Hey everyone i'm new to the forum and i apologize for any thread hijacks and whatnot but i have a 1990 supercoupe with a brand new oem bottom end in it new main/rod bearings, rods, ground and polished crank, new oil pump and sending unit for the glorified idiot light to tell me if i have pressure or not and i went to work one night and after i got in my car and started it up it told me i had no oil pressure so i let it set overnight in the parking lot then my dad said to h*** with it and was going to put a new motor in it so he went and drove it home, he got halfway here and the oil pressure jumped back up to normal and i drove it for about a month after that with no troubles and tonight it did the same thing, there is a slight top end tick, not a rod knock but like a loud lifter tick even though the oil pressure goes to normal above 2k rpm but below that it has no pressure and i'm out of ideas, it has new oil pump, pressure sending unit, motorcraft filter, quakerstate 5w 30, and little over 1500 miles on it since rebuild can anyone help me find out what is causing this nightmare? any help is greatly appreciated. thanks in advance
