what are the symptoms of a split block?

my car is running pretty much perfect, but i have a lower oil pressure than i normally do on my autometer gauge. im just wondering what the symptoms are, and like i said EVERYTHING besides the oil pressure is fine, makes good power still, drivebility is fine, idle is good.

How low is low. If only a few lbs low, i wouldn't worry about it. If its like 10 or more, then you have a problem. But i think with a cracked block it would be making a crap load of noise out the bottom end.

its a high volume pump, before i used to cruise with like 50-60psi now it cruises at like 40+psi, the pressure does go up nicely when given more throttle but this has me MAJORLY concerned, it used to idle at like 40psi now the scary thing it is idling at like 20psi :shock: im kinda leaning towards the nylon line being krimped(yes i know why am i running the nylon line in the first place) and the valve train/bottom end makes no noise what so ever.



Thanks, Scott

It could also be your guage starting to go. I'd get a known good guage and check oil pressure right off the engine.
