Is it low on power, indicates a worn ring set, is it difficult to start in the morning?
Also what is the mileage , 660cc right?
What is the oil you use, a thicker oil may help a bit
You can go two ways about this
Either way do a compression test - if low
1. Take the head out, check the bore, rings
Replace only ring set, run for 30 40k more if it maintains adequate compression
2. Or run as is, im sure with your given data it can do 30000k odd more, till it gets hard to start and the engine is badly worn,
Failing emissions etc,
do a full rebuild including the bore and the bearings etc
Or put a new recon engine provided you know the mileage.
