m20 2.5 block

im getting like a clunk noise comming from block what can it be, i think it may be on its way out ..... do i replace this with a new engine or can i sort out the block?

Could be death rattle of many kinds! If it's coming from the block then it's probably a big end bearing gone...

You can replace with a short engine - depends on the damage - more details please!

Does the problem occur when:
Cold or hot or both?
On start up?
Low or high revs?
Low or high throttle opening?

Good luck...
