Blue smoke indicates oil being burned. - Yup
If the oil light came on while the engine is running and the oil level is at full, you either have a faulty oil pressure sensor system (wire, sender or connection), faulty oil pump or a pressure drop due to a leak. - Nope, this is not what's happening. Oil indication is normal.
Clacking is possibly insufficient oil to the valve train. - Ahhhh! so, even with the oil topped up, if this is still happening, what may lead to that?
The battery seeming as if it is run down may be from the ignition switch staying on or multiple starts during servicing.
Loss of power can be a faulty piston ring. - Will a compression test reveal that?
Open your radiator cap and look for an engine oil residue. - Did that; and there appears to be none.
Use a gauge to check each cylinder's compression. - Actually waiting on someone to facilitate.
Check the engine oil pressure. - How's that done... other than the dashboard indication?
Check you battery voltage and charge it to resting votage of about 13.0+ volts. - battery checks fine.
Maybe I didn't explain myself clearly... Just because the oil pressure light stays off doesn't mean that all the components in an engine that need oil are getting. If that light comes on when the engine is running it is usually too late. It needed oil way before that light came on.rayj wrote:Errr.... maybe I did not explain it properly - it was only the day it shutdown for that an oil light came on and oil had to be added ...and serviced every 10,000 km.
You're right though, something doesn't add up.
Leaving it parked up for now; until I can get some more time to look into it.

Not to be a burden... Did anyone identify the root cause of the problem i.e. what caused the ring to stick or why it was stuck.... Cause there is a chance that the same problem can reoccur even after it is fixed.rayj wrote:So.... just in case anyone was still interested....
I finally got back the vehicle a few weeks ago. Getting the parts was the main issue. The ring-sets for the pistons were particularly difficult. Anyways, some damage was done. Apparently a fouled scraper ring (did I get that right?) on one piston caused it, AND some piston scorching. Re-sleeved and still breaking it out; but to me: so far so good, engine-wise.
Since that time I've been hearing that mine is not as uncommon as I thought.... apparently there's been a number of similar complaints and disgruntled owners.

Glad to hear you got it fixed... I know you don't want a repeat
