Question about Cars & Trucks
Hello Ernie Santacruz,
First best guess is that you are running the
WRONG OCTANE gasoline...
Some folks try to save a few pennies by running a
lower grade than is required...
Your question history is only this question...
No make or model... year...
Can you clarify WHAT your octance recommendation is...
What octane you have actually been using.
A couple of help diagnostic tips there might
help minimize your ENGINE DAMAGE
(I'm just saying)
Couple of clues would seriously help!

SOURCE: Unusual ping noise
I have heard the same thing in my '07 Altima 2.5 S. I asked a mechanic @ the local dealer, and he said he doesn't know what it is and couldn't get the car to make the noise when he drove it.

SOURCE: 04 Endeavor rattling noise
I had the same problem! I crawled underneath the car and discovered that a heat shield on the exhaust header pipe was corroded and rattling against the exhaust pipe. (Before the muffler)
I removed the portion and clamps and solved the problem. Give it a try.

SOURCE: Ticking noise
If it's just a light ticking alot of the 2.2 litres have the same problem if it's what is wrong with mine it's the lifters knocking and the same with alot of other gm motors trying using an oil stabilizer like lucas

SOURCE: Knocking noise from under hood
ok the lifters are making noise, make sure you are using the right oil for your temp zone. also add some lucas oil to your engine oil, it will quiet down the engine.

THE ticking noise coming from the engine ..is it just a 1 tick on idle at about each rev of engine,,and does it make any differance to the running of engine ,,Does it get softer when it gets warmer.
As it sounds like a loose tappet and being a oil adjusted tappets this thought of thing does come in now and again. and the best thing to do is to get a small plastic tube 25mm (or 1' ) and 2ft long and put it to your ear and listen at the top of the rocker cover ans see if the noise gets louder in a certen place ,as you will hear it if it is there..
Other wise it could be a Small end on the conrod which the piston is connected to.... lets hope not.
So let me know as soon as poss the answers to all the above. Ron
