My gti6 has decided to being annoying, even though much care is given!!I just did an oil and filter change. Used full synthetic oil as usual. Engine suddenly started tapping on idle, but doesn't get louder under load. Also noticed my oil temp is a few degrees higher than normal. Performance is the same! Far out! What is going on? ________________________________________ 1998 GTi6 Bianca White |

Pressure in the head can lead to it coming loose over time if its not properly torqued up - is my guess  ________________________________________ ''Oh, it does handle like a golf!'' Why drive a Golf....when you can drive a GTi-6? |

I had that where a plug came loose. Check it. He's probably right.  ________________________________________ See the sheer power and might of the lesser known burrowing owl. |

You sure its the engine and not the cat or heatshields? ________________________________________ Pug fee`ver,Pick a Bogey, buy a Pug. Black 306 GTI 6 Standard, was 60k mileage, bargain!!

Was definitely the engine. The cat is good and the heatshields are very secure. I checked the plugs they are all good! Strangely the tapping has stopped, turned the car on this morning and it sounds healthy again!! Is this normal haha?? Anything else I should be checking for?________________________________________ 1998 GTi6 Bianca White |

I have noisy tappet. It taps for a bit and goes away, or sometimes it just dont tap at all. If has a tap though, its only on start up and always dissappears in a minute.  ________________________________________ See the sheer power and might of the lesser known burrowing owl. |

Are you sure it isn't just because the new oil hadn't had a chance to circulate?I've noticed that if you start one of these after it has been sitting for a while it is slightly noisy for a few seconds before the oil really gets everywhere. ________________________________________ 61k miles Ph.1 Diablo '6 Project Thread |

Did it tap after you checked the plugs. It's hardly any movement that can make it happen - under a quarter turn. Worth cleaning down the threads anyway. Could also be a tappet but its pretty rare on these.Happens due to the heat cycles on the engine, usually when its got bloody hot or bloody cold. Other cars do it when cracks appear in the head - see Volvo early me7 s**tboxes. ________________________________________ Nothing to see here |

Noisy tappers are rare on 6 engines but they do happen. My old Diablo one had never had belt failure or head removed (you could see how rusty the head gasket was poking through the sides lol) and some days it would be quite noisy and sous almost as loud as a tapper and others be pretty quiet. And these engines are meant for 10/40 or 5/40 in cold climate according to the owners manual so shouldn't be a problem. ________________________________________ Black power baby!

I had a tapping noise on my ex-206 RC (GTI180) back in 2008. Cause was a loose spark plug. Damn it freaked me out back then but was sorted easily  Sound was somewhere around failing tappet and a failed big end bearing.. It was louder than a tappet would do and it didn't change if the engine was cold or hot, but not as loud as a big end bearing would do.. ________________________________________ 306 S16 "Peugeot Sport GrpN" '94, 405 Mi16 "OEM+" '89, 605 SV24 "Executive Express" '91 |
