22re timing issues
#21
The '88 FSM shows the washer in the diagram on page EM-13. On page EM-17, for the 22re they call it the camshaft thrust plate and for the 22r there is a fuel pump drive cam.
My 85 & 86 22re's have the washer.
I'm having a similar issue on my 86, but I have the washer.

From: Nashville TN. I can help you if you're close BUT NOBODY CAN HELP YOU IF YOU DON'T FILL YOUR LOCATION IN!
finally!!
I'm dying here fellas, my RTE is running great at @30° BTDC runs, idles and drives ok, till you hit her hard(advance), driving around 4k rpms and she cuts back. I believe it's b/c the timing parameters are out.
I seem to be having some problems similar to you
see here: RTE will not idle and left over night seems to start w/ low compression and tick
i could use all the help I can, she's about one foot in the grave. I'm about to donate her for the $5 and sledge all you want, or to MythBusters to see what a vehicle looks like after a tank has run it over....
She has only minor surface rust so I'm gonna H8 to see her go...but she's already cost me in thousands in pain and suffering.
Oh yeah, and I've put tons of REs together but just can't seem to get this one.
all help will be mucho appreciated, THX
EDIT** whoops, I bought a cam gear partly b/c of what I herd here. Did you have to degree your cam? or did you just get it close and nail it?
How does this look?

I am dredging this thread up because I am having the exact same issue with my 88 4runner.
With the jumper in place I can either get 0 deg BTDC or 8 BTDC (spec is 5 deg BTDC). I have pulled the dizzy about a dozen times trying to offset it by less, but it really seems I am ½ a tooth off.
Any other ideas?
Background info:
When I jump the connector to set base ign timing the idle drops and ignition timing drops about 5 degrees.
The rig runs great other than that when I have it in the 0 deg setting it gives the classic symptoms of wanting a little more timing (duh I guess).
The rig runs amazing (in my driveway) when I have it in the 8 deg setting. I haven’t loaded up the engine to see if it pings.
It does have the spacer on the camshaft (as did the original OEM engine and the first rebuild engine).
I just finished putting the 22re in, the engine failed under warrantee, so it had to go back to the machine shop and redone.
I the dizzy is new with this engine because of wear on the gear.

This weekend I adjusted the valves, and took a look at crank to cam timing (hypothesis being the timing chain is off one tooth.) With the #1 cylinder at TDC on the compression stroke the cam was pointed just slightly to the pass side (11:45ish I would say), which seems to align with what everyone says it needs to be.

NOTE: I am running an extra 4ish deg of timing currently.
Thoughts?

I effectively am doing cave man timing now, it’s just these 22re’s are a touch fragile when it comes to head gaskets, so I am a bit gun shy. If this was a SBC I wouldn’t even be batting an eye.
I guess what I don’t know is where Toyota put the ignition timing in respect to maximum brake torque (MBT) for these trucks.
It’s pretty common with older EFI and carb systems (especially in trucks) to not be on the top of the MBT curve, but to be a degree or two retarded for safety margin. That means your total safety margin is more like 3-4 degrees (most engines don’t start pinging until a few degrees after MBT). This would ensure that if you are pulling baker grade in august or running from loyalist troops in the African desert loaded to the max GCWR the engine isn’t going to start pinging on you.
You guys doing it cave man style, how much initial and total timing are you running? When does the total timing come in?

I'd say by the photo the rotor's too far ahead. Pull the dizzy back out and reset it back a tooth, but make sure the notches on the shaft are lined up first. Just try and get the rotor at 10 o'clock.

UPDATE:
I think I figured out the issue, I put my factory Toyota dizzy back in this weekend (it was replaced due to timing gear wear) and I could time the truck perfectly. I believe the aftermarket replacement dizzy is made/machined wrong. I ordered up a new one and will see if I can find a replacement that doesn’t have this problem.

dont mean to dig up a old post
ive been havin same problem ive had 3 different motors in this truck and same thing not enough power . wheni got it it had 35s and 410s so i downgraded to 33s no difference i can haul a truck and trailor full and no difference in power , i even went down to a 30 and same thing still havin to criuse in 4th at 55-60 pedal to floor. ive put new tps , 02 sensor swapped out afms total ignition tune up any advise out there thanx in advance

Having the same problem
Went to take it to get inspected today. Never even made it. The truck had no power barely reved to 4k rpm so i turned around and went home. Pulled the valve cover and and the timing marks just didn't look right. I jumped it a tooth advanced and so the cam dowl is at 12 and the crank key way is at 12 just like it originally was. Threw the distributer in and back to square one. I can get the ign. timing down to about 5 degrees btdc with the distributor fully cranked. If i move it 1 tooth either way it wont start or runs like . I currently have it set at 10 and it runs great with no pinging. Anyway i've come to the conclusion that i am either missing a washer/spacer in between the cam sprocket and the distributor cam gear or i have the wrong distributor cam gear . Are they the same for a 22r and a 22re? I know 22r's have some type of spacer thing to drive the fuel pump. Is a 22re a bit longer to compensate for that? I've come up with conclusion because if i space the cam distributor gear out about 1/8 it lines the dist. rotor right up with the pick-up in the distributor. Any ideas? I was told the truck got a new motor about 25k miles ago. I dont know if it was rebuilt or a swap from a donor. When i got it the motor was smoked anyway

I have done that a couple of dozen times, going on either side by a tooth, but it needs to be 1/2 a tooth.
