What is compression blow by?
Compression blowby is air, fuel, and exhaust gasses slipping past the piston rings into the crankcase.
What happens in the upstroke of the piston in the crankcase in a four stoke engine?
On compression the air is compressed, and on exhaust it is forced out of the cylinder.On compression the air is compressed, and on exhaust it is forced out of the cylinder.
You have oil leaking out of your air filter on your Briggs and stratton engine?
the valves or rings are allowing compression blow by to enter the crankcase which causes excess pressure that is brought to the carburetor by the breather tube. your engine is getting tired or you have too much oil in the crankcase.
Why does oil smell like gas but compression is good?
Not knowing what vehicle and engine you have you may have a faulty fuel pump leaking gasoline into the engine crankcase.
How can you tell if your head gasket is blown in a 1994 Cadillac concourse?
Look for white smoke from the exhaust and oil and water mixing in the crankcase and radiator. A compression test would identify this also if two adjacent cylinders have low compression.
How does fuel get into the oil on a td5 defender?
If you're getting gasoline in the oil, then you have bad piston rings that are allowing gases into the crankcase. You can find which piston(s) have bad rings by doing a compression test; a cylinder with bad rings will have lower compression.
What do you mean by pcv in motor vehicle?
PCV is positive crankcase ventilation
What is mean compression ratio of 71?
It means that before the compression, the volume is 71 times larger than after the compression.
What is a pbc valve?
Did you mean PCV [positive crankcase ventilation]....that valve helps keep engine gasses from going to the atmosphere but wont allow intake pressure back to the crankcase.
What does it mean if you have oil in your air filter?
Check the PCV (Positive Crankcase Ventilation) valve. Failure in the pcv ? Usually it's piston ring blow by caused by worn piston rings. Get a compression check. I'll bet this has at least 100K miles on it. Its called "blow-by" you need to replace the piston rings. Over time the rings and cylinders get wore out allowing oil to go past the oil compression ring. Also check to see if there are bubbles on the dipstick to your oil,thats an indication of bad rings too, its gas in your oil. Check if your PCV (Positive Crankcase Ventilation) valve is ok
What is a PCF on a Ford Expedition 2003?
Do you mean PCV ? - ( Positive Crankcase Ventilation ) valve
