Thanks for the info..... sorry that something occured there.
That does not appear to be a peeling issue. Peeling has not been an issue with Jett's liner processing. I guess anything is possible. It is not likely going to flake. But you do not want to contiune running it like that either.
Looks like the engine ingested something. It "ate" something. More likely that chipped the liner and induced the score in the pistion. No way to tell what it was from the photos.
In any case, normally you just have to send the engine back to Jett Engineering and Dub corrects any issues. In your case, let me check with the "boss" first.
Please send an email with this information to
[email protected] along with the photos. We can work from there.
