<HTML><FONT FACE=arial,helvetica><FONT COLOR="#8000ff" SIZE=2 FAMILY="SANSSERIF" FACE="Arial" LANG="0"> I have found that if you are having problems with the white Teflon that it is almost always caused by over heat which softens the Teflon and it either is blown off of the header or pipe or splits longways. Look at your engine temp. head temp should be about 250 deg.F<BR>
if it is much above that something is causing an overheating problem which will eventually lead to Teflon failure first and possibly engine failure later if not corrected. <BR>
