show me your pumps...and 1.6 mechanical valve clearance. by carrizog60 on 23 Nov, 2008 14:26

on the belt side of the pump there is a small arrow,can you show me one of a pump that is timed to 1.00/1.05?
asking because my pump looks to be advanced too much but the dial just shows 1.05.
timed now to 0.95 and it seems the engine got more silent but only tomorrow on cold start will check that.
"line and 0" mark on fly match lobes of cam in the closed valve position,pump is also with is marked aligned so no missed timing.
just for piece of mind... :roll:
also, what are the specs on valve in the 1.6 mechanical head?
being a n/a that got turbo conversion would the valve adjustment be different that as for n/a? -

exactly the same problem... but i have an hydro head ... JR engine...
(desculpa tar a falar em inglês, mas como o fórum é todo em inglês, é so para eles entrerem na conversa.)
dont have a timming gauge, not shure if the rattle is normal at cold start.
when warm sounds like a clock... :?

Here is the specs from the Bently book. If you find the gaps are off you will need a selection of shims to exchange with the existing shims in the head to get the gap correct. Not an easy job, especially without the special tools.
Good Luck.

Reducing piston thrust from 1.05 to .95 WILL reduce noise. Too far and wont idle smoothly. Economy may go down too -

economy is very good,over 1000km a tank. -

So you've done 1000km since backing off the pump timing? Or are your economic mpg results for pre change? It may be you are already at the optimum setting for economy, and willl have to accept the noise. //isn't an n/a slightly noisier than a TD? Exhaust wise at least... :? -

that was before i backed the timing.
dont know if is noisier in standart but now is a turbo diesel with all gtd stuff.
could be also bad valve adjustment?
