my oil pressure is almost right on the H. Is it suppose to be that high?
Another thing is my temp. is about half and it has never been that high before. Any suggestion on these 2 thing that i could check please

 

Your temp sending unit could be going bad. Check and see if there's any wires that have worn places in them causing them to ground out

 

Only real way to know the oil pressure is to install a mechanical gauge and run the engine to observe it.

Half way on the temp unit sounds about normal to me, if you are worried you can inspect the t-stat to see if its working properly.
