yes and no, they still leak oil from the cam cases and timing chain cover, not usually from the head gaskets.
not a pressure leak, just minor dripping. Expensive to fix, usually runs about $3500 at the shop all said and done.
STILL A GOOD CAR!
The early chain engines-2010 and up tended to consume excessive amounts of oil. If it consumes oil the easy way to reduce it is to change from 0w20 to 5w30 oil and shorten the change interval
Get one. Preferrably 92-96 with the LT1. I have a 95. Love it for a fun driver. Rattles alot like all plastic cars over bumps. Mid 20's mpg all day long. When you first start driving one they are unimpressive until you start working them. The harder you drive it the better it gets. Clover leafs...
Park can be engaged, there is a place to use a small screwdriver or pen to bypass the shift lock and put it in park. All you have to do is look in the owners manual.
