Noise you are hearing is likely a lifter...you can safely add a pint of marvel oil to either new or used oil and usually it will clear it up.
I also recommend the use of a synthetic oil to prevent problems such as yours. It is more chemically stable and does not form sludge as readily as do conventional lubricants.
Don't expect instant results...It took time to create sludge in lifter...it takes time to dissolve it.

it could be a bad fuel pressure regulator. or a blocked fuel filter. heres the regulator symtoms. the vehicle runs rough, the engine will not start ( usually in the morning )many times engine starts but stalls shortly after starting. a bad regulator can result in fowled spark plugs, replacement is only cure. ( black soot on plugs, blake smoke from tail pipe, running rough and stalling. check fuel filter first.

I have a 1997 2.5 jeep wrangler.when you first start the engine it runs and sounds fine, then after about 20 seconds it begins to have a knocking sound only at idle. when you press the gas you cant hear...


It may be piston slap. This is caused by either engine wear with the piston bores being too large for the pistons, or by poor manufacturing tolerances, or a combination of both.

To test for this, start the engine up first thing in the morning and run it for about thirty seconds while you listen carefully and memorise the sound and intensity. Turn the engine off quickly, remove the spark plugs and put two squirts of motor oil into each cylinder. Reinstall the plugs, start the engine up again and listen. If you have piston slap the noise will have been greatly reduced or even eliminated for about thirty seconds seconds and then returns.

The fix is to rebuild or replace the engine, but if it works just fine then don't worry. Many slappy engines keep going for tens of thousands more mile. The fact that your knocking is only at idle suggests your crankshaft is not to blame.

Tapping noise in the engine


That noise is most likely cam follower noise ( formally know as lifters), this is common but no normal, it should disappear after a few seconds when the engine is started, talk to the dealer about the noise, he may be able to help even if you are out of warranty.
