Porsche Leeds... are they lying to me!?

[max996tt]

Hi all wanted some help please...... i just had a coolant leak on my porsche 996tt out of the blue! basically what has happened is the coolant vent pipe has been rubbing on the intake manifold distributor and has caused the coolant vent pipe to leak. i recently had an oil leak and porsche leeds repaired the vehicle under warranty, what i want to know is do they remove any of the parts.... (1) intake manifold distributor ? or (2) Coolant vent line? because they are saying they didnt even touch these parts or go near em when they reapred my oil leak? is that possible to find a oil leak which took them 2 weeks to intailly find and not to have touched these parts? i was told that they would of had to move the intake manifold distributor when removing the engine? can someone PLEASE help as they are denying this.....and now i am going to issue legal proceedings against them. so just want to be sure. Thanks
