TDC on the intake stroke ?

Testimonial: "Idk what exactly you mean... a beginner mechanic who did this job just off youtube videos was this guy.. I thought I had chain perfectly matched with sprockets and oil pump mark, and #1 piston up top... when i tried cranking it I got a backfire.. thinking jumped off time and ready to break it down again. but what did you mean tdc on intake stroke?? And thanks for any and all advice, this is getting frustrating.."

I'm not sure what you may be "doing wrong", but here is the manufacturer procedure for aligning the timing marks.

^Refer to this diagram during step 12.
046beb2.gif
^Refer to this diagram during step 13.
95add8f.gif
^Refer to this diagram for step 19.

1. Align crankshaft sprocket timing mark to the mark on oil pump housing. NOTE: Lubricate timing chain and guides with engine oil before installation.
2. Place left side primary chain sprocket onto the chain so that the timing mark is located in-between the two (plated) timing links.
3. Lower the primary chain with left side sprocket through the left cylinder head opening. NOTE: The camshaft sprockets can be allowed to float on the camshaft hub during installation.
4. Loosely position left side camshaft sprocket over camshaft hub.
5. Align timing (plated) link to the crankshaft sprocket timing mark.
6. Position primary chain onto water pump drive sprocket.
7. Align right camshaft sprocket timing mark to the timing (plated) link on the timing chain and loosely position over camshaft hub.
8. Verify that all chain timing (plated) links are properly aligned to the timing marks on all sprockets.
9. Install left side lower chain guide and tensioner arm. Tighten attaching bolts to 28 Nm (250 in. lbs.). NOTE: Inspect oil ring on chain guide access plug before installing. Replace O-ring as necessary.
10. Install chain guide access plug to left side cylinder head. Tighten plug to 20 Nm (15 ft. lbs.)
11. NOTE: To reset the primary timing chain tensioner, engine oil will first need to be purged from the tensioner.
12. Purge oil from timing chain tensioner using the following procedure:
a) Place the check ball end of tensioner into the shallow end of Special Tool 8186.
b) Using hand pressure, slowly depress tensioner until oil is purged from tensioner.
13. Reset timing chain tensioner using the following procedure:
a) Position cylinder plunger into the deeper end of Special Tool 8186.
b) Apply a downward force until tensioner is reset. NOTE: If oil was not first purged from the tensioner, use slight finger pressure to assist the center arm pin of Special Tool 8186 to unseat the tensioner's check ball. CAUTION: Ensure the tensioner is properly reset. The tensioner body must bottom against the top edge of Special Tool 8186. Failure to properly perform the resetting procedure may cause tensioner jamming.
14. Install the reset chain tensioner into the right cylinder head.
15. Position tensioner retaining plate and tighten bolts to 12 Nm (105 in. lbs.).
16. Starting at the right cylinder bank, insert a 3/8" square drive extension with a breaker bar into intake camshaft drive hub. Rotate camshaft until the camshaft hub aligns to the camshaft sprocket and damper attaching holes. Install the sprocket attaching bolts and tighten to 28 Nm (250 in. lbs.).
17. Turn the left side camshaft by inserting a 3/8" square drive extension with a breaker bar into intake camshaft drive hub and rotate camshaft until the sprocket attaching bolts can be installed. Tighten sprocket bolts to 28 Nm (250 in. lbs.).
18. Rotate engine slightly clockwise to remove timing chain slack, if necessary.
19. To arm the timing chain tensioner: Use a flat bladed pry tool to gently pry tensioner arm towards the tensioner slightly. Then, release the tensioner arm. Verify the tensioner is armed (extends).
20. Install the timing chain cover, crankshaft damper, and cylinder head covers.
21. Install camshaft position sensor and connect electrical connector.

Hope this helps!

I don't have specialty tools I need to get a new timing chain on a 2008 Hyundai sonata 2.4l I'm trying to get top dead center on the compression stroke if anyone can help
Getting the engine to top dead center (TDC) on the compression stroke is an important step when replacing the timing chain on a 2008 Hyundai Sonata 2.4L. Here are the general steps to follow:
1. Locate the timing marks: Look for the timing marks on the crankshaft pulley and the camshaft sprocket. The crankshaft pulley should have a mark on it, and the camshaft sprocket should have two marks that need to be aligned.
2. Rotate the engine: Rotate the engine by hand using a socket wrench on the crankshaft bolt. Turn the engine clockwise until the timing marks on the camshaft sprocket are aligned.
3. Check the piston position: Remove the spark plug from the number one cylinder and use a long screwdriver to feel for the position of the piston. When the piston is at the top of its stroke, you will feel resistance.
4. Adjust the position: If the piston is not at TDC on the compression stroke, rotate the engine again until it is. You may need to rotate the engine several times to get it in the correct position.
5. Double-check the timing marks: Once the piston is at TDC on the compression stroke, double-check the timing marks on the crankshaft pulley and the camshaft sprocket to ensure they are still aligned.
Once you have confirmed that the engine is at TDC on the compression stroke, you can proceed with installing the new timing chain. It's important to follow the manufacturer's instructions carefully and to torque all bolts to the correct specifications. If you are unsure about any step of the process, it may be best to consult with a mechanic or seek further guidance from an expert source.

