The original daewootech forum

So I tore into the head, and didnt really find anything that was obviously wrong, or at least didnt look too wrong until closer and further inspection. I was looking at the wear patterns on the camshafts for both the intake and exhaust and noticed they were different from cam to cam. The intake cam ...

So I drove it over 600 miles with the noise that I had. The noise got progressively worse and louder. I stopped driving it because it was getting worse and the check engine light had come on. I have ordered some top end components such as 2 valves, 2 lifters, and a valve cover. I will be breaking in...

So did a repair shop do the repairs to the timing belt issue. If so, was the car making the noise when they gave it back to you? I cant imagine a repair shop would give a customer their car back if the engine was making the noise you described. On an important note: ANYTIME the Cylinder head is remo...

Another test I performed was I shorted each comb chambers to verify if the noise either continued or subsided. Supposedly, if there is no combustion, and the noise goes away, then its the bottom end (piston slap or rod knock). If the noise continued, then its more than likely not the bottom end and ...

So I did a search on "Engine Knock Diagnosis" on my toolbar and found this interesting read. I think this could be valuable information for those owning woos since this can be commonplace. [/url]http://remanufactured-engines.com/page4.htm So I did a couple of checks and this is what I found. 1. I re...

Thanks for the reply and the outside of the box thinking. However I am absolutely positive that this noise is coming from inside the head. #1 You can feel the knock on the head #2 Sound is more prevelant from the Intake Manifold-maybe cuz its aluminum its acting like a speaker for the noise. I think...

Thanks for everyones replies. I know this is an older post, but I havent had time to tinker with it lately. I just changed the oil and filter, from 5w30 to 10w30 and it seems to have gotten worse. It has a ticking or rattle sound near the head (like its valvetrain), then when you raise the rpm's qui...

So if I had the tech service manual for the 2.0L, I could basically follow that when working on the 2.2L and not get into too much trouble?

The 2.0L is better in what way?

I have a 99 Leganza SE with a 2.2L engine. I just got my hands on a service manual for these Daewoo's. Problem is the service manual is for a DOHC 2.0L engine. I was looking for one on a 2.2L engine. Is the 2.0L engine the same as the 2.2L? Is all the data and information directly related and can be...

Thanks for the replies. The car runs just fine. Just makes that knocking (rattle) sound, and I am afraid to keep driving it for fear that I will do more damage than what is going on in there currently. So when I go to rip the valve cover off is there anything I should be looking for? If nothing foun...

Hello and new to forum. Just picked up a mechanics special 99 Leganza with a 2.2L for dirt cheap. There is a slight intermittent knocking (rattle) sound coming from the Cylinder head, (I confirmed this with a stethoscope). The noise is present when engine is cold and at higher RPM's, but not through...
