Engine clicking every morning after startup...

I heard this is common with Jeeps. It usually goes away after driving for a couple of minutes. I'm planning on changing my oil soon as was just wondering if there is anything I can add during the process to help reduce this at all? I think I recall someone mentioning replacing a quart of oil with atf? I use mobil one synthetic. Thxs.

1. No. Don't do that.
2. Try a conventional oil.

If it's worth doing, then it's worth overdoing.

Switching back, huh? I've been using synthetic for so long... any recommendations on a conventional oil and filter?

Valvoline 10w-30 conventional is a very good oil. I use that with a wix/napa gold/car quest filter and have good results. If you're stuck on the mobil brand, clean 5000 is a good oil too.

There's about a thousand threads/opinions on that.

Any of the name brands are good. Unless you're in very specific circumstances where synthetic really will perform better/longer for you, then there's no reason to use it. 10w-30 dino oil will get you there. The filters mentioned above are great choices.

If it's worth doing, then it's worth overdoing.

And for all to know Kragen now carries Wix filters, since they merged with O'Reilys and Schucks and all them. I was happy to see that yesterday as before only Napa carried them here where I live and it's a 40 mile round trip there.

An ugly Jeep with some stuff.

Is your oil level Ok. Clicking for a while after start up can be a symptom of low oil level.

Yeah, it does it even after an oil change. I don't have any leaks either.

Mine was a cracked weld on a cat (right near the exhaust header). My neighbour welded a little bead on, and the noise went away. In the mean time I tested it with a pipe clamp.

keep us updated if you figure it out. I have the exact same noise. I'm pretty sure its the exhaust manifold.

Yeah, I just heard it was common with the engines. Hearing that you guys found some defects that might correct the problem has me thinking now. I'll check it out and post up if I can find anything.

Clicking after start-up is usually a lifter not pumping up, a push rod or a rocker. In most cases it's a lifter who's not pumping. Once the oil warms and is a tad more fluid, it pumps up and the noise goes away.

I would pull the valve cover and find which one it is. Some time the rockers are just a tad loose.

I would change the oil, oil is not going to cause this problem, it mechanical.

Hey Dryseals- you recommend changing back to conventional from synthetic? I know it's not going to solve the problem but it will at least save me some cash on oil changes. Yeah, I'll have to find a bud or take it in somewhere to have them look at it. I'm not too good with the self maintenance. The problem only seems to arise on cold mornings. I've never noticed the clicking during warm weather periods.

I typed too fast, no I would not recommend going back to the dino oil, I'm a firm believer in synthetics, the protection they provide is far superior to dino oil. I work in an industry/plant who has well over 400 pumps and motors and most are over the 100 HP range. We use synthetics because they do offer better protection.

There's a lot of things that can cause an early morning tick. A valve sticking can cause the same noise. A stethoscope might help you determine where the noise is coming from, sometimes a long handled screw driver will work too.
