Lifters sticking on 3.8
 

My rear main oil seal started leaking at 50,000 miles. I had that fixed (which wasnt cheap), and now the lifters sound like they are making a loud ticking sound on startup. They do this for a couple of seconds and then they are quiet. they only started doing this after the rear main seal was fixed. maybe its just coincidence but it seems kind of odd. The jeep is a 2011 and currently has 52,000 miles. The oil level is right where it should be. I have been checking it regularly since the repair. Is this something I should be concerned about?

Could simply be the oil filter. Some brands have crappy anti drain back valves. I tried different brands and went back to the Mopar brand.

Yup just stick with the factory filter. No problems its even cheaper than most out there

So you think simply changing my oil filter should fix the problem? Ill give it a shot

What oil are you running?

I have been using full synthetic i believe 5W-20 since i bought it 2 years ago. The shop that did the repair did an oil change with a brand that i have never heard of.

I would switch to 5W30 and also go with a different oil filter. You didn't mention the brand of filter you are currently using. My last JK was an 07, and never had any lifter noise or dry starting. I always ran 5W30 Castrol with a Mopar filter and changed the oil every 3k miles.

Other than using only Mopar OEM oil filters, I would also recommend using Valvoline High Mileage Synth-blend 5w-30 (red bottle). Engine has been loving this and have used it for the past 3 oil changes....I'm at 40K miles now.

Just curious as to why you think you need a high mileage blend at barely 40k mileage mark. I Use synthetic every 10k and change the filter every 3k.

I'd like to know too, usually those oils are formulated for engines with alot of deposits and that run extra hot right?
