oil line & tank cleanup?
Getting everything ready for my new motor from the good Doctor Timmins. How much effort should I put into cleaning out the oil tank and lines? Remove and take somewhere for a kerosene bath, just blow the lines out with air or leave as is?
Front trombone worked fine, got hot, with my 3.0L. Does crud build up in these lines?

The lines and tank were exceptionally clean on my car when I removed them last winter. My car has 66K miles on it, so it might not be a good guinea pig.
The tank only had a slight film of what looked like varnish on the inside. A rinse with brake parts cleaner washed it out just fine. I'm sure kerosene would do the same. I also removed the fender thermostat lines and cleaned off all the crud that was put on there from the factory. A look inside these lines showed no signs of sludge/crud buildup either. So, if a visual inspection of your lines and tank doesn't reveal anything, there's probably no reason to think there's some sort of buildup in there.

One exception. If there was internal damage to an engine, then all oil lines and coolers must be cleaned. Professionally, probably. I think our beloved Tyson Schmidt had the pleasure of rebuilding a 911 engine twice while learning this lesson. Bits of metal will be in those oil passages if the engine was damaged.
If not, then just inspect and reinstall.

If you are worried about it, take them to a radiator shop and get them cleaned out. They can do oil coolers, tanks and lines and its worth the time and trouble if you are not sure of their condition.
