Coolant leak, adding 16 oz of fluid every 200 miles or so. Just got my intake gasket(s) replaced - they bought a kit and changed them all - not exactly sure which one. Also had an engine oil leak too. Hopefully this has taken care of it all. Wish it were warranty work.

i have noticed a lot of oil leaking from the rear area of my engine. It is really to tight to see what's leaking, i will have it checked out and maybe it is the intake Manifold. Thank you!
Partially fixed under warranty. Rear gasket repaired w/o warranty.
