Title: TFSI cam follower
Post by: GtiKris on November 19, 2016, 12:43:49 pm: Hi people

Today was the day, when after weeks I have finally decided to change cam follower on my 07 Tornado.

Glad I did change it as it was badly worn... not sure how long would it last.

Must say it is a very easy job, took me 30 mins! Very pleased

Mind that's not the normal wear pattern I've noticed either but it looks like you've caught it in time. :happy2:

Did you look at the cam-lobe for damage and scoring? It implies to me a bit of debris has been between the tappet and lobe causing that style of damage.

+1.
I'm no expert, but that wear pattern is unusual, as i think you will find if you have a dig about on here.
As Doyle says, I think it might be worth having a look at the lobe. Easy-peasy now you're experienced!

Post by: 1.8T Chap on November 19, 2016, 08:18:01 pm: Did you prime your pump before starting? I.e turn the key a few times before starting or just started straight away after replacing?
Title: Re: TFSI cam follower
Post by: GtiKris on November 19, 2016, 08:21:00 pm: Opened drivers door, as this prime pump and then turned key few times as well. Car started normally, no chokes etc

The follower should rotate as it runs on the cam, the cam profile isn't flat so it causes the follower to rotate. The wear pattern should be circular on the follower. Something wrong with yours, either the cam is damaged or the follower couldn't rotate for some reason. Very odd
