oh god..

found huge pool of oil under the van..it was a steady trickle coming from the rear of the engine, not dripping down from the oil strainer, but appears to be dripping down tghe fins from higher up, but obscured by the engine rear mounting bar.
Oil pump? Pressure relief valve or oil seal? The van has had a few problems in tghe past with the base of the oil filler neck...
aggh any helpful ideas?
Thanks
