Formula One teams moved to bypass FIA president Max Mosley on Friday after the governing body published a controversial 2010 entry list despite a standoff over next year's rules.
In an effort to remove what they see as the major obstacle to a solution, the teams association FOTA published a draft letter seeking the help of the International Automobile Federation (FIA)'s senate and world motor sport council.
Without an agreement, they warned that some teams would leave the sport.
"We respectfully seek the intervention of the World Council to facilitate solutions to the present situation," the letter said.
"We have attended numerous meetings with the FIA's representatives and have been unable to make any substantive progress.
"The entry list has been published with five established teams listed as conditional entries and Ferrari, Red Bull and Toro Rosso, who against their will, have been classified as unconditional entries," it added.
"All of these teams are united in their concerns about the present situation and are deeply worried about the crisis that Formula One now faces, a crisis that appears to be self generated.
"The teams wish to find a swift solution to the situation, but in case this cannot be done, they will reluctantly have to seek alternative solutions which protect them."
FOTA urged the world motor sport council members to support the teams in reaching a solution.
The FIA said earlier that McLaren, Brawn, Renault, BMW-Sauber and Toyota were only provisional entries and invited them to lift their conditions by next Friday after further discussions.

Formula One will have three news teams on the grid next year after Manor Grand Prix, Campos Grand Prix and Team US F1 were included in next year's line-up, which also includes all ten current teams although five of them are only provisional.
Despite the on-going wranglings over the introduction of a salary cap next year, all ten teams, including Ferrari, have been named on the 2010 entry list.
However, five teams - McLaren, Renault, Toyota, BMW Sauber and Brawn GP have only been named provisionally by the FIA.
All five teams now have a week to submit an unconditional entry in order to be fully included in the 2010 line-up.
The FIA statement said: "These five teams have submitted conditional entries.
Conditions
"The FIA has invited them to lift those conditions following further discussions to be concluded not later than close of business on Friday 19 June."
Champions Ferrari, the two Red Bull teams, Williams and Force India were deemed to be unconditional, while three new teams will line up in an expanded pack of 13.
Spain's Campos Grand Prix and the American-based duo of U.S. F1
and Manor Grand Prix operations were also included.
Ferrari's entry could now prompt a legal battle as they, along with the other seven members of the Formula One Teams' Association, initially submitted conditional entries.
However, Ferrari have already argued the FIA invalidated a contract agreed in 2005 as president Max Mosley failed to keep his side of the deal by not consulting with the teams over the rule changes.
The battle with Ferrari could run throughout the summer, but as far as McLaren, Renault, Toyota, BMW Sauber and Brawn GP are concerned, they now have seven days to decide which way to go.
If they fail to submit a conditional entry, the FIA will return to the pool of potential new entrants as they are determined to have a 26-car grid in place for next year.
At present, further due diligence is currently taking place on the other possible entries should further positions become available.
