Hi guys,

I did the first oil change by myself today, after that I drove my truck out about 20 miles and everything seems fine. Then I went out for a late night movie, when I came back and parked in my garage I suddenly smell burning oil and found there is a huge oil leaking. I think the oil was leaking from the oil filter since I used a oil vacuum pump to get the old oil out and never touched the drain plug. I do removed the old O ring from the oil filter cap. The only thing I thought I could do wrong is that I kinds of over tighten the oil filter when I put them back using a wrench. Then I realized that so I loosed it and re tighten it by hand.
So is that what I thought cause the leaking? What should I do now? Buy a whole new oil filter? Do I need to clean the oil around engine even at somewhere I cannot see and how should I do that? And one last stupid question, how should I know if the oil filter Is tight enough without a torque wrench?

A quick update, I check the oil filter cap today, not sure if I placed the O ring to a wrong position. Which one is correct? It's a 2014 JGC and I use the new type of oil filter from MOPAR.

Re: Help needed about oil leaking after oil change

Not sure what year your WK2 is, but the 2014's use a different P/N filter on the 3.6 from the older 11-13... this might be the cause of your leak?

Be aware, oil filter design for 2014+ V6 has changed!

Thanks for the replying, I should update the model information, it's a 2014 JGC and I do use the new type of oil filter.

Re: Help needed about oil leaking after oil change

Also the V6 filter needs to be tightened with a socket / ratchet NOT by hand. I don't have a torque wrench, I just use slight pressure and don't over do it. The problem might be that you tightened it by hand.

Yeah, that makes sense. So can I use the oil filter and O ring again by just tighten it with a ratchet? Do I need to buy a whole new one?

I did my first oil change today and my o-ring was like this pic, in the recess/groove closer towards the threaded portion of the cap. Torque is 18lbft which if you don't own torque wrench, is a fair amount... definitely more than hand-tight; you should be ok to snug with a standard 3/8 drive ratchet (just don't get carried away and go all gorilla-tight on her).

You've prob already resolved this issue but just in case, you shouldn't need to buy a new filter/o-ring... re-position your o-ring (if required) and tighten the cap back up. The flange on the cap should be flush to the filter housing.

Hope you get things sorted out ok.

Re: Help needed about oil leaking after oil change

Since you leaked oil I would check the level. Better be safe than sorry.

Thanks J. Just did exactly what you said. Seems there's still some oil tapping when I stop the truck. Don't know if they are the residual oil from the previous leaking. The oil level is unchanged and no oil trace when I wipe the around of oil filter after every stop. Any experience on how to clean the residual oil or how long will it disappear? Also, a funny thing about the torque wrench I used, I've never heard that click sound even in a really close distance. Don't know if the 18 lbft is too low for it, it's a 1/2 drive torque wrench with 10-150 lbft range.

I gave the old one a try but also ordered a new one. Hope the small amount oil drop when I stop my car is caused by the residual oil from last leaking...

Re: Help needed about oil leaking after oil change

If your wrench is the clicker type, you will know when it does. Set it to the 10 pound setting first. That way you will know how it feels/sounds.

As a general rule, torque wrenches are not as accurate at the far ends of their range... I'd use a 3/8 drive if you want to torque the cap.
