My £52 engine from Ebay has gone to Cambridge Rebores for a liner in No2 cylinder, 2 helicoils and a minimal skim. I have been warned that there are some liners made in India that have a high copper/brass content and wear very fast so I specified Westwood. It should be ready at the end of this week and the resto fund will be £160 lighter. The bottom end on the Ebay engine is not too good but my old engine is not too bad. So I should be able to use the crank, rods and the new pistons from the original engine and the block and mains (same size) from the Ebay engine.
It took a little time to explain that the threads are coarse metric. _________________ 1936 Morris 8 Series 1

I have got the engine back and set to rebuilding it. One of the white metal bearings was cracked so I found a good one on the Ebay engine but is was a bit tight. I spun the conrod around a few times and undid the big end then lightly sanded the high spot. After doing this a few times the bearing felt good so I continued with the rest of the crank assy. Then the camshaft went in, timed up and then I realised I had left the split pins at home. I had the old head gasket so I decided to put the head back on and do a pressure test on the water jacket. Just a simple hand over the lower pipe and mouth over the upper pipe and blow.......nothing. The air was coming out of the NO 2 inlet. The helicoil thread had been tapped a little too deep and had chipped off a piece of metal between the water jacket and inlet. So back it went this morning and with a lot of head scratching nobody was 100% sure how to sort this one out. So I have left it with them and they will phone me when they come up with a way of sorting it. I told them it had been sitting in a museum for 30 years so a bit longer will not hurt it. _________________ 1936 Morris 8 Series 1

Nic,
I really don't think you should have sanded the bearing. The babbit is really soft and could have retained some of the grit. They are supposed to be scraped, but you probably know that .
As to your leak problem. A friend of mine had a similar problem and made a short brass threaded plug to go in the bottom of the hole. It would need to be the helicoil thread (before the coil is fitted) of course. Another thought just occured. What about a ball/slug of solder/lead dropped into the hole prior to refitting the stud?

Hi Art, The babbit seems to have hardened over the years and I do not have the correct tools to scrape it, however I will pop it out again and make sure there is no contamination. A plug in the bottom was one idea and will most likely be the answer but it is not possible to see inside the water jacket where the damage is unless I borrow an endoscope. Whatever the answer is water must not get into the inlet as I can hear the sound of snapping conrods already. _________________ 1936 Morris 8 Series 1

The slug method did not work as there was nothing at the bottom to hold it. They even tried to braze the hole in the inlet but as the hole was about 30mm into the block it was not possible so I reluctantly agreed that chemical metal was the only answer. I will pick it up in the morning. I have also had an estimate for the repairs to the bottom of the body £500 - £700. There goes my budget! _________________ 1936 Morris 8 Series 1

The engine is now ready to go back into the chassis
I will be getting another quote for the bodywork tomorrow
I had to go to a physiotherapist yesterday as I put my back out lifting the engine. I must remember I am over 50 not still 20. _________________ 1936 Morris 8 Series 1

Looking good Nic, has it been pressure tested? or do you find out wether your leaks fixed or not when you run it up for the first time. |

Yep it was pressure tested and they did a vacuum test on the inlet tract so with any luck the water, oil and petrol should all stay where they are supposed to be. _________________ 1936 Morris 8 Series 1

It is now getting serious. The body will be delivered to the body shop on friday and the chassis is going to work on tuesday.

The body has gone to the body shop and I had to pay it a visit, a bit like one of our family in hospital. This is a first fitting and the panels will be cut to shape later. It looked at first as if a small amount of metal (rust) would be replaced but as it always happens it was a fair bit more before good metal was found. The chassis just needs a small patch and hopefully the body and chassis will be back together in a couple of weeks.

I knew a pallet lift had a propper application.
How much crud can you get from 1 chassis, 2 carrier bags. _________________ 1936 Morris 8 Series 1

The body is now sitting just above the chassis while I do the easy welding. I have got a new set of flexie brake pipes and I am waiting for a set of engine + gearbox mounts plus a sleeved slave cylinder. I picked up the relined brake shoes and clutch last monday.
I had a look behind the headliner and it is not good so I will have to replace all the wood for the Morris. I will keep all the rotten wood and have a fire when I have finished.
I will post some photos soon. _________________ 1936 Morris 8 Series 1
