Think I might have leaky injector seals?

[wisejason]

Can someone please tell me if this is the case or normal. I've attached a photo of the worst one (cylinder 3), but the others are very minor compared to this one.

 

[wayne lcr]

yea its on its way out change them all it ant dear gsf or try the stealers

 

[wisejason]

cheers mate... do you know if this is an easy job? Do I have to remove the fuel rail or can id be done in situ?

thanks lee... now I just need to find out if you have to take the manifold off or you can do with/wihtout removing the fuel rail.

2 Allen botls on fuel rail and it pulls out, not rocket science lol, just clean round them before u remove them, if your only doing lower seals no need to remove fuel pipes, if your doing all seals, best leaving it overnight, then simply take 2 fuel hoses off, 2 allen bolts pull it off and take the clips off the fuel rail - injector. Id say its just as easy as a spark plug change.

 

[wisejason]

thanks Shaunyboy. I was getting stressed earlier when attempting to fix the oil breather pipe on the rocker cover and another part broke off. I bet when I look again in the morning with a clear head it will be as easy as you say.

 

[Shaunyboy]

It will be a doddle after a sleep.

You got to think at the end of the day its nuts and bolts, even an engine rebuild, its how you look at it, if you look at it logically its easy, not matter if you have worked on fords or skodas, knowledge is adaptable

Just look at the fuel rail, you will see 2 allen bolts, thats all that holds it down, just use 2 hands one at each end and give it a firm pull and out it comes, but use some brake cleaner round the debris as we dont want this in the inlet, or even a hoover to suck the crap up . Make sure its all nice and clean and lubricate the seals with a little engine oil so there not dry, dont go overboard just wet the end of your finger and thumb with oil and just make sure there moist.

excellent info mate... I take I can just screw them hand tight? I have got a torque wrench that goes quite low, 7nm I think.

Do you know if they are a GSF part or dealer only? VW just round the corner?

 

[Shaunyboy]

Yeh just hand tight is suffiencent, tight plus half turn id say, there not likely to jump out lol so torque isnt important as it would be on some bolts.

 

[Shaunyboy]

Dealers maybe dear, Try VW TPS.

When you ring just state your a retail customer, and handy if you have the part numbers.

 

[wisejason]

I'll re-read the thread link Lee69 posted. That adds upto around £5 per injector. I'll PM and ask if it was dealer or GSF.

 

[Shaunyboy]

Was pennys last time i priced some up, £1 each i think.

 

[adam cupra 20vt]

There about £2.50 each from TPS I bought some last month but haven't go round to fitting them yet.

 

[wayne lcr]

would you lose power with leakey injecs then does any 1 no

 

[Shaunyboy]

If there bad enough yea as its not airtight, probably not a major loss but not good.

 

[wayne lcr]

so with how bad his is would he

 

[LCRglen]

i have this prob too . am wondering how much it would affect the running of my car and could this be the cause of my long running problem

 

[Willie]

I had all 4 leaking for 2 years plus with no running issues so would doubt it

 

[wisejason]

I've got a major oil breather pipe (PVC) issue at the moment so I would not be able to give an opinion on weather it has a negative effect. Its been like it for some time I think from looking at the picture.

I was more worried about it splitting - not good with a hot engine and petrol vapor.
