Upcoming Major Maintenance ???'s

[Mf Baker]

well, ive got a couple rounds of pretty nice work coming up here 4 the Runner. heres the list of things i am going to do so far in general:

1. change fuel injectors
2. replace valve cover gaskets
3. change timing belt


my questions are mostly about if i should do other things at the same time, and also about what all parts i should do when i do the t-belt.


1. fuel injectors and valve cover will likely happen at the same time. i have a 1st gen supercharger, so that needs to come off. -should i replace the valve cover gaskets and spark plug rings? or just tighten it down? it is leaking mildly. -should i replace the intake gaskets? - should i change the s/c oil while its off since its the first gen? so far on hand i have 6 refurb denso injectors and a new oem fuel filter. need to find oil and gaskets to do it all in one fell swoop.

2. for the timing belt, what all should i replace? obviously the belt itself, other belts, water pump and tensioner are being changed. i am wondering if i should do the cam seals, crank seal, thermostat, etc.

here is the kit im thinking of getting, its pricey but has got everything. should i go with a smaller kit if i dont really need to do all of those???

OEM Timing Belt Kit


on hand for this job so far i have the oem supercharger belt and a URD crank pulley(yup). i am going to use a URD tensioner as well, but they are out right now and its gonna be a couple weeks he said before i get it. what all else should i get???

should i do the oil pan gasket? should i do the starter while im under there doing everything? is there a better than oem belt that i should use??? (surprised URD doesnt offer one)



I know all the answers are contained somewhere on the site, but in searches i couldnt find the exact info i wanted, especially since i have the 1st gen s/c. Any info, suggestions, criticisms, or schooling welcome! Thanks all!

:hatsoff:

I'll leave the S/C up to others as well as replacing all the injectors. If you are going to keep the stock injectors, take them out, send them to witchhunter.com, and be done with it.

The link for the TB and other parts seems to be the best out there. If you have the funds, it would be the package I would choose first.

Try to find out if the leak is coming from the gasket themselves or possibly from one of the semi ciruclar or cam seal plugs. If it is the gasket, tighten the bolts down. If not, then removal and replace is the best option.

Id definantly replace all the gaskets that you have access to while your in there. As for the oil pan gasket and starter I say don't fix what ain't broke.

Depends ... how much do you want to mess with later? The more you do now the less you should have to pull it back apart for later. Budget doesn't always allow you to fix or update everything, but for me some things are just too cheap to not take care of while everything is apart. Personally I did the valve covers, including spark plug tubes, and sealing washers, along with new intake gaskets all at the same time.

thanks for the input all! im gonna do the intake and valve cover gaskets anyways i think. i will get the full oem timing kit and just sell off the extra parts afterwards like the oem tensioner and such.

as for the intake gaskets, can someone with a s/c tell me which ones i need? do i need this entire set of 4 with the s/c??? thanks in advance!

if you can, while your doing the timing belt go ahead and do the water pump too. if it starts leaking a week/month after you do the timing belt you will be kicking yourself in the @$$ because you have to take it apart all over again.

oh believe you me, i will be doing everything. belt, water pump, thermostat, cam seals, front main seal, URD crank pulley, URD tensioner, etc. :tongue:
