You don't say how many miles or give a service
history, but, that said I would check the timing belt and
tensioner. When tensioner goes bad is often is reported as a loud knock
or tick. Usually most evident at low RPMs. Another low cost try is to
use a can of seafoam in the oil now, run it a few miles, then change it
for a high detergent, low viscousity oil and drive it a while to see if
the lifters clean up. engine tick is very common, generally due to
lifters oil passages getting sludged up a little for 2nd gen 3.2l's

First of all, you must state WHY you are changing the timing belt. If you are changing the belt due to a scheduled maintenance, then we would have to go from there, but if you are replacing a belt that has broken---well my friend------I am here to tell you that you have what is called an "Interference Engine". An Interference Engine is an engine that does not have adequate clearance between the pistons and the valves in case of a timing belt failure. Lacking this adequate clearance, in the case of a timing belt failure, the pistons "Interfere" with the valves, causing them to bend. This "Knocking" noise that you hear is more than likely the pistons banging against bent or broken valves. This can be diagnosed by doing a compression test. However, when seeking advice, next time , give the history of the vehicle prior to the parts exchange. It can help narrow your situation to the problem by 90 + %. MR. VINCENT. ASE MASTER TECH
I am assuming your rodeo has the V-6 engine, like the one I used to own. Your drain plug is located on the engine oil pan, along the rear side of the oil pan. this is located in the center of your rodeo, about 3 feet back from the bumper!
Sounds like your Rodeo was taken to the circus. No warranty on that new motor? I need to know where the sound is coming from. Top, bottom, front rear or what. Is it a tapping or hard loud knocking??? Let me know and I will try to help you out. Raz
Sorry you did finish you sentence. Grab the fan blade (engine off of course) and see if you can move it back and forth. A lot of play may be a bad and knocking fan clutch. Or a worn out water pump. Move it if you can and see where the play is coming from.
pull the engine oil dip stick out and see the oil in the sun, if you see little shini particles like metal, then the engine need an ovehaul, but most likelly you need another engine. or rebuilt the one is in the isuzu
