DONE CAM BELT CHANGE - NOW IT RUNS RUBBISH!
« on: 08 May 2011, 21:29:20 »
I have just completed a cam belt water pump and auxillary belt change on my lovely V6  and now it runs like a piece of farm machinery!

I changed the plugs whilst i had easier access and when I discovered the problem I put the old ones back in but this hasn't cured it.

I am motoring on a budget and am scared to take the car out at all like this. Can anyone please offer any advice?

Either timing is out or you`ve not re-connected a plug somewhere. Any codes on the pedal trick :question

Possibilities are:
Air leak
Dis pack plugged in wrong (if disturbed)
Timing out
Something unplugged
Is the eml on?

Pretty sure i have re connected all the plugs - how would the timing be out? I know i didnt use the locking kit, but was advised by other mechanics you didn't need the proper kit? Wold it really send it this bad?

What's the pedal trick?

Unfortunately you've been given bad advice :( To get the timing spot on you must use the correct Locking/Timing tools.

If you haven't got the timing spot on how it used to be, which is probably what has happened, it will run rough

Because you need a locking kit to do it properly.

Oh break :o


You do need a timing kit, it simply cannot be done without it.  Don't listen to any retard who says it can

you've pretty much answered your own question.  ::)
Put another way, if you didn't use a locking kit, can you be sure the timing is correct?  :-/

At best, you may just need to retime it using proper kit, and reset tensioner (you did change the tensioner and the idler pulleys?).

At worse, you may have some bent valves  :'(

have I done any damage? I should have used the correct locking kit I know now- but for £65 for something i would use once seemed a lot of money to just leave on a shelf once used . Just had a new born and the cam kit and pump just cost me enough!

It can be done, just not very accurately, and it's not easy to see the mark on the crank.  ;)

We don't know how far out your timing is. I doubt your pistons have met the valves .............. but who knows.  :-/ :-/
