JerryRigSpecialist Posted January 25, 2012 Report Posted January 25, 2012 (edited) I have a 7mm cub on alcohol setup for drag racing, it leaks coolant out out the radiator overflow tube, i replaced the orings in the head twice and pulled it apart again yesterday to find out that all the orings look perfect.. When it warms up and idles theres a slow steady drip but when i punch the throttle then more fluid would shoot out.. maybe a flaw in the head or domes? maybe put in new orings again? im out of ideas.. its a 1 piece billet head btw Edited January 25, 2012 by JerryRigSpecialist Quote
lt500rbigbore Posted January 25, 2012 Report Posted January 25, 2012 crack a couple eggs open in your rad..... Quote
Phelps Posted January 25, 2012 Report Posted January 25, 2012 when mine did that it was due to the wrong domes and was way too much compression. could also be a bad rad cap Quote
