As no work tomorrow i managed another few hours tonight. Got the engine out as i want to see why it was knocking and juddering so much. I found the culprit

Broke engine mount

Engine out!

I'm amazed at the condition of this original exhaust manifold is. It's very solid and the welds are as good as ever.

With the broken engine mount I would say the clutch is probably good but I think maybe I should change it whilst it's out. Hopefully that rules out a bearing failure too. The oil pressure was bang on. I've also got some bmc green paint coming.

One grotty engine bay that needs sprucing up....

One original 998cc cooper engine (except the later rockers)...

One drive coupling that's seen better days...

Anyone fancy some syrup? It's actually as thick. It took ages to drain out...

On to tomorrow....

The exhaust manifold is not original Cooper one, but main thing it’s design is not the best, I fitted a free flow maniflow to mine along with twin box rc40. Original manifold is pressed steel with external seams on pipes. Engine mounting well past it though, it’s good when it’s an easy fix.

That manifold is going then 😂 do you reckon it's from a morris minor of something?

Looks like a budget aftermarket one to me due to how pipes are joined

Oh problems oh problems. Went to take the clutch off today and the flywheel is stuck. The threads on the flywheel are buggered. I got some good heat on there as well but as soon as I got some good pressure on the nut it pulled a bolt. The bolts were brand new too. Not sure what to do. Should I tap a new metric thread? The fylweel is going in the bin anyway as the ring gear is worn out.

I had the same happen and tapped new bigger threads.I used metric as the local bolt supplier only stocks metric.I had to file bigger the holes in the puller.I may have just committed a sin using metric on a Mini.Steve..

Have you greased the bolt thread on the puller? It looks pretty dry in the photo.

Only the end of the bolt which is in the crank buffer as per instructions in the kit. I will release and grease now and see if it helps. Cheers for that

Started to clean the grime of of the engine. It's nice to see the original plate still attached. I did a schoolboy error as I wanted to undo the timing bolt to get the cover off as there looks to be no gasket there but now i have got the flywheel off I have nothing to lock the crank up with now. So I will have to get that side done first before doing the other. The picture at the bottom... I know the bolt is loose. I did it 😊

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.
