@mnm9194 Sure, the problem is you'd have to know what normal was. Some amount of blow by is normal, and that will go up with mileage. A more accurate and reliable way would be compression testing.
The Mazda 3 that I drive always had blow by since I had it. My brother had bought it brand new. I've read that 99% of four cylinder engines have blow by because they're overworked. Well, my engine doesn't burn any oil, but I think that it vibrates more than it should.
Ah, mine does about the same with 212k on it. Still starts up perfectly fine in single digit *F weather, and runs great otherwise. Keep an eye on your oil level, and drive it (and enjoy it) until you can get it rebuilt (like at 500k) ;)
can i use this test on a truck also its cause i want to buy a chevy 2500 hd diesel but i dont really know how to check on diesel engine :/

@derherr65 and how is that test ..the one where I have to put a hose in through the water deal and check the psi?

@mnm9194 I don't know the specifics of the chevy diesel. A compression tester and a good shop manual are required.

having the rings changed wouldn't cost so much would it?

Yeah Derjew is right, this worry over blow by is such shite, as long as you cold start and oil consumption is not excessive etc etc.

i have a 1983 240D. mine doesnt have blow-by. but when that time comes around how much would it be to rebuild the engine at a mechanic.
oh and my speedometer lights dont come on but all the other lights work so what do i do please help

blow by is irrelevant. Dont waste your time stressing out over it. if the engine runs, keep driving.

So strong spray, not good, blow-by is so common inside an engine like yours, but this "geizer" is so bad!
