Ok here's my work area. Note that intake and alternator have been removed.



Since i already had the front disconnected I cut the lines and pulled out the front section so I can work on them on the bench... note that even snaking these small sections was a PITA

That didn't work out too well so i started with a larger section next time:







.... hoping that those slight nicks in the flanges dont lead to a leak.... but its pretty thick wall tubing so i hope im OK..
