after having my memory jogged in jesters thread, i remember it would bea very good idea to take the t-vis plate off and give it a good cleaning and butterfly valve check. Is it possible to remove with the engine in the car?
i've done it with the engine in. its a pretty shit task but do-able. apretty fiddly and shit but yeah. replace the gaskets while your down there too! i can write a list of things that need doing but its pretty straight forward.
Not to sound stupid but although it is a pain in the ass, if you know where the nuts and bolts are it can be done easier than expected, also helps if you just happen to have an extra 3S-GE lying around to help get your bearings from too. taking off the hoses on the end of the intake and the throttle body makes things much easier and skinny arms are useful. other than that just a small ratchet and ring spanners and you'll be fine. Note* If a hose is in the way, remove it, after fiddling around it for half an hour you'll wish you had anyway, also check what hoses you can, nothing worse than finding a vacuum leak after you've just had a chance to check em. And Good Luck!
