One way of keeping car running costs down is very similar to your own health.You dont feel wel so you slow down maybe seek help,you know when you arent well.
Running a car requires you to gain some knowledge of a cars operation,the just get in start it up and away you go isn't a good method.daily tyre checks are a good start in the journey of self knowledge
a cars drivability or rather how bad it can get is diffrent among people.
does it start does it stop whatever but all engines will go one way ie down in performance or refuse to start there is no middle ground
remember solutions dont pop out of a scan tool or plug in and go,a code is a starting point.P0301 or cylinder 1 misfire could be either mechanical fuel or ignition. here the process starts in earnest
high pressure diesel pumps are the biggest cause of vehicles ending up in a state of nor worthy of fixing,though it is easy to condemn one without correct diagnosis.
Given the environment of the engine ie lots of reaching 85c and back to ambient it comes as no surprise that all the engines seal are given a punishing life.
Seals on the engine especially will fail giving rise to an air leak which can be very difficult to pin down.
We employ various methods to track them down.One of our main weapons is a smoke machine this produces smoke that is then pumped into the engines system.this can be EVAP or more usually the induction system
This test is a useful measure of a cylinders sealing ability.We use smoke in conjunction with this or pumping smoke in through the spark plug hole which then appears in the case of a leak either at the intake exhaust or in the crank case
