Checking Valve Timing on Zetec
Hi,
I am working through reasosn why mt car wont start and have now arrived at valve timing.
I took the cam belt off to renew the water pump and maybe I nudged the cams along a nitch or two. which would explain the backfing etc.
How can I check the valve timing I have the engine at TDC noe but cant see any marks on the cam pulleys - do I have to take the engine aprt to test
this?
Any help or advice would be gratefully recieved.
Thanks
Frank

I did a similar thing on my blacktop. To ensure timing was right I undid the bolts on the camshaft drive pulleys, then slid a 5mm bar into the other
end of the camshafts - this ensures they're TDC. I then put a steel rod down into #1 cylinder to align TDC on that cylinder (making sure to
account for the small amount of "play" as the crank shaft goes over TDC). Then put the cam belt back and tighten the pulley drive bolts.
All seemed to fire up fine.

You need a couple of special tools, one to lock the crank in the correct position, the other for the cams.
Now I just happen to have sold my Zetec engined car, won't be doing another and have the tools.
£12 inc post and they are yours.
Silver or blacktop? I've a haynes blackie manual for a focus, make me an offer if you want it, and a pdf for silvers I can email you.

take the cam cover off, in the back of both cams is a slot, if you line up both slots and lock them together with a bar then the cams are set right,
there is also a hole at the rear of the block to take a tdc pin, to be honest i would by the kit its cheap as chips and means you are gauranteed to
get it right,

this kit will do both silver and blacktop zetecs

you don't need any special tools, just a 5mm thick piece of steel

but the tdc locking pin makes it more accurate, i know this is locost but £13 delivered for the right tool for the job in my opinion is worth it when
it comes to things like valve timing

No tools for me. theres a mark on the crank pulley which lines up with a mark on the block for tdc. The metal strip/long spanner in the camshafts.

Ifyou've had the crank nut undone you need the locking pin to set it as the timing pulley isn't keyed to the crank. Otherwise you can do
it with just a bar at the rear of the cams.

Yes the pulley is keyed with a woodruff key and no you don't need to lock the crank off just the cams as stated above.

^^ its the Zetec SE's (1.25, 1.4, 1.6 & 1.7) that don't have the bottom pulley keyed
the E's (1.8 & 2.0) all have a key

DO NOT use the cam timing bar to lock the cams so that the pulley bolts can be undone , YOU WILL break the cams. Make up a tool to fit into the cam
pulley holes to use when undoing /tightening. As said you don't really need the crank timing tool if you use the correct mark on the pulley

True. I've just got the SE on my mind having done 3 in the last 2 weeks.
