Hey, and it just occurred to me -
A one way valve (for God's sake fit it the right way round!) costs a fiver, a metre or so of leak-off pipe about the same, and glow plugs cost what glow plugs cost, and don't last forever, and all of this is DIY, no labour charges!!
By the way, does your car have an EGR system fitted? If so, find it and blank it off at the exhaust manifold. That EGR thing kills power and economy, and is probably the main cause of gruesome messes in the inlet manifold.
Ask some of the experts on this engine about EGRs and disabling them.
