I recently found a oil leak on my 98 jetta. Its. Coming from the oil cooler gasket. Is that a common thing for the car to do? And what should I do I the mean time to prevent the engine from going on me? I check the oil before I leave anywhere.

The same rule applies. try tightening the filter flange a little. if this does not work, again, the gasket will need replacement. It should be around a 13 millimeter spanner and you might need to work from above and below the car. First check that the leak is not perhaps coming from the oil filter itself and giving the appearance of being the flange. Both a loose or an overtightened filter can leak and the filter may have been installed with a dry seal, making it distort.

Just Had the problem with My 1999 Jetta with a 2.0 gas engine. What happens is the oil cooler gasket gets old and brittle because it is not usually replaced unless it's leaking.
The only fix is to replace the gasket. A little tough to get at but fairly easy to do. you can leave the oil cooler hoses on as the cooler will easily slide down and off with plenty of room to move it around and replace the gasket.
