Multiple problems. Ticking ( probably lifter ) and screeching noise with low battery.

Hi, I'm not exactly the best car person on the planet so i apologize in advance, but i had a friend who loves Grand Prix's and got all of her information to fix her car from forums...so i figure i'd give it a try.

O.k. I have 2 possibly more problems.

one of them is a constant ticking noise that is synched with the accelleration. I've looked around that that pretty much looks like a dead lifter, I'm not exactly sure what that means. lol. but at least i know what to tell the mechanic.

Also...how long is it safe to drive on this before major damage is done to the engine? Besides the next problem i'm about to say...nothing has really ended up wrong, but i'd rather not let it go on and on and then BOOM. I'm suddenly out of a car.

Now the 2nd problem i have is, this insanely loud screeching noise that happens when the battery is low...which for some reason, has been very low ( near the redlines of the gauge ) everytime that I start the car...after about 2 or 3 minutes of letting it idol the battery gauge goes up, and when the gauge gets about half full the screeching goes away. Also if i turn on the AC the battery drops down like it's going to die and the screeching comes back for a bit until I turn off the AC and let the car get back to normal battery level. I'm not sure if the two are related, but with more and more problems happening, i'm trying to catch and stop these before it gets worse.

The car is a 95 Camaro with a 3800, everything in it is stock, it's a standard and has 121563 miles on it. If there is anymore information needed, i'll answer them to the best of my knowledge.

Thanks in advance.

Your screeching is the belt. Best guess would be bad bearings in the tensioner or something like that.

The ticking could be a lot of things.

I don't suppose that's something I can get in there and fix without having to take it to a mechanic is it?

Ticking could be a varieity of problems.. My wifes ford escort had a ticking which I failed to look into on time. it had 180K on it. It turned out that it was a roller lifter that had rotated in the bore because the alighment tab had broken.. after a few thousand miles of rotating on the wrong axis the cam wore the lifter wheel out and it grenaded itself into the engine..

The belt tensioner has been addressed already.As far as the suspect lifter goes,you could try removing the rocker arm and spraying carb clean down the pushrod.let it work overnight then reassemble and drop the oil and filter and refire.Isolating the lifter shoud be simple at TDC.The rocker will not have have preload.

Re: Multiple problems. Ticking ( probably lifter ) and screeching noise with low battery.

The loud belt screeching at startup is probably caused by the heavy load from the alternator, which is working hard to try and charge the battery back up from the heavy current load you just created by using the starter. After a minute or two, the load on the alternator decreases and the screeching diminishes somewhat. Still, as stated, you've got a bad belt or tensioner.........

For the ticking noise, I would maybe try some engine flush. This usually goes into oil, then you run engine for a bit (like 15 minutes or so), then drain oil, changing filter as well. This would be the cheapest and easiest thing to try, and I know it works. It fixed a sticking lifter I had in a '88 Lincoln LSC Mark VII and I got another 40,000 miles out of that baby.

Thanks for the advice. She died this morning and wouldn't start up. T_T

It's really my dad's car, and despite me telling him to take it into the shop and get it looked at 3 years ago, he's decided to wait until....well now...to get it fixed. I'm going out today to try the engine flush. So hopefully that'll fix the lifter problem without having to pay a crap load to have someone tear apart the engine to get to it.

Wish me luck. I'm gonna need it, especially if this car becomes mine in like 2 or 3 weeks. xD

Follow the directions carefully on the flush...................

The belt issue could also be caused by a frozen pulley on the A/C unit, or something like that. Should be easy to spot that problem. Not sure how easy (err, cheap) it will be to fix, but at least you should be able to quickly get to the cause.......

Keep us posted.

Sounds like a weak batery is requiring more alternator load and slipping the belt. The ticking could also be a small exhaust leak.

Re: Multiple problems. Ticking ( probably lifter ) and screeching noise with low battery.

Update :

Just had the battery tested and it's popping out like 12.40 volts i think...
We're taking the alternator off now and sending it up to have it tested. I'll look for the engine flush to cure the lifter problem.

Thanks for all the advice.

Update 2.0 :

O.k. Alternator is working fine, battery is good, ( allthough i may be getting a new one soon because the one we have is....well lets just say that it's ugly...lol. )
The manager of Autozone brought out a tensioner rod to try and get a new belt on, and we found out that the tensioner isn't doing what it's supposed to. When we tried to loosen the bolt it would go maybe an inch and then it would start moving the belt...so...is that a possibility of what's making the ticking noise also?

We're taking the tensioner to be fixed tomorrow. I'll post more after that. xD
thanks again.
