engines work best off of compression not pinch. if you cant get that threw your head then there is no help for you. this thread is about pre heating engines which is best no doubt. but a heat gun is the best way to do that not a cooling fin condom. saying someone makes no sence when they clearly have a grasp on how things work and telling them to post somewere ealse when they are on topic MAKES NO SENCE
and to say someone doesnt like it cuz they cant afford it is a cheap cop out
