4m40 knocking sound (acceleration)
Mga mitsubishi experts and pajero owners...
My 2003 pajero has a knocking sound (tac-tac-tac), continously and loudly upon pressing the accelerator pedal in a rush (PA-BIGLA).. as early up 1.5 rpm, the knocking would start and never stop... BUT (weird part)... if I will accelerate it slowly.. kahit up to 3RPM, walang knocking sound...
I had two mechanics checked, they can't diagnose the problem.., ang sabi lang OVERHAUL daw kailangan... huhuhu...
any help will be appreciated... thanks
Re: 4m40 knocking sound (acceleration)
may pahabol tanong pa ako...
kapag palitan natin ang mga shocks ng 2003 pajero to GAS type, nawawala po ba ang options ng Soft-Moderate-Hard? At patay na rin ang ilaw ng tire sensor ko...
Alanganin ko dalhin sa CASA kasi I'm sure patay ako sa gastos....
any help anyone?

check mo muna timing, valve clearance, pede rin fuel knock yan, check for air in the fuel line. finally mag pa compression test ka. if all checks out baka katok na yan ng conrod bearing. how many kms na tinakbo?

If your mechanics has an automotive stetoscope and technically knows different engine sound, they can easily identify and locate that knocking sound. Saan po ba location nyo? Kung malapit lang sa amin I'll identify it for you for FREE of charge

may ganyan din ako dating problema. sabi sakin nagloloko daw yung EGR ko. ginawa ng mekaniko pinasakan ng pako yung vaccuum tube na nagcoconnect ng EGR at intercooler. nawala agad yung tunog. try mo po baka sakali gumana.

what do you mean "pinasakan ng pako"? Is it normal to have dark smoke (upon rev) coming from the vacuum tube (if not connected with the intercooler)?
How do I check if the intercooler is still functionable?
