Pulled head and the gasket is pooped. Little bit of compression leakage. Pistons are sure clean with the better injectors. Stiil seams imposible to me that oil could get out the passenger side without coolant or oil issues. Oh well shes purring again. Any Ideas as to why the gasket blew in short order. I'm suspecting the water meth. I forgot to mention that the timming was advanced a bit as well wich water meth apparently does not like. I have an AEM kit and was running 2 of the 550 cc tips. I swapped to one 550cc and one 315cc tips. I might pull it back to just the one tip. I did not notice a huge improvement with the water injection as far as power or egt's. It cleans the burn abit. I run the injection all the time and have it set to come in at 10 psi of boost. You go throuh the stuff pretty quick when towing. I'm hoping the new injectors will lower my egt's a bit.

I would have to look at the # on the nozzles I took out. When I was towing a trailer and the min. boost was 17 lbs. all day long it ratio's out to 30 gal. of fuel, to 5 gal. of water. But I live in very mountianest country also.

I would estimate my usage at double that with the 550 cc nozzles. I would go through 5 gallons in about 250 miles. Verry steep hills around here though.
