Valve springs are becoming more and more an issue especially as age fatigue is becoming apparent.

Ask any tuner and they will tell you they see it even some lower power cars. My FG needed valve spring at just over 310 rwkw. I changed them of coarse.

You would be fooling yourself if you havn't budgeted for them of make an asumption that you dont need them.

Cheers Paul

over time you will end up changing them. Your tuner can tell when he tunes the car if there is any issues or float.

Some people get lucky, some not. My motor only 24,000 old so im all good for now. Will eventually go to atomic v/springs though one day when needed

My 07 BF MK 2 foon ZF has a tune with 360rwkw. Got the hardware and could push 380, but at around that mark the car was getting valve float. I chose not to worry about putting any in and keep it at 360 with 1060nm. It is a sh*tload of power anyway for a daily driver. I've got another tune at 370rw with 1200nm in the box I could load up, and the valve springs seem alright..

My new 316 odd rwkw tune is going well aside from one problem I spotted yesterday, after giving it some stick and stopping at the lights, the car was idling roughly in 1st or 2nd (ZF box), felt like it was about to stall now and then. Simon (tuner) suggested valve springs. My car has almost got 100,000km on it now. It's fine under power.

Due to age of springs I'm guessing this might be the problem? Car is a June 2007 BFII.

I don't know what valve float feels or sounds like though. Can someone give me an example of the symptoms that failing/fatigued springs cause?

Might have to back it off a bit in the meantime :/
