Cam Follower Replacement - Pressure Release Banjo Bolt

[Gide76]

Evening all,

I intend to replace my cam follower tomorrow now I have the m8 spline bit.

Have looked on here and around the net but cannot see specifically how to release the HPFP pressure with the banjo bolt setup.

There is some guidance about removing fuse and running engine until splutter but some say this is not necessary. I can't see an alternative method.

Has anyone done this or know how to release the pressure?

Thanks

Gideon

I assumed that once the pressure is relieved from valve you just remove the banjo bolt.

Perhaps I am over thinking it.

There are 2x metal pipes one with the banjo bolt and one attached to the file line. 

If the fuel line one releases the pressure then that's fine.

Don't have the schrader valve like the newer pumps.

I can't see a problem if you follow this guide

I assume you've got some  mechanical knowledge and tools so then it's just time so don't hurry and you'll sort it!

Thanks

That guide is great but has the schrader valve to release the pressure whereas mine doesn't.

Not any harder - just be careful when first starting the thread off when refitting the pipes!

Finally, a cold engine is a must for safety reasons!

Cheers, plan to do it tomorrow morning after car sat overnight. Will be stone cold and will not be opening the drivers door!

Will take care with the thread.

Right well that was not too bad at all.

Leaving the car overnight and not opening the drivers door meant there was only a very very small dribble of fuel and minimal pressure. Put a tea towel underneath to capture fuel and bolts which worked well!

Bodged taped 8m spline tool did the job and it took around 20mins.

As it happens the cam follower/cam looked ok but as I didn't know when it had been done at least I have peace if mind now.

Mine is the same system as yours - without the schrader valve.
I just undid the bolt slowly until I heard it hissing.
I didn't remove the fuse or set the cam timing like it says on some guides and never had any problems.

Make sure you have an old towel to mop up the fuel though!
Also don't open the door as it primes the fuel pump.

Just read that you've already done it

No worries thanks for response. Struggled to find many specific banjo bolt cam follower threads so hopefully this will help someone else.

Hi gang

I've just changed my cam follower tonight and I have banjo bolt but pressure relief valve too.

It took about 40 mins and I found it an ok job. I did break to retaining clasp off the left hand cable connector on the pump so I had to bodge it in place with a self tapper for now    I will order a new one.

See pics below for wear, Im presuming its the original on a 55 plate with 66k, blufin stage 1. Not too bad, but the hardened coating has worn so I'm presuming I changed it at the right time?!









Bodgetastic!!!

Cheers

[Gide76]

Yeah that connector is a pain in the arse! I struggled with that too and could do with a new one.

Mine was like this car had 89k and is standard. Not one done in the history so presume it is the first change.........

That's significant wear. It's a good job you changed this when you did... once the hardened layer is worn through I'm guessing it doesn't take long to fail (there's a reason it there). I'm at the stage now when I check it every year and replace as necessary. Crazy that most garages still don't seem to recognise this issue.

Am going to do mine tonight. Mine is the early one with 2 metal pipes. I have read something about replacing a banjo bolt and housing as well. Is this right or do you just go carefully
