Sounds like a tractor

[cuprageoff]

hi guys please send your thoughts to me they will be appreciated.

my lc sounds like a tractor on startup and i would say gets a little less noisy when warm..
having looked into the matter on here im sort of pointed towards a manifold gasket. got someone to look at it and they couldnt identify a leak or loose bolt in that region. however could only get to 3 of the bolts. since then i have noticed my crankcase breather pipe located on right side of engine has a massive hole in it.... from research i have discovered this could severly damage engine/ loss of oil/ loss in power. could this be also causing the tank like sound...????
i have ordered a silicon replacement at just under £30 apparantly these are made from chocolate and are notorius for failing...
feedback will be much appreciated

Im putting my money on SAI / N112.

The breather pipe will make your car a bit jerky, but doestn make your car sound like a tractor. Check the whole PCV system btw, if one pipe is split, big chance the rest will be split as well (especially check under inlet manifold!)

my apologies what is SAI/N112. ???

Secondary air intake (SAI) believe its a pump not 100% though.

thanks well i have looked into it and its a minefield of info if your not a spanner man. i have got enough to check for now. alot is pointing to underneath the intake manifold so when its light ill have a look. when i first viewed the car it was noisy and there was a fan going on start up. still bought it though. it drives and boosts spot on. no warning light on dash etc.

Mine sounds like a tractor on cold mornings but I let it sit for 2 minutes then it returns to normal.

Thats the SAI. SAI injects extra air so the catalyst warms up faster, the bolts of the pump are known to fail, which lets the pump suck in extra air and more noise.

well thanks for the advice for the sai pump i will go and check when i can locate it.. just taken off the intake plastic manifold and from what i can see there isnt any obvious split hoses.. they are however looking tired. thanks so far... i will get to the bottom of this.
