Driving HARD . . . with blowby

[Ben300SD]

I recently read the entertaining thread started by hottee18m regarding driving hard. I've been driving the 280SEL (huge car with a smaller engine) for over a year now, which has resulted in my developing a heavy right foot. Now that I own a 300SD, the 280SEL is parked and waiting to be sold.

It is such a great feeling to stomp on the pedal of the 300SD, let the turbo kick in, and fly up a 7% grade mountain pass at 70 mph in overdrive, while all the huge engined SUVs poke up the hill at 60 mph. I just love the torque that the diesel provides. Here is the problem: my 300SD has some blowby. The blowby is not excessive, i. e. my engine starts on the first or second crank and I have only added about 2/3 of a quart of oil since the last oil change (2400 miles ago), but nevertheless, the blowby exists.

I would like to postpone the act of rebuilding my engine for as long as possible, so obviously it would be best to drive the car gently. However, I find it hard to not enjoy my cars capabilities on occasion. What I would like to know is how fast the effects of harder driving will worsen my blowby. Should I never accelerate hard (unless I must for the purpose of remaining safe), or is it okay to drive with a little more pressure on the accelerator?
