    This is a big job, especially if it is #1. Everything in the way will have to come off. Half the top end has to come out. How bad is this leak? You could be looking at a lot of work to do all of them. Basically the whole left side of the engine has to come off. I would say around 25 hours anyway!

    Hi, thank you heavyd for your advise, I just took a look at it again and gave it a power wash then discovered that leak is coming from nearby access pulley so opened the cover and found out that Oil seal on the accessories drive behind the pulley is broken so I guess that is where the leak is from. I will keep you posted once I replace the seal.

    Hopefully the acc/drive shaft is ok and it is just a seal.

    Hi, I replaced the oil seal on drive shaft behind the pulley and oil leak stopped but the motor had high pressure so its matter of time before it blow the seal again or something else. Some mechanic told that the bushings on shaft might needs replacing. I need any advise what would be the extreme damage motor if the bushings are bad. I have sunk lots of money on this this in the last year its 1997 freightliner N14 and 1.1m miles on it. Is it worth fixing or just replace it. Your advise will be gratly appreciated. Thank you

    has the motor ever been O/H'd? If not I'd run it on a dyno and see how the engine is doing internally with regards to blowby and compression. If the test comes back good then I'd have no problem fixing what needs to be fixed, but if the motor is getting tired than a O/H or even a complete factory Reman would probably be your best bet.

    Your at the time where you have to make a judgement call on if you should cut your losses and start completely over or continue to fix the existing engine.
