I have a 1994 Jeep Wrangler S 2.5ltr. It does not have a pcv valve for me to replace. It was not desinghed on this year and model, it has a pcv elbow that allows breathing both ways. I am having oil blowing out my dipstick tube and connot for the life of me figure it out!!! My oil guage reads 80+ as soon as i start the jeep and stays there the entire time it is running. I figured it was just a faulty guage or sending unit. Not sure now though..... There is pressure building up in the oil pan from somewhere and pushing oil out the dipstick tube. I have read that this is called ''blow-by''. Well ok, how do you fix blow-by??? It was not doing this 2 months ago,,,, and then one day it all started happening. Please help.... is it an oil pump? or the oil sump? or the iol rings on the pistons? or the valves? or what?
Oil is also blowing into the air filter breather box where the pcv elbow goes in at. how do i get it to stop pressurizing itself to much and run like it used to?
Thanks,
Dan
On top of the valve cover there is a fresh air breather unit. Make sure the breather unit is not plugged.
Also the fixed orifice PCV should be clear. Find a tool that will go through the orifice and make sure it is clean.
Remove the vacuum hose and check it for cracks or internal damage. With the engine running, make sure you have vacuum through the hose.
Let me know when your finished cleaning the crankcase breather system.
