[rear oil seal]

hi all yes I can tip engine forward no problem im just waiting on core plug now 

[rear oil seal]

hi all I have just tried tapping core plug with a sharp punch and it turns quite easy in block and does not look flat its quite curved so it might not have been fitted properly I will wait till new one comes before I remove old on

thanks for replies as you can see in photo scroll seal looks like it was replaced when engine was rebuilt and did not want to disturb it as it looks to be  sealing well iv been chasing oil leaks since I bought the car iv replaced seals in axle and rear gearbox and have cured most of them but it is a triumph so it has to leak somewhere

hi all thanks for all the responses the oil is running down the back of engine on core plug side only other side and all around scroll seal and crankshaft flange is dry iv even wiped a cotton bud between seal and crank flange and it was dry and the back of the flywheel is clean and dry what looks like drips on scroll seal bolts is gasket seal I will wait till new coreplug arrives then make a decision about the modified seal  which I have and iv borrowed a mandrel of john Morrison from Cumbria  it just seems a lot of messing about removing crank shaft I have also replace timing chain and tensioner when I replaced front oil seal which had a slight leak

hi all just managed to upload photos the seal fitted is stamped A 34 and I think is a standard scroll seal cant see a viton seal behind flange and you can see core plug is leaking and if I shine a light up behind crankshaft flange it is bone dry no oil at all

hi I have removed engine on my tr4a today to replace oil seal with a modified oil seal but after removing flywheel I have found the scroll seal is bone dry no oil leaking at all found oil is leaking from core plug in back of engine so advice please do I continue to remove crankshaft and replace with modified seal or just replace core plug save me stripping all  the main bearings and big ends and front timing chain cover as engine has done less than 5,000 miles since full rebuild iv tried to upload photos of scroll seal and leaking core plug but I think file is to big
