I think this is the big one. My '98 has a vicious clacking sound in the engine. I took the belt off and confirmed that it is in the engine itself and not the accessories. Using a stethescope (sp?) it is louder in the back, drivers corner of the block. It sounds like a sharp clacking sound and seems to be high in the engine. It seems to loud or deep to be valve noise and has the rythme of a connecting rod bearing. It looks like the engine will have to come out.

I have lots of questions that need to be answered. Should I even tackle a job like this on a 10 year old car? Should I drop in a used engine? Should I repair the old 230,000 kM engine?

I am open for suggestions and would appreciate any input.

What is the oil pressure reading?
Any signs of bearing failure in the oil?
Does the car seem to idle well or does it have trouble?

Almost sounds like you are describing a collapsed lifter.

Bill, Thanks for the reply.

The oil pressure is good. The car is ready for an oil change so the oil isn't very clean, but I don't see anything unusual either. I haven't drained it yet. The car starts and idles fine. The clacking sound is generally consistent but every once and awhile, it will quite down for a few seconds. Can you diagnose a "collapsed lifter" by examining the top of the head? I have never seen anything like this, but the sound is coming from the right area.

fwiw a new engine is cheap from a yard. but i'd diag your problem as it'* probably cheaper and easier then buying a new engine...but i suppose that depends on how handy you are.
