I well and truly bu666ered a stag doing just that. The problem is that all the wear with an egine takes place at start up when cold. Plus you get oil drain in a 4 week period. So effectively you are causing as much wear as you can. In the case of the stag I ran the camshaft bearings in one head.
I'm for nobbling the fuel pump and running up the oil pressure but I would be a bit worried wehter that would throw an EML.
