Does anyone know if the exhaust manifold stud holes in the 1G 6bolt turbo cylinder heads are blind or do they go all the way through into the head? I will investigate myself with a thin poker in a day or so. I only ask because it seems as if oil is leaking past my exhaust manifold studs. This has actually happened on a previous car of mine, and the only solution was *gasp* high temp RTV on the threads... which is kinda stupid considering hydraulic locking or whatever it's called. Any one have any similar issues?
