Hi-

Well as I was gettng the TR6 ready to fire up for the spring season (
what there is of it here in New England) I noticed about two
tablespooons of coolant resting in the dished out portion of the block
behind and below the manifolds that attaches the engine mounts. The car
had been sitting idle since early November.

I tried my best to see where it was coming from, as there were not hoses
nearby. Best as I can determine it may be coming down from the head,
probably at or near the gasket. It may have been weeping ever so
slightly over the last 5 months of storage. Oil seems clear of any
coolant .

I put on a newly rebuilt head last summer ( 9.4 compression) and I
thought I did all the right things to make sure torque was properly
done. Copper gasket seal, retorque after first 20 minutes hot, retourque
after 1,000 miles hot. Total road time about 2000-3000 miles or so.

Question: How can I tell if this is a bad head gasket or , gasp, a
cracked head, or maybe even a warped head. Is it a visual thing or is it
evident in how it runs? Or do I need to tear it down to determine?

TIA for any advice.

*groan*
