[Peugeot-L] 1987 505 XN6 Cyl #1 Oil Fouled

The spark plug in cylinder #1 rapidly gets oil fouled.  

This could also explain 2 very recent incidents of rapid oil loss after highway driving, but no notable loss in short trips.  

Compression check as follows  

May, 2005 182,000 miles, Cyl # 1->4  

Compression, Dry 182 158 158 155
Compression, Wet 214 201 198 182  

The ³dry² reading for # 1 is suspect as the plug had a nice coating of oil on it; and the wet reading seem quite high.  

Could this possibly be a valve guide seal problem? What other tests or diagnosis should I do to confirm the problem?  

TIA, Charlie Lincoln
