Garyk The blow by if you have it could be caused by a blocked PCV valve or line. The high oil pressure should be checked as stated above, electrical oil pressure gauges are notoriouly inaccurate..

Xpress Pop on a mechanical gauge first. NEVER go off of just one source.

Anything feedback would be much appreciated.
Before you do anything put a mechanical gauge on and verify your oil pressure then go from there
