knocking noise..where should i start to look ?
i have posted about this before..but not in as much detail..
the 1st week of november i bought my 147 jtdm.
the weather was warm for the time of year(relevant later)
the car was fine and dandy. but i noticed a brake fluid leak under the car.
so the car went back to the garage for the leak to be sorted out.
by the time i got the car back, the weather had turned much colder.(week)
the leak had been fixed...... but i noticed that i now had a knocking noise.
it appears to be behind the drivers side of the dash or in the engine bay.
i can here it in the car, but have not heard it from outside.
also, it only does it when really really cold... after the car has warmed up a bit.. the noise goes away..
the noise is also there over bumps.... but , again, only when the engine is really cold..
the noise does not go up and down with the engine revs..
after speaking to the garage... they told me the leak was from the clutch.!!!!
is it possible that when they fixed the clutch... that they disturbed something???
the noise is 100% heat related..
warm car/long drive.......equals no noise
cold car/very short drive..... and i get the tapping.
the noise is not metallic.... i dont think it is the exhaust heat sheild.
i once had a car that had knocking arb's....but only when the engine was warm..i think the heat soak made the bush's expand
in this case, i reckon the cold is making something contract...
i have had a torch and looked around... but i really need some ideas?
i cant go to the garage and say..there is a knock but i dont know where from!!!!
