Engine Hissing

[AlexMozza]

my engine seems to hiss, a little but like a snake in rhythm with the engine. as in one hiss per cycle :O
ill try and get a video for you guys. i think it may be a vacuum hose or breather hose my have a rip/tare in it.

Any ideas - the noise speeds up with higher revving :O

Check the breather pipe that comes out of the block at the front of the engine,they do split with age.

Is it the Golf Mk3 version with the steam engine?

Sounds about right  

My 8v also does this, and I have a re con engine with only a 1000 miles on it. Is yours an AGG? My old ADY didnt do it.

Maybe a vacuum leak somewhere? Try and spot whereabout the hissing is from, maybe one of the spark plug bores if it's done on a cycle

lol, yeah, its the George Stephenson version :O
Well it looks like the breather pipe coming out the block does not quite fit, looks like there been a bodge job done...just uploading the clip now :O#

Mine is 2E i think

Yeh its probably split where it goes into the block and been taped up,is the green horse shoe clip still holding it in?,if the hose is split then you can still et these from the dealer,part number is on the underneath of the hose
