I noticed a small oil leak a few days ago, and I isolated to the oil pan gasket. I reused my old one when I built my new engine, so it was tired.
I got the oil pan off and noticed that the remnants of oil left in it looked like nestle quick. I was about to cry. I didn't want to replace a head gasket because I had internal bleeding. You know, coolant in the oil.
As I am draining the chocolate milk from the oil pan, I find 3 large (almost 1 inch across) chunks of something. I thought to myself: ****!!! My brand new engine is breaking apart!!!
I cleaned up the chunks and put them together. THey were pieces of the timing chain tensioner. I have no idea how long they were like that, but I know that every time I nailed the throttle, my cam advanced itself from the centripetal acceleration acting on the chain.
That also explains the water in the oil. THe timing tensioner bolt hole goes through the water jacket.
I guess I am walking for a few days while I get one of these: new timing set
I am gonna just put that thing on and hope to god that my engine isn't riddled with foreign object damage. That would suck if little pieces of the tensioner were blocking oil galleys somewhere in the block.
As for the milky oil, I will take the car to a dealer and get an oil flush done. I should take the motor back apart and re-inspect everything, but I REALLY don't feel like it.
Anyways, that is how to make your GM 3800 II into a VVT motor.
I am amazed at how brutally tough the 3800 is. Huge chunks of mine have blown off and it keeps right on running, with plenty of power.
