    Hey Guys I have a problem!! My suburban has started ticking very badly and its getting worse. my oil pressure sometimes drops very low and the ticking gets worse. I took apart the rocker arms and looked at the push rods and the push rods were grooved on the tip on the side that sits in the rocker arm and the rocker arm was grooved as well and this was on about two of them. I think that my oil pump might be going out but im not sure. it gets worse when its hot. if you guys have had this problem please let me know what it might be. and any suggestions on how to find the problems as far as diagnostics. Thank you all :glasses: Oh also it has 146k miles on it

    you might have diagnosed this youreself,oil pump sounds like culprit,to buy some time,do you think its worth going a little thicker with your oil,a good pressure gauge would tell you some more
