Sludge build up on a valve cover.

How to prevent sludge build up

In Oil Change by HomeTowne Auto Repair & Tire

Dirty oil — known as sludge — can solidify and block passages overtime.

It was found on the valve covers and solenoids of a 2012 Ford 150. 

The truck was brought in after its check engine light turned on. The customer also noticed an overall loss of power.

Lack of oil maintenance and combustion gasses that are traveling to oil can cause sludge to build up.

Deposits begin to stick to the walls of tiny passages, corners, and areas where there isn’t much oil flow. 

Proper oil maintenance and using higher quality oils can prevent sludge from building up.

We recommend having your oil changed every 5,000 miles, because we use full synthetic oil.
