Engine Repair — General Information
It is not always easy to determine what and where in the engine requires repair: too many factors need to be taken into account. High engine mileage is not always a prerequisite for repairs and vice versa - low mileage...

Compression pressure monitoring («compression»)
1. Compression will tell you about the condition of the pistons, rings, valves and head gasket: large leaks indicate wear or damage to these parts. Note: When measuring compression, the engine must be fully warmed up...

Engine Removal — Methods and Safety
If you decide to remove the engine for repair, some preparations must be made. The choice of the place where the work will be carried out is extremely important to ensure space for servicing and storing spare parts. It...

Engine — removal and installation
Note: Read the entire section first. The engine and gearbox are removed as an assembly. The gearbox is removed outside the vehicle. Removal 1. On fuel injected models, relieve the fuel pressure in the system ( see...

Alternative Engine Rebuilding
During the repair process, you may make quite a number of alternative decisions. The decision to replace the block, piston/connecting rod assembly, crankshaft depends on many factors, the first of which is the condition...

Engine Repair — Disassembly Sequence
1. Installing the engine on a stand significantly simplifies the assembly and disassembly processes. Before installing the engine on the stand, remove the flywheel and rear oil seal. 2. If there is no stand, disassembly...

Cylinder head — disassembly
1. Disassembly of the head begins with the removal of the intake and exhaust valves and the corresponding parts. To do this, remove the additional valves (if installed), rocker arm axle assembly and camshaft. For more...

Cylinder head — cleaning and inspection
When cleaning the cylinder head and valve train parts, carefully inspect them to decide on the scope of service work. Note: If the engine has been overheated, there is a high probability of warping the head (see step...

Valves — Maintenance
Since for the production of this type of work (repair of valves, seats and guides) a set of skills and special tools are required - it is better to contact professionals.

Cylinder head — assembly
1. Make sure all parts needed for assembly are present and clean. 2. If the valves are already installed, skip to step 8. 3. Install the spring seats on the guide, install new seals on each valve guide. Keep in mind...

Piston/Connecting Rod — Removal
Note: Before removing the piston/connecting rod assembly, remove the cylinder head and oil pan. Refer to Part A of Chapter 2 for the necessary information. 1. Use your finger to check for a protrusion in the stop zone...

Crankshaft — dismantling
Note: The crankshaft can only be removed from the engine outside the vehicle. The flywheel, rear oil seal housing, crankshaft pulley, drive belt and gear, pipe, piston group must also be removed. 1. Before removing the...

Engine Block — Cleaning
Attention: if the block plugs fall into the cooling jacket, it will be almost impossible to remove them. 1. Remove all protruding parts from the block. 2. Drill small holes in the center of the plug and use an inertia...

Engine Block — Inspection
1. Before starting the inspection, perform the work in paragraph 14. 2. Determine the presence of cracks, corrosion, deposits. Inspect the condition of the threads. If the detected defects cannot be repaired. Replace...

Cylinder wall honing
1. Honing of the walls creates good conditions for the operation of piston rings, therefore we recommend this type of treatment. 2. Install the main bearing caps and tighten them to specification. 3. The most common...

Piston/Connecting Rod — Inspection
1. Before inspection, wash the parts and remove the piston rings. Note: Use new rings for assembly. 2. When removing the rings, try not to damage the piston surfaces. 3. Remove any carbon deposits from the piston head....

Crankshaft — inspection
1. Wash and dry the crankshaft. Clean the oil passage holes with a stiff brush and wash them with solvent. Fig. 18.1 Clean the oil passages with a wire brush and rinse them 2. Check the main and connecting rod journals...

Main and connecting rod bearings — inspection and rejection
1. Even if you decide to replace the bearings with new ones, the old bearings should be subjected to serious analysis, as they can provide a lot of information about the condition of the engine. Fig. 19.1 Typical...

Engine Repair — Assembly Sequence
1. Before you begin assembling the engine, make sure you have all the necessary parts, gaskets, seals and the following tools. set of universal keys 12.7mm square drive ratchet ring mandrel ring puller vibration damper...

Piston rings — installation
1. Before installing the rings, check the lateral clearances in the ring/piston groove pair (see item 17) 2. The method for measuring the gaps in the ring lock is described below. 3. Insert the ring into the cylinder...

Crankshaft — installation and checking of bearing clearance
1. Installing the shaft is the first step in assembling the engine. Make sure the block and shaft are clean. 2. Place the block with the crankshaft bed facing up. 3. Remove the main bearing caps and place them side by...

Installing the rear oil seal
1. Before installing the rear oil seal, make sure that the crankshaft installation operations are completed. 2. Check the contact surface of the shaft journal again for scratches and burrs that could damage the sealing...

Piston/Connecting Rod — Installing and Checking the Clearance in the Connecting Rod Bearing
1. Before installing the piston group, thoroughly clean the cylinder walls, make sure there is a lead-in chamfer at the top of the cylinder. In engines with individual main bearing caps with an oil bridge, first install...

First engine start after repair
1. After installing the engine on the vehicle, fill it with oil and coolant. 2. With the ignition system turned off and the spark plugs removed ( see section 3 ) crank the engine until oil pressure appears in the...
