Changed the oil in the truck today, 4.7 liter. Took large tongue & groove pliers to get it off.
Check the oil regularly, haven't had to add any since last change. Now turn it a 1/4 turn and you can't turn it by hand.
Anybody else have this problem?

Thanks

 

My brother once snapped the plastic filler neck off his near-new Ram 4.7L while trying to take the cap off by hand.

Have to be careful with it.

 

I think the plastic on the filler warps after a thousand heat cycles. I have a similar issue with mine, been meaning to replace it.

 

some times mine needs large channel locks to get it off sometimes it just turns in my hand. no rhyme or reason!

 

Never had a problem. But, I've always changed the oil after driving it for about 20 minutes. Maybe that helps?

Could swap it out with a billet filler cap? I haven't looked, but I'm sure something is out there.
