I bought a 87 4x4 22r today and it has a horrible knock or clanging noise. I removed the head cover and didnt see anything unusual. I have removed all the bolts from the oil pan but I cant get the pan out. I think I have to loosen the motor mount bolts and jack up the motor and tranny. Is there anything I should be doing diferent or I should be looking for? I drained all the oil and didnt see any metal shavings or anything. Someone said it could be the timing chain clanking against the cover, if this was true, would the chain have a lot of slack in it, or how could I check it?



horrible knock or clanging noise.

there is nothing in a 22re that should make that kind of sound.
the only time I have heard what you are saying. If you are being honest is the 3rd rod bearing.
the motor that I heard that from the rod bearing was pretty much gone.
spun on the crank. I am just getting ready to send it to the shop for a crank grind, maybe a new rod.

chain sounds just like a chain running over a corner a metallic buzzing sound.

valves... yep diesel motor under a load.

most any 22re ticks a bit.. but it is just a diesel clackity sound.


you can also pull all the belts off and start it and see if the sound is still there. maybe it is an accessory that is making the sound.


good luck,, but if I am reading what you wrote, correctly I think that you will find number 3 rod bearing bad or gone.
