    I recently had a pretty big problem with my G8. I blew a coolant hose and the car got pretty hot. I changed the coolant hose and ECT sensor and I burped it. While it was being burped it was jacked up and I recently bought some RP to do an oil change (was running Castrol Edge). So I decided to do...

    Hey guys. I been having problems with the beauty.:whine: A few weeks ago I had lost about a quart of oil. I have no clue how it lost it. I had checked under the car for leaks and it was bone dry. I'm wondering if it could be the PCV valve or something else that can be causing the problem...

    I have been planning out a few moderate boosted LS engines recently (for my G8 and Silverado). A few people around the net said something about getting above 10lbs boost in the LS3 (600hp and up) and you start having piston heat issues. The only thing I have found is the use of piston oil...

    I was about to go cruising with some buddies the other day, warmed the car up, and as soon as I pulled out of the driveway smoke starting pouring out of the exhaust. The smoke was whiter in color and not the standard blue from burning some oil. I pulled the car back in the garage, turned it off...

    I notice when I drive the oil pressure increases and holds at around 8 out of 10 bars (estimating). When I stop and idle, I notice the oil pressure gauge decrease to about 1 bar, and stays that way until I start moving again. Its been like this ever since I bought the car. Is this normal? Do...

    I was moving my trash can into my garage before pulling in last night and noticed a very shallow puddle under where my motor would be. I stuck my finger in the puddle and took a sniff... it's definitely oil. ABout a 2' x 2' puddle less than 1/16" thick. Enough to be alarming, but nothing...

    Just a heads up, pepboys has 5 qts plus oil filter for 29.99 on mobil 1. There isn't a limit, so I got 10 qts and 2 filters (for the next change). Also I ended up getting extended performance since they didn't have any of the regular stuff in 5w-30.
