It looks like you're progressing in leaps and bounds Alvin. I can't tell from the section photo of the engine block but is the weeping Welch plug the one behind the bell housing? Since you have the engine and trans out take a careful look at the subframe mounts for condition. It may be easier to do something about them (if required) now rather than later when you replace the engine/transmission combo.

Thanks enigmas for the advice re subframe mounts, will have to have a look. I see your discussion elsewhere on the forum on these. I already have issues with the gearbox mounts which have badly perished and appear to be unavailable. I have sourced some rubber from a local supplier which is almost the correct cross section, and am gluing onto the metal with contact cement. As the original was vulcanised, I am not sure how this will go. Re the rear seal, it is a continuing saga. I have been sent seals for Mk2 twice. The Mk1 has a smaller diameter crankshaft and a much simpler seal. Today I have sent my seals to the supplier in the hope that he can match them. I suspect P4 110 has the same motor, and seals may match. Meanwhile I am entering the comp for the oldest P5. From the WM it was the 45th export auto off the production line.

Alvin l wouldn't rely on contact adhesive for a mount. Google 'Mackay Rubber'. They are manufacturers and retailers of auto rubber products to the motor industry amongst other things. Their catalogue is very extensive. They're in Victoria not far from where I live. Given the age of your car and the coverage of oil over your engine and transmission I seriously recommend you check the subframe mounts, especially the secondary ones midway down the subframe. www.mackayrubber.com.au/products/automotive/

Work is on hold trying to access the crankshaft seal. Supplier has sent me 2 so far that do not fit. It seems that P5s may have had 3 different seals. Phil Nottingham suggested in an earlier post that these may be the same as later P4s, and I tend to agree with him, but my supplier is adamant that the part number is shown as "P4 Only". I have now sent him the seals removed from the motor and am awaiting his response.
Re the subframe mounts, how can one assess condition without removing the mount? They look pretty good and I cannot get any movement between subframe and chassis at the middle mounts using a lever. They are surprisingly clean, considering the amount of oil and grease floating around under the car. The steering all seems to line up pretty well. The front and rear mounts look very good, but the centre mounts are very difficult to inspect visually. Remember this is a Mk1 with no power steering and with drum brakes, so I tend to take it easy, although mainly country trips (that is where I live) at 50-60mph on the plains, and few windy roads.
I have emailed mackay rubber, but no response as yet.

Alvin it is up to you as to whether you want to check the mounts or not. I'm only suggesting it since you've removed the power plant. It's your car and ultimately your decision. With the engine/trans combo out of the car it's a relatively easy task, not so if the combo is fitted. At least check the centre 2. Raise the car under the front jacking point and the subframe will drop a little under extension. Then remove it so you can check it properly. The 3 litre six and DG autobox is not exactly a light weight lump. There's actually considerably more weight acting on the subframe than with a P5B.

Finally have sourced a crankshaft seal. It is the same as a P4 and my supplier believes that he has acquired the last available, certainly from his source in Birmingham, at horrendous cost (5 times the cost of the later P5 seal). Expecting delivery next week. I have had no response from Mackay Rubber.

Have now checked the subframe mounts. They were easy to remove, with bolts loosening with little effort, and are in good condition, with compression of about 2mm in the vice. As stated elsewhere, getting the 5/16 bolts back in is quite a hassle.
The issue of refitting the torque converter should be a different thread. and I will now try to set one up

That's good news about the subframe mounts Alvin. It's always worthwhile knowing that before the engine/gearbox combo goes back in! You would have rued the day had you found out later that the mounts were cactus !

Spoke too soon! I decided to remove all the 3/4 bolts and grease them. Front passenger side bolt is frozen and appears to be ripping the rubber apart!

The bolt is 1/2" NF the lengths are different to the front bolts which are shorter. Any decent nut and bolt supplier should have something suitable in stock. You'll most likely have to cut through the bolt with a slitting disc on an angle grinder.
See my post on subframe mounts for clarity on this matter. Don't forget to grease the bolts when you refit the mounts.
The centre mounts under the firewall seem deteriorate the most from my experience.
