    ok, well my engine and transmission is finally in the car, after about 3 years

    just want to know what might need to be done to run it in, its a roller cam block out of a VT 5.0, is there a run in procedure for the cams on these?

    anything need to be checked in particular, been reading up on other forums regarding priming the oil pump

    No break in with a Roller Cam, good idea to at least pull the plugs and crank till you see Oil pressure before the first fire up, good luck with it no better time during a build!  :XD:

    I would prime it yes what where you planning on using for that?. Then drop the oil after. Then use proper run in oil as well

    That was pretty much the thought we had, I was worried a bit about turning it over as is with it sitting for the time it has been, was thinking of putting some of the Penrite run in oil I bought  into the tops of the pistons, just in case the assembly lube is long gone

    Sure it’s been answered somewhere, but what’s the best way of priming the oil pump, I did google it but a lot of the suggestions contradict each other

    My mates we packed it with grease and then flushed it soon after. We were having massive issues getting oil into the top end that worked a treat.

    If you spin it on the starter without the plugs in it there will be bugger all load on anything hence wear.  If the oil pump doesn’t self prime like that you have other issues….

    The ideal way to do it is you screw a fitting on the oil pump filter thread and use say an old power steering pump driven with a drill to prime the engine. Turn the engine over by hand while you do this, that will get oil up to the rocker gear as well before you start it. And a bit of vaso or sticky assembly lube on the pump gears to get some suction happening… Trying to get oil pressure off the starter is :negative:

    Air hose into rocker cover. Crank with coil lead off and wait til oil spills out oil pump fitting. Where pressure sensor would be
