A defect report is prepared.<\/p>\n<ol start=\"3\">\n<li><strong>Cleaning and Washing Components<\/strong><\/li>\n<\/ol>\n<p>All parts are cleaned using high-pressure washers or ultrasonic baths to remove carbon deposits, oil residue, and oxidation.<\/p>\n<ol start=\"4\">\n<li><strong>Machining<\/strong><\/li>\n<\/ol>\n<p>After diagnostics, machining processes are performed such as grinding, honing, boring, or crankshaft polishing.<\/p>\n<p>This restores correct geometry, clearances, and ensures proper piston group function.<\/p>\n<ol start=\"5\">\n<li><strong>Replacement or Restoration of Parts<\/strong><\/li>\n<\/ol>\n<p>At this stage, the following components are replaced:<\/p>\n<ul>\n<li>piston rings and bearings;<\/li>\n<li>gaskets, seals, and O-rings;<\/li>\n<li>valves, valve guides, and stem seals;<\/li>\n<li>and sometimes pistons, rods, the cylinder head, or the engine block.<\/li>\n<\/ul>\n<p>If a part can be repaired, techniques such as welding, spraying, chroming, or polishing are used.<\/p>\n<ol start=\"6\">\n<li><strong>Engine Assembly<\/strong><\/li>\n<\/ol>\n<p>After preparing all components, the engine is reassembled according to technical specifications.<\/p>\n<p>Torque wrenches are used to ensure proper tightening. All oil channels are cleaned for smooth lubrication flow.<\/p>\n<ol start=\"7\">\n<li><strong>Adjustment and Calibration<\/strong><\/li>\n<\/ol>\n<p>Valve clearances, timing phases, ignition angle, and shaft synchronization are adjusted. The fuel system, turbocharger, VVT system, compression, and balance are checked.<\/p>\n<ol start=\"8\">\n<li><strong>Installation, Start-Up, and Break-In<\/strong><\/li>\n<\/ol>\n<p>The rebuilt engine is reinstalled in the car. The first start-up and leak tests are performed, followed by a break-in period at moderate RPM (up to 1000 km). This allows the new components to settle and the system to stabilize.<\/p>\n<h2>Results of a Complete Engine Overhaul<\/h2>\n<p>After a high-quality overhaul, you get:<\/p>\n<ul>\n<li>Restored power and torque;<\/li>\n<li>Reduced fuel and oil consumption;<\/li>\n<li>Lower noise and vibration levels;<\/li>\n<li>Extended service life (up to 200,000\u2013300,000 km);<\/li>\n<li>Reliable and stable performance with proper maintenance.<\/li>\n<\/ul>\n<h2>Why You Should Trust Professionals with an Engine Overhaul<\/h2>\n<p>An engine overhaul is a precise engineering process where even the smallest error can lead to another costly repair.<\/p>\n<p>Entrust your engine to certified auto services that have:<\/p>\n<ul>\n<li>modern diagnostic equipment;<\/li>\n<li>experienced engine specialists;<\/li>\n<li>access to original spare parts;<\/li>\n<li>warranty for the performed work.<\/li>\n<\/ul>\n<h3>Conclusion<\/h3>\n<p>A complete <a href=\"\/en\/remont-dviguna\/\">engine overhaul<\/a> is a full renewal of your car\u2019s heart.
