You got my interest. What kinds of problems?

I'm hard headed, so it took a while for Kramer to convince me not to run more than a 7 psi cap.
Inquiring minds want to know... Why Bob?

With separate liners that protrude above the block deck, our engines have many places to develop leaks at high pressure.
The wet liner engine is far from rocket science. Getting the figure 8 gaskets and liner protrusion right is the only tricky part.

A better solution is to install a higher capacity radiator.
I did that too. A bigger radiator makes a big difference. On a TR4 it is pretty cheap and easy.

But without addressing the lousy coolant circulation you are still going get localized overheating. Combine that with really low block pressure and you get the classic #4 overheat.
