Damn, that ain't good. Living life too fast?

Mustve been that crack that girl gave me... Here I thought I was gonna get a peice of ass

Blurr

that makes perfect sense, thanks. to be sure, the marks are to be used for reference AFTER installation to see if it skipped a tooth, right?

the prior installer must not have paid attention to the marks because when cyl #1 is @ TDC, both cam sprocket indicators point to their marks on the backing plate but the timing belt marks are nowhere to be seen.
in the below pic you'll see I put the crank pulley at zero and the cam sprockets line up with their corresponding backing plate notches. the rotor on the distributor is also pointing to the #1 cyl. I'm all set for disassembly, right?

Yeah, but even then once you have the new belt installed you can turn crank over a couple times to see if everything stays lined up. If the gears don't line back up, you'll know it's slipped.

Yep, tear 'er down bubba.

Here's a tip...
To get the cam gears off, if you don't have the SST, there are two things you can do. The easiest is to break them loose with the old belt still on and a breaker bar with a 19mm socket on the crank locked on against the bottom of the frame. The other way, although a little trickier, is to fit a 10mm socket on a long extension over one of the little backing plate bolts behind the cam gears. Use it as leverage against the gear to keep it from turning. That's the way I did it until I realized I could do it the first and easier way.

Remove the cam gears before you loosen the belt with an impact wrench. They bust RIGHT loose. Same goes for the crank bolt.

Blurr

well, i'm at the point to remove the cam sprockets and broke my cheapo Harbor Freight breaker bar doing so:



I think i'm going to try and make a tool similar to what i saw someone else here make (square tubing with a couple bolts at the end) to hold that sprocket in place. the wrench-on-the-crank-bolt-leveraged-on-the-frame-rail didn't work and neither did my impact wrench.

also, 5 of 6 fuel injector connector clips broke:



hopefully they'll stay put with a zip tie or something

You're going to need a torque wrench to put it all back together anyway so just go to Sears & pick one up. You can use it in place of a breaker bar.

OR, you could pick up an ELECTRIC impact wrench...

Blurr

not a whole lot of progress has been made due to the cam sprocket bolts refusing to cooperate. three more tools have been eaten up



i don't care so much about the breaker bar or the adapter but the ratchet was one of the first tools i have ever owned and i can only hope Sears will replace it with something identical.

one cool thing is a local Toyota repair shop loaned me a Matco cam sprocket holding tool. this thing is tough as nails and works great when leveraged against the upper pulley water inlet. I tried every method that other members have used to hold that pulley in place and they've failed, this thing is a life saver.

I recently had to take off my cam sprockets and had a tough time. I could not find a cam sprocket holder tool like the one you're now using. Rather, I ended up buying a $30 chain wrench. The chain wrench can damage the sprockets though, I had to put a peice of old timing belt and some rags between the sprocket and the pinch point of the chain wrench. I had to strap the chain wrench handle to the frame to hold it when torquing on the damn thing. I used an old torque wrench/breaker bar with a 1/2" drive. Finally, they broke loose. I didnt want to leave the timing belt on because it only had 5K miles and didnt want to take the chance that I'd damage it.

Blurr

Tool #5.



this guy helped me get off the passenger-side bolt then just couldn't hold together for the driver side. it slightly rounded the driver-side bolt when it broke, hopefully that won't get worse once i replace this socket and give it another go.

Blurr

Ok, the intake is out and the valley between the heads is about 1-2" deep in oil/coolant. Can this be indicative of a leak in the intake gasket and not the head. I couldn't find any indications of where the leak is coming from (HG or intake gasket) so I'm just throwing this question out there to see what you think.

jblake00

Not so much, there aren't any oil or coolant paths through the intake manifold. Once you have the heads off you can probably see where the head gasket failed.

justinking060310

I will say that it is not a probably - you will know where it leaked - lol - especially if you have that much under the intake.

justinking060310

i would double and triple check the heads/block for cracks - that isnt normal to have too much in there - mine had none

Blurr

there are coolant passages in the front and rear of the intake. you can see the front coolant passages in this pic, they go through the pinkish seals in the intake gasket.




i looked again and can't see any cracks in the head/block. there aren't any external coolant leaks so i'll have to hope the leak occurred on the inside part of the seal.

Chief_Yota

damn there is alot of oil coolant milkshake,and that intake look nasty,good luck dude.

Blurr

spent yesterday afternoon wrestling with the exhaust bolts, was unsuccessful. my problem is i had to chain together like 4 different extensions to reach the bolts from underneath the truck. they all bound up and none of the torque transferred to the bolt. hopefully some overnight Liquid Wrench soakage will help me out.

oh, here's what was drained out of the oil pan. yummy.

TNRabbit

I had to use 4 extensions as well; I ended up using an impact wrench to get mine off! After a liberal soaking of PB Blaster, of course.

Blurr

yeah i wanted to use my impact wrench too but as evidenced earlier in this thread, i broke my 1/2" to 3/8" adapter. i should pick one up today.

Rabbit, did you take your heads out with the exhaust manifolds and crossover still attached? without cutting my crossover or lifting the motor, i see no other way.

TNRabbit

Yes, I took them out in one piece. Don't make the mistake I made; I got up inside the engine bay & picked the whole mess up, then had nowhere to lay it while I climbed out. I ended up climbing out holding onto BOTH HEADS & CROSSOVER PIPE! Just about gave myself a dang hernia! What an idiot, huh?!?
