cylinder head project v1.1...

couple of months back bought a cylinder head from SIC forumer... complete set including valve springs, rocker arms, and camshaft... plans to rebuild this valvetrain nicely hoping to optimize the cylinder head flow efficiency...

took my sweet time dismantling the parts out one by one... as i didnt have valve spring compressor, i took the cylinder head to my mechanic to remove it... he taught me a very simple and effective way of removing the valve spring... put the cylinder head on a wooden block... position a spark plug opener on top of the valve spring... use a hammer to knock on it until the valve spring retainers come loose (fly out)...

another important thing is to document each and every valve with respect to their cylinder... no idea why but my mechanic said each valve is unique to its valve seat at the cylinder head...



bought some steel brush with some ron97 shell fuel as detergent... lolz...



after some hard cleaning job... here is the outcome... some stubborn stain still remains at hard to reach area... have to buy more fuel and soak the whole cylinder head with petrol overnight to remove the stubborn stain...





next up... still deciding whether i should send it to professional for port and polish job or jz DIY... this is also a good chance for me to learn how to do top overhaul myself...

to be continued...
