After replacing the engine with a new long block re-built and engine working perfectly OK, I notice the clusters OIL pressure on the High side. All other gages look OK. Then after 20 minutes running the oil gage goes down to LOW, Gas gage goes to Empty, Temp gage goes to HOT but Voltage gage always OK.
Check codes and found a P0720 even when engine and Trans. Working fine with no trouble.

What do you recomend I do next?

I Check the ground from the neg. Of battery to the body (not going to core support) and check OK but clean and adjust. Then run a cable from the battery to the body (101) Test and found that the oil gage still moving towards the High side but do not reach the RED. After 1/2 driving gages did not went crazy as before but the oil still on the high side.

Thanks

Change sending unit but still shows high oil pressure. After deiving for a while the only needle not accurate is the oil, otherwise everything else is steady.
It might be the cluster?
