Hey everybody, it cant be said enough, im very pleased by the information u guys are giving me, for me its an super cool experiance to rebuild this engine, althrough its my very first time rebuilding an car engine, its cool to do an 16V engine !, learning so much too !, so
i didnt had any time to take the engine block appart and check the piston rings, but i did take all the valves from the head and checked them, there is very very very little wear on the valves them self but alot of carbon (engine definatly burned A LOT of oil !!!!), now im kind of looking for tolerance measure numbers !, when the valves are in the valve guides, there is an Very Small amount of play that ive noticed, and since the valve rods barely has any wear on them, should i replace the valve guide with the Original size ? (mercedes EPC shows repair sizes but arent those not bigger ?)
for sure im going to replace the valve seals ! but im not sure about the tolorance measuring on the valves them self. should there be any noticeble play that i can feel or just NONE !?
im working with an workshop book from an 2.3-16V engine, theres info in there but can i thrust the info from that book with my 2.5-16V or is there diffrents in them ?
also need to know this for the Nm torques to tighten the bolts of the piston rods, crankcase bolts, head bolts stuff like that,
here are a few pictures of how the valves and the valve seats in the head looked like
thanks everyone
