Hey guys. My isuzu 2.3 is knocking. I don't know if its like a bearing or rod or if maybe the oil pump is shot and its not getting oil? Can anyone give me any input as to if their is any type of common issue with the 2.3 having a knock issue? its an 93 isuzu pickup so it has the 88-95 2.3 in it. If it could be because its not getting oil, can someone tell me where the oil pump is located on these trucks?

Thanks guys!!

my 2.3L took a shit on me a couple years ago. i replaced the head twice. then it took a huge deuce again. i adjusted the valves and the timing and it seemed to be running fine, just not as much power. i checked the fuel pump, and it was just about to shit. so i put in an electric fuel pump, and it's been running good for a few months now.

when i bought it, everyone i talked to said isuzus are very reliable, i'd drive it anywhere anytime. ya right. everytime i see a post about an isuzu, it's an engine problem most of the time.

you can add add a little bit of transmission fluid and it will quit knocking,but if its a big knocking i'd check your oil sump,oil pump,and you valves.

yes that is correct...you have to pull the motor on it because of the X-member...I took the cheap way out when I had mine and braced it in a few places first and then cut it out...then once that was finished welded it back and took the other braces out...I dont know if that is a bad way to do it or not but I never had any problems from it anyway
