MITSUBISHI ECLIPSE ENGINE PROBLEM

2002 Mitsubishi Eclipse • 156,000 miles

Hello,

My car has been out of commission and sitting up for 9 months due to leaving me stranded and not cranking anymore. Why after changing my timing belt, I emmidiately start having problems with bad noise from egine. I can not accelerate anything like I used to. Car makes clacking noise and looses power and velocity after 55 miles per hour which enables me to speed up and pass. Also, after running it for around 70 miles bubbling noise appears from overflow but engine temperature level remains somewhat the same. Lastly, after running it for a short period of time oil light flickers when I start slowing down or come to a complete stop.

Here is what I have done since I changed timming belt and tensioner. I changed starter because starter was giving me problems. I changed alternator because relay was bad on my other. I changed oil filter and oil to a 10W 40 weight. I changed 2 bad valves and also changed 4 lifters to # 3 cylinder. The only thing I have not done is flush out my radiator.

After all of these changes my car is still running bad and giving me problems!

Please help!

Is the Malfunction Indicator Light showing and did you check for trouble codes?
Recheck the timing belt. It could have been installed out of time.
Have the oil pressure tested.

Hi,

Thanks for your emmediate responce! The check engine light always stays on without any problem occuring. However, I have sent car to get scanned and the trouble codes showed up of that being starter and alternaator which were both bad but also have already replaced.

The timing belt seemed to have been put in right eventhough I did have problems keeping car on at times and then mechanic had to adjusted timing from the engine so thaat caar could stay on and not shut down when I come to a red light or any stops. At the present time my rpms readings are above normal for this reaason. The oil pressure is really good!

Your help is really very much appreciated but, how does your answer help my car gain power and speed up as well as stop that loud noice comming from top of the engine?

Thanks,

Those are my initial suggestions and if the timing belt was installed incorrectly, redoing the job would help to get the engine back to normal operations.

Engine light staying on means a fault is present and understanding what it is would help to diagnose the probem.
What were the trouble codes retrieved and are there still any trouble codes? I need to have the EXACT codes.

How does the noise sound like and does it increase in level with engine rom?

I will get this done today!

Thank you thank you so much for your expert help! I will get back with you today. However, can the timing belt poping off cause damage to engine where I have to change 2 bad valves and 4 lifters? Also, it seems kind of crazy how before my timing belt went bad I never had any of these problems and all of a sudden all these other problems have occured!

One more thing that I fail to mention that might could help matters out. The other night I went to crank my car up and it sounded like something was fallen apart inside the hood but after a few seconds whatever it was all of sudden stopped or broke off because when I stopped to take a look I did not see anything.

I will retrieve the exact codes for you today!

Thanks,

You mentioned replacing the timing belt but did not specify that the belt broke prior to replacement. That can mean a lot of difference.

The engine is an inteference engine and when the timing breaks, it can damage the valves, usually all cylinders would be affected.

As to the noise which suddenly disappears, too bad we are in no position to make any comments because we do not know where the source is and what is causing it.

Have the engine compression tested if possible.

Hi,

I was not able to find any car shops open today being the 31st. However, tomorrow I will go and run a compression test on all cylinders and will also do a scan to find out what codes it brings up.

Do you not think that it is a slight chance the the timing is off and is the reason why oil light is coming on after driving for a while? Also, it might be the reason why I am not able to have velocity after 55 mph. Remember the timing was adjsted a bit high so that the car quit cutting off on me.

Please let me know your feedback asap!

Have a happy New Year!

Yes, it is possible the timing belt is not installed correctly and as to the oil light coming on, it could be the oil strainer is clogged. Is engine heavily sludged?
It could also be due to a bad oil pressure switch.

It is not the timing that is adjusted high but rather the idling speed if I am not wrong.

Hi,

Ok here is what seems to be going on. After checking out if the the spark plugs were burning correctly, the mechanic decided to also check the coils out and everything seemed to be ok. He than decided to take the timing belt cover off to look if the timing belt was put on wrong. He turned on the motor only and he put a gun with a light to see if the timing belt was off. It turned out that the mark where he marked with the chalk was one tooth off. He told me that once he adjusts it back to it's mark than I wil have the power and velocity that I need. He also had to bring down the RPM's so that the vehicle could idle better and calmer. He went from 1000 to 800 RPM's.

The next thing he did is that he looked underneath the timing belt where there is another small belt that controls the oil pressure and shoots oil to the valves and lifters and that belt was also istalled wrong. He proved it to me by putting in my hand lots of shavings from that belt that was just installed one week ago and told me that if I continue running my car like it is, than what would happen is that I am going to have to replace my motor really soon! He also added that this is the reason for that bad knocking on the lifters and valves because that belt was not putting out the oil that the valves and lifters needed therefore that knocking that I was hearing was because lack of oil which made the lifters and valves dry out.

Tomorrow we are going to buy a new small belt to better the oil pressure and he is going to reinstall my timing belt correctly!

He said that this should cure everything up!

What is your expert take on all this? What would you add to this?

Awaiting a reply soon!

That was my initial take on this, an error in the timing balancer/oil pump belt instalation.

The explanation on the problem is correct and once the belts are in position, the engine should be running well again.
