There is nothing wrong at all with the whole system. Far be it from me to ever be critical of Lamborghini.
Perhaps you did not receive my communication as I intended. Or I expressed myself poorly.
My point solely is that if a Diablo owner wants to cure the carter motor issues permanently look into ways to remove the carter motor and have another system look after the job the carter motor does. The system can piggy back the original system and there may be no need to do any more.
In addition with the cost and availability concerns of original parts within the system there are alternatives that could be considered as logical but sympathetic upgrades to keep the cars reliable and ensure they are kept on the road in years to come.
