[Roadsters] Overheating question

[Matthew Cox]

Thanks for the tips so far everyone. Just to clarify, I have a 67 1600. Sorry about that...
   
  Keep the ideas coming!

  John,
Where is the oil flow adjuster? I never heard of that before.

Do a compression test. This really sounds like you blew a head gasket :-(

With everything together and the radiator cap off, at idle do you see
bubbles in the coolant? That would be exhaust gas from a bad gasket...

Hmmm - sorry, I didn't note: 1600 or 2000? Either way it should be
good and slimy up there. On a 2000 the spinning camshaft will throw
oil all about - if you leave the cap off while it's idling, you'll
quickly know it :-)

On the 1600, there's an oil flow adjuster that if it's screwed down
it'll starve the valve train.

If the bearings are really bad you'll have great flow and zip pressure.
No pressure = nothing to the top end, and likely not much to the
cylinder walls. That could heat things up quickly :-(
