This will be my first OHC rebuild. I’ve worked on a G-15 and an R-16, but this will be my first U20.
The first step will be to peek under the valve cover and under the oil pan and see what the damage is. I have seen a picture of the cam and it does have some surface rust.
Smog equipment has been deleted and the fan clutch has seized. The car came with a new 4-blade fan and spacer in the trunk.
Radiator looks like it was recently redone.
