Dead Pentastar

[PNW Jeeper]

Javed, is that a checklist on the airbox ?

Can't put 0W-30 there

 

[OVERKILL]

I clean my engine bay like every week and things feel pretty nice and well built. I use interior detailing spray to keep things nice and shiny.

Watch my lil Pentastar Jeep in action, on 37's. When I was stock and stable, I was zipping around taunting BMW and Audi crossovers. I'm still a rocket ship but in a straight line

With all these early changes you do - are you keeping the oil filter in place ?

Pentastar is confusing.

Some had a SADI camshaft lobe failure, and some did not.
Some had needle rocker arm failures, and some did not.
Some seem to have a burnt exhaust valve thing on one side - but some do not
Now it seems that transverse applications have a head gasket issue on the back bank? But longitudinal do not? Not sure on this one - its the first I am hearing.
They all have an oil cooler issue. And unfortunately even swapping one out seems to be not 100% guarantee of fix.

It definitely seems to be a Monday / Friday thing.

Of course everyone tells me the AMC designed Jeep 4.7 was junk. I had one and my BIL had the HO one, and neither of us had any engine problems at pretty high mileage.

It’s a troll account. Don’t entertain it, or it will continue. He’s making everything up to gain some kind of attention on a small internet board. It’s pathetic.

I’m not sure why the mods allow this. I created a thread a while back asking about long-time contributing members of the forum who haven’t been around lately, and they basically threatened to make me dig the hole that they’d bury my account in.

But, for some reason they’re ok with us having our time wasted answering duplicate accounts by pathetic trolls.

I'll have to remember that next time I change the oil in my 2016 JK Rubicon and fill the sump with ESP 0W30.

Sorry that your feelings were hurt, but I sincerely doubt that it was said exactly that way.

We don’t comment on individual cases. If a person did something to get banned - out of respect for that person, that case remains confidential. You would be surprised what people say to others, including staff, when hiding behind a keyboard.

We don’t allow trolls, period.

Folks who can’t follow our rules don’t last long, either.

But there are lots of folks who have a personality type that others might find annoying.

As long as our standards for behavior are followed, folks can stay.

This is fantastic, and I’m tempted to do this, maybe with a label maker. You have me thinking about the organization. I would probably go oil, drain plug, size, torque, filter, type, size, torque.

I like the YT OP, he's funny and speaks with some solid background in the used engine realm. I know there will be haters here that will not accept that 3.6L Stellantis/Chrysler rear bank head gaskets are a problem in east-west installations, but whatever, I guess time will tell.

Unfortunately - trolling is part of the internet …
Stir up arguments … derailing threads etc …

You’re sorry? I’m not sure you’re being honest. Where were you when I had to cry myself to sleep?

This dude PNW Jeeper/Javed/JeepJ/et al, has been obviously trolling and spinning up new accounts for weeks now. I tried to help one of the earlier iterations only to find out later it was a troll account. This dude gets to stay on here and troll well-meaning members of the forum, and I get sarcastic remarks from site staff.

 

[svtrit]

You happen to know why vs a longitudinal install?

Heat. There isn't enough airflow back there compared to a Jeep, Charger, Challenger or Ram installation. The old Dodge Caravan up to 2020 did not have an issue, so it must be much tighter on a Pacifica.

Or some won’t own a transverse motor type of vehicle …

This doesn't make any sense to me. Its water cooled. If you told me some other component overheated - like coils or whatever, It would make sense. I can't see airflow around the engine have a meaningful temperature difference on a head gasket.

Am I way off base here? If I am then I learned something today.

Don’t forget “motor oil rookie” and “jeep junkie”.

He’s also on the JL Forum bashing Amsoil and HPL……

I need to check that out -
Sure hope it’s better than the Wrangler whattheheck site …

Front wheel drive is by the most efficient choice for the majority of drivers that know nothing about cars, or driving for that matter. Wet, icy, whatever - Front wheel drive is better for the masses.

There also much cheaper to assemble.

I prefer real 4wd also, but were special use cases. The fact that other OEM's can make transverse mounted engines without issue is a blight on the 3.6, not the overall tech.

I will admit I would hate to work on them. I had a 3.1 on a Cutlass supreme and you could remove a upper motor mount with 1 bolt and rotate the entire engine ahead a few inches - by design, so it wasn't bad at all. Back when cars were designed to be serviced.

No, I change the filter too
