So I am running a fairly well built 440. But can anyone figure out why I may be building pressure in the oil? Oil was spraying out everywhere and eventually built up enough pressure to blow out my evac pressure relief valve thing off of the valve covers. After the heat the motor, hood and me was all covered in oil. Not full on oil but lots of drops everywhere. Any help as to what I may look for would be helpful. Here is the video link. youtu.be/dg2GEsWNE9A |

I also did a compression test and all cylinders were at 100 except one was at 95. Is that about right for compression?

Notice at the end of video,oil on the camera after the hose blew. Did you have a oil/water mix in the radiator ? Not saying you did it,but internal damage from the motor.What's the oil look like ? That 2 min video is that from start to finish ? if so, dam that motor got hot way to quick.

I do have water in the oil so figured I have a bad head gasket but can't see any signs of oil in water but don't know. There was about 3 minutes of derby before that didn't record |

Compression in the crankcase, blockage from the ccv, etc. If you had a blown head gasket, it still wouldn't create the pressure in the crankcase. You're problembis that there isn't a good enough vent. Your ccv (breather) is being a blockage. Run it without and you probably won't have issues. You gotta understand one thing, pressure can't build if you have an open system. The only thing that should cause a build up of pressure in the crankcase is the pcv valve. Actually it's intended purpose for emissions bs.

Make sure your dipstick is reading correctly. We have used after market dipsticks and modified dipsticks that did not fit right or were too short. This caused us to overfill the engine with oil and we saw the exact same issue you are seeing now. Once we figured it out we never had an issue again. Just one more thing for you to look into it.
