Hello,
Okay, to catch you guys up.
My girlfriend has been driving our new Montero for almost a week now. Its a 2001 with almost 169k miles on it. When we test drove the car it had a very slight noise in the head. I imagine it hadnt been driven much. Now my girlfriend has been driving the car for over a week now and the sound is VERY loud and it seem to be getting worse. I have done my research and I feel like I can fix the car but the problem is I cant seem to find the exact issue.
VLA's (valva lash adjuster) -- I tried to bleed down the VLA's and after 30 tries with no luck I gave up. Plus it sounds so bad Im affraid im hurting the motor.
Here is a link I found for the process Mitsubishi Tech - Minute Mod: The 5 Minute Lifter Noise Fix
As I slowly rev up the engine it seems to be the worst from idle to about 2200rpm then it almost goes away as I rev up the motor. However as soon as I release the gas and the revs drop to idle the noise comes back again. The noise never seems to go away.... I dont think its a bearing since I can rev the motor and it goes away.
I have heard of the timing belt causing loud knocking or slaping sounds, any input?
After trying the bleed down the VLA's with minimal results I poped the hood to make sure the noise was from the VLA's and it seems that the noise is coming from the front half of the motor but its so loud I cant narrow it down past that. It sounds like a loud knocking or ticking. I do mean LOUD. It could be any thing in the fornt of the motor. Im pretty sure its the VLA's but not positive. Its alot for me to open up an engine on an assumption.
I am going to change the oil to mobil 1 20w-50 and a good filter after a flush. Im also going to sea foam the motor to try to burn off any crud in the VLA's. Hopefully this works, if not then Its back to square one. or its time to just crack her open.
Please help me narrow down this problem, my girlfriend is a single mother with a 6 year old and she needs a reliable mode of transportation.
Thanks
Alex R.
