Cam Timing

[David Greenwood]

Recently my 172 cup cam belt plastic guide destroyed itself, resulting in bent valves, I have had head done all new vales and gaskets and boltes etc £280. But the inlet cam gear is a weird one it has a timing mark on it but there isnt any apparent marks on tha cam cover to align it with?? Do I need to follow any particular instructions when timing the cams , if so can anyone email me with some good tech info.

Cheers

Dave

Theres two oil seals you need to pop out to find the timing holes, Pin them like you would a normnal car (although apparantly theres some special tools for this engine ?????) and then replace the seals with new ones once you've timed it up

There is a selection of special tools needed and i would not even attempt the job without a complete understanding of the job at hand and the tools. Get hold of the manual and have a read.

Those are the tools needed and a brief guide.

Its not a hard job, but easy to screw up, as evident from the number of botched jobs i spend my time fixing.

right great !! just talkin to burp as well he's giving me info i don't need pulley lockin tool unless im takin the pulleys or cams out, i only want to do the belt so just need the timing kit.....

 

[BenR]

To do the cam timing procedure properly you have to loosen the cam pulleys.

 

[ginna]

ok will go into renault tommoro with the part numbers and price the pulley locking kit up then !!!

 

[ginna]

so this is the mot 1509 ? whats the mot 1509-1 ?

 

[BenR]

its some spacers and longer locking gear due to the vvt pulley being bigger than the non vvt pulleys.
