Well this isnt good.This is a pic of the black valvecover that was supposed to end our problem.Oviously it doesnt.I dont know what type of coolant was in here.(it wasnt Evans)We ALL have to switch to Evans RIGHT NOW till a aluminum cover is made for us.

I got mine from Ken's custom chassis. I got it for the $20 per gallon price plus shipping.He wrote on my invoice that new price will be $25 per gallon. Call them at 610-926-2820. Try for the $20 price, worst they can say is no....Get the NPG+.

I got it ordered!!! Thanks for the info. Do I need to flush the system before putting the Evans in???

I flushed my system and let it dry while motor was out.. Then added NPG+

Yes, you must flush your system.
Evans recommends that you do the following:

Drain the old coolant.
Flush the system with water.
Fill the system with Evans and run the engine until warm.
Let the engine cool.
Drain the contaminated Evans.
Fill the system again with Evans.

Done

When you flush the system do you have to use distilled water? I would think any tapwater left over would make the problem worse.

I would use distilled.After the evans is put in the second time leave the cap off the overflow bottle and let the motor run you will see steam come out the bottle.Let it do this for awile this will get rid of any water that is left in the system and allyou will be left with is Evans.
Like Dalerider said this isnt a permanent fix.Some who use the evans have overheating problems.This is all we have for now.

Please correct me if I am wrong. I thought last year, somewhere's I read that Dale's radiators have a design flaw. The water goes in the top and streight down to the bottom and out. The flow wasn't using all available cores. The fix was to have the upper inlet tube extended across the top of the tank to the other side internally. ???

The picture is a powdercoated valvecover from cannondale.The coolant found a way through the powdercoating more than likely the threads for the bleed screw.
