XM 2.1 Rebuild
Hi All,
Here's a few photos showing the progress on the engine rebuild. They may have details in them that others may find useful - hopefully.
The decision to rebuild was based on the scruffy engine bay, increasingly hard starting and a leak from the injector pump (causing the hard starting). The clutch was a bit heavy too so I though a top end rebuild and a clutch would do the job but I've got a bit carried away.

Which led to me pulling the whole lump out -
So I decided on a few mods, such as blanking off the EGR -
A head port and polish after a test and skim, the port above No10 is the final finish-
A full seal kit in the injection pump-

After spending hours cleaning up parts with emery cloth I decided to buy a spot blast gun to see what finish it gave on rusty/corroded parts. It was a big mistake, brilliant finish in even the smallest nook or cranny so I went out and bought a small blast cabinet. Unfortunately this led to complaints about compressor noise so I started to look at ways of silencing the compressor or making a compressor setup using freezer parts and a big tank. There's lots of conflicting info about this kind of setup and oil mist in the air so I looked elsewhere. Eventually I found out about Hydrovane compressors, they're relatively quiet, powerful and top quality. They can be either constant running or stored air, single phase, 3 phase, 4 or 8 CFM. I found one on eBay, single phase, 2.2kW, 8CFM with a 100 Ltr tank. The only snag was that I then needed to upgrade the power supply to the garage. So a new armoured cable was run to the garage, 40A MCB in the main board then into a RCCD then the armoured then a metal clad fuseboard in the garage. So after more wiring I've ended up 5 individually switched fluorescent lights, 2 ring circuits and one circuit dedicated to the Hydrovane that terminates in a 'commando' socket. Hence the very slow progress on the rebuild.
Here's the Hydrovane in the back of my A Class-
All I can say is that finding out about these was a complete revelation, all that air and about as noisy as a vacuum cleaner!
So back to the rebuild.
Here's the result on a few parts-

After cleaning up the block and parts I started assembling a few pieces.
Block in Silver Hammerite and sump in alloy primer. New Valeo clutch fitted-
With the head fitted and sump painted, all threads cleaned out with a tap, cotton bud and air line. New bolts and a FAI laminated head gasket fitted-
Now with the cam carrier fitted, the polished ports and valves can just be seen, new cam and valve seals fitted from the gasket set and a used set of tappets to replace the very noisy existing ones, these have been emptied of oil and ultrasonically cleaned. All valves polished to a mirror shine-
Turbo bracket and oil return detail-
With the manifolds fitted, retaining studs and bolts clearly visible, all paper gaskets have been lightly coated with Blue Hylomar-
Finally with the turbo fitted after a rebuild-

Flippin eck, no wonder the clutch was stiff, that can't have helped!
Any idea of the mileage on it?
Looks like little or zero grease was applied on fitment.
When I did mine I bunged some grease (not too much ) on the shaft and it's now light as a feather
Nice work, there's them that do it properly and them that just chuck stuff together, you are the former

Thanks Dave,
If it's the original clutch then 147,000 but I doubt it. The clutch wasn't slipping or as heavy as the one on the TCT had been before I replaced it's clutch but living in a busy city I thought it would be money well spent, about £150 for the Valeo kit from AEP via eBay.
Here's how it looked after a clean up but before I decided to pull the rest of the engine out. Home made clutch tool in the bottom of the clutch housing. Shaft polished and new plastic bushes fitted along with the Valeo clutch and a light smear of grease in the bushes, hopefully not enough to attract dirt-
Let's hope it runs OK when it's finished.

Hi Dave,
She's done about 147,000 miles and according to the RP number was built in December 1992 and regsitered early in 1993.
I don't normally go to all this trouble but after having done top end rebuilds on the 2.5 and the TCT I couldn't wait to get my teeth into a 2.1. Hopefully this will be with me for a good few years when finished. Over the last couple of years I've been to various local 'classic' car shows and not a single Citroen is ever shown, so maybe I can change that, if so I won't be entering to win just to add variety to the usual line up.

After a clean up of the engine bay I found a split gaiter on the lefthand side of the rack. I may have caused this to happen by turning the wheel too far for the old gaiters to cope.
So the rack was removed and the subframe & bulkhead given a very thorough clean. The height corrector and Hydractive block were removed, stripped and ultrasonically cleaned.
HC and Hydractive block before cleaning - I've got a replacement sphere to fit too.
Although the LHM in the tank was bright green the height correctors 'store' alot of grime
Rack stripped, cleaned and painted. New Citroen gaiters fitted and a replacement track rod end - the gaiters were covered with bubble wrap and masking tape to protect them. Subframe thoroughly cleaned, painted and Waxoyled. Height Corrector and Hydractive Block stripped cleaned and refitted. Wiring loom tidied up using self amalgamating tape then clipped and cable tied into place.
As a finishing touch I decided to polish the steering rack cover. In the end I polished both sides hoping this will help keep it cleaner.

The injector pump is back on, the last nooks and crannies of the gearbox casing painted. I'm just in the process of getting together a cam belt kit. A genuine tensioner came off Ebay for just over £20 which is handy. The idler pulley from AEP has cost around £28, I did buy one from GSF for £11 but it's going back because it's plastic.
Luckily I've won an auction for a complete XUD11 not far away so that will probably end up donating it's injectors to get mine up and running.
