I know this topic has been brought up alot but all the examples hasnt really touched on my probs in a nutshell!!!

My Sunny in the morning blows an incredible amount of smoke when i start it up and when reving increases as the RPM's do aswell, this dies down after awhile but it still continues to blow smoke during the daily driving. Its not blue smoke, its light white-grey in the morning and grey-black when engine at operating temp...

Am i right in stating the my piston rings have gone therefore letting oil in the cylinder chamber or my valve stem seals therefore getting in thru the rockers??

Would it be worth fixing this tired A15 (350 000k old) or purchasing a recod one as im moderatley modifing the wagon....

Any post i put on here seems to be that i have a problem! DAMN MY DATSUN!!!!!

Cheers
Dave
