[TR] Overheating Project

Had the same symptoms with my TR3 (TR4 motor) year before last.  Finally a friend on a drive told me that it was blowing out the overflow hose in intermittent bursts.  

No water in the oil, nothing coming out the exhaust.  Checked under the oil cap, sure enough there was the milky gray film present.   Problem was the head gasket and an unlevel spot where a water channel had been repaired.  Filed the high spot, checked the head and deck for true with a straightedge.  New head gasket and ARP bolts and all has been lovely since.

Fan replacement is just a matter of the 4 bolts - though there may be a pair of locking tabs to undo depending on who has been there before and what they did.

Certainly opening the petcock (or removing it entirely) should be part of any flush.  You may find it is clogged in which case fiddling in there with a bamboo skewer, stiff wire or even a drill may loosen things up.  As for where the water will come out if you put it into the heater hose connection - pretty much everywhere.

Have you assessed the condition of the timing chain and determined it & the sprockets are worn?

But what caught my eye was this statement...

The question is where did the fluid go?  If there was no obvious leaking or white smoke then there may be a failed head gasket letting coolant into the cylinders and out the exhaust.  A leak significant to show as coolant loss and overheating would not necessary have any visible traces in the exhaust.  One advantage of have antifreeze is that such a leak may be smelled more easily than it is seen.

But I am not sure there is much you can do to test that possiblity (short of head removal) at this point in disassembly.
