Try this replace your powerstage this sents power to the coil,these overheat and die.Sometimes your will run,but after warming up it dies.This powerstage is mounted on the inside finder.Find these at your junk yard.

This is how I change the trans fluid in my volvos. * Obtain either IPD's transmission flush hose or a clear vinyl or plastic tube (3/8 inch I.D.) about eight feet long, three or four gallon milk jugs calibrated with a permanent marker in quarts, and a transmission fill funnel with a long, thin neck....

Piston slap is common, at start up what type engine oil are you useing?I like Max life 10 w40.

Have you check you fuel pump relay?

No its does not,because it vents its gases back to the turbo,it just has an oil breather box,function is to provide a low-velocity space for fine oil mist and droplets to collect (or coalesce) into larger drops that can flow back into the crankcase.

Comes on every 5000 miles, it has an reset button.
