You're on - and then when you think it's "done" I'll check it against my SP timing kit, and show you how many degrees out you are, on either the cams or the tension ;)

Your car - I think not!

Quoteif you built up an engine that had broken its belts you aligne the cam marks and insert the tools, what i do is aligne the marks and clamp the cam shafts wheels, it does the same job , ie locks the shafts with the timing marks, it may scare some folks but it can be done,  just trying to help the guy,  but yes if you can get the tool beg steal or borrow it use it

You will never be sure the V6 timing is spot on without the locking kit.

I agree, pretty much any other engine you can just lock the cams and if the marks line up you're good - but NOT on the GM V6. The timing on these engines is fractionally adjustable with the idlers, and you CANNOT get this right without the kit. Trust me ;)


Not done a GM V6 but surely it's just like any other modern engine?
As long as ALL the timing marks are alined and the belt tension is set right (ie to ensure no slip but not too tight to cause premature failure of bearings or belt). :question

The idlers are there to do just that IDLE ie nothing but help the belt change direction between the banks and crank?

Agreed this will be difficult to do without the locking kit as you need to get all 4 cams and the crank aligned at once - but not impossible (molegrips though??) :)

I'm sure i will be corrected so standing waiting :-?

Quoteyou dont need a locking kit, when you have all your timming marks inline clamp the cam shafts together with mole grips, fit you belt anticlock wise a be very carefull, if it helps use a tipex white pen to highlight the timming marks first,

Timing is micro-adjustable through idlers......

the idler pulleys adjust the cam timing bud not just a case of lock it up and fit !! can make a massive difference to performance of engine !! any muppet who uses molegrips is asking for lots of trouble  >:( >:(

sorry don't understand how? i'm used to one fixed postion of timing if you get it out by a tooth it will run like a bag of nails, if timing a performance cam you fit vernier sprockets for finite adjustment but what do the idlers do :-?

and i will be corrected but that's why i'm here to learn :y

Yep, the position of the idlers affects the valve timing on the V6

I'll show you sometime :y

get the cambelt dvd bud it shows you there !! basically you have to adjust the banks to be in time with each other !! when i did mine watched the dvd 4 times before i got it propley and im a mechanic !! ;D

this just gets better, explain how a fixed belt tentioner thats has been tentioned corectly can adjust the vave timing, dont forget the new belts has the timming marks on it, the tentioner just becomes a belt guide once its set ? but please tell this muppet more

there is only 1 tensioner then there are two idler pulleys which are on concentric centres therefore enabling you to adjust the cam timing !! the tensioner adjusts only the tension of the belt ! if only it were that easy bud !! :y you have to time 1+2 banks firist then 3+4 banks then turn round and check and then adjust again if needed !! :y

correct full points to you, time up the engine,AND LOCK WITH MOLE GRIP , remove old belt etc, fit full new belt kit, tentioners and ideler pulleys, start at crank with belt mark to crank mark ,fit in a anticlock wise direction, twin lines on belt will aligne with cam marks,when its all on ,adjust right tention anticlock wise, making sure nothing moves, then do same to left tentioner anticlockwise, recheck nothings moved, REMOVE THE MOLE GRIPS, turn engine 2 turns, all belt marks will be out of agline now,adjust again in the same order but tention clock wise this time, recheck nothings moved,set final tention 2,3 mm job done , put back  together ,THEN GO TO PUB
