Engine Rebuilding And Repair


With so many working parts to a vehicles engine, things get complicated. Most mechanics and dealerships generally don't have the expertise. A malfunctioning engine requires proper care and/or rebuilding.

Our team will replace all basic pieces and parts including bearings, gaskets, o-rings, and belts. We’ll also service crankshafts, pistons, valves, and camshafts.

Should any of these items require replacement, Lou's Machine Shop, LLC will make sure that they get replaced with high-quality parts that are sure to last you a long time and save you money!

Cylinder Head Resurfacing/Rebuilding

o-slider1a - Build and Tune

The cylinder head is an essential part which is used to form the combustion chamber in each engine.

If your engine fails a compression test or is leaking pressure, your cylinder head may require rebuilding.

So why rebuild instead of purchase a new cylinder head?

Brand new cylinder heads could cost up to $1,000.

It is much more affordable to rebuild your cylinder head rather than buy a new one. We have the machinery and years of professional training to offer you a quality rebuild for a much lower cost.


Radiator Repair

A Guide to Car Radiator Repair - OBD Solaris

Common radiator problems include:





Failed Thermostat

Different problems will require different solutions but it's important you don't continue to drive with significant radiator issues. 

Down the line, a damaged radiator can lead to harmful engine damage which calls for a complete and costly replacement. Save yourself the money and have your radiator repaired before there's a more serious issue.


Engine Honing

Honing Aluminum Blocks - Engine Builder Magazine

Over time, cylinder walls wear down.

If not taken care of, an increase in friction between will lead to more damage that just builds up over time. We want a thin layer of oil to help lubricate between the piston rings and cylinder walls.

We'll use boring and cylinder honing tools to correctly shape the diameter, surface finish, position, and crosshairs of the cylinder walls to as perfect as possible.

Doing so will ensure proper lubrication and oil consumption to get your engine running right!


Valve Jobs 

Piston/ Valve Damage - EvolutionM - Mitsubishi Lancer and Lancer Evolution Community

Generally made from steel or other strong materials, valves are designed to control the intake of fluid or gas to and from combustion chambers.

Damaged valves will cause reduced engine power, idling issues, and backfiring.

At this point, a valve replacement or resurfacing job is necessary.

Helpful Tip: To help prevent future valve damage, ensure an efficient cooling system. This will help stop engine overheating. Also be sure to fill up your tank with quality fuel. Lower quality fuel may be cheaper, but it will cause more carbon build up on the valve seats.
