#181 of 260 1993 Toyota Camry 2.2L Camshaft Question - Exhaust Camshaft service bolt?
Oct 22, 2009 (6:30 pm)
Just finished up installing my cylinder head and intake manifold as well as fuel rail on my 1993 Toyota Camry 2.2L. Installed the intake camshaft as well. I was ready to install the exhaust camshaft, but read online about the service bolt as well as in the manual, but the manual never stated why it was necessary. After further reading online it stated that the service bolt prevents the gears from unwinding and causing the cam to be out of time when removed. When I removed the camshafts I never placed a service bolt in the exhaust camshaft (should have now!). I never noticed the cam unwinding when I removed it from the cylinder head. I had the cylinder head and both cams to a machine shop for reconditioning. After carefully looking at the exhaust cam now I notice the do line up, but there is hole and something line a pin that are a off a bit out of alignment. Does the pin and hole have to line up? Looks like it would fit if the one gear was turned about 1/8 turn or so.
Wondering if anyone here has and answer to this.
Any suggestions would be greatly appreciated.

So you can see what was to happen on dis-assembly:
35. REMOVE CAMSHAFTS
NOTICE: Since the thrust clearance of the camshaft is
small, the camshaft must be kept level while it is being
removed. If the camshaft is not kept level, the portion of
the cylinder head receiving the shaft thrust may crack or
be damaged, causing the camshaft to seize or break. To
avoid this, the following steps should be carried out.
A. Remove exhaust camshaft
(a) Set the knock pin of the intake camshaft at 10–45°
BTDC of camshaft position.
HINT: The above angle allows No.2 and No.4 cylinder
cam lobes of the exhaust camshaft to push their valve
(b) Secure the exhaust camshaft sub gear to drive gear
with a service bolt.
Recommended service bolt:
Thread diameter6 mm
Thread pitch 1.0 mm
Bolt length 16–20 m m (0.63–0.79 in.)
HINT: When removing the camshaft, make sure that
the torsional spring force of the sub gear has been
eliminated by the above operation.

And on re-assembly:
B. Install exhaust camshaft
(a) Set the knock pin of the intake camshaft at 10–45°
BTDC of camshaft angle.
HINT: The above angle allows the No.2 and No.4
cylinder cam lobes of the exhaust camshaft to push
their valve lifters evenly.
(b) Apply MP grease to the thrust portion of the cam–
(c) Engage the exhaust camshaft gear to the intake cam–
shaft gear by matching the timing marks on each gear.
(d) Roll down the exhaust camshaft onto the bearing
journals while engaging gears with each other.
NOTICE: There are also assembly reference marks on
each gear as shown in the Illustration. Do not use these
5. CHECK AND ADJUST VALVE CLEARANCE
(See page EG1–12)
Turn the camshaft and position the cam lobe upward,
and check and adjust the valve clearance.
Valve clearance (Cold):
0.19 – 0.29 mm (0.007 – 0.011 In.)
0.28 – 0.38 mm (0.011 – 0.015 In.)
(e) Turn the intake camshaft clockwise or counterclockwise little
by little until the exhaust camshaft sits in
the bearing journals evenly without rocking the cam–
shaft on the bearing journals.
NOTICE: It is very important to replace the camshaft in
the bearing journals evenly while tightening bearing caps
in the subsequent steps.
(f) Install the bearing caps in their proper locations.
(g) Apply a light coat of engine oil on the threads and
under the heads of the bearing cap bolts.
(h) Install and uniformly tighten the 10 bearing cap bolts
in several passes, in the sequence shown.
Torque: 19 N–m (190 kgf–cm, 14 ft–lbf)
(i) Remove the service bolt (B).

#184 of 260 96 Camry timing belt change
Jul 30, 2010 (1:00 pm)
I have a 1996 toyota Camry LE that had the timing belt and water pump changed in 2004 at 55K miles The car now has 80K miles and Goodyear auto is telling me it needs to be replaced again because it's old and if it breaks will eat the engine. This doesn't sound right to me. Can anyone help me out with this Thanks!

Very low mileage vehicle.
I wouldn't be replacing it w/35K miles on the new belt.
I don't remember off the top of my head whether this is an interference engine or not (interference = if the timing belt breaks, the valves can get bent from the piston).
#186 of 260 Timing Belt vs More
Aug 25, 2010 (9:07 pm)
After starting my car, driving it approximately a mile..my 2001 LE started sounding like nuts and bolts were being tossed around, then started chugging along, soon sounded like the guts of it was going to drag on the ground. I pulled over. Parked and let it rest a few hours. This time when starting it, it still sounded nasty and ran the same. I was traveling from 2 states away so I had to chance it home (in the rain I might add). Approx 20 mins later, it died on the highway going 60mph. It was towed to a lot where the tow driver left my flashers on which I didn't realize until an hour later. The car won't totally start. I don't want to sound girlie (though thats what I am), but is the reason its not totally starting now, due to the lights that were left on and just needs a jump and new timing belt or could it be more? Also, I had a friend do a diagnostic on it. This is what it read:
P0115 Engine Coolant Temp Circuit Malfunction
P0340 Cam Shaft Position Sensor A-Bank 1 Circuit Malfunction
P0401 EGR Flow Insufficient
My friend noticed the coolant looks "dirty" and the level is at "just above the Low mark" and that my oil, (although I get timely changes) looked "not good" as well.
Another friend thats going to work on my car said after he puts in a new belt, the rest will probably fall into place (besides the fluids of course)
I haven't any family, am a single mom, and just have these couple friends to look to for automotive guidance but want to make sure I am doing what sounds right? I'm buying a new belt tomorrow and paying him 150-200.00 for his labor, Help?

I don't believe the timing belt is 'necessarily' your problem.
If the timing belt broke, the engine would stop immediately, it would not continue to run sluggishly.
I would suspect a more serious engine problem, if it was sounding like nuts and bolts clanging around. What is the mileage on this engine?
#188 of 260 2000 Camry LE maintanance
Sep 10, 2010 (10:18 am)
I recently bought my aunts 2000 Camry le 6 cyl. She has babied his car and kept all records. It runs great but people keep suggesting to do preventive maintenance on it, namely: replace spark plugs, wires etc.. replace timing belts and water pump etc.... This is all because it is over 100 k miles. Is this really necessary if the car runs good? How long will a timing belt last? What about spark plugs? and water pump? note that the belt does not interfere with anything, so if it breaks it just falls off. Anyone with info on how long these items last please email me or write at w_steuwehotmail.com THANKS

Well you can be proactive or reactive. If you are proactive you spend some money now and less later; if you are reactive, then you roll the dice regarding what ELSE is damaged when the part goes south, and also being stranded when it happens.
If you're quite sure none of these items have been attended to since year 2000, they are certainly all due. Pay now or pay more later, is how I see it.
Of course, if you plan to just ditch the car when something big breaks, then maybe just running 'er into the ground isn't a bad idea.

At first I was planning to just do it as preventive maintenance,but then the $2024 price tag to fix it all came up. I dont plan to run the car into the ground. But certainly 2000 dollars is too much to put into a 10 yr old car. What are the basics that i should definitely do? the problem is that it always comes up that while they are doing this they should go ahead and do that. Well thats what got me to the 2000 dollars.
