my 92 turbo automatic constantly over heats, i only have a greddy boost controller that i run at ten psi sometimes otherwise it is a stock jspec engine that i replaced the original with. sometimes i can smell gas while boosting and i think theres a little oil in the water, and a small oil leak, i know pretty weak huh? anyways i recently set my timing back from about 14-15dgs btdc to around 12dgs btdc and white exhaust is now pouring out the tail pipes especially with throttle, of course i tried setting it back but something blew. I think its time i changed the head gasket and was wondering what other mods i should take care of while im in there to make this thing run like a dream at 10 psi all the time, any suggestions or advice about mods or repair ideas would be greatly appreciated thanks.
