dont quote me on this.. but i heard that if you flush your high mileage or old engine that it might cause some leaks to occur.. deposits from oil burn off, dirt, etc can cause a build up around bad/cracked seals and gaskets, which clogs the gaps preventing leaks.. so if you clean your engine up, you'd be unclogging these build ups and then leaks may occur. but, i dont know for sure.. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/hehe.gif" border="0" valign="absmiddle" alt=':hehe:'> <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt='
