Tap, Tap, Tap...

restore is for scratched cylinder walls,,,and it does help,, i used it in a ford turbo coupe with 145,000 miles on it every oil change,,,

i used the rosline once in a 66 dart 273 car,,,after the rosline the rear main started leaking,,,,

you may have worn rockers,,push rods,,valve stems,,could be a lot of things,,,you are going to have to DIG IN and take a look,,first figure out where the niose is comming from,, take a valve cover of an dsee if your getting proper oil flow to start with,,,you may have clogged oil passages not allowing enough oil to the lifter area or rocker arms,,
