KA24DE timing question

Ok, so i replaced my head with one i sent to get new valve seals etc. now, when i removed the old head, i marked the dot on the gears with the chain when the engine was on TDC. now when i installed it everything lined up nice and perfect, so i had to turn the engine over by hand in order to put in the tensioner. after that i noticed that every time i went back to TDC, the chain would move half a (sprocket/teeth) from the dot on the gear. im going to post a picture to show you what im talking about. now, since i rotated he engine a couple of times, its off by 1 1/2.
on the picture, what is in red is where the dot and the chain were marked prior to removal.
The yellow circle shows where the dot is now compared to before. now i cant remember where, but i think i read somewhere that it sometimes moves but when the engine turns it fixes itself. also, the cams are in the correct position, the front lobes face outward just like it was before removal. so idk what is going on, is it the tensioner? do i have to remove the chain and install it again?

Thanks


Before, the chain was with the yellow dots on that same position, but now they have move

That's cause of the number of teeth and the length of chains. If everything lined up right when you first installed and you can turn it by hand a few times then your gravy.

ok cool, yeah it turns fine and doesnt make any weird noise so i think im good. btw when putting in the dizzy, can i just leave it where it is (its on TDC) or do i have to crank the engine a couple of times till all the marks align again and then put the distributor in?

ok little update. i installed the head and everything and i started the engine and it started. but while i was inside the car i heard this MASSIVE air/vacuum leak. and the car started dying, so i did it again until i heard where it was coming from, and since it was dark i broke out the flashlight and started looking. turns out a hose got disconected or cut off. its the one in the pic on the intake manifold. now ive been looking and it look likes it belongs to the PCV valve. look at the pic, is that were it connects?
if it is then good/bad. good cause i know where it goes. bad cause its a bitch to get to, and cause i need to get a new hose cause that one is cut off at the pcv valve. another question, does this hose just slip in, into the PCV Valve, or does something hold it in place
?

Thanks

cool, ill see if i can fix that tomorrow, and other than the leak, i didn't hear anything out of the ordinary so hopefully everything is good. i had a little trouble trouble with the dizzy because i would align the shaft with the indentation, but the cap would point a little bit off 1 cylinder, so i went by pictures online and timed it that way along with the shaft and indentation, so hopefully that didnt get fucked up

Shouldn't I've had issues with that too. But mine runs fine. The dizzy that is.
Once you get it all put together and if it still has issues but you can't hear a leak. Spray some carb cleaner around each seal and if the engine changes rpm or sputters then you have a leak there.

k, so after 5 hours, three people, and two hands getting completely cut, i got the hose in and the car idles great. since it was the first start i didn't want to keep it on for long or rev it too much. so i just let it idle like normal. what i did notice was that after i give it a little rev (from 1000 to 1300 rpm) it then came down to under the idle rpm (to 600rpm) and then went back to normal. just wanted to know why exactly it did that now since before that didn't happen. also i have to say that the exhaust isnt hooked up, just the headers if it makes a difference.

Less back pressure and scavenging. Along with everything starting to seat in right now things might act weird at first.
