My 6m after it warms up I usually notice after I sit at a stoplight for awhile then hit the gas to go a buff of blue oil smoke comes out my 5m did this before and I'm guess its just valve guide seals.

My Question is do I really need to worry about his anytime soon or will I be ok? Other then that it runs really strong I can't wait to get it on the track and see what it will do.

Thanks

Its not too big of a deal, mine got to where it had so much carbon buildup it would ping under light throttle at highway speeds, plus I got annoyed at having to add oil every 700 miles. If you decide to leave it alone for now I woud recommend using some of the Toyota top engine cleaner to try and keep the carbon buildup down. It has a can of injector cleaner a spray that you clean the intake manifold and throttle body and a combustion chamber cleaner that get sucked in using a vacum line with the engine running.

How hard is it to just change the seals and can it be done with the head on?

Yes it can be done with the head on. It is a pretty big job I think 10-12hrs probably, and it helps if you have an air compressor to hold the valves in place while you have the springs off.

Well I don't want to wait until it is that bad, how long do I have.

It will basically last for awhile, nothing is going to "break", so to say.... But in the meantime, other things will start to happen.

If you are still on the platinum plugs (ie change them every 60K miles), plan on changing them sooner.... Your plugs will be SO FOULED UP w/ wet oil, that the plugs will start having trouble firing... Gas mileage will start to drop, because the motor is not making enough power & the ECU is trying to compensate.

Also what will be left of your valve stem seals will be so badly worn out, that in "some cases" the old seals are going to be a pain to try & remove (my old ones that I had swapped out last year (lasted about 140K miles) some of them were STUCK inside & they could not easily come out. Thus one of the reasons why my repair bill was slightly higher than the first time I had the seals done).

Finally, if you live in one of those emissions testing areas where they stick a probe up the tailpipe & they check your emissions at both cruising speed & idle, your results are going to be borderline passing... Not a good thing if it's really leaking oil down the valve stems/guides.

Things to think about.

you dont' need compressed air to hold in the valves...you can use a pice of 3/8" thick rope...and then turn the crank until it smashes the valves against the head.

I don't have to worry about emssions here yet. And if its like my older motor it was only leaking on the exhaust side so it never made it to the plugs and didn't affect the way it ran. The exhaust side usually go bad first because they run hotter.
