Hi ppl. i got a 1.8 gti 16v which i bought recently. the problem is that its developed a ticking sound, when i rev the engine it ticks faster, sometimes it gets really loud. does anyone know what the problem is? Please help!!!
-
Where abouts is the noise coming from? Cylinder head?
-
near the cam belt or it maybe the cylinder head?
-
went to 2 mechanics. one said that the engine is tired, which is bulls**t because its done 150k on the clock with full service history and the other said something about the power steering.
-
Listen carefully to the ticking sound and try to determin the speed. Is it regular and about half engine speed? If so it could be a hydraulic tappet getting lazy. If it is more like a heavy knocking sound coming from the depths of the engine, then you may have big end bearing issues. Check the oil level, or even give it an oil change to see if that makes a difference.
-
Just a thought... Check the cars history for when a cam belt & tensioner change was last done - Perhaps the tensioner pulley is worn?
:undecided:
-
the power steering belt, fan belt, cam belt tensioner stud, cam belt tensioner and the cam belt were all done back in last december.
-
i'd take a guess at something like cambelt tensioner and cambelt. Check the cambelt isnt hitting the plastic cam cover or the metal sheet on the other side. Im telling you cos i had it before.
-
I'd say thats a tappet failure by all accounts. 150,000 is about the time they start to die. Oil change will definately help this quiet down.
-
Could be a lairy injector, I had to replace one of mine because it got that loud! Speaking of injectors, does anyone know what colour should be on the 1.8 diji? I have a mk3 block and I have yellow... sure this isnt standard??
-
most likely to be a tappet on a 16v, theres twice as meany to start ticking. they normaly go quite once the oils warmed up but they can really make a noise
-
on a digi there were loads of different colour injectors fitted, with slightly different ratings but all interchangible. if you can get me the vag or vw part number off one i can check.
-
I had this problem a month ago. Knocking sound from around front right wheel, had all pulleys checked, which were fine. Turns out it was the water pump. Had a new cambelt fitted whilst everything was off and it's quiet as a mouse.
Apparently the water pump bearings can go and rattle like a bag of bolts. Hope this helps.
-
Apparently there were two sounds, one was coming from the power steering pump and the other was from the water pump pulley. the mecanic changed the power steering pump and the noise is gone quieter but now i just need a pulley and i cant find one anywhere. i rang GSF, they dont do it, rang VW, they discontinued and the rest dont have in stock. went to the scrappies and they just have the 8valve engines, the pulley looked different. Does anyone have a spare one or know where to get one from???
-
if you really have no luck finding em, it might be worth upgrading to the MK3/later Passat/SEAT water/pass pump & alternator setup, bolts right on. Any 8v/16v from 1.8 up will fit, the only issue is you need an ABF crank pulley which is reasonably hard to find unless you spend top dollar for a new one from the likes of BBM in America!
There are 2 types, the early setup where the alt just has a big spring underneath or the late/aircon setup which has a seperate tensioner wheel. Only difference between the 2 is the alternator, belt and the alternator bracket the rest of it is the same.
Well worth it though the tensioning system is miles better:

I know its unlikely but when I had a ticking on my first Golf it turned out to be pulley (dont know the propper name :rolleyes:) that both the PAS and alt belt go on and it cost a b@stard fortune for a new one !
-
yeah its a slipper pulley on some models, if i ever had that id be upgrading, will cost less and you end up with a much better setup!
-
I've got a spare now :wink:

Sounds like a lazy hydro tappet to me....I had luck quietening one down by draining the oil & filling (then running for a few minutes) with flushing oil, harder to find in gallon tins now, mostly iccle cans of add in treatment. Still, even an add in tin of engine flush may do the trick before treating her to fresh oil....carbon deposits can block the oil suply to the tappet causing it to not quite pump up propperly, causing a tick-(top of the engine half engine speed) flush may shift the blockage :smiley: Good luck! Marc.

Thanks :smiley:
