How To Disassemble Your Car Engine

Before you start this project make sure you have cleared a shelf for engine parts and you have a clean box or metal can to hold all your assembly hardware. You do not want to loose all the bolts and small components.

  • Drain all fluids from the engine. Coolant and motor oil
  • Remove the intake and exhaust manifolds from the cylinder heads.
  • Remove drive belts, water pump and vibration damper.
  • You can Remove the ignition distributor if installed
  • Remove the rocker / valve covers
  • And also Remove the rocker arms, ball pivots, pushrods and lifters
  • Remove all the cylinder head bolts and put them is a safe place
  • Remove the cylinder heads – the head can be heavy, get a partner.
  • Put the cylinder head on a shelf for more work later
  • Check the cylinder walls and check for a ridge at the top of the cylinder
  • Ream the ridge off the cylinder with the ridge reamer
  • Study how the timing gears align then remove the timing gears.
  • Remove the camshaft front support bearing and the camshaft
  • Turn the motor upside down now if possible
  • Remove the engine oil pan.
  • Remove the oil pump and sump assembly
  • Check to see if all the connecting rod caps and main bearings caps have been numbered from the factory. If not – number them.
  • Study how the connecting rod caps align with the connecting rods
  • Remove ONE connecting rod and piston at a time and store in a safe place
  • Immediately reinstall the connecting rod cap on the connecting rod and torque
  • This procedure prevents damage.
  • Continue until all the pistons and connecting rods have been removed
  • Remove the main bearing caps one at a time starting from the ends and working towards the centre.
  • If you are doing an engine that has a transmission attached to it – leave the centre main bearing cap installed!
  • Clean and inspect all the engine parts for wear and damage.

Reassembly Of Your Engine

Once all of the parts have been inspected and cleaned be prepared to answer the following questions.

  1. Why is it necessary to deglaze the cylinders?
  2. How does the oil flow after it leaves the oil pump?
  3. What are the bolt torque specifications for your main bearings, connecting rod bearings and cylinder head bolts?
  4. Pinpoint and describe all the basic engine parts
  5. Connecting Rods
  6. Pistons
  7. Piston Pins
  8. Oil Pump
  9. Crankshaft
  10. Camshaft
  11. Timing Gears
  12. Cylinder Heads
  13. Intake and Exhaust Valves
  14. Combustion Chambers

If your engine is missing loads of different parts, heads up, since it can get pricey, and you will end up paying for quite a lot of restoration parts. Luckily for you, experts will always help you out, and you will not make a mistake with your purchase, as long as you ask right ahead.

 

3. Oil Quality Checking

While most engine oils are made to acceptable standards, their general and specific qualities can vary widely. Poor-quality engine oils are often put on the market due to ignorance or greed. Unfortunately, for the uninformed automobile owner, a high-quality engine oil and one of poor quality will look and feel the same.

Oil breaks down and loses its viscosity, as you probably know by now. You can end up with loads of different lubrication problems. Always remove the cap and look underneath to check out the oil. If you end up noticing dark black oil in your engine, you should get that changed soon.

The engine has always been the ultimate platform for identifying the required quality of its oil. Even as engine design has changed to meet performance, fuel efficiency and environmental standards, the engine continues to be the ultimate arbiter of oil quality.

4. Inspection Of Spark Plug & Turbocharger

park Plug & Turbocharger

A. Spark Plug 

A spark plug that has racked up miles should have a brownish or grayish color on the insulator and electrodes, but some gas additives have been known to turn fresh insulators blue, pink or ­purple.

Spark plugs are usually colored in dark brown. Any other color will mean that your engine is not in its proper state and that you should have it checked out. Wet plugs or oil even that is on top of your plugs will indicate several different issues.

  • HOT & COLD: Heat range is the speed at which a spark plug can transfer heat from the firing tip to the cylinder head water jacket and into the cooling system. If the heat range is too cold, the spark plug will be unable to properly self-clean by burning off carbon deposits. If a plug is too hot, it will cause pre-ignition problems.
  • Erosion: Every time a spark plug fires, the spark burns a few molecules of metal off the plug’s electrodes. Over time, this eats away the electrodes and rounds off their sharp edges. The erosion gradually increases the gap between the electrodes, which, in turn, increases the firing voltage required to generate a spark. Eventually the ignition system reaches a point where it fails to produce enough voltage and the plug misfires.
  • NOT A LEAK: Corona stains on the exposed ceramic body are normal. Corona stains are caused by the high amount of static electricity attracting particles of oil and dirt to the body of the plug — not by blow-by gases or thermal distress.

B. Turbocharger Onboard Inspection

Turbocharger Onboard Inspection

Turbos can also fail. Make sure that there are no broken shafts or damaged wheels. Always check this out by moving the shaft back and forth with your fingers. If it is more than 0.5 mm out of place, it will need some work and additional service.

Inspection of compressor side onboard which includes:

  • Dismantling of silencer, insert piece and compressor wheel.
  • Visual check and cleaning of insert piece and compressor wheel.
  • Dismantling of compressor side cover.
  • Inspect the locating bearing, locating ring and thrust ring.
  • Check the labyrinth sealing of the compressor for leakage.
  • Check the clearances and gaps on reassembly.
  • Restore the turbocharger for operation.

 

5. Oil Pressure Monitoring

The oil pressure can allow you to realize how other inner components will function and function in the future. Most engines and vehicles have experienced a indication of worn bearings, which may further alter the oil pressure. If you’re exploring this all on your own, then have a look at the strain by substituting the mill oil using a strain gauge.

If your stress ends up being anywhere from 60 to 80 psi to a slow bulge, this usually means it is good and healthy to go! Generally talking and appearing, you will likely spend the majority of your time repairing and assessing all the various types of oils.
