nice pics, Idrine85, thanks! Groove looks good to me.
Well the other vac. lines besides re-routing PCV...first is you want no Vac. leaks. Check condition of lines/hoses. If connections are in good shape, not dry-rotted cracked swollen oil-soaked, etc. then that's good. I've learned to check these lines thouroughly, assuming has bit me before!
But generally re-route PCV, then look at rest of em.
If a vac. hose/line is going to something like brake booster, a diaphragm, something that is vac.-operated but is a "dead-end" then I leave it alone, just check for vac.leaks. Vacuum operated means vacuum operated. Others like PCV and EVAP system can pull air/fumes through resulting in flow. If there is flow, then it acts as a vacuum leak, bleeding manifold vac. off, reducing the Groove's effectiveness. Ask yourself if the hose in question--if it connects to intake man. on one end--is dead end or allows flow through from a source,on its other end.
Might consider re-routing any EVAP system hose to the air inlet duct before TB, that will be a line from charcoal canister or fuel tank to purge fuel vapors. Power brake vac. hose obviously has to stay where it is.
It's good idea to connect a decent vacuum guage and measure manifold vac. at hot idle. Won't see pulsations in vac. from the Groove, those are way too fast--but a good vac. gauge is a primary tool to use..
Have you driven this Lincoln yet? How's driveability, power, tailpipe smell? Did you do a re-learn procedure for the ECM/computer?
Anyway Idrine85, we're glad you're here, that Groove looks good! Keep us posted and ask questions! Oh and it's cool to post using your name!
