[TR] Compression Question

[terryrs at comcast.net]

Last question today (probably).  

For weeks before the head gasket blew, I smelled oil at the high end of the rpm spectrum, but not otherwise.  I expected this might just be coming from the breather pipe maximum engine load fills the crankcase with more pressure.  

On the other hand, is this a trouble-shooting variable I should know about before I ruin a second head gasket?

As ever, I couldn't keep this car on the road without you all!
