what were the symptoms of installing your timing gears one tooth off?
what was the vacuum before and after fixing the problem?
how did it start? idle? power?
im starting to question myself in my cam install.....
can someone point me to the thread where this happened to atljar? i searched to no avail.

thanks.....
Jesse

 

Here is the thread.

that is the thread about a broken crank bolt....
thanks for trying though.

Always good to be known for installs gone bad, lol.

I had it installed retarded one tooth. Its easier to do than you would think. I swore i had it lined up correctly, but sure enough once the timing cover came off it was wrong.

Car started very easily.

4.33 gears and the tires wouldnt turn over even if i dropped the clutch in 1st gear. NO power. Ran a 13.98 at 98mph with the cam off. Had been going 103-104mph before the cam swap.

Vaccuum was 4.5 inches before i swapped intake gasket (part of trouble shooting i went though). That jumped it up to 7.5 or 8 inches. Once i fixed the cam it pulls 9.5-10 iches. Still a little low, but i think i have lots of carbon build up from when the cam was installed wrong that i need to clean out.

Idle was rough, but not really horrible. I just figured it idled like that because of the size of the cam. Once i corrected it it still loped, but it was a smoother lope if that makes sense.


It really isnt that hard to go back in and check to see where the cam is. Took me about 4 hours from start to finish. Radiator, fans, water pump, opti, timing cover. Mark your rocker nuts with a permanent marker. That way you dont have to reset all your valve lashes again.

another possibility is that the cam was ground incorrectly (rare but it happens). If you get in there and dont see a probelm, put a degree wheel on it. Also, did you use the correct keyways for the timing chain?

I will try to find my old post too, give me a min or two.

 

Here is the post. Lots of good info in there.

i used the cloyes, it has 3 keyholes, i used the one that lined up the rectangle one. the others wouldnt fit on the key hole. the dot was slightly off at around 1130 when it should have been at the 1200. but i know for sure it was at #1 tdc because the heads were off.
my car has great low end torque (better than stock) when cruising in OD with the torque converter locked at 2400rpm.

it has decent top end. but it should have lots more.
i only gained 23mph in the last half of the quarter mile.

its starts easily, idles decent, revs smooth, only weird thing it does is sometimes backfire when i left off during a WOT blast above 5500rpm. other than that it drives good.

just looking for some suggestions.

atljar, dont feel bad, i dropped a valve (that how i got my heads ported ) broke a bolt in my cam and probably many more to come

 

Wrong keyway

You needed to use the cirle and the square with the circle top. Check out the box that my friend used to make fun of me with, lol. You need to use the middle setting.

Also, now that you mention it. My car would backfire through the intake when the cam was off.

Other thing. Dot to Dot should be #6 TDC, not #1. The cam dowel pin should be in the 3 oclock position when dot to dot.

 

That picture is the funniest thing I have seen all night.

 

man i used the same one you did the square one.

how did you get the middle one to fit on the cranks keyway?

i know what ill be doing tommorow

thanks for helping me

I actually used the right key way, but didnt have the dots lined up correctly. The picture was just a stupid joke he was playing on me, lol.

Anyways, it was a tight fit, but it went on. I used a big socket, that fit over the crank, but hit the gear, and tapped it on.

You want to use the middle keyway setting, and then the circle dot on the cam should line up perfectly with the cirle dot on the crank gear. once again, the cam dowel pin should be EXACTLY at 3 oclock. The crank keyway should be about 1 or 2 oclcok roughly. Good luck, and let me know how it runs after she gets fixed

 

i used the square hole but the dot was off a little, but i left the pistons 1 and 6 at TDC.

this is where i think i messed up:
i put the dowel pin on the 0900 position and the cam gear was in the 12 position, thats how i lined it up, so i could have very easily been off one tooth either way.

i put it in once and double checked, then a week went by before i finished the install, i removed the cam to lube it up again, and i cant remember double checking it before i put the cover on ?????

if my opti was dying, it would feel right in the upper rpm's? like stumbling etc?

thanks

what kinda trap speed should i expect? car weighs 3540 with me in it. i race at 2500 density altitude. i was thinkin at least 110 conservatively.....what do you think? i know it should be more thatn 106

 

That sounds really hard trying to degree the cam if its not dot to dot, lol.

Here it goes, since it sounds like you may even have the cam off 180º

The dot on the cam gear should be at 6 oclock. The dot on the crank gear should be at 12 oclock. These dots should be lined up perfectly with each other.

The cam dowel pin should be at 3 oclock.

Use the dots and keyway in the middle of the picture shown above. The crank keyway should be at roughly 1 or 2 oclock.

Think i already said most of this, but just making sure. You may want to take a picture of how you have it set up and post it before putting it back together just to make 100% sure you got it.

 

110 traps in that DA should be cake. Something is surely wrong. Get the cam situation fixed, then we can go from there

Here is a picture of the stock chain.
http://www.streetillusionsracing.com...l/Cam/dots.jpg

You can see the cam dowel location, dots lined up, and the crank keyway. This is how it should look when it goes back together

 

for some reason i wanted to put the motor back together with
#1 TDC (dowel pin at 9 o'clock, both dots at 12 o'clock) instead
of the conventional way:
#6 TDC (dowel pin at 3 o'clock, crank 12 o'clock. cam 6 o'clock)

now looking back that wasnt smart
oh well live and learn,
ill let you know what i find.
i just cant believe it would start,idle,run so smooth and the timing be off a tooth.....i hope thats what it is, something simple.

thanks jared
