Question about 2002 Oldsmobile Alero

1 Answer

Alright, so my sister came over and when she was leaving she started her 2002 olds alero and i heard a ticking sound. It sounded like more than one lifter was ticking. Is this a sign that the oil pump is going out? I had her turn the car off after like four seconds. Checked the oil, it was full engine sludge shouldn't be a problem. She started it up a minute later and it didn't tick... What the HELL?

That tricking noise is common on the 3.4 gm engine's. It's called piston slap, you get it most of the time on first start or when you turn the car off and it just cooled enough for the pistons contract again.
There is nothing we can do about it, with the newer engines being built with higher tolerance you get annoying  noise. 
Best thing to do is to do oil and filter changes every 3000 miles, and warming up the car about 3 min before driving off. 
The way you engine was made, you don't have to wait since there is tolerance for expansion but your going to wear out the cylinder quicker. 
I find that adding Lucas Oil treatment with every oil change has eliminated the piston slap from my wife's Montana. Good luck and hope this helps.

    Oil sludge is a big problem, sludge blocks up the oil journal and starves the vital engine componets of oil like the Crackshaft Bearing and lifter's. If there is not enough oil flow you could burn out a bearing and that would cast a new motor. 

    Try adding Marvil Mystery Oil which i believe Auto Zone sells to your engine oil about 300 miles or say a week before you get the oil changed. That your help clean out the oil journals before your go for an oil change. Try doing that for the next 4 oil changes and then ever second one after that. 

    That would keep the internal parts in the engine clean and free of carbon and sludge. Don't forget to *** Lucas engine oil treatment every time you change the oil. 

    Good luck and hope this helps.

Why when I turn my steering wheel either way my drivers front strut spring catches and spins on a 2002 olds alero v6

I am guessing you dont have standard wheels fitted. Suspect incorrect size. If standard sounds like you have front end damage altering the steering geometry.

Why does not start?

I have never heard of an engine noise being described as a tick tack rattling noise. (I assume you mean Tick Tack candy/breathmints?) \

Either way, if it doesnt start, but just makes a rattling/knocking sound, I would ask you did it just quit on you and not restart? Or did it get you where you were going and then would not start when you were ready to leave? If the answer to the first question is yes, then you are likely facing a broken timing belt. The sound you hear are the valves coming into contact with the pistons when you are cranking the starter. This is a bad sound. Lets hope your answer was no to the first and yes to the second. Are you sure have gas? I cannot tell you how many times people have told me "It just won't start!" only to pour a gallon of gas in and varrroooom! What about oil? The tick tack sound just doesn't sound like a healthy engine sound in my head. Do you have oil in the engine? Does somebody hate you enough to drop nuts and bolts into your intake manifold? That would sound like tick tacks. BIG GIANT tick tacks, but tick tacks nonetheless.

try leaving the key on for 10-15 minutes, or however long it takes for the security light to go off. If this works it sounds like you will need to have the exciter ring on the ignition lock cylinder changed.

Car keep cuting off when i start it in the moning

Sounds like your anti theft system. You can manually reset it. Turn the key on, and leave it for 10-15 minutes. Try to start after this. If this doesn't work, may be time for a trip to the GM dealer.

Fast Blinker noise driving me crazy Mystery of what the heck it could be

Replace the Turn Signal Relay, it's getting old and wore out. When you replace it, the sound will remain, but it won't be near as fast a sound.
