I was thinking about the paraffin thing when I remembered I put a fair drop of oil down the bores that sat on top of the pistons so I guess the rings etc are OK. Cleaned the top of the block up tonight, some of the waterways are a bit gunked up. I have a spare block that came with the car I might be using that when I strip the engine down.

Paraffin being lighter than oil gives a more stringent test for leakage. Would this make a critical difference?

Hi all
not sure about the relative viscosities of oil and parafin but I know the oil was still in there a day or two later. bit more done today..had a scare when I found the big centre nut would not go on so I had to lop off the damaged threads and carefully shape the stud till the nut would catch and recut the thread phew! in the process my 30 Draper 5" vice from India snapped in half slow but rough!!! Head gasket is in place just need to clean up the exhaust manifold flange on the head put some copper grease on the studs and the head will be back on

it's going to take you all of couple of hours to check the compression of your engine with paraffin. Oil is too thick. If you find the engine will not start after you have replaced the head. You will have to start all over again and take the head off again . The sort of compression loss you described in a earlier post indicates to me that you have bore problems.

Bad luck with the vice. I'm a great believer in picking up old tools an refurbishing then. The quality is so often better.

Hi all
good news bad news
obtained a good secondhand vice from Mr Gruffalo at my local car boot he also supplied the excellent hub puller I have used previously. Said vice is now securely mounted on the bench and the old one is in the skip.
Now the bad news...did the paraffin thing in the bores and shock horror within 10 minutes 3 of the bores were empty with only one holding onto it's paraffin for a couple of hours...Hmmm
the thing is the plugs and vales had a nice pale brown deposit indicating the engine was running OK (40 years ago???) so what has changed, the bores were not rusty or scored, the pistons are firm in their bores, the engine is nice and clean not covered in oil blown out with excessive crankcase pressure...so stuck/broken rings?

ps check a new thread for mystery items found in the Consortium spares

Hi all
just came out from under the car...good news bad news again, bad news took piston out and the top ring was snapped, good news at least we know what the problem is!!! in my experience rings break when they are put into a bore that has not had the wear lip removed at the top of the bore...at bit of investigating tomorrow might solve if the rings have been replaced in the recent past. Anyone got any other reasons why the ring can break?

Hi
I assume if the pistons and rings were original the gaps should be OK..if they are replacement ones and the gaps were not set properly i.e too small? the rings would have less space to expand into when hot..a mystery

As I said in an earlier post lack of top ring lubrication they sometimes break or pick up.
When I strip an Appia engine normally find some rings broken.
As Harry said use some redex.

suspect they are original from all you have said about the car. Most re-ringing is done with a stepped top ring to avoid the lip issue. Are the bores scored? Will you need to get it rebored and new oversize pistons?
