Sorry Nathan,
"split oil while topping up"?
I cant understand from language problems.

I think I will be able to renew this hose with better clamps,
the oil pressure switch O-ring and the oil thermostat O-ring without
dropping the motor.
I had my had (ups?) in there, its not big space, but I will try it.

Its amazing with these cars, if you start a project, in my case
header and exhaust renew, it seems it will never end :-)

Another question appeared when I removed the air filter housing.
There is a hose connected to the housing, going into the rear fenders wall.
What the hell is that for?


so far

I don't see how you could spill any oil in this area while adding oil to the oil tank. It does look like the crankcase breather hose or the thermostat o-ring is leaking. New clamps or a t-stat o-ring would be a start. The pressure swith looks dry, but while you are in there. Also, check the aluminum washers below the pressure switch. The large hose going from the air cleaner housing should go to the oil seperator. See pic below.

I cleaned the area and removed the ugly hose.
It was hard like stone, in first moment I
thought it was from steel inside.

I am very sure that this hose was one reason
for the oil in this area.

But I dont think its the major reason for the oil
on the left cylinder bank.

I will focus on the rockers next.
the search goes on...

thanks for the pic A930rocket, but the hose I mean
is a "fabric" one. In your pic its visible a little.
Its the hose near your upper left corner box
saying "crankcase breather".
I am sure, it is going in the fender wall.

Do you think you may have made a mess when refilling the oil tank ?

Are these o rings for the rocker arms generally available? I diodn't think they came with o - rings. Is this some type of mod ?

Thanks

Falk930

ah, ok thanks,
but no, I didnt...

@ theiceman
its a "standard" mod, those are rings from Porsche Motorsport,
but available as spare part. Nr: 911.099.103.52

Thanks I'm on it .. looks like a good mod to do if you are doing your valves anyway.

I remember now. That one goes from the air cleaner to the Carbon filter canister(?) above the thermostat in the right rear wheel well.

I pictured the hose, its the lower one:



and here the canister.
Is this neccessary?
What the hell is this thing doing?

I haven't used mine in years, so it can't be too bad...

I think it's a charcoal canister to filter fumes rather than let them go to the atmosphere.
