Why do Intake Valves get dirty?
Current engine design incorporates a technique called ‘Direct Injection’ where rather than mixing the fuel and air in the intake ports under low pressure the fuel is injected under high pressure into the chamber which mixed with the air as it enters. The advantages of this is better fuel economy, efficiency and performance. However, the disadvantage is that the fuel completely by-passing the intake ports therefore don’t clean the valves. When you take into consideration the inclusion of the EGR (Exhaust Gas Recirculation) system which increases the amount of unspent fuel, oil and other deposits entering the intake ports it’s no wonder the tops of the valves get dirty.
An vehicle that has carbon build-up on the valves may or may not experience engine management warnings and diagnostic codes. The first signs will likely be slight and gradual reduction in performance and mpg.
Cleaning your valves
There are numerous ways to clean or replace the Valves with varying prices.
The costliest option is to manually clean them. Most mechanics will recommend this – Why? Because they’ll earn well from the extensive hours it takes to complete the job. The price will be dependant on labour rates but for example for a V6 engine expect to pay anywhere for £200 – £400.
