Hi,

I bougth a used Rexton 290 with a MB OM602 5 cylinder engine, had to replace the belt because it broke and now I can't seem to get tension on it; what am I doing wrong?
Can someone send me the diagram? Previous owner had accident and the cover that goes on the top of the radiator is missing and no owners manual.
The engine also has a small oil leak coming from somwhere where the intake manifold connects with the head and from the blowoff valve from the turbo, are these leaks difficult to repair? Never worked on a MB engine before, appart from doing oil changes.
He was using 25W50 Texaco oil; in my previous diesel, I used 15W40 from Repsol[non synthetic], which one should I use on this engine?
If you want to can PM or send me an email to darkmonster620@gmail.com.
Many thanks,
Carlos
