Give yourself plenty time - Slow and steady or don't start it!

The job is a nothing job really but if you strip any threads it will become expensive!

The whole design of the cam follower is crap to be honest. Hence VW changing it to a roller follower instead, still not a brilliant design in my eyes.

Right I changed my cam follower today and mine is the early two metal pipes. No issues at all pics of the old one bellow. From what I can see in the history it was the original one and as you can see started to show some ware but not as much as I thought.


When I did the two fuel lines the right one was no issue as we have all the same and know how to do that. The left one I undid the torx bolt from the bottom of the union. There did not appear to be any washers. Removed the bolt and changed the follower and then used the same one. From looking inside the hpfp there is a thread that it went in to and did not appear to have to cut its own. Little trick was to use a separate torx from another set and then slide a small adjustable spanner over it with some tape on the bottom to stop it falling out this making a small socket set up to allow access.
When you look at it the head of the bolt I removed is the round bit at the bottom underneath the joint on the left pipe. Hope that makes sense. Took half hour.

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  :scared:  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!!! :ashamed:

Cheers



Looks very scratched. Was to oil ok?

I am thinking to change my cam follower as well. Can anyone tell me what are the side effects of a failed cam follower? How can i understand that the follower has failed and it needs to be changed?

Cheers

From what I understand if it fails it can write the engine off from secondary damage. For the sake of £25 for the part change it for piece of mind

did this a few months back. Big tip, leave the drivers door closed. i left it open and it primed the in tank pump causing fuel to come out even after the fuse for the HPFP was removed.
the way i did it was to remove the fuse, run the engine till it stalls to remove fuel pressure, and then use the schraeder valve to remove the remaining pressure. The rest is quite simple after that.

I left door closed and parked overnight. Opened bonnet through window and when I undid hpfp had just a dribble of fuel no issues.
