Markets The Dow Jones industrial average soared to a record in late trading, providing a final piece of evidence, some analysts said, that a long-awaited second phase of the bull market was under way. The Dow gained 14.79 points, to 1,292.62, exceeding the previous record of 1,287.20 set 14 months ago. Part of the day's gain came from technical factors, but it also reflected broad economic signs. Other market gauges also hit new records, and more shares rose than fell, for the 17th session in a row. Big Board volume fell back a bit, to 115.7 million shares. (Page D1.) Treasury bond prices rose sharply as traders and speculators were encouraged by reports that OPEC might cut prices and by a decline in short-term interest rates. (D17.)

A meter reader who walked into the White House says he ''just wanted to see how far I could get.'' And what he got, he decided after 15 minutes just below the Reagan family quarters and a week in a Washington jail, was ''an adventure - a real adventure.'' Robert Latta, a Denver Water Board employee on vacation to see the Presidential inauguration, says he did not know that wandering into the White House on one of the most important days of the Presidential calendar was illegal. But it was fun, he says, and he would do it again, ''only I wouldn't want to break the law.''

Ministers of the Organization of Petroleum Exporting Countries failed today to reach an agreement to overhaul the group's pricing system and planned to meet again on Wednesday. A committee of five oil ministers presented the group with a pricing proposal at the afternoon session here and the group planned to meet for a late evening session. But several ministers who gathered for it soon departed, saying that a number of members had been unable to conclude consultations with their governments. Venezuela's oil minister, Arturo Hernandez Grisanti, said differences remained ''in relation to the margin of differentials'' between OPEC's highest-priced crudes and lower- priced grades. He added, however, that ''there is a possibility to find an agreement.''

Japanese auto manufacturers help insure that the interior of a car is installed properly by taking off the doors, so they will not be in the way, and then putting them back on farther down the assembly line. American auto executives have resisted the technique, saying it is too hard to get the doors to fit right the second time. But there is no argument about doors here, at the former General Motors Corporation assembly plant now operated by New United Motor Manufacturing Inc., a 50-50 joint venture of G.M. and the Toyota Motor Corporation. On the Chevrolet Nova, the product of the new venture, the doors come off and go back on.

The Israeli convoys, sometimes 30 to 40 vehicles long, have been rumbling through the closed-off streets of this ancient port for days. The trucks carry the paraphernalia of occupation: steel cots, prefabricated sheds, even the huge concrete blocks set in the roads to stop suicide car-bombers. The convoys are closely guarded by tanks and by jittery foot soldiers happy to be leaving. The tension has been high in Sidon as the city awaits the departure of the Israeli Army. The Israeli withdrawal from this area, to lines farther south, is scheduled to be completed by Feb. 18. It is the first of three steps of what Israel has said will be the ending of its occupation of southern Lebanon.
