Can I test my PCV system, 99' V70 GLT 115Kmi, to see if I need to clean it? Car runs great, idles smooth, no smoke from dipstick tube, no oil on top of engine or oil leaks. Just a little oil in intercooler and pipes when I went to change the radiator - maybe a tablespoon full. Consistent oil changes with Amsoil since 30K miles. Uses ~ half quart of oil every 10K miles (been that way since purchased. Just trying to find out if I should tear it apart or run until it shows some signs. Thanks

Dave
