Hi folks I finally took the plunge and removed my turbo (to clean the vanes) from my Mk3 Mondeo 2.2 Was easier than I expected and thought the next stage would be easy..... remove the 6 bolts and heavy washers that screw into the manifold housing and lift out the turbo Not so. The 2 parts won't separate despite loads of penetrant, lots of hammering and levering plus the addition of heat (propane torch). I really don't know what to try next other than a few more weeks of the same. One of the issues is that you can't really hammer the turbo away from the manifold and there's not a lot to hammer on plus you'll end up damaging the alloy I'm also puzzled as to why I've never seen this mentioned despite lots of stuff online about removing the turbo c/w manifold from car and occasionally removing the turbo while leaving the manifold on the car  Garrett turbo c/w manifold on bench  propane  introducing some heat  smoke and WD40   using bar to hammer/lever on turbo assy and edge of manifold |

You haven't clamped or bolted it to anything?

I've taken apart a few and have held them by the alu compressorhousing with the exhaust side pointing down. I then hit on the edges of the exhaust housing, taking care to hit evenly around on thicker parts and not near the screw holes.
You need the hard impact to 'scare' it loose. Prying never worked for me.
But it it's just for cleaning purposes you might want to fill it up with ovencleaner (or is it called Furness cleaner🤔)?

Thanks for the advice but yeah I was thinking if I can't separate it may just need to clean it 'blind'. A lot of people advocate using oven-cleaner squirted thru a hole drilled in the opposite end of the manifold but I can't see how this is satisfactory as you aren't going to be able to directly clean the moving parts which are on the opposite side of your nozzle. I Have seen 2nd-hand units for sale at less than £100 so if worst comes to worst and I damage the manifold can always buy a used one. Think I'll have a last try with heat. Will remove the actuator unit and put the thing on a hotplate for an hour or so. I used this method to get seized studs out of a Jaguar V12 block and a Hillman Imp cylinder-head  hotplate is a good source of steady heat

I don't think that heating it that way will help much. Gradually heating the entire turbo makes it expand in total while you would only like the exhausthousing to expand.

True but often when things cool down again the seal is broken. Can only try

I find a big copper hammer is great for this sort of thing and doesen't usually damage the castings.

Loosening the bolts 2-3mm and leaving them in will prevent the turbo from falling apart and keep the holes with the threads round. Offcourse you need to be careful to not hit the bolts this way.😉
