Woohoo! Dave the OM603 master does it again! Seriously, I really needed that outline! I'll be attacking the ALDA on the "slow" car this week. Regarding the cleanliness, engine degreaser at the local do-it-yourself car wash will do wonders! Although not QUITE as good as those hot water pressure washers. Gotta be careful with those around old vacuum lines - they can get blown to pieces!
