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!
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.
Oil is pouring out I just had a new motor put in now my car now my car making a tapping noise and I'm useing 6 quarts of oil
