Default Chrysler Sebring - Need Help / All suggestions welcome ????

Okay, Here it goes - I have a 1998 Chrysler Sebring Convertible 2.5L V6

About 14 months ago I took a small amount of the engine apart thinking I was going to learn how to figure out my old car. Then it sat for 12 months before I put it back together. Before I took it apart I was experiencing the following problem:

After a long trip usualy an hour and half or more, the car would loose power seeming like a fuel problem. Once I slowed down everytime I hit the gas the car slowed down even more and then stalled with the check engine soon light coming on. It acted as though it was either flooded or not getting any gas. After sitting for 45 minutes or more the car would run fine again for a while. The car also smelled like engine coolant every time I drove it ?

When I took it apart I found the following:

1.) Bad Thermostat - Shouldn't have caused the problem but replaced it anyway

2.) Oil in every spark plug tube (cylinder) about 1/2 or more of the tubes were full of oil (only in the plugs on the front valve cover) - I replaced all spark plugs and Valve cover gaskets (front and back)

3.) Replaced all spark plug wires

4.) Bad Intake Manifold gasket, which I replaced, along with a new throttle body gasket

5.) I also took off the fuel tank and replaced the fuel pump and the fuel filter.

6.) Upon puting it all back together it started 1st turn of the key even after sitting for 14 months. I took it for a diagnostic test and the tes tread that their was an EGR Valve Performance Problem ???

7.) I put a 16lb radiator cap on it 4 years ago - the manufaturer calls for a 14lb cap, could this cause a problem ?

Here are my current problems ?

1.) The car runs extremely hot, within a few minutes it is almost impossible to touch the hood prop in the engine compartment?

2.) The engine coolant smell is still very sweet and easy to detect?

3.) It does not seem like it has as much power as it used to, but perhaps tha tis because my other car has 280 horses v's the small pony that this one puts out.

4.) When the enginge runs you here a constant soft clicking sound ? sounds like it is coming from the intake manifold, but could be from below the manifold - like the head ??

5.) When I hit the gas the engine sounds raspy - not sure how else to explain that ??

6.) I think I am also burning too much fuel ?

* My first guess would be a bad head / head gasket - yet, my oil is great I was under the understanding that your oil would turn milky and throffy because coolant would escape into the engine oil - I have not seen that problem ?

* Any ideas ?? Is there a test that I can perform to find out if I do have a bad head / head gasket without taking the top end of the engine back out of it ??

Any help would be greatly appreciated

Ok I just wrote a long passage and erased it on accident. So I'm keeping this short see a shop and have them perform a block test we charge 27.99 to do this. It detects exhast and combustion gases in the coolant. It's not infaliable but it's the most precise way to tell then a tear down. A head gasket can fail in many places not always leaving water in the oil the only way to get water in the oil is failure between a coolant and oil port are week pistons rings pushing water threw the motor while hydro locking.

Signs of a blown head gasket
1. oil in water
2. water in oil
3. while car is cold take radiator cap off start he car does coolant immediatly over flow the radiator if yes then you most likely have a damaged head gasket a craked head or cracked block the block test will confirm 1 of the 3.

Your perticular car is extremly seceptable to air pockets as well and the bleeder screw in the center of the engine likes to leak creating these pockets.

The bad news in a 2.5L it's not hard to pop the gasket it can happen in just 1 over heating of the car, and to do your head job correctly at a professional shop it's about $3800 you can half a** it do it your self or get joe blows shop to do a half A** job for much less but watch out you get what you pay for.

I was going to say what lautin said, does your exhaust smell sweet or is there a puff of white smoke when you take off, which would indicate antifreeze vaporizing through the exhaust?

lautinjr is right on.

He did miss one that you mentioned, a sweet smell around the car. You can get coolant in the exhaust and you will see constant vapor from the tail pipe and smell it.

If you are smelling coolant and their are no external leaks, then the head gasket is most likely gone.

Thank You for your responses - I didn't know it was so innexpensive to get a block test, when you say it is not infaliable how reliable is the test ?? someone today mentioned doing a compression test ? is that the same thing ? They said it involved removing the spark plugs and testing the compression from each cyclinder ? Is that more expensive - is it a more or less accurate test or does it even test for the same thing ?? Thanks Richard

A compression test CAN show a problem but it would need to be pretty extreme. A block test is a much better method.

You can remove the plugs while the engine is warm and watch for steam from the plug holes. If you are getting a sweet smell in the exhaust, then you will likely see steam from the plug holes.

Mr car guy is dead on. A compression test will only leak down fast enough to show if it's major and if it was that bad she would barely run from all the water in the cylinder. If it fails the block test then it's definetly bad but a car can have a bad gasket and still pass depending on wear it's leaking in your case it's overheating so it will pass or fail and be pretty accurate. In a shop we use this method to determine if more damage has occured before we make a costly repair and have a customer pissed because we changed his leaking water pump and now it still overheats.

Just pay to have it done if it fails then you know bad headgasket craked block or head.

And remeber your next car don't let it overheat and if you just need to get around the block that is the worst thing to hjappen to a car and there tolerance for it isn't like it used to be on older cars. They don't make them like they used to but actually there better when you keep them up properly.

Thanks Again guys,

Just to be clear though - I probably misled you when I said it is running hot.

That is more of an assumption than anything else. Before I replaced a lot of the parts I discussed initialy the car never showed that it was overheating on the cars display panel.

I replaced the Thermostat anyway because I was hoping that the origional one was broken and by replacing it the engine would tell me it was running hot or cold.

I still get the same reading that I used to get on the cars internal tempreture gauge.

I assumed that the engine is running hot because of the coolant smell and because it is extremely hot under the hood after a short trip ??

Thanks For the help - I think more than anything else these threads have helped me to realize that I am not cut out for working on cars - I should stick to my desk job and pay the pro's to do what they do
