Gasket replacing, how hard is it? Options

[Soulend]

I have a 3SGTE sitting in my garage that I've torn down enough to get the Turbo off so I can get it rebuilt. but since it's not in my car yet... I have been throwing back and forth the Idea of replacing the seals and gaskets... but I'm new at working on cars...

The engine is a used one with around 35-55K miles on it, and I have a strong feeling that it wasn't babied when it was used. my friend keeps telling me "you have it out you might as well" and my Father keeps saying "don't go to deep with taking the engine apart you could make a mistake and have to pay much more to fix it..." both my friend, and my dad have and do work on cars regularly. my dad really doesn't want to mess with the Celica engine because its Japanese, and he doesn't know Japanese cars. that and I think secretly he wants me to do the work to learn.

anyway, how much work would I have to put in to redo the seals and gaskets on the engine?

do you suggest that I do the replacement or just skip it and go on?


thanks for the help,

Kevin
