Oil explosions when revving engine

i would not bet my life on it,but check around the oilfilter, have had two engines where the oilpumps have had some kind of problem regulating the oilpreasure,ending upp with massive amounts of oil on the bandaged headers,twice resulting in underhoodfires. have also blown an oilfilter,good thing that happend in the garage,i still have the spots on the pillar as prof it got all the way to the roof.. changed oilpump and that fixed it.
