Mitsubishi's 4M40 or 4D56?

[heightdeprived]

Yan din ang sabi ng isang chief mechanic dito sa mitsu casa. Mas gusto daw niya ang 4D56 kasi belt driven kaya mas tahimik. Ang 4M40 at 4M41 ay chain driven, tahimik sa simula, pero pag nagtagal na, mga 80-100k kms, mas maingay na kesa 4D56. Madali naman daw magpalit ng belt.

Ang ayoko lang sa 4D56 ay mas-mausok at mas mahina ang power (older generation).

if you think your 4M40 has become noisier than it was when it was new, try checking the timing chain tensioners, perhaps those timing chain tensioners require replacement ... HTH
