Help For A Beginner In Engine Rebuld

[mmmk1985 0]

I am working in a project of rebuilding a xu10j2te 8v rgx turbo engine ( with a lemted budget)

After i disassembled the cylenderhead i noteced that i can move the pistons less than 0.5 mm side to side so i did a leak test and i found that half of the liquid gone after 3 hours

Note : Honing lines are very visable

Is that normal in cold or do i have to change the piston rings

You did a leak test in as you poured water into the cylinder and 50% of it leaked through after 3 hours?

 

I think you would have been better off with a cylinder leak test before you took the head off, using pressurized air.
