Just curious about how everyone treats gaskets. I'm in the middle of a Ford diesel (with a jap engine, PUKE) rebuild and the gasket kit for this thing, from the dealer is over $400.00.Im trying to get away with just buying the majors like head and oil pan, etc., and making the rest. On head gaskets I use Permatex Hi Tack spray and on oil and water gaskets, hi temp silicone, don't use anything on cork unless it's a oil pan gasket. Cork oil pan gaskets get silicone and get tightened over a period of time as it sets to avoid "squish out". Cork valve coverg go on dry. I might use a light coat of Hi Tack on those thin oil pump cover gaskets after they've been resurfaced, just to make sure it's sealed. Nothing but oil on NPT fittings. I put very few gaskets on dry anymore, just can't seem to stand even a hint of a drop or seepage on a new engine given the time that went into it. I've never tried the lacquer sealer as I've taken a few apart with it and didn't like how it crystalizes and cracks. The only reason I ask this question is I'm wondering what the latest gasket technology is. Just about every gasket on this engine rebuild appears to have gone on dry, but is D--- tough to get off. I know that head and exaust manifold gaskets sometimes come coated with a heat activated substance that seals up when it reaches operating temperature. On metal head gaskets, I definitly use Hi Tack. On these coated, temp activated, head gaskets, I don't know anymore. On this C-123 engine I just finished, one side said sealer and re-torue required. Is that just sealer on the one side? The other side said nothing, I sprayed both sides with Hi Tack JIC. I'm wondering if the gaskets on this Ford, although they look like plain old gasket paper material to me, might be impregnated with something I don't know about? Any Comments? Thanks, scott#2
