Suddenly developed an engine oil leak and thinking towards Oil Cooler Seals which in itself is relatively simple to D.I.Y. BUT an access nightmare. Anyone had this done at Indy? Looking at approximate Indy charges. If I go down the D.I.Y. trail, there's some great posts on You Tube but I'd be looking for some help / advice as to what seals and extra gaskets I'd require in addition to the obvious inlet gaskets and turbo gaskets. T.I.A.
