Hi all, 

I`m currently replacing the cam belt, water pump and oil seals on a good running 907 to put in my eclat. so a little overhaul. 
 but i`m just wondering what the best way to remove the cam sprockets and replace the oil seals?  I`ve currently got the cambelt,  and cam pulleys off at tdc, and replaced the water pump, Ive had the sprockets zip tied together so that I dont move them unexpectedly, but it won`t be enough to keep them in place whilst I undo the sprocket bolts. any tips on doing this and on cam seal replacement afterwards? 
cheers,


Mark

Don't.

 

To get the seals in you really need to remove the cam shafts, to do that you need to remove the cam carrier. You can get the seals out (screw into the seal etc) but to put them in you really need to drift them in perfectly perpendicular to the cam shaft.

ok, i guess i`ll leave it then, i`m not sure how bad they are leaking, but I dont have the time for a full rebuild at the mo.   what about rear main seal?  worth doing I guess as theres no getting at that when the engine is in the car?

ta,

Mark
