Hi. Have an 81 Aircooled. It’s had a very slight oil leak since I bought it 7 years ago but it’s never bothered me and never had problems on the MOT. The last year or so when I’ve challenged banks/inclines therefore using a lot of revs, when I stop to park up the oil absolutely pours out. It’s nowhere as bad on a straight run but when I’m using revs in first or second gear it is pretty bad. All I know is it’s coming from underneath the engine but at a loss as to the problem. Had a guy look at it last year and suggested the oil cooler but in the end didn’t seem to want the job.
Cheers.

Pushrod tube seals are the usual suspect.
The covers need to be removed, to see.

We would just be guessing without knowing what area it is coming from. Put some pictures up so we can see the area.

The oil is running down and falling from the bottom of my oil filter. I know it’s not the oil filter that’s the problem but that’s where it ends up before it drops to the floor. I’ll try get some pictures up.

You need to spend some time cleaning up the area and the areas above so you can see where the leak is coming from. Having brake cleaner as a spray will be helpful but you'll use more than you expect

check your rocker covers I had one that had rusted through and there was a small hole in it which was letting oi leak through it, changed the cover, gasket and spring clip took half an hour and the parts were less than a tenner from Brickwerks.

good luck

Oil pressure switch is another candidate......
