Gary, The pump is a 'Shurflo' distributed by Westech (512-847-8918) used by NASCAR for circulating rear-end lube,..among other tough jobs. The problem of oiling at idle is mostly because the dynamic oil seals in the turbo require a certain rotation speed of the shaft to be effective ,...and depending on turbine A/R it could be spinning too slow. I think the 'stagger-gap' sealing rings sold by Turboentics help considerably. Jeff Churchill J.C.
