You are right Rion. Plumbing the blowby gasses back to the dipstick will raise the engine's air box pressure, which could push out the crankshaft seals. Remedy is to just drain out the gasses.

Aris' 4JG2 may have excessive piston & ring to liner clearance. A compression test will validate this. If the engine fails the compression test, the only correction is an overhaul........ again. Very expensive!!!!
