Thats a very good question, a timing belt is a dry belt. What that means is no oil should be in the general area. You have a couple of seals your camshaft oil seal and your crankshaft front oil seal. As long as both of those are not leaking then you will not leak oil in that general area.

How to mark camshaft on a 1zm-fe engine


Instructions
  1. Check Your Timing Belt
    • Check your owner's manual for the recommended mileage for replacing your timing belt. Replacement for a Toyota Camry is 60,000 miles for 1984 to 1997 models and 90,000 for 1998 to 2004 models.
    • 2Locate the timing belt and examine it for breaks, damage, fraying, worn spots or looseness.
    • 3
    • Inspect the belt for cracked or missing teeth. It's possible that foreign material collected between them.
    • 4Determine if there's damage on both sides of the timing belt. Single-side damage may be caused by the timing belt's guide.
    Remove Your Timing Belt
    • 5Unscrew the bolts to release the lower timing belt cover.
    • 6Disconnect the engine wire protector from the rear belt cover.
    • 7Remove the clamp holding the rear cover's engine wire protector clamp.
    • 8Take the bolts off the front cover and lift it from the engine.
    • 9Line up the crankshaft timing pulley groove with the oil pump by rotating the engine to the right.
    • 10Be sure the camshaft timing pulleys and rear belt covers line up. You may need to rotate the engine one full turn.
    • 11Undo the crankshaft pulley bolt and release the tensioner and dust boot.
    • 12Unscrew the bolts to release the lower timing belt cover.
    Install Your Timing Belt
    • 13Wipe off any oil or water on the pulleys.
    • 14Align the timing belt's front mark with that of the crankshaft timing pulley's mark and the timing belt's installation marks with those on the camshaft pulley.
    • 15Install the pulleys in this order: crankshaft, water pump, left camshaft, No. 2 idler, right camshaft and No. 1 idler.
    • 16Compress the tensioner until the pushrod's holes and housing align. Connect the dust boot to the tensioner then tauten the tensioner's bolts to 20 foot pounds (27 Nm).
    • 17Rotate the crankshaft to the right and line up its timing pulley groove with the oil pump. The camshaft timing marks and those on the rear timing belt cover should match up.
    • 18Put in the timing belt guide and secure the bolts to 21 foot pounds (28 Nm).
    • 19Secure the upper timing belt cover to 74 inch pounds (8 Nm).
    • 20Reinstall the engine wire protector and clamp to the timing belt cover. Replace the lower timing belt cover and secure the bolts to 74 inch pounds (8 Nm).
    • 21Reconnect any remaining items. Start the engine and check that the timing belt is functioning properly.

Hoow to set up the timing belt


What do you mean by drive belt. If your talking about the serpentine belt, it should have an auto tensioner. Same goes for the timing belt. There is no adjustment. If the belt is loose then it needs to be replaced.
Replacing timing belt,Sienna 1998:
1.Disconnect battery (-) cable and plastic wiper washer cowl assembly
2.Remove spark plugs and put all wirings,cables out of the way
3.Drain coolant (cold) and remove upper hose
4.remove front right tire and wheel plastic fender apron
5.jack up engine under oil pan with rubber,towel or wood slightly
6.remove right engine support rod and its bracket
7.remove all drive belts.Examine condition;Label if re-using
8.remove plastic upper timing belt cover & gasket
9.remove crankshaft pulley bolt-use the ff. methods: a.air impact wrench or Toyota Special service tool-best b.chain wrench on pulley then breaker bar/socket on bolt-good c.open fly wheel cover,jam screwdriver on gear teeth then unbolt-tough d.breaker bar/socket on bolt, jam bar tip on floor, lower car then "start" engine -smart
10.remove pulley by hand or use carefully 2 prybars then remove plastic lower T.B.coverand gasket
11.reinstall bolt and turn engine clockwise to align timing marks:one on each camshaft sprocket and one on the crankshaft sprocket
12.remove T.B. tensioner spring-2 bolts loosen alternately then keep upright
13.remove crankshaft sprocket guard then the sprocket, then the belt.
14.Examine belt condition for damage and correct cause of damage if any
15.remove idler T.B.pulleys & check for smooth operation/contamination/leak
16.check all oil seals, water pump leaks,etc
17.Check T.B.tensioner spring for oil leak and tension by pressing push rod against hard object-there should be no movement or leak
18.Compress push rod using vise, align rod hole with outer hole then insert small nail, pin or wire to keep it there then reinstall along with other parts removed
19.Install T.B.carefully.No twist, stretch,prying ,oil, moisture, bending

Do the timing belt cover on a 1996 camry have a seal or gasket that can leak oil, mine seems to be leaking for around that area. If so how to replace the seal/gasket?


The timing cover itself does not seal any oil from leaking. It is just a cover to prevent debris from getting into the timing belt and ruining it.

To find the oil leak you will need to remove the timing cover and inspect the seals behind the cam gear, crank gear, and oil pump drive gear, and the oil pump to block seal. The most common leaks on these are the cam gear.

1995 toyota camry leaking oil from behind the timing belt cover. Isn't this a major repair? Is the leak more than likely a camshaft seal?


If you haven't had the timing belt replace (60,000 miles is the suggested service intervale) this is an overlap of having the timing belt replaced.
If the timing belt is not due for replacement and its the cam shaft seal that is leaking. Its a pretty easy fix. Remove the top timing belt cover , and the crankshaft sensor wiring you may have to remove the front engine mount . Set #1 piston at TDC, Loosen tensioner w/ spring slip off belt. **Remove sprocket pull out old seal with a sharp pick. Greese and install new seal make sure its flush with its bore . Reistall sprocket. Slide belt over Cam sprocket tighten tensioner. Install cover and mount (if applicable) Check timing marks by turning crank two revolutions.
** If CamSprocket Bolt is difficult to remove then remove valve cover and use a 21mm wrench to hold the Camshaft while you crack off Cam Sprocket Bolt.
You will see the groves on the Camshaft where you can place a wrench to hold the shaft.
After you replaced the seal replace the valve cover gasket ONLY IF YOU HAD TO REMOVE THE COVER TO HOLD THE CAM WHILE REMOVING ITS BOLT.

This is about as major as it gets.

91 carolla water pump


No. You don't have to remove the timing belt to change the water pump. Check out the autozone.com website and register. It doesn't cost anything and you will have access to a repair manual for the vehicle. The steps for replacing the water pump can be found there. ( I checked) Hope this helps and best wishes.

Oil pump is leaking on 1996 toyota camry, 2.2 lt


Since your friend just replaced the timing belt, there wouldn't be a need to replace the oil pump O-ring and crankshaft seal unless they were leaking.

No, you cannot get to the oil pump unless the crankshaft, lower timing belt cover and belt are removed.

I have the same exact car with the same engine and just replaced the oil pump O-ring and crankshaft seal. I'm a good mechanic, but this is a tedious and time consuming job, but It can be done if you have good mechanic skills.


VERY IMPORTANT.
There is a big chance that the car's engine timing will be off, have someone who is knowledgeable to set the engine timing. If you don't and try to start the car, serious engine damage will probably occur.

ALSO IMPORTANT.
When you get the oil pump off removed all the old O-ring the new oil ring will not stay in place, I used petroleum jelly to keep the ring in place, it's perfectly safe and won't affect the operation of the oil pump.

If your not sure you can do the repair yourself, take it to a mechanic.
