s52 timing.. im stumped

[middlegati]

hey all, i redid vanos. i had to remove the locking blocks that i had originally installed because it was preventing me from removing vanos..and well when i went to take the vanos off i turned the sprocket and the intake cam turned... the exhaust did not.. i had the flywheel lock pin installed, so i reinstalled everything and checked it, the exhaust cam is TDC and the locking block sits fine.. the intake is not.. this is where im stumped.. how can i re set the timing for intake? ive looked all over, do i just get a 24mm wrench and turn the intake cam?

thanks.

You need to loosen the bolts holding the sprockets on to the exhaust cam and install the VANOS unit, then you can get an adjustable wrench on the back of the intake cam and turn it to TDC, install the cam lock plate, tighten the exhaust cam sprocket, and you're good to go.

thank you! i got the intake cam aligned and then attempted to seat the locking blocks but they did not seat properly.. do they need to seat perfect? ive read both sides some say yes some say no..i adjusted the exhaust cam to get them to sit perfect but then the holes for the exhaust sprocket do not line up, if i adjust the sprocket will it through my timing out ? if the motor is TDC?

also now my exhaust cam is not TDC when the crank pulley is set to TDC.. i didnt change the exhaust cam from original postion.. im super confused. im going to remove spark plug and check TDC that way..
