Well, was fun while it lasted... All 5 minutes of it.
The heatshield thing wouldn't give me peace so once again returned to Pick-A-Part and nabbed a front section of a similar heatshield and mashed together an extension. Quite pleased with myself with how it turned out.
Bolted up the exhaust with new hangers and fresh braces, started her up again, bled the power steering and cooling system, topped up oil, then dropped her down, torqued up the sway bar brackets and wheel nuts, ready for its first run.
Went for a quick run around the block. The clutch felt a bit weird and will take some getting used to. First time driving a manual BMW so not sure how it's supposed to feel like. Probably down to it being a double mass flywheel and the clutch not bedded in yet. Lifters ticking away as was to be expected, otherwise ran really well. Was absolutely buzzing to have her up and running again. All the good vibes got wiped away though as I checked the underside.

Not a small leak either. Left a good trail all along the road as well. Absolutely pissing out engine oil. Gearbox out it is...
I suspect it's the rear main seal. Thinking back now, I do remember being a bit unsure about it. I ran it in flush with the housing but originally I think it sat about 1-2mm proud. Thought it'd be fine, obviously mistakenly so. Remember seeing FCP Euro mention a special installation tool in one of their videos but then again others have just ran it in using the old seal with a block of wood so went with that approach. Must have messed it up somehow. Will hopefully see the issue once the box is out. Will just get this kit if that's the issue, don't want to trust myself with that again.
Bit disheartening after spending my whole Christmas break on it but it is what it is, learning things the hard way. Not giving up.
