[87mk3]

hello people im pretty sure this question waz ask befor but how do time the
7m motor any is there any easy way to do it please let me know im trying to get this motor up and runing again

Yeah, line up the marks. If you want ignition time, get a timing light, and line up those marks in diagnostic mode.

i took off the head to clean it and check for a bhg but it waz all good so i put it back together and and line the arrow up i kinda spun the lower pully dose the throw the timing off ??

If the timing belt is installed it all moves together so it doesn't matter. Without just line everything up TDC and get the belt on.

If you spun the pulley when the head was off or the timing belt was off of the cam gears, then yea, it's off. You'll need to rotate the crank to where the #1 piston is at it's very highest point (TDC) and then reset the cams per the TSRM proceedure, THEN you can put your belt back on and do the igition timing next.

how do know where #1 position is ??i tryed to take the bolt that is holding the pully in place out but it wont buge....

 

[bountykilla0118]

2ways that i know of i personally like #1 .....
1) open the oil cap and look down to see where the cam lobe is pointing and you want it to be pointing up.
2) remove the spark plug for the #1 cyl and put a long screw driver in it and you want the screw driver to be all the way UP

Line the mark on the crank up with the indicator on the timing cover plate.

Or take the #1 spark plug out and watch the piston come to TDC.

uh ... im lost i wil post up a pic of what motor look like tonight then u can tiell me wat to do because right now both of the cam cover are off

 

[1987turbo]

yeah take out the #1 spark plug wait for tdc then alighn all your marks on the cams and your all set

2) Wooden Chopstick is safer

If he has the front covers off there's a TDC mark on the inner case and on the lower timing pully.

lol (chopstick) i dont know was the a racial slur or some real advice lol jk yeah ima try to use a chopstick

 

[Mk3runner]

I timed mine using the crank pulley lined up with the marks, then lined the cams up, then found the thread where it says how to line the cps up for TDC.

when I went to smog I was 1 degree off. probably when I was tighting the cps down I moved it. but shit still good if your not building a hot rod.

LOL no slur it was real advice

here's the installation of the timing belt:

here's the cam position sensor:

I usually install the cps several times, each time pulling it out and making sure the grooves are still lined up. Just to be sure that when I do leave it in, it's not a tooth off. (because the end likes to spin pretty freely when you bump something)

 

[87mk3]

This the how the motor look like as of now. Can i time it like this or do every thing have to go back on??? I also have a pic of the befor and after i painted the door panel. I took the pic with my phone cam so they suck but its the best i can do for now

 

[starscream5000]

You need to take the timing belt off, then begin re-timing the motor to TDC for #1 piston per the TSRM specs, then you can put the belt back on.

BTW, you only need to take the belt off of the cam gears, not all the way back off .

 

[87mk3]

ok cool thanx bro

 

[87mk3]

so what number should the lower pully line up with 0 5 10 15???
