Good afternoon all just wondered if anyone could let me know when the recommended time is for adjusting the Tappets. My engine has done around 50k miles.

Thanks in advance,

Paul

 

[Dirk BT]

every 12k km is recommended.

Cheers
Dirk

Thankyou dirk does the bi turbo use a standard gasket ?

 

[Dirk BT]

[pulsapharer]

Thankyou for the quick reply yes I meant the rocker cover I understand it's 0,25 on the exhaust and inlet with a stone cold engine

 

[Dirk BT]

on the BT I use the original valve clearance with 0,30....as it is the original 535i cam in it no probs so far

 

[pulsapharer]

The engine was totally rebuilt by Alpina 10 years ago so assume that it's got Alpina cam in

 

[Dirk BT]

if you have an original B10 BT then there is an BMW 535i cam in it, check the parts catalog

 

[pulsapharer]

It shows that the part number for the Camshaft is 11 31 1 287 606 and also managed to get some info from Alpina saying that the Exhaust and inlet are 0,25 set on a cold engine.

0.25 on mine and it purrs like a kitten.

here you are Camshaft, 11311287606 ? BMW parts catalog

and if 0,25 or 0,30 ...any noticealbe difference in power output? :biggrin:

Nope, just a noticeable difference in tappety noise at tickover :hihi:

I don´t care, the injectors are as noise as the tappers :grinyes:

I don´t care, the injectors are as noise as the tappers :grinyes:

mine are even louder than the tappets

 

[pulsapharer]

I contacted Alpina and they sent me a spec sheet and it says valve clearance is 0,25mm for both the exhaust and inlet. Is there no way of replacing the injectors with quieter ones?

 

[Tomba]

Can you post that spec sheet?

 

[pulsapharer]

This may sound stupid how do I do that ?

This is a very good document for english users who don't know german. It is a simplyfied document of the original german I believe. Thank you very much for sharing this!
