Lots of conflicting search results regarding changing the Rover V8 (serp) cam bearings. Is it possible to do this with the engine in? Also, from what I understand you press the old bearings out..how do you do this with the last/smallest bearing? Is there a plug behind the bearing to stop oil escaping onto the flywheel...this would seem to be in the way when pressing the bearing out?

Yes that smallest rear bearing is the reason the engine will need to come out. And yes there is a core plug behind the bearing.
You will also have to have a special tool to fit the new bearings. I've so far failed to find one to buy.

What makes you think they need replacement?

Thanks Steve

I am creating a list of things to check when I replace my cam. In a few weeks I will be replacing the stealth cam for a MC1 as phase two of the mods is the addition of a supercharger. I understand the overlap of the stealth results in unburnt air/fuel escaping via the exhaust..bad news for the enevitable emissions testing...and the MC1 is better for FI.

Obviously hoping cam bearings are OK...happy to replace #1 but engine out would be a pita.

If your engine had done high mileage then an engine out refresh would be desirable before going FI.

I think I am going to do the FI build in two phases. Car currently has abt 45000km, and has a number of engine mods which produce good dyno'd power so I have no reason to doubt the engine and the spark plug colour is good.. During the cam replacement I'll check the cam bearings, compression and general condition. I have already roller rockers so that part should be fine. After reassembly I'll baseline the power again, then install the s/c. Not too concerned about the s/c install nor tune as I am already running a FI map with larger injectors so the only untested part is above barometric pressure..main concerns are engine cooling and charge temps.

Don't try and do cam bearings in situ, a futile exercise IMO.
