Richard, It could be something as simple as a bad belt tensioner to something as major as worn bad rod or crank bearings.
Best to find a knowledgeable buddy or a mechanic you can trust and have them diagnose.
Hope this helps you out. Good luck.

    Richard, if your dad feels the noise sounds lower on engine, it could be the pistons connecting rod bearings bad. If you would like to try and locate noise, take a short old broom handle, wooden dowel or even a piece of old garden hose and use it like a doctors stethoscope, wood/hose to your ear and touch other end to engine areas, probing around engine while running to locate where noise is at its loudest. **Be carefull around rotating parts**

98 ford escort ticking never loses power nor sluggish.pulled each each sparkplug ticking never stopped.what could it be

You mention a "ticking" sound,,is this from the top or bottom of engine..?

Does the ticking go on acceleration or increase with engine speed..?

A ticking noise from the top usually indicates camshaft/valve noise..

Run your engine until at normal temperature, then turn off and leave for 5 minutes for oil to settle..

Make sure your car is on level ground and check your oil level..wipe dipstick and check it again, make sure you push the dipstick all the way in an re check oil level. Top up if necessary.

The best thing to do is remove old oil filter. Drop the old oil and fit a new filter, top up with new oil, run the car and check oil level again, top up if necessary.

Low oil and old oil can wear thin and cause ticking noise from top of engine, and will also NOT PROTECT your engine...oil is the blood of your car, check levels weekly at most and change every 12 months or as recommended by your car booklet.. Use the BEST oil you can afford.

Why is my engine clicking

First ask around about a reputable mechanic. they are out there. Got to one and ask if he could tell you what the noise is. I would not wait too long as you could do damage and cost a lot f money to repair Yes it will cost you but that is a part of owning a car. It might not be an expensive fix but don't take a chance.

My 92 eldorado has a ticking sound when car drives the noise came out no where from the passager side is it my oil pump it gets lounder when gas is apply

What is the oil pressure when ticking starts? How many miles on engine? How often do you change oil? What oil do you use? What brand filters do you use? Is this a Northstar engine?

High mileage Northstars (and others) will have tappet noise as they wear. You might try adding a quart of Marvel Mystery oil at next oil change, but if low oil pressure is the problem, try changing to a slightly thicker oil, say 20-50. If you don't know what the oil presure is, install a mechanical guage. I had a freind with a low pressure problem on very high mileage car who began using straight 50W oil and car ran another 3 years/60K miles before dying.

Best would be to check the oil pump filter in the sump of the engine. these also clog up and drops the oil pressure resulting in a warning light

I have a 2003 Chevy Impala. I ran my car with no oil and now I'm hearing a loud ticking/knocking noise coming from under my valve cover. I added 2 bottles of oil after finding out that I didnt have any...

might be the valves have been damaged running without oil
- or the crankshaft / camshaft / main bearings
most probably you have to let the engine be rebuilt by a mechanic
(expect cost of more than US$ 2.000)
or get another (used) engine at a scrapyard 2003-chevy-wutfveiel3ypko01ydor435x-5-0.jpg 2003-chevy-wutfveiel3ypko01ydor435x-5-2.jpg

3.1L engine ticking noise

If you noticed any wear grooves on the rocker pivots, it could be that the rockers are worn. changer any that show obvious wear. Some movement of a rocker when not under tension is normal but should not be excessive. You can also check to see if any rockers have less travel than others by slowly turning engine by hand and measuring the travel on each (intakes may vary from exhaust, but should not vary from other similar ones) If any move far less than others it can be due to a collapsed or worn lifter, or worn cam lobe. Piston slap is a different issue and usually can be identified only by a good tech with lots of experience.