I have a 2007 Saturn vue 2.2l and it cranks but won't start
50 causes, want to guess wrong 50 times
its not a dead started. nor dead battery. nor bad alternator at this point.
the word is start, not turns over, the starter motor and engine both turn over called spinning, he engine then spins(turns) and then spark burns the fuel so spark is first.
not start using jumper cable car top car other car running,
like the AAA auto club tow man does 100 times a day.
?
if dead , check spark, fuel can not burn lacking good spark\
we test all spark plugs for strong spark
if you did the chain wrong the cam is time wrong and now cam and spark are timed wrong. and compression is 1/2 normal and is now 3 ways wrong. see? chain wrong cause 3 wrongs
and on modern cars newer, the PCM sees CMP and CKP out of sync and pcm then cuts spark and cutting spark cuts fuel tool
so now 5 ways wrong
your post did not say at what point that work made engine dead.
your list if events seems wrong. time
runs
new chain
dead , is this it?, seems so to me but I can not watch you mess up.

the chain can not be just thrown on
and TDC happens 2 times on 4 cycle engines
the correct TDC must be used per the manual.
some use #1 firing other cars use #4
or just match marks crank and cam,

L61 engine with chain balance shaft.
cam chain, shows 7 tools to do this job , ouch
step 22
Rotate the crankshaft in the engine rotational direction clockwise, until the No.?1 piston is at top dead center (TDC) on the compression stroke.
ahhhh yes very tricky timing settings to avoid piston valve hITS
steps:
Rotate the crankshaft in the engine rotational direction clockwise, until the No.?1 piston is at top dead center (TDC) on the compression stroke. set chain color cap to crank cog mark
then at cams, 2 more chain caps at:
set EXH mark cam to chain colored cap
  1. Using the dampener, rotate the crank so that the mark on the timing chain drive sprocket is at 5?o'clock position.
  2. Set the crankshaft to 60?degrees before the top dead center.
position the exhaust camshaft with the offset slot to 2?o'clock position.EXH mark.
Position intake camshaft with offset slot to 11?o'clock position..
INT mark
all; 3 marks must be correct or bend valves you will
if set wrong DO IT AGAIN> now, keys in pocket.
this is an INTERFERENCE engine,
use DUE RESPECT OF THIS or huge damage happens./

I replaced the timing chain and sprockets, now my distributor will not line up with the 6! What should I do now?
Well , you have a problem.
I'd start again and make sure the number one piston is at top dead center, and the sprockets line up to their dots , they will be alignment marks on sprockets and the casing .
if your not sure go to local machanic and ask for help.
good luck.

if he just turned the cams over by hand then i doubt that he damaged anything as if a valve was open when the piston came to top dead center then it would have stopped moving.the noise isn`t uncommon because the valves springs will make some noise as they are compressed and the rockers will make some noise as they move against the cam lobe and and the valves will make some noise as the valve spring forces the valve shut.if when you aligned the cam marks and they didn`t hit the pistons and stopped you from moving the cams and all timing marks are aligned then you should be okay to start the motor.

Timing chain guide broke..jumped time and broke middle gear.
remove the #1 sparkplug place a long screwdriver in the sparkplug hole point touching the top of the piston turn the crankshaft around until the screwdriver is almost pushed out (top dead center)
check to see that the distributor rotor is pointing at the #1 sparkplug wire it must be; if not: turn the crankshaft again until it does
then turn the camshaft around until both valves above the #1 piston cylinder are closed
this is correct; now find the marks on the belt camshaft sprocket gear and, crankshaft gear aline the belt marks with the gear marks and, install the belt

Nissan navara 1986 2.4L petrol timing problem
For timing, on 1981 and later 4 cyl engines (from the Haynes manual):
1. Turn camshaft so both valves for #1 cylinder are closed, and turn the crankshaft so #1 piston is at top dead center (woodruff key should be pointing up).
2. Engage the camshaft sprocket (with stamped numbers facing out) into the timing chain, and install the chain around the crankshaft sprocket. The bright links on the chain should be aligned with the timing mark on the crankshaft sprocket (on the right side as you look at it) and with the number "2" stamped into the camshaft sprocket, which should also be on the right side as you look at it.
3. Install the camshaft sprocket onto the camshaft, aligning the camshaft dowel pin with the number "2" hole near the center of the sprocket.

For the firing order and wiring routing for the 8 plug 4 cylinder engine: (Plugs on the intake manifold side are coded "I", and on the exhaust manifold side are coded "E")

Wire to 1I should be connected to tower on the distributor facing directly to the front of the vehicle. Going counterclockwise from there, the order is (1I), 2E, 3I, 1E, 4I, 3E, 2I, and 4E.
