A bit late, but i got GAZ GT5-2182B dampers at the front.
These are listed as dampers for opel manta-B, ascona-A, kadett-C, but they fit murena.
The only thing is the rubber bush hole is wrong. But i used the bush from the old dampers.

Very happy with these dampers.

Today was new windscreen day!
The windscreen surround purchased from France IS correct and leaves about 6 inches (15cm) over. The gent who did it took about 3 hrs and took great pride in his work.

That is great work Richard.
I ,my self, thought of having some spacers for the pop up headlights printed.

In keeping with my usual 1 step forward 2 back I am having a new screen fitted next week (£255) uero glass. Martin at uero glass put me in touch with a gent called Sel who has already been round to check out EOW. Sel who specialises in classic cars is collecting the glass which will save me £65 delivery. I have taken the opportunity to remove the screen myself to make sure I had enough time to wrap the roof ensure that all traces of sealant were removed around the screen and spray the scuttle immediately under the screen . I used Halfords etching primer and VHT wrinkle finish spray and it has come up remarkable well. The metal under the scuttle, which is not seen when the bonnet is closed, I used a black hemerite to protect from rust after cleaning with a wire brush and sanding. I obtained the screen surround from France and it does look to be correct one.

Roy lightens them a lot... More than Matra did on the S. On the S the engine side of the flywheel was machined away, on the ones Roy has done, they also scallop out the clutch side's edge, as shown here...

I took the sump off today and found the spring lying in the oil at the bottom.  It doesn't look damaged so I refitted it to the rensioner mechanism and it all seems fine.

I also came across an error with the head assembly.  It looks like a new Holbay cam was fitted and the rockers were not replaced properly.  3 of the 4 rockers with the lubrication ports are on the inlet side of the head. 

All in all, the engine is very good, just not put together properly.  It's had new pistons and rings fitted, along with bearings.  The head was refurbished with a new camshaft etc.  Once it is put back together properly, it should be a very good engine!  At least that is good news and makes this whole process worthwhile. 

After fixing the timing chain tensioner I looked for the original spring in the oil sump while changing oil. Using a magnet on a flexible rod through the drain hole, I poked around in the sump and, lo and behold, out came the spring.

Another thing that the 2.2 engine needs is a lightened flywheel as it is using the heavy standard Tagora 2.2 flywheel intended for the heavy saloon car!  I have modified a number of these engines now and all mine have lightened flywheels and I know the owners are impressed how that alone improves the pick up and acceleration.

Roy, how much do you lighten them by?  I've got my motor apart now and may consider doing this while I'm busy with it.

So, today was the day.  After lots of procrastination I decided to tackle the engine removal today.  By the end of the day I had the unit out, the engine separated from the gearbox and the head off.

The engine looks to have had a refresh in the not so distant past and everything looks pretty good.  I can't find any signs of why the cylinder head blew but will have it pressure tested for cracks nevertheless.  I'm starting to think that the head was not re-torqued after the last engine refresh and between that and the 20W60 oil that I used, caused the problem.  There was no overheating involved at all.

Lastly, the timing chain tensioner was lying loose up against the timing chain.  The spring is nowhere to be seen and is probably lying in the sump somewhere.  Lets hope it is still in one piece.
