dont know whats wrong

[aharte]

i have a b16a2 eg6,when i start it when its cold it sounds awful,like a van or something for a few minutes,then it sounds ok when its warmed up,someone said the pistons could be bad?anyone know

[CivicSpoon]

throwing any check engine light codes? Is it your idle reving high? Saying that it sounds like a van doesn't really tell anyone anything, please be more specific.

[Greenblurr93]

it probably just needs a tune up.

[aharte]

no warning lights or high reving,its like a rattling noise,very loud,then it goes back to normal after few minutes,it just dosent sound good for that space of time

[aharte]

this noise comes from the engine/gearbox area

[Greenblurr93]

a rattleing??? chaeck your heat sheilds.

[aharte]

its definitly coming from inside,it sounds like a rattling noise,is this a bad sign,ive had other hondas and have never heard it before

[Greenblurr93]

coming from inside what? the engine? or cabin?? if its the engine its probably valve tick, just get your valve lash adjusted.

[aharte]

yes inside the engine,can you explain valve lash?

[Greenblurr93]

its been covered so im not going to write a novel, but basically its the gap between the cam lobe and the rocker arm.

[aharte]

is that the tappets

[Greenblurr93]

yes
