Looking good, if you haven’t already got them use the qh type nylon needle roller type driveshaft couplings when you refit engine rather than the rubber ones.

They are in my basket on minispares at the moment. I need to sort out the flywheel and clutch. I have been thinking about an MED stage 1 clutch as it's ready just to fit but I am swinging towards a new ring gear on my existing flywheel and keeping it all original.

The ring gear doesn’t look bad on pictures, I have changed one in the past and it needed heating to fit and you only get one chance to get it right. I have just used a blue diaphragm and new standard clutch should take everything a 998 can throw at it. I did use a steel cooper s back plate as well.

Took the head off again as I noticed some water coming through between the head and block at the back seam by the engine steady. Upon a thorough investigation I noticed this pitting between the centre bores on the block. The pits are inside the fore ring and the gasket seat feels flat to the finger nail. Is this asking for trouble?

I'm wondering if I should tear it down and rebuild it properly.

It looks like the block needs its deck skimming. You won't know how much until you get the rest of the engine built and see how far down the block the piston tops come at TDC.

Very true. Shame I would have to rebore this block and use different pistons. I'm going to give a new gasket a go and see what happens I think. I do like this mini but I think my heart will always be with an early mk3.

The past few days I've been continuing with the engine cleaning. My bmc green paint arrived.

A picture after the first coat. Two more to go...

The timing cover had been fitted with no gasket and was contributing to an oil leak. So I have given it a lick of the green whilst off.

Looking forward to getting that side sorted out then I can turn my attention to the clutch.

I have started to strip the bulk head back and give it a fresh paint and general tidy up.

I have ordered up some new aerosol RD9 paint, lacquer, primer and some aerosol pre coat so i wont get any reaction when using the new paint on old. That should arrive on Wednesday so I have plenty of time for prep.

Had a quiet day in the garage today. Just rounded up these parts to clean up and paint. I'm going to take both master cylinders out and see if I can get then a lot cleaner with some Autosol and elbow grease.

A great looking project and doesn't look to have been too messed about with over the years which is always good news

Yes coming along well, following this as it brings back memories of my project. I like mk2 cars and they are often missed out as people go for a mk1,

Thanks for the nice comments guys! It is pretty much all there except a few bodge floor repairs that will be sorted properly in a few years when needed. I'm still looking for some rear opening glass in clear but with lock down I can't get any.

Daz1968 I could only wish that my car was as nice as yours. It's stunning!

Some prepping for the new bulkhead paint. Both master cylinders removed, rubbed down the shabby areas and a drop of rust treatment.

The master cylinders before cleaning...

Then one after a rub down and Autosol. Looks so much better. Going to do the rest and hopefully will look great again.
