wonder if it would help to put some stp or something like that in it........I dont know a lot about these old trucks but my oil pressure sometimes will go down and come back up,,more so if Iam stopped,, on the move it seems to be constant.....dont know if I would change the oil pump unless Iwas pretty sure that was the problem.. how long have you had the 235, how many miles have you put on it?
