Hissing Sound From Engine Bay

[Teerex]

Guys,

i own a 2003 model Honda Fit Aria sedan. Today morning when i popped its hood i noticed a sort of hissing sound coming from the engine bay. couldn't exactly locate where it comes from but sounded like its from intake manifold area ( i am not 100% sure though). More over when i step on gas the hissing increases and it give sort of a sound comes from a blow off valve. couldn't inspect the car further that time since i was rushed for some work. just got back home and planing to get it checked tomorrow morning.

what this hissing sound is likely to be?

could it be a leak from the gasket ?

your inputs are highly appreciated .

Cheers!

Vaccume (air) leak?

[Teerex]

yes. sounds like a vaccume leak mate. which parts need to be checked?

Snakes?

Snakes?

was going to say that. Just make sure there are no snakes in there!

ok jokes apart, Teerex for a start I would suggest just checking if any of the clapms and clips of the air intake have come undone.

Yuk, well hissing days are over for that reptile I guess.

if the hissing sound is from the tappet cover that could be a bit bad news. Remove the engine oil dipstik and race the engine. Remove the engine oil cap and do the same. If there is a spray of oil from either place then that could be signs of a compression leak.
