Failed Balance Chain Tensioner

[Dave Gilbert]

well my flexi is looking abit tatty so im open to ideas.

 

[chill]

Your cat will be further down pipe I would of thought

 

[Dave Gilbert]

its a manicat. manifold with cat in it.

then i have a flexi to straight through pipe to a small powerflow back box..

 

[dewismotorsport]

I have a standard z22se cat lying around from when I took it off mine, so if you do go Astra manifold and adaptor pipe that could be welded in to keep it mot friendly. Only want scrap value for it

 

[Dave Gilbert]

cheers, i will keep that in mind, im not even 100% sure what the crack is yet, i will get the heat shield off in the morning hopefully.
thanks alot for trying to help me out.

 

[Dave Gilbert]

Got heat shield off and to be honest its hard to see down the bottom. I had to take photos but cant see any cracks.

[Dave Gilbert]

it looks all good to me.

i think the dark patches are just shadow

 

[chill]

I think the weak point is where all the collectors meet on top

Like this

Is it cold ?
If so the crack will be more obvious
When it is cold start up and see if you can here clicking,
If not looks like it's not manifold

 

[Dave Gilbert]

No nothing like that. My cats right there so looks different and probably there fix for it.

Looks like im going inside. When the weather lets me.

 

[chill]

It could be the cat has come lose

Ive got the exact same noise ...and i mean exact same rattely ticking pattern as yours coming from my vx220, It happens when cold an disappears when the engine gets to 90º. Evocarlos did my chains last year (big respect for the undertaking) so I'm puzzled as to what this is. I've got a local garage on the case this afternoon Investigating. Will report back.

 

[Dave Gilbert]

Its all your fault then @evocarlos hahahha.

He did my chains aswell. Did you have fai chains ?

 

[Dave Gilbert]

You will have to let me know what the garage says. As I really dont want to take the side casing off, I keep making excuses not to.

But today was a good excuse. I took my girlfriend to do her theory test (which she past). So I dont mind leaving it for another day hahaha.

i got septicemia from your vx220 lol had something stab me in the finger and it went bad lol
would be good to know whats found as it may also help dave

it was gm chains
if its to do with the chains it will be tensioner related i can't see how it could be anything else not in such a short time

 

[Dave Gilbert]

Could I pull the tensioner out the back and have a look? I thought if it was the same kits it would be the same fault hmmmmmm

I dont blame you carl really, only messing hahahha. With all the chains being new I would say it must be something that the chains run, like the water pump or oil pump? Not sure soooooo. I think hopefully see what this garage finds on the vx220. Or I investigate tomorow.

you could but the engine would have to be in tdc before hand so it dont jump not sure what you would gain from removing it other than stripping it down and cleaning it out then refitting

 

[Dave Gilbert]

It shouldt be dirty really then. Oil was new just a week or so before you fitted the new chains then I did the oil again last week. It has been serviced regularly before I got it and every 3000/4000 miles since iv owned it. So like you say no real point. So in that same thinking is there any point taking the side off. I dont know now. Anyone wanna buy a scrap vectra c. Hahah

Any news from the garage??

 

[evocarlos]

only one thing i spotted from your pics
the stud at the chain end of the manifold is new its shiny the rest are rusty

i think you need to remove the cover and see whats going on
