Data point: 53k mile 2003 C2 Cab, oil changed every 3-5k, IMS removed due to leaking enough to drip on floor after run. Polish bearing, perfect condition. No grease evident, filled with Motul XS 5-40. Tube had oil in it also, smelled relatively fresh not putrid like some.
Used my new P 254 Engine Support Bar for the 996 yesterday
It makes pulling the trans alot easier. Beats using a floor mounted screw jack under the engine.
You can tilt the engine/trans to get clearance to pull the brackets out and replace them, move the lift up and down for bolt and slave cyl access etc. Also enables engine tilt to match trans during installation.
Shop owner liked it so much he bought it from me to use in the shop.
Oh yeah we were pulling the IMS because it was drooling so much. 53k on 2003 C2, Polish bearing, looked and felt perfect no play, no grease just Motul 8100 5-40.
