Stubborn AUA engine fitted to a 1.4 petrol BBY car refuses to start

Once the engine is repaired should the car be sold as an ongoing project car without an MOT?

I remember chipping in on the original thread and my understanding is that it is BBY originally, but the core of the engine was replace with an AUA but as Mac says core elements like ignition and fuel components were from the original BBY. It’s worth noting that the BBY has a different oil separator and plumbing so worth checking what type it has.
 
Thanks @birtyA2, good ideas,
I'll lift the car and get some photographs of that oil seperator.

Cleaned the interior yesterday evening. This morning used spray oil and tooth brush to clean the hinges then washed the door reveals. The coils and spark plugs were removed and cleaned along with the engine bay. The engine compression test was followed by an oil change. Hooked up a charged battery and to start the car.
Lots of cranking, some short burst firing then back to cranking.

Been extra, extra, busy
Cleaned the interior yesterday evening and this morning, I used the old spray oil and a tooth brush to remove the grease off the hinges before detailing the door reveals. This afternoon after the engine compression test I did a swift oil change. The coils and spark plugs were removed and cleaned then the engine bay given some light detailing. Hooked up the charged battery and tried to start the car.
It does a lot of cranking which is nice, with some short burst of a couple of cylinders firing for a second, then it goes back to cranking.
I'll record it

Better to log it. Tell you more than listening to it I think.

I have not learned remembered how to make VCDS logs. 🪵🪓
I'll work this out and make some logs by tomorrow morning.
🙂👍

Just go into measuring blocks choose three groups (suggest 002, 003, & 010 to start with), click Go on each group, check you have live data in the blocks.
Click Log button, and start the log. That's it, log is running. Crank as long as you can. Stop the log.
The csv file id saved in the logs folder.
Change it from csv to txt, and post it here.

Some things catches my attention in this picture.
Assuming this is a car built to have a BBY engine, and the engine swap was made with the intention to keep it a BBY car:
1. There is a part missing on the camshaft cover (actually the whole cover might be an AUA cover which doesnt have this part); a BBY has a device near cyl 3/4 by the lifting eye, which via a hose shall connect to the intake duct.
2. The EGR valve is the older type with plain metal housing. A BBY normally has the more black and plastic housing EGR valve.
Both things might contribute to the running problems seen in the video.

Hello,
Thank you all for explaining how to do this logging thing. I sat in the car with VCDS and realised I had done this before back in March.

Thanks for those ideas. The missing cam case breather can be found on my other BBY engine. I know exactly the item you are talking about. It is a bit of a worry that this car doesn't have it.
The old metal EGR matches the one on my other BBY. I ran adaptation for the EGR in VCDS, and both vehicles passed the tests.
:)👍

@Little Dog - New fuel clearly hasn’t worked. Could I sugest: Monty Python

Not filled the petrol can up at the garage yet. Car only arrived at 1530 hour on Monday 02/12/24.:) Give it a couple more days and I may become more like John Cleese.

@Howey - Reading the previous linked thread it would seem the spark plug being changed has generated a non start situation. This would be my first check along with fuses and anything that potentially could have been connected incorrectly during the engine change

Spark plug wells 3 and 4 had water sitting in them. Possibly is not water but coolant?

I will check back tomorrow and see what we got in there.
Thank you for the suggestion to check the plugs it was a good call. 🙂👍
Look at how little oil I got out of the sump. I say oil; I think it was neat fuel.

Anybody got a cheap 1.4 BBY engine for sale?

The spark plug wells are filling with coolant again, add this to the no oil situation.
Plus the last owner did a lot of engine cranking trying to get it to start with no oil in it.

Simplest solution is a low cost BBY engine swap or sell it for spares.

🙂👍

I'll dry out the wells and check again later today.

In the earlier video where the car almost ran was probably because I poured oil through the spark plug holed onto the pistons, then foolishly did a compression test.

The next day another compression test was done.

The timing tool lines slots into the two timing holes in the cam cover.
