engine makes chain hitting block noise?

[91ka]

engine makes chain hitting block noise? im guessing but it sounds like its coming from the middle of the block. recently its becoming louder and more consistant.. recently checked the upper tensioner and the side guide (no upper guide) and their fine.

it makes this noise especially after the motor being run for a period of time. it doesnt make this sound when gas is applied although it does makes the sound right after i let go of the gas pedal. (basically makes this noise COUPLE TIMES in idle and everytime i shift from 1st to 2nd.)

anyone else experience a simliar problem like this?

Depending on the km, you may need new timing chain.

or it could be low oil pressure.
