Found these interesting..
Can`t decide if its a gimmick or has some merit in the marine world.. how hot do springs get?

all our race engines had spring oilers in the valve covers. the springs get alot hotter than you think on a high rpm engine (ours ran 7800 all day). the new nascar engines actually fill the entire valve cover with oil to help pull heat away from the springs. you have to open a valve on the back to drain the oil to the pan before you pull the covers off.

I run spring oilers, but the oil comes from a small hole drilled in my T&D shaft rockers. In my case, the oil for the springs runs up the pushrods. Where does this spacer get the oil from?

Thats where I figured the oil would come from. Personally, I dont like that idea. Although I understand that oil pumps pump a whole lot of oil, I am not to happy with taking oil from a port that may be sending oil to a vital part, like the bearings. In this case, all of the springs would be getting their oil from 1 port, well, maybe 2 if you were to split the 2 sides of the engine. Sounds to me like it may be a substantial amount of oil be taken. In the case of having your rockers drilled, the only part that looses a small amount of oil is roller tip of the rocker.

I think these are more practical than people think. A spring is made of spring steel the only way it holds it's shape a spring tension is thru a tempering process. Changing the temperature of the spring could result in a loss of spring pressure. In theory if u got the spring so hot, that is to it's temper temperature it would just be a soft piece of steel. Not that this could happen in a head application but that's the science behind it.
