Type IV rebuild / refresh thread. Nothing ground breaking., Changing cam in low mileage rebuit 1.8, making it a little hotter! Oh yea! Options

I popped the heads off in order to remove the broken exhaust studs (one per cylinder)

(I wrote broken head studs....I meant exhaust studs)

Stock camshaft has some strange wear patterns on it which might be part of the previous owner problems with the motor.


Cam will be a 9600 grind from Rabys old store

Intake planned is stock L-Jet, however I can be swayed to install Megasquirt (plenum or ITB) since I already have the Megasquirt.

Exhaust is older European Racing Header.

I ran the part numbers on the head and the cylinders, 1.8 parts.

Cylinders are in great shape, no pitting just some discoloration.

Stock camshaft looks odd, or at least to me.

The heads show no signs of cracks, I didn't have to do much to clean the springs and seat area, just wiped off the old oil and sprayed with hot water.

Pistons are in good shape, the one pictured has signs of something falling in there or is that detonation?

Combustion chamber has a few little divots just like the piston, very minor.
I think piston #4 had the most buildup on the top.

I still have a bunch more cleaning to do to the heads and case.
