Oil pressure gauge line
Oil pressure gauge line
I have a 330GT 2+2, with a leak where the oil pressure gauge line connects to the fitting going into the block. I've gotten the fitting off, and am now debating whether to cut off the end of the hose and try to save it, or replace the entire hose. The hose seems pretty brittle. Any thoughts? Best place to get a replacement hose?
Thanks,
David

Hey Motob what are you guys using to seal the ends at Patrick Otis' shop? I'm pretty sure Francois uses the Permatex black goop (can't think of the exact name right now) for the oil lines as well. I know he uses if for the fuel lines and hasn't had any leaks. I went through a bear of time trying to seal my fuel lines and found you have to use the right sealant!

Hi Rudy,What were you sealing on the fuel lines? I have not heard of having to do this. Where was the leakage?
I had a horrible time sealing the fuel line between the electric pump and filter housing under the car. I eventually gave up and used a regular rubber hose, but later on I found that Francois uses a permatex gasket sealant that seems to work. I believe it's the "Aviation form-a-gasket no. 3 sealant." There is another product that is similar called "Super 300," so I'm not a hundred percent sure. These bottles tend to get the gooey stuff all over the labels, so it's hard to read.
Clamping these $$$ hoses is also another thing you have to be careful. Kerry uses a PVC pipe to hold the hose as the fitting is screwed in place, while Francois has an aluminum block machined to hold the different hose diameters much like a brake line tool.
Lots a little details and tricks to these cars!

Hi Tom,
I had the same leak in the same location watching it drip on the new Ansa muffler while running. My problem was the the copper sealing washers were so worn they would not seal anymore. Once I replaced those (from Newco), the leak was gone immediately. I now try not to re use any copper washers ever. I assume you had already replaced the copper washers? Or was it from some other place on the hose? There is also a great sealant sold by Wurth (German) called DP 300. It is made under license from Rolls Royce and is especially made for fuel leaks. It is a blue transparent high viscosity gel that works fabulous. I use it when all else fails but fortunately not to often.

My leak was not from the copper gaskets, but I replaced them every *&%# time I took that hose out! Pollard goes one step further by annealing the washers before installing them. It makes sense, as the stamping process to make the washer work hardens the copper. Francois never reuses copper washers. The washers get a groove from the fittings that doesn't come out no matter how much you heat them. On a critical fitting or a hard to reach place, it's always best to use new washers and anneal them to insure a leak free fit.

Personally, I have had great results with black (NAPA brand) RTV for sealing the oil lines and Permatex aircraft sealant for the fuel line. The latter is a tar like substance that never changes consistency. It stays syrupy all the time. If you get a drop on your flesh you'll have to live it till you naturally exfoliate. Nothing seems to wipe it away.
