Accord/Torneo Oil Seals wont stop leaking
Hello everyone
The car in question is a Honda Torneo CF4, with a stock F20B motor that happens to be the Blue Top DOHC Vtec variant. For thos enot familiar with this motor, it's a destroked version of the H22 and doesn't have FRM sleeves.
Driven 206,000km
I've been facing an issue, started off with camshaft seals leaking, I replaced them with OEM seals and after a day they started leaking again, it was diagnosed that maybe the crankshafts are the issue since one of them had a slight mark on it, so I got them replaced and installed new OEM seals again, assembled everything back together, car ran fine for three days until one day I floored it, nothing abusive, just a 0-150km/h run and noticed drops of oil underneath the car when i parked it, removed the valve cover and timing belt cover, voila, one of the camshaft seal was leaking, I removed everything yet again and to my surprise, the crankshaft seal was leaking as well, so was the balance shaft seal. I got a whole set of OEM seals, after assembling the engine, I saw a puddle of oil beneath the car yet again, just two days later
Now what can be the root of this cause here? Any suggestions or ideas?
CR is 11ish and last I did a compression check a month back, all cylinders read 220 which is okay I think, for a motor that's done 206,000km.
Help will be appreciated.

Gotta be something with the way you're installing the seals. OEM seals come pre-greased so it's not like you're not greasing the lip and it's dry-ripping or anything.
What condition is your PCV system in? Are you still running the PCV valve or is it just vented to atmosphere now?
If the valve is stuck closed there may be crankcase pressure building up excessively. If the lines are gummed up with oil or crud it may not be pulling enough air through the crankcase to properly remove excess pressure.
