A WALKTHROUGH OF A JEEP ENGINE BEING BUILT AT GOLEN ENGINE

Machining and Pre-Assembly
Cleaning Process

Cleaning Process


We start off with a bare greasy block and put it into our electric oven where it bakes at 800 degrees for 5 hours. Once it comes out of the oven all the grease is turned to ash and it is ready for the blasting process. Our shot blaster shoots stainless steel shot at the block for 45 mins to get the cast iron back to new form.

Cylinder Boring

Cylinder Boring

We bore our blocks oversize using our Rottler bore mill.

Block Decking

Block Decking

Decking not only gives the block the proper surface finish to seal the head gasket but it also allows us to tighten the quench height.

Cylinder Honing

Cylinder Honing

Our new Sunnen SV-15 Hone keeps cylinders straight and perfectly round.

Line Honing

Line Honing

By line honing the blocks mainline we can blueprint the main bearing oil clearance to a perfect .002”.

Crankshaft Balancing

Crankshaft Balancing

We dynamically balance each crankshaft in our Hines Balancing machine for smooth engine operation and long life.

Connecting Rod Sizing

Connecting Rod Sizing

By honing the rod big and small ends we can blueprint the oil clearance and keep the housing bores straight and round.

Measuring Clearance

Measuring Clearance

We double check all housing bores to ensure they are all identical for proper bearing clearance

Seat and Guide Work

Seat and Guide Work

Our Sunnen VGS-20 seat and guide machine uses carbide cutters to lay in a perfect three angle performance valve job, this machine uses a pilot system to keep the valve job concentric to the valve guide.

Valve Cover Machining

Valve Cover Machining

We mill our aluminum valve cover so it is ready for our Golen Engine 4.6L Stroker Sticker.
