hi all,just wanted to know about something thats getting to me,had the tapping on my 6 so i had the head of only to find out there was no bent valves? but have been told that the guides on the exhaust side have all got too much play in them,so i will replace them all,just wanted to know would this be why it is tapping as i have had all the other possible other signs checked, as in lifters and such valves are all fine,and inlet guides are fine too

cheers mate,but if the exhaust guides have too much play would this cause it to tap? as the valves are ok

The only way to check for very slightly bent valves is to give each valve a light lap, if each valve cleans up all the way round your fine, if your unlucky like me you will find two valves that only clean up half way round that needed chucking in the bin.....
Check my project thread out for further details & pics

Deano, your missing my point, you won't know if any of the valves are bent until you try to lap them!!

As wayne says, lap the valves in lightly, you will soon spot the bent ones!
