190e 2.5 16v - i stripped the front of the engine down to replace broken lower guide rail - all sorted, now started the rebuild.

couple questions/confirmation - is this what i need to do....?

first i plan on rotating the engine till the cylinder at the front is at the top of the compression stroke - i plan on doing this this by inserting a thin wooded dowel into the spark plug hole.

then i need to place the cams in their bores, roughly aligning the small holes in the sprockets - then bolt them down. once bolted down, realign the holes if needed

then run the chain round the cam sprockets, connect using link.

fit front engine plate

because i am at tdc at this point i can re-install the distributor body, alining the rotor arm to the notch in the body....??

does this all sound right, am i missing anything obvious...??

dont have any references in terms of current timing/internal engine position statusto go by as the engine was apart from some time....

just after some confirmation that i'm doing it right really.....

thanks all

While you are at it, don't forget to install the chain tensioner before you decide to rotate the engine by hand after you have it all aligned. I know from experience that can be costly. Also, you might want to check to see if the chain tensioner you have is the new and improved one. Jim
