Hey everyone i have a 92 camaro tbi 305 v8 and i did some work to it. After the work was done the car ran great no problems till the oil pressure gauge started falling as the car warmed up. So i checked the oil level was perfect so i looked around for possible leaks which i found a spot in the front from under the new intake i put in i didn't put enought silicone gasket maker so i took everything off cleaned everything and put a new live of the silicone but more then before and now no leek. So i thought the car was good so i took it out for a quick spin and the when you start the car the oil pressure was a little about the 30 mark and as the car warmed up the gauge went lower and lower till it was at 0. I was thinking of putting in a new oil pump but before i do that what else could cause this problem. What can be causing this to happen. Please if anyone can help i would greatly appriciate it. The work i did was a mild cam redid the heads new roller rockers intake throttle body spacer. Let me know thanks guys.
