I have a 1993 w250 with 172000 m. When I start it in the cold it leaks until it warms up. Should I rebuild it or run it? It runs great and am afraid to have it rebuilt. And it is expensive. But also think if I do not it will finally give out and in a bad spot on the road.

 

If it otherwise runs fine, just reseal it.

 

I have no expierence in resealing. do you have to R and I it or can you reseal it on the truck?

 

where is it leaking at on the pump?

 

center on the bottom. after the truck warms up to operating temp it stops.
