when my LS7 gets warm, at idle i have 10-12 lbs. of oil pressure. at 60 mph, i have 20-24 lbs. of pressure. has any one else had this problem with their Z06? mine is a 2013 427 convertible. it really scares me.                                                well we have some new information on my engine. GM rep has been down to see my car and decided to have an engineer in on this, so the engineer called and wants the engine completely taken apart and every step and procedure documented and pictures taken of every step. this is to be done this week. the engineer thinks that the aluminum particles that we saw aren't aluminum at all but titanium from the side clearance of the rods. this is food for thought guys. so, here we go for a complete tear down. wish me luck.

well, it was titanium and once they pulled the engine the rods on the front two journals had 1/8 of an inch clearance(at least) each. so new motor was ordered and all hoses and tank and oil cooler, because all this stuff was comprimised. so, the new engine was back in and still had to have all the stuff hooked up. should have it back sometime next week.



got the car back. it was great. smoothest running LS7 i have ever owned. (i have had 3) thank you GM.
