You have to make sure the oil is for a wet clutch system. The oil lubes the trans and. Lurch only. It sounds like you may have over filled it.

Gear side crankshaft seal needs replacing.

Leak test to confirm.

Do not start motor until leak test has been performed.

When you drained the oil, did you take out the plug and the clutch cover off? Otherwise there will be too much oil!

Massive air leak between gearbox and crankcase. possibly a blown or poorly inserted seal.

Do not start it again until rectified.
