quick question:
can you remove the timing cover without removing the oil pan?
FSM says to remove the oil pan first. but do you have to?
i want to do an inspection.

Thanks

yah you can..

I have its not fun or easy, just make sure you get the 12mm bolt thats under the cam gear and the 4(i think theres 4) bolts that hold the oil pan to the cover

you might have to take the cam gear off....oh and plan on using rtv for the oil gasket, a lot of people use the TOYOTA FIPG its works well

replacing gaskets? chain? cover?
 
Bryan - I've done it with and without removing the oil pan, so the quick answer is NO you don't have to. But I think you'll be able to clean out whatever bits are probably in there and seal everything up better if you do remove it. If you don't remove it, you'll have to still unbolt most of the bolts in the pan and drop the front edge enough to get the timing cover in and out.
 
ok. thanks guys.
i am actually still trying to chase down my oiling issue from previous post.

checked the pressure with a gauge. light is correct. it is low until light goes out.

also swapped out the oil pressure bypass (spring and plunger) with a spare that i had. it was used but in better shape. no change.

my next suspects are either pick up tube seal or a seal between the block/timing cover and/or timing cover/oil pump. looks like i am going to drop the pan just to double check that there is nothing clogging the pickup tube as well.

thanks all.

I've done it both ways and it's MUCH easier to do with the pan off. You're not gonna be able to inspect the oil pickup by just pulling the timing cover anyway, you need to drop the pan. I really doubt the pickup is clogged, it's pretty big, almost 3" in diameter.

The Toyota FIPG is good stuff, I used Permatex "Right Stuff" when I did this job last weekend.

Have you checked your oil pump? Might be time for a new one?
 
thats the other thing i am going to check this weekend. got the gaskets from toyota to put it back on if its still good.

while im in there for the pickup tube, ill be inspecting rod bearings. can a 22re guru chime in and tell me which rod bearing wears the worst in these engines?

i'd rather not check them all if i dont have to.
 
ttt,

anybody know which rod bearing wears the most usually?
 
There's only 4, and 5 mains, just check them all.. As far as which rod wears the most... It depends on luck really. Usually the #1 main bearing will see slightly more wear due to the timing chain tension..... Good luck!
 
ok. thats good info. i probably should check them all, its just the weather here is going to be crappy all weekend, and the super bowl. i was hoping to get it done quickly.

thanks

??? Isn't it about the same time to check them all versus just one? Most of the work is getting in there to them.

While you are in there makes sure the oil lube holes are all clear.
 
Kind of.
I mean you have to pull one down at a time, making sure not to change the orientation of the rod cap to the rod. then pull the bearings out of the top and the bottom. then clean all the oil off really really really good. then slide the bearings back up top. then without distrupting the upper portion of the bearing slip in the bottom bearing and cap, with the plastigauge. then tighten everything down. then do it all over again to take it apart. and then check the clearence.
Then do it all over again putting it back together.
its just tedious and time consuming. especially laying on your back on the concrete. if it were out of the truck on a engine stand i would say screw it, check them all. but since its just such a pain i was hoping that someone could tell me that....oh number 3 rod bearing typically has the most wear, so just check that one. but i guess i got to do what i gotta do.

either way, its not happening this weekend. my driveway is covered in about an inch of water. soo......try again next weekend i guess.
