Bought a cheap borescope from Amazon. My intention is to confirm cylinder wall condition so I can rule out piston slap or not. Also use this chance to tighten my spark plugs to correct torque.
So, this is what I found for my 144k Theta II engine...
Can't see anything here as piston is close to TDC.
Honestly, got what I paid for, hard to do inspection when your tool is cheap. This scope does not bend well, compared to whatever car care channels on YouTube are using. The lens is too small to capture lights and I can see nothing on cylinder wall. Pretty disappointed to me.
After this I stick the scope in oil port and see if I can get a view under the cover.
One of the lobe that close to the timing side
Probably a lobe for cylinder 2 with valve bucket
Overall pistons have less deposit than I thought, but the concerns are piston 2 & 4 that has part of their edge shining, as well as the reflective cylinder walls. For cylinder walls, would it be this reflective when brand new? I'm worried if these are worn patches. Regarding pistons, not sure why the edges are shining. Ring wash? But oil level doesn't go down. Now more conflict evidence for me to sort out!
How would you rate the condition of this 4-banger under this mileage?
