My ride has died
 

90 GXL with only 156,000 km eh! and I've lost compression in the front rotor. My mechanic tells me to keep runnin it and the Apex seals may pop up. I think he's nuts. It appears that Mazda is building disposable cars with an obvious design flaw and I'm looking at a $3600 touch to get back in the saddle. Any suggestions.

If you have a collapsed seal spring, it is *possible* to "unstick" it by driving it. (A collapsed spring will give you no/low compression)You might have carbon buildup so treating the engine with ATF is also something to try. If you have a broken or cracked apex seal, then forget it. 150k km is very short for a NA. Here on the forum we have several people with over 400k km (200k+ miles). If it is just the springs, then a rebuild should be very cheap, all you'd need to do is replace the seals and springs, it shouldn't be so much money. I'm not an expert on this one so hopefully someone else will chime in, but your mechanic isn't BSing you, what he said is possible.
