Ford 302 Blowing Oil Out Pcv Tube, Any idea what could cause this? The Ford Mustang Forum Have a 347 Stroker with Cobra valve covers and Edelbrock RPM Air-Gap intake - Car has a valve cover (VC) breather on the passenger side that twists in. Its the tube that gos into the airbox. Worn There is no place for the engine to "spit oil out", externally, under pressure, other than the oil pressure sender port/extension/sender or the oil filter Check the PCV hoses connected to the oil filler neck/cap, my Lincoln was doing that exact same thing, those hoses were clogged Keep the PCV and fix the blowby. There is no place for the engine to "spit oil out", externally, under pressure, other than the oil pressure sender port/extension/sender or the oil filter o-ring. I recently replaced the PCV valve as the crankcase air was venting into the air filter via a fresh air supply tube and dirtying the filter w/ oil The oil filler side of the old covers had a screw down oil cap/breather with a PCV valve which connected to the carb. It runs great, quiet, no misses, 15-16 on the highway. and when the motor is hot you can see the tube steaming or smoking. My problem is that there is an excessive amount of blow-by coming out of the hole where the PCV sits, the oil cap I am working with a '91 Ford F150 w/ a 302 (EFI), (118K). Anywhere else will be a leak or seepage and unless it's flung around by the fan, pulleys or balancer it'll be just a drip. I have an industrial i6 300 and I was trying to figure out why my exhaust 300 i6 blowing oil out of the PCV, oil cap and oil dipstick. fqwzm u93jzu zgu cepe 96 cugpl mlhxer tax2ru r0r vscc8
