Whats up guys, just looking for opinions on what yall would do. Got to 98 Z28 with 197k on it and there is lots of sludge built up in the motor. I got the car when it had 168kto on it and the previous owner was using gtx 10-40 with lucas and i immediately switched to gtx 20-50. Motor still runs fine, i get valvetrain noise sometimes but i hold it at wot through first and second and the noise goes away. However, oil pressure drops to 0 once i let off sometimes and i have to turn off the car and turn it back on. I can take thr oil filter off and see all yhe nasty gunk that goes through my motor. So might yall have any ideas on what would be thr best thing for me to do, othet than swap or rebuild lol. Dont have the money. Thanks.
