14/06/2014 Now that all the parts have been bought and the block/head are back from the engineering company, the assembly starts in earnest.
The brand new crankshaft had a very small “ding” in one of the webs, you can see it in the centre of the picture. As there isn’t much room inside these engines, the dinged part kept hitting the block as the crank went round. It wouldn’t have sounded good running like that so I carefully fixed it with a file. All sorted.
As this was going to cost a few £ to sort out, I took the opportunity to replace the water pump and the oil pump. These are the silvery bits on the front of the engine. The engine has to last a while so it made sense to replace those items while everything was in bits.
18/06/2014 I tried turning the engine over with an electric drill to check the compression, this probably wasn’t the most sensible thing I’ve ever done.
It all seemed OK until after about 3 “pumps” the pressure got up to near 200 PSI the drill would get ripped out of my hand or spin round and hit me as it came round.
At least all the cylinders are making high pressure with more to go – this is a sign that all is good with the engine so far.
19/06/2014 Well that’s it for now. The engine has been put back together about as much as is possible and I await the weekend so I can get it all back in again.
I have a few odd jobs such as replace the fuel pump and the coil. These will get done on Saturday and probably best to do them before the engine goes in so there’s more room.

Just the easy part to do now Dunc. Your work is impressive, you are really in the wrong job! Just make sure you run it in properly, I’m assuming it is still needed these days.
Hi Steve, the bearing and piston clearances are spot on so it will need minimal running in. 600 miles without giving it full bore, then throw the oil and filter away – that should do the job.
