due to the snow i've not been able to drive my car for a whole week

as the roads seems better i tried it today, and the battery was flat so i had to charge the battery,
anyway after charging it i started the engine with the bonnet up!
oh boy the engine was so damn loud,.
i don't remember it being that loud ever.

the car is 8 years old. and i am the only owner since new (bugeye wrx)
its due for a service this month,
but is it just old aged engine or anything else?

 

Paranoia probably. Does it quieten down when warmed through?

Engines will be louder in cold weather on start-up due to oil being really thick and flowing slowly, etc...

 

Takes longer for thick oil to circulate, some Scoobys (?) have hydraulic "lifters" so the valve-train will be noisy till the pressure builds.

HTH

dunx

P.S. Old tired oil won't help either, mine's due & MOT !
