Choose Your Automotive Engine Rebuild Help Topic Below
The usual reasons for an automotive engine rebuild are loss of compression; excessive oil consumption, or excessive oil clearances. So, before the engine is rebuilt it should be diagnosed; by performing a compression or leakdown test.
Oil consumption is the loss of motor oil; even though there are no significant external oil leaks. It can be caused by worn valve guides; dried valve guide seals, stuck oil control rings, or excessive cylinder to piston clearance.
The most common symptom of excessive oil clearances; is an awful knock coming from the engine. Low oil pressure is also a symptom of excessive oil clearances, but is less common.
Is it worth it to rebuild or repair my engine?
So, Most of the time it comes down to a personal choice. There are cases where it’s an easy decision. If the car is 20 years old with 300,000 miles on it and is falling apart at the seams; then it’s pretty obvious it makes no sense to fix it. If the car is 5 years old and in good shape it’s definitely worth fixing. Most of the cars that need engines fall somewhere in-between.
Our best advice is to have a full vehicle inspection done; before having the engine repaired; then consider the total projected cost of the engine plus any needed maintenance and repairs. Keep in mind that there is some uncertainty in buying a used car even if you have it inspected. Remember to include financing costs and full coverage insurance when thinking about a new car.
So my car will be like new, right?
Nope. The car is much more than just the engine. There’s steering, suspension, transmission, brakes, tires, axles, fuel injection, smog equipment, and a lot more. A car with a rebuilt engine will still run poorly with bad ignition wire; and still fail smog with a bad O2 sensor, and still overheat with a bad radiator.
What are the different ways of repairing the engine?
So, The least expensive is a ring and valve job. It includes removing the head and rebuilding it; removing the pistons and re-ringing them; honing the cylinder walls if needed and replacing the rod bearings. The philosophy is to repair the engine as needed.
You pay for what you get; so if your engine is less damaged then it costs less.
The next option is an in-house automotive engine rebuild.
So, This repair can fix pretty much any engine problem. Often this type of automotive engine rebuild starts out as a ring and valve job; where worn cylinder walls were found, requiring boring. It includes rebuilding the head; boring the cylinders oversized and new pistons; new timing components, decking the block, replacing the rod and main bearings; replacing the freeze plugs, and other repairs as necessary. The philosophy is to repair the engine as needed.
The third and most expensive way repair the engine is a rebuilt exchange.
