Using aftermarket cams on a VCT Duratec head requires that the VCT valve is removed. Unfortunately this opens up an oil passage which must be blanked, and doing so without eliminating the oil supply to the no 1 cam journal.
This is also known as "VCT Delete", and hardware for this can be bought from massivespeedsystem.com in the USA.But importing stuff from the USA is not very cheap after adding postage, VAT and customs, so here is a sketch for a DIY solution.
I went to a local mechanic in the neighbourhood and got this part manufactured in aluminium.
Glued it in place using Loctite for cylindrical bonding. It won't take any load, in fact the oil pressure will generate forces in both directions and keep it in place by itself. But just to be sure, I made a punch mark that definitely will keep it in place.
