Watched some of your videos Joe.
The turbo fan slop isn't an issue - yet - but I'd keep my eye on it. Mine's about the same and doesn't make any noise.
However the play in the wastegate doesn't look too good.
Regarding blow-by. GMCTD had posted the following in a thread some time back in response to a CDR question I had:
Then, engine idling at op temp, pull the dipstick
Place a 36" length of 3/8" clear vinyl tubing over the dipstick tube
Place the open end in a container of water
Keep it much lower than the dipstick tube - prevents water in the crankcase
At 2000rpm, the water should rise in the tube about 1-2"
The higher the water level in the tube, the more restrictive the air filter - dirty, wet, etc.
Bubbles in the water means excess blow-by
If it blows all the water outta the container, ya gots really big problems.
But, the test should give you some indication of how much oil to expect thru the CDR
PM or email me if we can set my timing Friday evening.
Thanks,
-Bill
