[urq] Damaged cylinder walls caused by sand?

[Maurits Jonkergouw]

Thanks guys for the quick replies.

After reading all your responses, I feel the need to be a little more specific...

First of all, there is nothing wrong with the new rebuilt engine (as it's not running
yet), it was my old 300K KM engine which had been opened up and damaged by possibly sand
and the very reason for the rebuilt in the first place.

And yes, I did use the same PiperCross air filter for over 8+ years and cleaned it only
twice if I remember correctly, but I'm 100% sure I never soaked it with oil after I washed
it out, so I guess it must have been less effective each year without the proper
maintenance... my bad, very bad...

Summary:

My old 300K engine showed signs of damage by what's the rebuilder says, 'could be' sand;

The 0 KM rebuilt engine will be dropped in the car this month, and after reading your
reply, let's hope they DID properly cleaned out all the sand after blasting...

BTW, here are some pics:
