Heavy breathing...not me, the fuel cap!

animatedsnail · Mar 9, 2008

Hi,

I've just read on the net to be aware of heavy breathing fuel caps on the 90TD.
Mines back in the garage after the fuel tank leaked!! but I was aware when I filed it up last after an empty tank that it gasped rather than breathed when I opened the filler cap! Is this normal, I just thought the landy was desperate for fuel!

Gasping is sign that the vent hole in the fillercap is blocked thus creating a vacuum. which leads to fuel starvation.

its the oil filler cap that shows how breathy your TD is. They all are, some much more than others. The pressure of the "breath" tends to push oil splashes up and then they run down the breather tube (the flexy hose) which meets a big hose and then the oil goes into the air filter mankying it all up big style.

If your's is breathy remove the filler cap carefully with the engine running and feel how much air rushes by yer hand. If your hand dislocates from your wrist, the skin falls off, the bone powders and your pulverised flesh splatters all over your bonnet - thats too much breath.

Remove the top of the air filter housing and check your air filter. If it's sopping black oil and crud encrusted either yer cars not been serviced since new or your engine's breathy.

Lots of folk fit an oil catch tank on the breather pipe. This catches the oil and saves yer filter.

My TD is breathy in a sexy kind of way.

A breathy engine is not a big deal unless its as bad as mentioned above. Just don't thrash it and service it regularly.

aye I knows that but who ever heard of TDs being known for having breathy fuel caps?? Just assumed he'd misread the interweb.

Thanks muddy,

It was the fuel cap I was asking about, and likewise I think they may have got wrong idea, that's why I posted, I thought I was missing something too obvious.

I will try the oil cap later, I'm awaiting the garage to fit the replacement fuel tank seeing the seams were leaking from about half way up the tank. They hadn't noticed due to the fact there was never any fuel in the tank when they sold it!

Thanks all
