Hey, well I finally got around to doing the compression test on the  
93 Pearl as I'm thinking of selling it.  It consumes a bit of oil,  
and when you jump on it, can smoke quite a bit....then other times it  
seems fine.  All 8 plugs look healthy.  The numbers are  
125/130/125/130/125/125/130/125 with no change when I put some oil in  
the cylinder.  My book for the 3.6 shows 145-189 new, wear limit  
109.  Just wondering if the 4.2 is the same?.  There's a small weep  
of oil underneath, but nothing that actually hits the ground.   
Wondering if anyone can concieve of anywhere the oil could get right  
into the exhaust manifold, as the plugs look way too nice to be  
burning the amount of oil it's burned on a few occasions.  Could it  
be sucking it right out of the exhaust guides at full throttle into  
the manifold?  Didn't go thru as much oil when the girlfriend was  
driving it.  Idles perfect and quieter than the other 2 cars, and  
get's up and goes on the highway(except the motorcycle behind me made  
a motion like he was holding his nose).....Hope all's well...Tom
