is this the same as a 7mge seal? as i was once told?
or is it the same as the 5m's?
can i just pop the crank pulley off to change it? or is more involved? (ie motor/crank out)

Probably the hardest part of this job is removing the crank-pulley bolt! You'll need plenty of leverage (unless you own a mighty rattle gun). The rest of the job is easy. Definitely need a gear puller for the crank-pulley. You might be lucky with the timing gear; sometimes they slide off the crank by hand. (No need to remove any other timing gear.)
Use a 7MGE seal. Check the fit of the seal on the timing gear. You might need to shorten the coil spring on the inside of the seal to ensure it will be oil tight.

yeah, timing pulley should come off reasonably by hand (wd or penetrating oil is helpful)
from memory, the crank pulley on the 6m needs something like 280-300Nm tourque on fastening!!

crikey, am i going to have to do all of this when i change my valve seals? i thought to get the cam covers off was abit simpler, remove the 3000pipe, remove the coil pack, remove the throttle linkage and then your there.

yes, you can do it the dodgy way like that, but chances are that if you have to replace the valve stems seals, then some of the valve guides have gone too
i had the VSS's replaced when i bought my 6M (40k kms ago), and i just did them again (guides mainly this time) a few months ago
had the guides been done when i bought the motor, i would not have to have spent the $500 to do them this time around
i strongly suggest doing the head properly
taking it off, completely stripping it, and rebuild
btw, we actually think it was the oil pump pulley seal that was leaking, not the crank pulley seal

actually the timing gear pulley was the hardest of the lot, we actually needed a puller to get it off, although it did only take 10 secs
the crank bolt was easy, just brace a breaker bar against the chassis, and crank the motor over once. easy
and the crank pulley actually can off by hand!! NO force was needed

If that's the case I would check the crank and pulley keyways to make sure they are not damaged.

thats not a dodgy way of doing it... thats exactly how youd do it if all you wanted to do was to replace the VSS's.
as for replacing the guides? youd be amazed at the durability of the toyota guides, and the acceptable wear limits the guides offer. eg: the 7m head im using has over 240000km on it, and the original guides have less than half the wear as speccd in the tolerances. the tolerances are VERY generous. unless something has gone rather astray in the engine, or if you had suspicions a guide was worn, id not bother.
