16v engine ticking

[Slugger]

Just changed the rocker cover gasket and spark plugs on the 16v and now its making kind of a ticking noise which gets faster as you accelerate. I accidently left the two breather pipes off the front first and when I started the engine I could hear what sounded like air being sucked in but it wasnt ticking. So switched off and connected the pipes and then when I started it again it started making this ticking noise.

Any ideas?

Cheers

oil level ok? probs a noisy tappet

 

[Scribbler]

Sounds like tappets!

 

[Mark]

there followers from what i understand no tappets

 

[Mark]

is it a quick tapping, theres no reason y taking off a gasket should cause ticking did u do anything else. u got the right plugs???

 

[Slugger]

But it wasnt doing it before

Just had an oil change a couple of weeks ago, level is still good.

 

[Mark]

are they the same plugs that went in that came out but new. long shoot but could b hitting crown of piston if longer. im guessin now

 

[Slugger]

quite quick and gets quicker when you accelerate

they are ngk uprated spark plugs from k-tec

 

[Mark]

mail k tec mate they might know a bit more about it,

does it run ok in general apart from the noise?

 

[Slugger]

not been out in it just left it running in the garage, idle and revving it seems ok but will take it round the block in the morning

 

[Andy GDI]

did you use a thin oil???

 

[Slugger]

10W40, been runnin fine on it until I just changed the RCG

 

[Paul C]

as far as i know all valvers make a ticky noise but if it didnt before i dont know why it would now? maybe try some different oil? something a bit thicker.

15w 40 stops tickin

 

[Slugger]

Dont tell me that

I wanted 15W 50 but garage couldnt get any, I was told by multiple sources that 10W40 would be ok

 

[BenR]

hmmmmmm.......

If it deffo wasnt making this ticking noise before.........

How loud is the ticking...just about audiable?

Could be the injectors, but try swapping back to your old plugs to see if it goes.

 

[Ben j]

he he he he he

 

[Slugger]

Its not loud loud but it is obvious and easily noticeable from inside or outside the car.

Will try old plugs and see. If it goes what does that mean? Why would the new plugs make this noise?

 

[BenR]

Dunno, something i would have to look into.

 

[Slugger]

ok cheers

 

[JAY172]

have you disturbed a plug lead. eg-broke the rubber insulation causing it to arch to the head or something.

 

[stan*]

[Mark]

did you use Magnatec oil by any chance, if you did that will be the cause, change it to somethin else

its done it to god knows how many people on here

 

[Slugger]

Oh yeah......

Dont know what oil they used but.....

Changed the spark plugs back, still did it. Took the rocker cover back off to see if I could see anything, nope. So, fitted another rocker cover gasket and re-assembled, still did it. Went for a drive round the block a few times to see if it drove ok and it seemed alright. Noise wasnt all that loud from inside the car while driving along but could hear it and was still quite loud from outside at tickover. Later that day dove it down to the shops prob a couple hundred yards away, by the time I got there was thinking hmm cant really hear it now. Let it idle a bit while listening for it and it was gone. Drove back home, no noise. Put car in garage a few hours later, no noise. Been fine ever since.

Most strange.

 

[BenR]

You checked to see if your exhaust is blowing around the cat joins?

This always makes a ticking noise and can be heard inside the car.

if the car was sitting a while whilst you were working on it, they might just have drained a little, run it till warm to see if it goes away, they are louder for a while if engine hasnt been running for a few days, these hoses shouldnt have afected it at all
