Welcome to the wonderful world of SMB and 6.0L PSTD ownership.
I cannot give You any of the specific information You request because I too am a DIESEL DUMMY and I choose to remain so .
All my service is performed on or before schedule at the local Ford dealer wherever I happen to be when it comes due.
There is much valuable information in other forums including but not limited to: Trailer Life Forums, The Diesel Garage, The Diesel Stop, Oilburners.net, Blue Oval forum, Yahoo Sportsmobile Owners group, and my Yahoo forum @ http://autos.groups.yahoo.com/group/E-Series6LPSTDonly/
Although You'll read many horror stories in the forums, don't let them scare You, as there are also many Ford Master Diesel Service Technicians on board to lend a hand to us dummies.
I've learned a lot in forums, particularly how to protect my investment in the 6.0L PSTD.
Check them out and stay tuned here as several participants are also Master techs and/or self service afficianados.
