Unfortunately that does sound very much like a 'tapper' which is usually a bent valve or guide that has been left in there after a belt failure. Because yours is tapping all the time I'd go with this.I bought a '6 not so long ago that sounded like a bag of spanners as it had cheap s**t oil in it so I flushed it out and put some decent stuff in there and it sounded lovely. The clue on that car was it was only doing it when warm though but could be worth a try. Other thing to eliminate are loose spark plugs as they can cause a nasty sounding tap. ________________________________________ Ryan |

I can't view the view the video on my iPhone but I wouldn't worry just yet.Is it a tick or a tap? Go through some YouTube videos of actual tappers and you'll soon get the jist. ________________________________________  |

Ideally you'd want to fully recon the head as you can end up with damaged guides and seats as well. Might be easier to just replace the head complete if you can get hold of a known good one. ________________________________________ Ph1 306 GTi 6 | RX8 231 S1 | YBR 125 Cafe Racer | MT-03 660 |

if you can do most of the work yourself you will save a lot, damaged seats and valve guides are rare, just replace whichever valve is bent and have the seats checked/cut.________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

Exactly this, and it's not that hard to do at all.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone  |

I'd also speak to Colin at Pug Performance in Alton Hampshire. He's got quite a few sitting around!! ________________________________________ Richies Project RallyeElectrical work carried out in Portsmouth jamiek_uk2000 wrote: - Top Tip!!!

Thanks guys,Think I will rip it off and have it checked over by a local guy who does cylinder heads. Cost of valves I read somewhere was around £140 for a full set, should be quite a cheap ish fix after all that. J |

Oh, the other thing I need to ask, would the car be down on power due to this tapping? |

The valves are only 'ever so slighly bent' meaning that the force of the valve springs do ensure they get fully shut. However, the "tap" you hear is the valve shutting and "slapping" against the valve seat as it's forced back into place where it doesn't want to go. The issue with this is, at some point, the head snaps off the valve and then you've got a knackered engine. There appears to be no correlation with how many miles or how hard the engine is used to when the head will snap off the bent valve. Some people have managed 30 miles, some have managed 30,000 miles. But be assured, that at *some* point the valve will fail. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

Perhaps they shut 99.99% closed but if they are bent, even only slightly there will be a gap, even a very tiny one? Afterall it's metal on Metal with 'no give'. So if It's bent it will not seat properly. Interesting that no loss of compression is shown if you do a test on any cylinders. |

The strength of the valve spring is enough to bend the valve shut again, so you don't lose compression. When the valve opens it will return to it's bent shape, when it closes it bends back into the correct shape. Eventually the valve will suffer a fatigue failure and the head of it will drop off and your engine will eat it's own arsehole. ________________________________________ Ph1 306 GTi 6 | RX8 231 S1 | YBR 125 Cafe Racer | MT-03 660 |
