Thank You and keep it coming with opinions.

Dartman366...I will research the reverse cooling. That makes sense in changing the flow with the coolest part of the liquid coming into the heads....and also mentioned about a heavy duty oil cooler.

Indcontrols...what type of machine did you use for pressure. A regular deck pressure washer or something specialized, About how long of a process did it take you, Also , how much of the filler actually came out?

Zooom....Roger that on the Muri-Hydro acid. I will scratch that from the list.

Rebel....how long of a process to break that filler up if I just let it soak in a barrel of antifreeze? I didn't think that stuff was that caustic. Again, Just being curious.
