I know excessive blow-by is a mechanical issue with any given engine, and a repair is in order to ultimately correct it. My car runs great and I am not about to open up the engine because of it. But can changing oil viscosity help ?.
I was at the dyno on the other day and towards the last 500 rpms before redline my oil dipstick was popping out of its hole. My car is a 2002 Honda S2000, redline is 8900 rpms. The dipstick does not pop out at any other time other than the very top end of the rpm band. I am currently running Castrol Edge 10w30 oil. The O-rings on the dipstick are not worn, but I could look at putting on some thicker O-rings or a hold-down strap on the dipstick.
Looking at alternative oils I am thinking of trying Redline 5w40 or Amsoil 0w40. Any chance either of these oils could reduce Blow-by on my engine ? 5w40 is a recommended oil weight within manufacturer's recommended range, along with 10w30.
Thanks for any opinions on this.
