Here is a shot of a Dodge 4.7 dropped off for a complete engine rebuild
Your engine may look better or worse.
Before we disassemble this engine, we will give it a visual inspection, looking for obvious signs of damage, cracks, or cause of engine failure.
Plus we make sure all the components are there, sometimes clients bring their engine in pieces. Some even bring them in boxes and bags.
Nothing worse than hunting for small parts.
Any missing or broken parts need to be replaced. Luckily, we can source most any auto parts needed for your engine rebuild.
TEAR DOWN & INSPECTION
Here is where we tear into the engine and completely take it apart. Major problems are pretty obvious and now we can see if any problems exist internally.
Such as dropped seats, condition of the cylinders, any cracks on block or heads, any warping, or twisted components.
It's off to the Hot Tank to degrease so we can work with the parts.
CYLINDER WALL BORE
Hot Tanked and Clean, ready for block work.
Time to check the cylinder bore to see if they are round and true with good bore geometry and straightness.
Checking for pitting, scoring, scuffing, pin holes, etc. If the cylinders are not in good condition, they may need to be resleeved.
If everything looks good, we take measurements for proper application crosshatch angle, and move forward with boring the cylinders.
Now we can order the correct sizing for the Pistons and Rings.
First two cylinder walls are dull and black, not bored yet. Really in need of a refresh.
You can see the difference in the cylinder we bored. The surface finish is looking good.
These cylinders will have good ring seating and sealing and the pistons will have proper side clearances.
Time to put a nice crosshatch finish on the cylinders.
Pistons and Rings will fit properly after honing and retain the proper amount of oil for good lubrication.
You can see how remanufacturing and machining the engine components breathes new life into the engine.
Cylinder head repairs for optimum performance.
Basic Valve Job includes: Magnaflux for cracks, Grind valves, Cut 3 Angle Valve seats, Resurface, New valve stem seals, Clean, Paint, and Assemble.
After clean and disassemble, we inspect the valve seats and valve guides condition, making sure they are in good shape. Any missing or broken parts need to be replaced, at an extra cost. Resurfacing the head gives a nice flat surface, the gasket will have a good seal against the block now. Cutting the valve seats is next. We cut 3 angle.
The valves are checked for straightness and good condition, then we grind the valve surface. With both the seat and the valve reground, the mating surface will have an excellent match. Replacing items depends on the condition of your cylinder heads, some heads are prone to problems.
New valve stem seals are installed during final assembly. Then we put everything back together.
These heads are ready to bolt on the block.
