hello again,
I recently had a post on here describing a ticking clicking sound that was driving me nutz. Thought I would share that the source was header gaskets that were total crap and cracked at over a dozen spots on each side. Here is the original post https://ls1tech.com/forums/cadillac-...ng-sh-t-2.html. Those were since replaced and the car sounds beautiful again. The lean bank 170 codes have since disappeared. Needless to say, a day after fixing this I all of a sudden get that damn po101 code again for my mass airflow. Some thoughts fellas. Need a new MAF sensor? Dirty air filter? Leaking volant hose? a retune? someone mentioned a dirty fuel filter?
Thanks

Ever since I cleared my po101 code a few days ago it hasnt come back on even under WOT. Most importantly though, I did my oil change today and was in for another surprise...FAAKKK. On my oil pan bolt (since its magnetic) was a 1 and 1/4 inch very tightly wound spring resembling a pen spring just much thiner and more tightly wound. Right away I called my tunner, being the nice guy that he is, he was able to tell me that it is most likely a valve seal spring and sure enough when I saw a vid of it on youtube BINGO. Wondering if anyone else has ever dealt or heard of this occuring with their LSx. My tuner told me that the car will be burning some extra oil due to it being pushed through to the lower block and sure enough it has. Burned about a quart during the 3-4K miles since last change answering my question from the last thread. How dangerous is this overall, as in, can I drive on it for a while till I get to it on the next oil change or should I pull the valve covers asap???

I already have heads and cam so this is just time and money down the drain...and from what I heard the heads dont have to come out for the fix just the valve covers and the dual valve spring wherever the seal is broken. I was hoping to spend the money on the labor getting my clutch in but once again it's postponed.
