lots of smoke inside cab.

started the 90 up today to bring it over from my dad's and jesus there is a lot of smoke in the cab, i never noticed this last week and my pops has been driving it during the week, he noticed some smoke but not as much as today.

i've done a search and i'll check the obvious things

oil/fuel on exhaust
oil/fuel in bay
no cracks in the exhaust
make sure nothing is leaning on the exhaust etc

but i read someone posted saying to check a breather on the engine,whats breather is this and were am i going to find it ?

the smoke inside smells a bit like exhaust fumes so i spent the journey home hanging out the window, i bet i looked a right sight !

any help is appreciated guys

right the 1" hose coming out the top of the rocker cover breather, is prob hangin down the side of the engine bay , if its been breathing heavy / smoking , it stops the filter getting clogged with dirty oil , stick it back on the filter housing and see how it goes, if its already connected, check condition of filter , and if pipe is already fitted, check is ther oil in the filter housing

As 90 said - does your tail pipe end still under the landy ( as in not coming out the side ) ? as my old S2 didnt as it was rottrn and you could smell that all the time ..

.

cheers 90 thats a good place to start.

the tail piece sticks out by the rear wheel, i'm not sure if the smoke is coming from the rear of the cab or from under the passenger seat.more info tomorrow
cheers guys
