hey guys, ive got myself worried here. OK, so the motor is freshly rebuilt about 6-7k kms on it, new oil pump when rebuilt. The car is running a 5-30 mobile 1. I was driving my friend home in the late evening and gave it full throttle going up a hill and the check guages light came on, let off right away and suspected it to be the oil pressure. After i drove him home i gave it gas and kept an eye on the oil pressure guage, sure enough at about 4000 rpms the pressure falls and the check guages light comes on. I really dont like the sounds of this... I was running regular oil for about the first 5000 kms and recently switched to full synthetic about 3 weeks ago. Ive been into the high rpms many times since then and no problems until tonight. Let me know what you think, thanks.
