Hey guys

My friend has a problem with his 1G Eclipse. I drove it today to try and diagnose the problem but I am unsure of what the problem is.

When you drive the car and floor the gas pedal the revs do not increase much beyond 2500 RPM and the car has virtually no power. The turbo spools up just fine and does not have excessive play in the shaft. When flooring the gas at 2500 RPM in 2nd gear the turbo builds plenty of boost. The stock gauge read around 12-13 psi at this point.

Also there is a distinct ticking coming from under the valve cover. It sounds just like a Honda that really needs a valve adjustment. This seems odd to me b/c I thought the 1G 4G63 had roller rockers and hydraulic lifters which are self-adjusting.

Any ideas would be great here.

Thanks a lot

 

Hey

Here is what is bugging me. The car will not really rev past 2500-3000 RPM. It almost like the car is trying to go up a *very* steep hill or like you are driving the car at full throttle with the brake pedal pressed almost to the floor. It is like the car is fighting itself to get going.

You can hear the turbo building boost and when you shift you definitely hear the BOV. Any ideas as the the above symptom I just pointed out?

The ticking in the valve train sounds a bit abnormal. I know you said the 1Gs tick but this is almost a banging rather than normal valvetrain noise. It sounds like a diesel powered Mercedes Benz!

Thanks for your help

 

It is interesting that you point that out. I do remember the brakes feeling a bit funky. Also when the car is not moving (like in neutral or with the clutch pressed) the car revs up just fine and sounds normal. It only has this problem when you are trying to accelerate. I will check the brakes ASAP.

Thanks for your advice

 

My thoughts exactly If you rev the engine can you notice a large amount of air coming somewhere out of the
piping? How well does it accelerate TO 3000?
