Have someone that knows well about cars look at it.. DO NOT drive the car like this..if its a worn crank saft there is still hope. What you have to do is check the bearings (in the oil pan) Ceck to see if they are worn or loose, not sure how to on the gs (remove the bearings and check them do not mix em up, put them in th order they were. If you see the metal pieces that go between the cam and beatings scratched, broken aka..the cam is damaged. Take out resurface, new bearings and metals. Not as expensive as it sounds (here in the us machine shops do it for around 150 depending on where you go and if you do the work yourself) Ten well put evetything back the way it should and walla..knocking gone. OR you IF it is this, you can invest on a klde or klze much much more fun (so ive eard) OH and well make sure you rule out everything else of course. Seems to me it may be the engine itself since you replaces tensioner. Another thing, run the car with all the belts off( not daily driving) and check to see if you still hear the knocking, could be the bearings on one of your pulleys. Sorry fot this long post, just that all of these have happened to me, once it was the power steering pulley bearings the other time it was water pump and once it really was the bearings on the engine (cavalier)

welli know its not the lower end bearings. they are brand new. and when i built the motor i chaecked all the clearances very carefully. i ran the motor yesterday and after it warmed up the knocking went away. but the i shut it off and it wouldnet start back untill it cooled some. but then it started right away. i'm chacngeing the oil and plugs again today. oh and since i rebuilt this engine it has only ran about 45 min all together.

That sounds like bearings. Your crank is probably worn causing you to prematurely wear out bearings. I put 2 sets in last summer. The first set was my first time doing them so I figured I may have done it wrong, the second set I know 100% for sure they were done right and within hours it started doing the same thing again. I thought the knocking went away after it warmed up, but if I went under the car, I could still hear it very faintly so I knew it was still there. If I can give a recomendation for changing bearings, pull the motor, put it upside down and put the motor back in. It's faster and easier than trying to do it laying on your back underneath the car

my recent knocking came from the water pump.. sounded almost like a rod knock

but if you're not leaking anything then it prolly isnt that.

well i knocking finally went away. the tensioner did it i think. i warmed the engine up and it faded away and hasnt came back. now my oil pan is leaking. do you use cork gaskets or just silicon? this sucks now because i just changed the oil today.
