Thought I'd see what you guys think, is this a good way to diagnose? My new FPR is paid for and in transit anyway, so its getting changed no matter what. WIll keep posted.
"The only real way the regulator will fail is when the diaphram gets old and cracks. The easiest way to check for this is to pull the vacum hose off the top of the regulator and rev the engine. If the regulator is bad, fuel may squirt out the vacum port, meaning the diaphram is broken. When the diaphram fails, fuel is sucked into the intake and the engine runs extremely rich, making a bluish smoke in the morning. Some of this leaking fuel will get sucked into the crankcase through the pcv system, making your oil smell like gas. Bad pressure regulators should be changed as soon as possible because the extra fuel can make the engine backfire through the intake, which can kill the air flow meter"
