I have to ask was it a motor meister engine.

I hate to inform you that there likely be two answers given for this. Yes and No. The camps are divided. Probably in a perfect world where you are able to get the case halves togeather and torqued using a hardening sealer you would not have the problem you are describing.
Personally I could not get the case togeather fast enough and had thick areas of sealant that leaked and also likely held the halves slightly apart. That is why on the reseal I used hylomar, a non hardening sealer and so far it has worked great.
According to the porsche service manuals the 574 does not even need to be cleaned off before reassembly as they say it will dissolve and reharden. Testing did not show this to be the sitiuation. I believe they also state you have around 20 minutes to put the halves together that is somewhere around one every 20 seconds. Professional engine builders can maybe do it. Me... not quite so fast.
