Hi all, I searched extensively but couldn't find anything on rebuilding the stock CS engines, so thought I'd start a new thread - My workshop (DS Motorsport in Coventry, UK) has pulled my engine and box to do a complete engine rebuild. They're terrific at what they do but also open to learning: I said I'd put a shout on here to try and scoop up a little of the wealth of knowledge and experience that exists in these hallowed pages.
As per the title above, this is a stock 2800cs rebuild; the car was down on compression on one cylinder, the core plugs were rusting, the whole thing was filthy and needed painting and it also leaked out of pretty much every gasket possible! As I wanted to keep my car's engine number that matches the VIN I decided to have DSM pull it out along with the gearbox (which as per this thread - https://e9coupe.com/forum/threads/5-speed-shift-linkage-bushing-replacement.20602/page-3#post-277349 is getting replaced anyway), to allow them to really tear into it and do the job properly.
As you can see from the pictures it's fully stripped, the block is away as we speak getting dipped and honed (no bore wear which is great). It will get OE or OEM rings, shells, head and rod bolts / nuts, oil pump chain and timing chain, (plus other wearable timing chain components - sprocket, guides, adjuster etc.). The car has a replacement AMC / Spanish copy cylinder head on it and as can be seen, the head has been stripped and inspected and pronounced healthy with the valves & guides within wear limits (also it hasn't been skimmed to death!) - One surprise was someone has smoothed out the intake ports a little, perhaps to match the intake manifolds (TBC when at assembly). Also I have a 123 TUNE ignition kit to go on it once it's back together so hopefully I should be able to get a lovely engine with plenty of power when done.
One upgrade it's getting while it's apart is to relocate the oil temp sensor to the (original / early) filter housing - I know some would say put a later housing on for ease of maintenance, but I have a stack of quality filter elements for the car and can just remove the whole housing / renew the paper gasket where it mounts each time to allow for a "on the bench" filter element replacement.
So for the build, does anyone have any pearls of wisdom to share? I'm just wondering what other potential tips / best practices are out there, plus the potential upgrades it'd be ideal to consider while it's out / all apart?
Thanks!
