To be honest, when i took off the head, you can see how good the pistons looked that i thought that the person who had the car before me had done some work on them, so i left them alone.
The car came to me as a non runner due to rattly engine. The engine came from a scapped car which wasnt heard running but the guy could not be bothered once he heard the rattling and sold the car on.
Initially a good old oil change sorted the problem but it was very juicy and smelled of unburnt fuel. I checked the timing chain and the timing was one tooth out. Installed a new timing chain and set up timing thanks to a how 2 fit chains guide on here.
Still pungent and smelly on running and the front lambda sensor stayed at lean instead of fluctuating lean/rich on the opcom. So i renewed that too.
Lambda reading started to fluctuate but still pungent and plugs soon blacked up. So off came the head!!!
Filled all the exhaust ports with water and valve 8 just let it all out. So changed all the valves, stem seals and gaskets.
That is now where i am at and scratching my head
