MS381 Scorching!

[upsideofdown85]

Hi all,
First time poster, long time stalker here.
I've got 381 I purchased second hand thinking it was a great condition saw. It is. Aesthetically. But after a trip to my local Stihl dealer after it stopped firing up after i got her home, I've found out that Internally, she has a scoring marks up and down the piston and cylinder.
My question you all is are aftermarket replacements an option or should I continue saving and searching for OEM piston and cylinder replacement parts?
I only ask this as I'm already $800 deep and wondering if I should keep travelling the path or turn around $$ wise.
Would greatly appreciate any feedback.
Thanks all in advance.
Also, I'm in Western Australia.

Remove the muffler and shoot a couple pics of the piston with the score marks

Better pics near the rings, please. It appears you need to get in there.

That's a giant exhaust port.

Find out why it scored, fix, go oem.

As above, first thing to do is work out if an air leak caused the damage (vac/pressure test before pulling anything apart). After that pull the cylinder & if you're lucky you may find the cylinder is salvageable & you can get away with just replacing the piston & ring
