timing out

 

[Dan519]

if it's down on power, the timing has definitely been set wrong. There is a sticky thread at the top of this section about why you should always use someone experienced with these engines. Have a good read. If your man thinks it could be a "tooth" out then he hasn't understood how the timing on an F4R is done

the arguement of "everyone has to start somewhere" has one answer, being taught how to do it by someone experienced.

 

[Stephen16vGSi]

this maybe true... timing is getting redone tomorrow.

 

[Martin_172]

by the same guy? make sure he understand the proceadure or else you will be out once again

 

[mark123]

Did you see the borrowed tools? Getting it a "tooth out" is not really possible with the tools. Only without them...

I'd give him a copy of the manual, I can send it you if you PM me your e-mail address.

My old car was 40bhp down on standard after a cambelt change, it can make a huge difference. I really can belive people can get these so wrong. they are not mind bendingly difficult if you done cambelts on cars built within the last 15 years.

If you mechanic only works on old CVH escorts and Cavalier 8valves then your in trouble

its advice am after, ... but whew, aint i wrong.. childish remarks...

Not at all, you've had good advice in both threads, the advice is most mechanics don't do a proper job when faced with a tricky job that is the F4R. There's no miracle answer, your mechanic just needs to do the job right, if he can't do the job right then take it to a mechanic that knows what he's doing. He has got the timing wrong because he doesn't know the correct procedure.

 

[Stephen16vGSi]

car is sorted.. timing was out

 

[jon_r]

Were the cams 180 degrees out?

 

[Stephen16vGSi]

had the wrong locking pin

 

[Dan519]

lol

I think he's more likely put the locking pin in the wrong hole. There's often a balancing drilling quite close to the hole for the lock pin. Fixed loads that have been done that way

Might as well update this for anyone discovering this thread in the future... his engine went boom 3 days later http://www.cliosport.net/forum/showthread.php?602028-i-feel-sick-(-cambelt-snapped.. !
