Just a heads up really.....
yesterday afternoon i replaced the timing chain and cam cover gasket on my valver because the chain was noisey. the new chain i fitted was very tight compared to the old one that had about 5-10mm slack :shocked:
Took her for a test drive after i finished, what a foooooking difference it made!!!!!!
smoother tickover, better response from low revs, and after 4000 revs :grin: :grin: :grin:
If you have a valver lads and lasses and that chain is singing a tune, get it changed FTW
Best mod you can do for more horses :cool:
Bloody thing wont start again when warm now thou, i suppose its produced higher compression??
I think i need to service or replace the starter, and clean the -ve strap that goes to the gearbox from the battery when i get a min. I cleaned and greased the starter connections last time i had this problem.
-
Bloody thing won't start again when warm now though, I suppose its produced higher compression??
How on earth did you come to that conclusion?
If this is a problem that has occured since the work then the obvious reason is that your timing is incorrect.
-
After doing rings and head on my golf she doesnt like to start when warm. You can hear its all tight but should loosen up soon enough as I have only done 300 miles in her. I'm not too worried but, should I be?

Inlet valves shutting a bit earlier on compression stroke :huh:. The exhaust valves are on the belt pulley so the only timing adjusted by replacing the chain is on the inlet valves
If this is a problem that has occured since the work then the obvious reason is that your timing is incorrect.
All cam belt timings are spot on, dizzy is in same position that i took it off, but i havent timed it up with a strobe. she flyes thou with no pinking and on reg unleaded not super unleaded (never put super in since ive had it :rolleyes:)
it was struggling to start before i replaced the chain but its just getting worse.
Ive been to the scrappy today and removed a beefier -ve lead off a polo (same length with all connections and twice the thickess wire :grin:)and ive doubled up on the +ve from the starter to the battery.......
still no good when she is hot :cry:.
If i leave her 20 mins she will start but if I stall it Im fooked!
Ive a spare starter somewere i will service and try when i have a min

my mate rebuilt his valve, rings, shells n stuff and slapped some bike carbs on. he brought an £150 battery from halfords to turn his over :laugh:
It should loosen up just make sure it dont overheat before it does, take it easy with the right foot for a bit :wink:

Oh right, so you're just achieving factory compression (minus wear over the years). Pretty sure they started from hot from the factory.

You say it was struggling before you did the cam chain, so leaving everything in the same position won't have helped resolve any issues. Get it set up correctly and double check all the marks, especially the cam marks where the chain is.
You've done what you can with the wiring, so next step would be to check starter motor.
-
Mine was fine before, and I marked up the timing belt before removing it and then marked up the old one accordingly. She is all gravy just a little 'tight' when warm i guess. Cam timing is like so ----> >)(< with the cam pully at tdc

thnk you'll find ignition timeing is out

Beat me to it! :wink:

Who, me or the other guy :huh:
-
Who knows but i can put hand on heart and say the cams and belt are set up correct on mine so it must be my dizzy out or starter tired.
weekend job me thinks, im on call but it should be quiet (bank holiday) :wink:
-
it must be my dizzy out......
Otherwise known as ignition timing :wink:
-
Me or Bodga? My point stands :grin:

What do you mean by tight? slow to crank when trying to start?

Yer slow to crank and then just starts, as if you have worn your battery down trying to start and its on that last almost dead turn of the key :embarassed:

get a heavy duty battery and check your starting and charging circuit also.....
-
But why would it be fine from cold but sh!te when hot? The battery is literally brand new but will get a volt meter on it and test across my alternator.
-
If anything it should be easier to start when hot. The starter motor on the 16v was real slow to crank over, hot or cold. Eventually it packed up, but I stuck a working one on and it cranks perfectly :smiley:

Sounds like something I'd like :cool:

Sam, that just sounds like your starter is shafted

No sh!t :grin:
timing on mine is spot on peeps. :grin:
Ive noticed though that the battery i have fitted is a type 065, (it came with the car when i brought it) but ECP quote a 075 to be fitted to a 16v, can anyone confirm this? what batteries are fitted to your valvers?
Ive aquired a battery off a ford transit (new one) but the terminals are the wrong way round :angry: Leads just not long enough to fit. good to test with jump leads thou :wink:
-
075 or 085 would be better on a 16v, the extra will help with starting etc.
-
i presume it not cranking over very well when hot.
when it's hot disconnect the king lead that goes to the dizzy and cranck it over, if it spins over much better, your ignition timeing is out FACT
it's slightly over advanced you need to loosten the nuts on the dissy and set it up with a timeing light. the ignition timeing is diffrent to the timeing between the cranck and the cams and the inter cam timing, it has it's own adjustment and is rather a lot more sensitive just fitting a new cam belt can throw it off

Get a bigger battery......then set your ignition timing with a light. you'll think you have a different car
