Hi, I am looking for some advice.

I have just refitted the cylinder head after a blown head gasket and i am getting a clicking/ tapping sound coming from the inlet valve camshaft when I increase the revs to over 2000 to 3000. However when I disconnected the variator solenoid the noise stops. But soon as I reconnect its back again!

When the engine is idling there is no noise. and no noise on start up.

Is this a problem with the variator or the timing?

The car is an 2001 156 1.8

I appreciate your advice

Thanks

Mark

It can take a while to refill the oil in the hydraulic valves have you driven it or just run it ?
Variator I think is more of a noise at start and idle was it ok before ?
Did you use a TDC gauge and proper cam locks when you put it back together

Hi,

I haven't driven the car I have just run it.
There was no noise before the new head gasket.
I did use a TDC gauge and cam locks

Only thing I can suggest is to recheck the timming make sure the tensioner is still pointing to the hole mark on the fixing plate . Check the belt is still tight across the two cam wheels
I know however that when I first started mine after changing the engine it sounded like a bag of spanners till the oil had circulated properly probably 15/20 mins of running.then got better after each start after but worth checking it to avoid doing any damage.

One other thing did you remove the variator solonoid control thing on the head as I cleaned mine inside it can get a bit glupy and sort of blocks the valve hole in the bottom could be causing poor oil feed if its got mayonnaise in it.

Hi,

I re checked the timing and It was out by 1 to 2 teeth on both camshafts. I've put this right now so hopefully once every thing is back together I shall see. I'll keep you updated.

Thanks for all you good advice.

oh dear - the sound you were hearing before was the valves hitting the pistons when the variator advances the inlet valve opening. Lets hope nothing is bent.

All is well. Started up and ran with no problems. In hindsight I should have rechecked with the cam locks after rotating the crank with the belt fitted to make sure that everything was still aligned. :)

lesson learned.
