1998 Chevrolet Malibu problems...

Last Saturday I traded in a 1999 Ford Escort for a 98 Malibu. The car sounded fine, drove good, was really comfortable. The only problem I seen was that the coolant light would come on but the coolant was full. So I figured it having dexcool it was turning to jelly and the sensor was getting stuck. The oil was a little over full but sometimes that is a common mistake. I done it a few times to my cavalier I had. The car has 123,000 miles on it and it seemed to be a good deal. Monday morning I noticed a slight ticking noise coming from the engine. One of my co-workers told me it sounded like I had a bad lifter. Since monday the ticking has began to last longer and get louder and louder. I came home tonight and decided to research a little bit and found out about coolant leaking into the intake manifold. My wife's step dad told me that this ticking isn't gonna hurt anything. I don't know to much about cars so I don't really know. I don't have any clue how much it would cost to have it fixed and I can't afford to pay a whole lot. I live in Georgia and they have no laws regarding the sales of used cars.

The only thing on or in the motor that should be ticking is the fuel injectors.

How does ur oil look?
How does ur coolant look?
Have u done an oil change since u've had the car?

Sometimes people sell cars on their last leg and do an oil change to a thick oil to try n cover up severe problems.

With all do respect, ur wifes step dad dont no shit about cars.

Every sound a motor makes should be smooth and in harmony with the rest of the parts. Any clicking, ticking, clanking, clunking, knocking or whatever is bad and only gonna get worse.

You can use a large screwdriver with the metal running from the tip all the way through to the end of the handle as a cheap but effective stethoscope to pin point exactly where a sound is coming from. You can listen to the bearing in pulleys, hear the rocker arms, hear the bearings in the water pump and all sorts of other parts.

Its possible u have 1 or more bad lifters. Its also possible u just need an oil change and a motor flush. Inspect the oil and change it if u already havnt. If u've already done an oil change, be prepared to have some work ahead, if the ticking is coming from below the lower intake. If the oil looks like coffee with cream in it, u got antifreeze in the oil.

Do it urself and save a shit load of money. Anybody with some mechanical skill, a basic set of tools and a Saturday can do this job.

Post back and let us know.

Well, Ok For Starters When The oil is like "Coffee" it because water is going into the oil first reason gasket set might be worn out it is cause by people put only water instead of antifreeze the gaskets get rusted then they tear up. Now if the oil is like "coffee looking" it might just be the gasket set. But if you notice that the coolant level goes down, it cause it going to one of your cylinders and it causing to misfire. But if that is true it might also be the heads maybe the person that had it before ran the car without antifreeze and heated the motor. And the bad thing about the malibu is that the heads are made of Alummin. So when the car is run without the proper antifreeze the head heat up and expand causing to swollen up and makes it easy for the water to get in the cylinders. I learn this because my malibu was doing the same but what I did was take the heads to a machine shop had them retorque them file them new half motor gasket set and labor for 700.00 where I live. And for the ticking sound I had that to the Mech. Said when he open the motor he said have of my lifters were loose that what was causing the ticking sound.

When my oil looked like coffee with cream, it was because of my lower intake gasket. First thing everybody says its the head gaskets and thats not always the case. The antifreeze and oil were mixing at 2 of the water jackets. I tore it the rest of the way down just to be sure the head gasket werent envolved and they were fine. So where does this "water" come from? I dont get what ur saying.

all the 3.1L's tick when cold...don't worry about it. It's not a lifter..may be piston slap

Change your oil, or at the very least check your oil and coolent level daily.

if your coolent level goes down it may be leaking, either internaly or externaly. if you oil level goes up on the dipstick. change your oil and coolent and have your lower intake manifold gasket replaced immediately with the new felpros. expect to pay $800.00 for a garage to do this.

Well, maybye it has a hair like crack and even if it that small it still can cause damage.
Well, Since you open the half of the motor might as well, retorque the heads new gasket sets,new thermostat, New thermostat sensor


Well, Like i said I got the head retorque for 150.00 for both and reseal , 300 for labor and 250 for gasket set and more parts for a total of 800.00 which the car is like new.

Well, All I can Say is take your lower intake parts to a machine shop to check if they are crack if they are that where the water is going to. By the way which cylinder is the water going to. If it is. If it not then where did you find the water.

ok.. ticking in the 2.8/3.1/3.4 litre engines is pretty much normal. The design of the valvetrain is inheritantly noisy.

Some vehs with self adjusting valves tick.

If your cooland looks like cappauchino, id bet money the lower intake manifold gaskets are gone.., the problem has been adressed many many times. Its the gaskets design. Simply put. The design is faulty, have the LIMG's changed and NEW bolts, and all should be well. Id reccomend a professional do this job. Unless you happen to be good with a wrench.. I dint do this job in my montana just because it is a PITA..

Good luck.
