ticking noise???
 
so about a week ago i started hearing a ticking noise from my engine, its not constant, its goes about five seconds then stops about five seconds and so on...i dont think its anything major but im not sure what the deal is...2002 tj inline 6 4.0 auto tranny, 60, 000 miles...

Probably a sticky valve. Should go away, keep an eye on it in case it gets worse.

engine oil flush works well. just get a bottle of flush from parts store, it is mostly keroscene. follow the directions, but usually poor it in, let it run for 5 mins. and change oil. if you can, let oil and filter drain for a long time. you can use a 10/40 oil if you want. maybe go with a max life oil for 75k or higher engines. valvoline makes one

almost all 4.0's make a little noise after a while, and they'll go for a million miles. i'd say flush it, and change the oil every 3k, you'll be fine.

Try to determine were it is coming from first.It could be an exhaust manifold leak.Sometimes they sound like a tick in the engine.I would do that before using an engine flush as mentioned it is mostly Kerosene and I don't really recommend any kind of solvents being run in an engine for no length of time.Or that is my opinion anyway!

the engine flush for 5 mins. will cause no damage. the little bit of solvent, mixed w/ 6 qts of oil is of no harm. long duration, or too frequently maybe. it is way better than damaging sludge cloggin oil passages, and parts not bein lubricated at all.

checking exhaust manifold is a good idea.

Don't get me wrong jpdocdave I mean it is on the market for the purpose of flushing the sludge out of an engine and it does work but I was just saying I would not use it in an engine unless I was sure it had an oil return problem or a deferent valve sticking or a lifter pecking due to sludge or clogging.In other words I would not use it as regular maintenance.I have used it on those extreme cases and a few it worked but one in particular it did finish it off but I think it was deeper than a lifter peck from the start(Cavalier2.0) luckily it was mine and not a customers:eek:

Mine was ticking a couple of weeks ago and it ended up being the exhaust connection between the manifold and the pipe. The fasteners loosened up. The manual shows that there is no gasket, so I just retightened and the noise went away! We'll see how long until it loosens again!

no prob, i think i sounded defensive and i wasn't. i would only use it if there was a reason. i have disassembled a motor that was sludged up cuz the customer didn't change the oil for 12k, turned out a valve spring was broken. but we flushed the oil first. when i took it apart, the engine was clean. worked well, i also had it fix a nasty noise i thought for sure the engine was gone.

actaully i made fun of my boss for making me do it, then it worked. it is a good product, especially cuz people don't change their oil like they should.
