The rods on the bottom end and if it`s that you will need a complete rebuild of the motor or get a rebuilt motor and use the old motor as your core deposit

Lifters tick. Rod bearings knock(typically the harder you mash the gas, the louder the knock). poor quality gas can do it if you need a tune-up.

I have a 1986 isuzu pickup it is a 2.3L 4cyl 5 speed 4x4, whenever it is given higher gas it tends to knock quite loudly, timing belt is fine and all fluids seem to be up where they should be.

the knock is most likely detonation or spontaneous combustion
it comes from incorrect air / fuel ratio, incorrect ignition timing,
incorrect rpm for the throttle setting
It is detrimental to the engine as the increased combustion temperatures will melt piston tops if allowed to persist unfixed
start by running the fault codes to find the problem area
( most likely a heated oxygen sensor (HO2S) in the exhaust manifold not reporting correctly to the ECM which controls the injector settings

Engine sounds like tek tek tek tek whenver it is running

Lifters & rockers in the head will wear over time and usually will require them to be adjusted. Thats really not that hard of a job if you are a Gear Head, and have a few basic tools. If not go spend some money with your local mechanic and have him adjust your lifters. As long as its more of a tick tick tick and not a knock, knock,knock. If its a knock, its in the lower part of the motor and its time for you to start looking for something else to drive. Good Luck!!

MY 2000 Montero Sport has a loud knocking when i Start it UP ESPECIALLY WHEN ITS COLD IT GOES AWAY AFTER IT WARMS UP

Sounds like a hydralic lifter issue. These lifters operate the cylinder valves and run off oil pressure. When the engine is cold and the oil is thick worn lifters tend to rattle. When the engine warms up, everything expands and the lifters stop rattling. There is no easy cure for this except replacing the lifters. Sorry....

86 ford lifters

i would suspect that your lifters are weak therefore the noise .or the rocker arms need adjustment i would try adjusting them to specs and see if that solves it, if not either the lifters are weak and need replaced or your cam lobes are worn. if you have to replace the lifters you must replace the cam as well . please rate this thanks

Upper engine knocking

I suggest if you know how to work on cars, adjusting your lifters, this is the common problem with those motors.
