97 Pontiac GTP L67 3800, M1 5w30 4.8k

[ATS-V]

800 miles into this interval plugs and wires were changes due to a miss in boost due to me checking a couple of plugs and fubaring a wire or two. Intake is starting to leak and GM tabs were added at the end of this interval. Oil was changed with GC and coolant level will be monitored closely, coolant level hasn't gone down a measureable amount.

Comments welcomed.

Fix the leak. Even though small, look how much your wear increased compared to the previous UOA.

If you don't fix the leak, consider frequent OCIs. I wouldn't go over 3k.

Hopefully the stop leak tablets plug up or slow down the leak.

Still excellent results for a car with the antifreeze leak.

Next analysis will tell the tale on if the GM seal tabs will plug this up for the time being. I was curious to see on how GC would do in the same situation since few variable change for me.

Keep in mind no visable drop in coolant was detected at the time same was pulled, very small leak.
