Are the head bolts blind in these blocks?
If not you could just have a one of the top row of head bolts leaking into the valley once pressure builds up as seen many times on SBC motors of yore. It's time to block stuff off and apply a pressure test to nail it down.

IAII and MR-1 headbolt holes aren't in the water jackets.

I believe they have a pipe plug fitting in there and they just flat mill it. Its the same as the IA2 set up. Good luck.

Mine did it in Vegas last year between races. Was fast at the first race and it kept slowing at the second race. Thought a bearing was going away took the filter apart and saw coolant, must've had 3 quarts of coolant in the crankcase. Long story short took the motor apart when I got home could see the trail in the valley but couldn't really see anything in the deck. When I put it back together I saw a hairline casting flaw so I smeared clear RTV the spot it going to get stop leak when I get it running again. I put stop leak in it when it happened and that did stop the leak.

You would think there would be some qc on castings before being shipped.

They should make it right if there is a problem. I doubt you will get any money back for parts or machine work as it probably should have been pressure tested from the start. For the most part race parts cary no warranty.

A friend of mine had the same problem, it took forever for them to answer the phone {as usual}, then they sent him another block . It did the same thing, then they would not answer the phone.
