thinking about taking the engine apart
hey I have a 1990 legacy ls with 233000 miles on it and have thought about pulling the engine apart and cleaning it and putting new gaskets in it. would this be a good idea or give me anymore peformance. thanks

i dont leak oil but i think it burns oil. however it does not burn enough that it comes out of the exhaust. when oil gets low the engine starts making a knocking or ticking noise

Do a cylinder leakdown test to see where the oil is going. If its the valve seals, then you can reseal those, but rings get a lot more complicated if you haven't split a block or removed pistons before. I've described leakdown tests before, just search under my name. You have a 90, so I assume its N/A.
I'd say it's not worth it to tear it down, You dont lose coolant do you?

Kickin' it old-school.
yes it is a n/a unfortunitly, but no it does not leak coolant

It's not worth your time or money to rip an engine and replace all the seals unless your really pouring liquid form everywhere, or your rings or busted and burning oil like crazy.
Couple months ago i rebuilt a 90 N/A engine do to the keyway on the crankshaft being very damaged. This engine had 260,000+km and the internals were in very good shape for the years and km on it.
Just cause it's a old car with many miles, doesn't mean its falling apart inside.

i second that. i run Mobil 1 synthetic oil, and i change it every 5000km(3000miles) or 3 months, my oil is always clean, and that the way i like it.

Try replacing the PCV valve. Fixed my burning oil problem. It HAS to be a OEM pcv valve btw.
lol funny you guys say, EVERYTIME i get a oil change the oil is soooooooooo black and thick. Yet its always full. Car has 312,000km now equiv to like 200K+ miles. I am thinking to try synthetic. What usually tells me its time for a oil change or it's low is the lifters knocking from time to time.

Filters dont filter when they are new. I hope your 3k oil changes do not include filter changes or you might be doing more harm than good.
Besides, kevlar trash bags would be better than regular old plastic but better is not always "better"
The history of oil changes may surprise you. Don't you think its odd that 3k oil changes are no longer required by new cars? Older cars didnt require originally either.
Instead of spending the extra money on "feel good" oil why not send it off to BlackStone Labs and get a real idea of whats going on?

Ciper,
While I agree with you that as filter media fills, it will filter out finer particles.
However to say "large" holes is a real misnomer. Filters are designed to filter particles above a certain size, 10 micron, 20, etc. As the filter media fills, it's true you may stop smaller sized particles, but you do this at a reduced overall flowrate through the filter and typically create a higher differential pressure across the filter.
If the filter was properly designed, then the fact the smaller particles pass through the filter really don't matter because they should not cause any issues suspended in the oil circulating in the engine.

Large relatively speaking
Current engine designs aren't much different than ours and the change intervals are fairly long. Its not unheard of to go over 10k miles between changes on cars that have an automatic oil life calculator.
Either way why not spend the extra money on oil analysis rather than replacing it? You'd not only know when it was time to change but also have a trend that would show any other problems within the engine.
