On the front on the heads there is a small diameter steel pipe to bleed the air out of the heads, which goes to the header tank (on my commodore). I have copied this setup on my L98, there seems to be quite a flow of coolant thru this pipe, which makes the tank quite hot, whereas I thought is was more of a reservoir,
Does anyone know if there should be some sort of restrictor on the flow, so that it keeps flow to a minimum? Thanks
