I need ideas....within 3 days this car has gone from no smoke to so much that there's a dense cloud of blue

 under all conditions except coasting. Suspected the turbo (should any play at all be felt by hand on the shaft?) but unsure if I should look there or to internal engine issues. It seems to make noise (valve train clatter plus a deeper slower one) that wasn't there before and has developed an oil leak at #1 between head and block. I'll update with compression test results as soon as time allows me to do one. I don't mind doing a head gasket but with 200K on it and the noise I'm not to sure its worth it. Anyone have a relatively low mileage 602.962 they're willing to part with? I don't want to part the car (its not perfect but its not bad either). 
Thanks!
