How to fix light scratch in cylinder wall.
Mkii 90 99 na turbo.
Btw i don t care who you are what i said is fact provided that in the verticle scratches they are less than the surface of the cylinder wall and not raised up into the cylinder inside diameter at all.
Meaning the scratch is not raised.
Originally posted by lostforawhile that sounds right the 220 would leave deeper scratches and better hone marks to break in the rings i could see using 400 if you had to take apart an engine with low miles where the rings were already seated did you use ported pistons.

Guys there is a tiny scratch in my truck s engine.
What options would i have to repair a scratched cylinder wall.
Only problem is burning alot of oil especially at start up and notices blue smoke between gears.
Bolt it back up and call it good.
Just throw a whole new set on.
I bet if you take it to the machine shop they ll tell you to properly fix it they will have to bore all 8 cylinders turn the crank hot tank new cam bearings and before you know it they ll have the tab up to a 1000 bucks.

It s a decent scratch or maybe even considered a light gouge.
I can barely feel it but it s enough to worry me.
Or should i just do a light ball hone and install the piston anyway.
If your cylinder walls turn out to be good you could just rering it and throw it together with new bearings and gaskets.
If they don t end up being good well then atleast you can weigh the costs of having a machine shop rebuild it or possibly find a used short long block in good condition.
If the motors out of the car just run a hone through it.
