I freshly built my b20v it is sleeved and is standard size for b18 pistons im running 11.34 to 1 compression ratio I've had alot of leaking issues front the front main seal I've replaced it 5 times used 2 different oil pumps with the same result a leak currently the leak is pressurized and leaking while the motor runs it is white and bubly which I think might be blowback but I don't know if its that or a headgasket issue some advice would be appreciated
