i just came across this thread (http://www.xoutpost.com/bmw-sav-foru...christmas.html)...

i wonder, should one go for the valve seals, can that job be combined with this collabsible tube job? get two things resolved in one shot...

and i haven't seen much info on N62 chain guides, that was plaqueing the M62 engine - would it be feasible to consider the chain guides replacement at the same time?

obviously there is an aftermarket modified coolant pipe for the leak...
there is NO factory or aftermarket modification for the valve seals...

Is there anything for the chain guides?

what else should be considered a ticking time bomb that can be addressed once the open heart surgery commences??
