Still waiting to get my car back, its been almost 2 months now.

 

i know the feeling. but 2 months is still long. i did it myself, it was my first time doing more than brakes and oil changes, and i did it in 3 weeks with the help of a friend.

 

Well most of the 2 months has been simply sitting around waiting. Unfortunately when you're in Canada its hard to get parts for a mitsubishi out of the blue, simply getting a new sensor took a week.

 

I listened to the files and the one in the engine bay sounds similar to what I was describing in your other thread. I had the exact same sound when I installed my cam. It's gotta be the lifters but we never squeezed out any oil or reoiled the lifters. I could not hear too well on the vid since the car was not idling long enough to tell but it really sounds similar to what I experienced.

If I remember correctly I told you the mechanic took back off the valve cover, rechecked everything and then upon start up let the car run until the sounds went away. He did rev the engine gently a few times and I think it took like maybe 3-4mins for it to go away.

If it is your pistons then cool but sounds very similar to me.

Thx for the info WADADLIG OZ but what exactly did you mechanic do to get rid of the sound? I still need to do the compression check but I didn't have any time between work and school. I will try to do it ASAP.

 

Nothing really...he checked to make sure everything was tightened correctly. I never had to take my head off so I don't know if that had something to do with it. It's been a long while now but all I remember is him checking to make sure they were properly reinstalled.

After that he started it back up and I got that ticking sound. It gave me a sickly feeling for a while to think I might have screwed something up, but like I said he let it run for a while. first idling then revving the engine then idle again until it went away.

Besides the cam those were the only moving set of parts he touched. I hope for your all's sake it is not the pistons.

I wish someone could be here to check things out. Right now it's like an elimination process. Valvetrain, piston/wall clearance, ring improperly gapped??? The compression check should eliminate couple of those options. What really bothers me is why ValveMedic by Gunk made everything nice and quite for about 10mins??? Also, when I take off the oil cap while the engine is running the sound goes away???
I will wait for ambystome01

 

Maybe you're getting some higher crank case pressure created by the increase in compression. That's why the sound would dissapate when you remove the cap. Take the hose off the side of the valve cover and plug the intake side letting the valve cover vent to atmospher. Do this on the egr as well...

If the sound is gone then a simple easy fix would be a catch can.

Definately will know more when you do the compression test.

 

I just double checked that and actually when I take off the oil cap the noise is still there. I don't know what I was thinking.

 

compression test...

 

I got my car back, but I need at least a week to break it in.

 

Ok I can comment on the noise, my car doesn't have it.

 

which pistons did you get?
