I want to run it as it hasn't been started for 12 months and the van is a few weeks from finished paint, I would like to run it before I put it back in the van and discovere there is a problem, I will also hook up the radiator may be more hassle than its worth but just a thought. did a compression test today 150psi in most but 140psi in a couple of cylinders, would the compression be down a bit due to sticky ring??? cheers
