor with the neck attached to the splash guard a bit to high. This causes the new CARB socialist compliant filler guns to catch on the top of the gun and they are ***** to get out. Tilting the neck angle "forward" toward the door stops the gun from getting caught. I simply took a long stainless hose clamp. Put a rubber sleeve on it and attached it to a sheet metal hole above the neck. Pushing the filler hose "up" under the truck is just enough to correct. The replacement part that is on back order, does the same thing. It changes the angle of the neck. Their are a couple good threads on the forum that show how others corrected. Other than that, I ordered a leather steering wheel cover that I will install today. After years of leather steering wheels, the plastic rubber tradesman wheel had to be addressed.

I've never really had an issue with mine, up until I started having issues Now, here's a good question, can I request they see if my computer has any updates for it....if that's a thing....and have them flash the new update while it's there?

After owning many Hemis and Mopar V-8's over the years, I finally got a 3.6L in my '17 Ram Sport. I can honestly say that I'm not missing much if any power, although I do not pull anything heavy with it. It's my daily driver and I love it. The savings in gas alone will make me purchase another one in the future. It does have some balls when I romp on it too. Love it!!!
