  • connecting rod fitting/conversion
  • connecting rod bushing hydro bore honing
  • main housing and caps line boring
  • valve refacing
  • valve guide replace
  • valve seat ring insert
  • turbo blast degreasing
  • and oil seal build up

P13,500 Cost of parts to be bought includes:

Reasons why a Need for an Engine Overhaul

1.  Bluish white Smoke-this is sometimes called blue-gray-smoke.  It is a symptom that there is oil leakage and is being mixed in the combustion chamber.  Oil maybe passing through the valve, or through the head gasket.  It may also be through the worn piston rings or perforated sleeves.  The worst thing is the block has a crack but this is very rare. If this bluish white smoke appears it is necessary to have an overhaul.

What is to be done?
If you are sure of what the causes are especially if they are obvious it would be easier for you.  But if you are not sure you need the following to be done: 

  • valve replacement
  • valve seat replacement
  • valve guide replacement
  • piston ring replacement
  • gasket replacement, and
  • cylinder head resurface.

Hopefully, after administering all those parts replacements the issue should have been resolved.  If the issue remains you have the worst thing and that is an engine block replacement due to a crack.

It is, therefore, best if you bring your engine in a shop for overhaul let the engine block be inspected first to ensure you will not repeat the same task after everything has been done.

Possible Causes that Contributes to the Damages of Parts Mentioned Above

1. Oil Deficit-an often oil deficit in a long trip is definitely a cause to the damage of engine parts like block gasket, valves, valve seats, not so usual with valve guide or valve stem.
Lack of oil will cause engine overheating.

2.  Irregular or a Late Oil Change-this has something to do with oil viscosity.  If oil is already viscous before you change it adds to the high temperature of the engine.

3.  Lack of Coolant-this is why water as coolant is very important on every journey. Be sure to inspect your radiator if it has sufficient water. Lack of water causes engine overheating.

All of these oil deficit, irregular or a late oil change, and lack of coolant are causes of engine overheating that can melt the block gasket even the valves and valve seats.  It could even result in sleeve perforations and the worst thing the block cracking.

Why not attend to the symptoms and address it immediately than to wait and incur a four hundred times of expenses and much time spent.





  1. I’m about to do an engine overhaul on my 2005 Impreza Outback, so it’s great to see a simple breakdown of how much things will roughly cost! It might be expensive, but it will double the life of the engine and I love that little car, so it’s more than worth it in my eyes. Again, though, thank you for the helpful article!

    • Yes, once an engine is opened you have to fix everything.  If you need to replace the cylinders you have to than ignore and it will waste your time if it repeats the problem.

      If you are doing it by yourself you will have all the time to give the best for your car.

  2. When a car’s engine begins to sound like wired when it idles, while it is accelerating, or as it turns off, then you may need an engine overhaul. Even smoke bloat from the exhaust pipe, or if your car runs too hot, it could indicate serious engine damage. Bluish white smoke is the main reason for engine overhaul. Oil deficit in a long trip is definitely a cause to the damage of engine parts like block gasket, valves, valve seats, not so usual with valve guide or valve stem.
