[DeTomaso] Mayonnaise on the dipstick

Dave, if ANY noticable amount of water/antifreeze is in the pan, its a 
popped gasket- as you say, probably the head gasket. If your stars are aligned 
and are very lucky, Bars Stop-Leak may seal it up temporarily, but if it 
does, it'll take a few hours (which you probably don't have to spare) and you'll 
be on pins & needles the entire drive anyway.... I'd pull the spark plugs, 
look for one thats rusty on the end and if you find one, change that head 
gasket. If none are rusty, its probably the timing chain cover gasket. 
Note that there are several designs of the steel front plate and one 
unaccountably has a right-angle slot milled around one of the water pump ports. 
The stock gasket blocks this weird slot off, but I've seen aftermarket gaskets 
that don't quite do it. If your front cover has this "feature", plug the 
slot solid with Permatex. Usually, it results in an external leak, but.... 
Good luck- J DeRyke
