I'm waiting because the bad o2 sensor has become one with the header so I have to change the header too. a friend tried heating up the o2 sensor but nothing to be done only way is to cut the header pipe so I might as well just wait since I want to replace the entire exhaust system.
for the vacuum I was thinking of using the fog or smoke machine I got from ebay.
thank you for the information.
