When You Need to Rebuild Your Diesel Engine

The Diesel Engine is one of the finest marvels of engineering ever produced. It was engineered, patented, and perfected for mainstream applications by German inventor Rudolf Diesel. The theory was to create a higher compression engine that ran more efficiently by compressing the air tightly enough to ignite fuel. 

Today, the diesel engine is the most durable engine on the market. This is due to the high operating temperatures and pressures that a diesel engine must face. Gasoline engines may only reach temperatures and pressures half that of its sturdy diesel counterparts. For this reason, diesel engines are built to last twice as long as their high RPM cousins. 

When it is time to rebuild your diesel engine, you will need to find the best diesel engine repair Houston TX. Many of the final signs of severe diesel engine wear are obvious: blue engine smoke, white exhaust smoke, failed emissions, excessive oil consumption, metal shavings in oil, heavy engine knock. Once internal parts accumulate excessive wear, the diminished compression makes cold starts problematic. These problems diminish after the engine warms up, because the pistons expand significantly to compensate. 

The high operating temperatures of a properly running diesel engines comes treacherously close to melting aluminum pistons. If the oil cooling systems fail, your engine can melt down in a matter of seconds. While aluminum may be lighter than steel, steel pistons can be produced of equal weight by removing excess material. Many use new aftermarket engine parts with anodized coatings in the ring and crown when building a high boost engine. Applying Teflon-like anti-friction coatings to the piston skirts has become another favorite upgrade in custom diesel rebuilds. The anti-friction material acts as an additional safeguard against dry rubbing of metal materials in cold starts, extreme pressures, and intermittent oil pressure losses. 

There is a great deal involved in rebuilding a diesel engine. Even the most minor changes can create a world of problems after the build is complete. If the replacement pistons have a different bowl configuration than the originals, this alone may severely impact fuel economy, performance, or emissions. Unless the entire reworking of the engine is done by an expert, any slight modification to compression or pistons can drastically alter these three factors. There may be dozens of different pistons available for the same diesel engine. You have to replace factory parts by matching the correct serial numbers. 

Whenever you rebuild an engine, you are going to want to have it hot-tanked. This will remove any carbon build up and deposits. You are left with a stripped-clean factory-new looking engine block. After thorough inspections for cracks and defects, precision tools may used to re-bore the cylinders and insert new pistons. A specific type of lubricant is used to prevent the engine from seizing on a dry start. With all of these principles in mind, make sure you thoroughly discuss your goals and objectives with a reputable diesel engine rebuilder before you jump into a long-term investment.
