Okay, quick question about the top mount... I have obviously chocked the engine mount to get rid of the rocking motion forwards/backwards but by going by the witness mark/clean bit on the chock, how much up/down motion should there be? It had a new OE top mount late last year which is when I fitted the chocks. Edit: Suspension  |

those wear marks do seem to go up-down quite a lot, mine is more like the pattern you can see behind your chock on the actual cradle, extends a lot less far upwards.

hmmm do those 'chocks' make a big difference? I just fitted a new top mount + cradle and still have a lot of play...(resulting in the exhaust hitting the subframe  )________________________________________ Team WheelwhoreTeam Limited Edition Astor 306 Francorchamps RIP Virtual Blue 208 GTi quote: I  this place.

When I got my tyres replaced, I said to the guy in the garage that I might want my engine mount cradle welding. He then went to get a 4ft BFO pry bar and levered the engine up and down in the mount, and said the mount was meant to do that. I'm not convinced and as I'm away from my tools, and facilities, I just wonder whether the mount has the capacity to move up/down...or is it just taking the threaded portion of the cradle up and down with it? I'm guessing it is the latter, as the witness mark BEHIND the chock would be significantly larger? Discuss.../ |

Part of that up/down will be from the mount rocking rather than just bouncing up and down though, but can you not alter the upper buffer on the '6 by unwinding it?You can on my 405, although it has a more progressive upper buffer. ________________________________________ - Bespoke rollcages/additions/adjustments.

only the lower one (but got a new one ready to replace it)the one on the gearbox-side if fine I did notice some 'play'(could wobble it around a fair bit, dunno if that's normal) when I put the top mount in place but the cradle seems fine (no cracks or anything)  sorry for hijacking your thread  ________________________________________ Team WheelwhoreTeam Limited Edition Astor 306 Francorchamps RIP Virtual Blue 208 GTi quote: I this place.

Well obviously once it has the weight of the engine on, it won't move round so much...The chocks are a good idea, I did do a whole load of them but now am all out. They aren't that hard to do, its just a bit of messing round you have to do. I'll get a pic and edit it into this post...  |

About 3mm, yep. They were the first set I did which were slightly too thick I think. All the rest were 1/8" if I remember rightly |

Won't the thickness of the chocks allow the engine to move up and down by 3mm more than before?________________________________________ S Reg Diablo standardsSpec SORNEDR Reg Nile standard spec written off then repaired X Reg Astor in need of TLC R Reg Nile to restore Set of Lions to fit. |

I've got some possible outcomes I think...1. Mount cradle is needing to be welded, its gone like all the rest. 2. The other mounts are shagged and engine is flopping about like ratty on the nest 3. The squeezing effect of the chocks is forcing the mount upwards (like if you squeeze a bar of soap out of your hands). |

You could make some chocks for it out of angle iron, I'll do you a drawing of some if you would like________________________________________ andrew315rawson@live.co.ukMoonstone phase 7 gti6 My Project thread: http://www.306gti6.com/forum/showthread.php?id=119992&page=1 |

Do you squeeze when you bend over for the soap after it goes flying out of your hand from squeezing it, it hits the floor and ends up dented?________________________________________ andrew315rawson@live.co.ukMoonstone phase 7 gti6 My Project thread: http://www.306gti6.com/forum/showthread.php?id=119992&page=1 |
