I just put the engine in KMP625, fired it up, and had no
oil pressure so immediately shut it down. The short history; the engine (Aluminum Shelby block 468) was build by a well known builder and was run on the stand/dyno with correct
oil pressure. The install has the high pressure line from the
oil plate going to the ring of oil filter holes, with the return coming out the center and then going to the cooler, then the lower return on the adapter plate.
Prior to firing the engine was cranked without spark for about 30 sec to prime the lines/filter/cooler. Has anyone run into this? Aside from a bad sender I can't think of what the issue is, and a bad sender seems improbable. Do I need to prime the filter/cooler longer? Even if the filter was plumbed backwards, would it result in no oil pressure? From my reading the filter only adds a few PSI pressure drop, so this doesn't seem likely.
many thanks, Mark
