    did you just put the belt on randomly ? and did you rotate the engine by trying to start it ? do you just need timing belt installation instructions?

Hi there.... I'm assuming you have the head back on. the easiest way is to try and line up the timing marks an the pulleys and install the timing belt. If you have done this and the timing marks line up as they should, you can take the sparkplug out of the #1 cylinder and manually turn the engine over till you can feel air pressure coming out of the plug hole. continue turning the engine till you can't feel anymore pressure. Don't go too far cause then you'll be on the intake stroke and you'll have to turn the engine the opposite way. with the #1 cylinder at TDC, take you distirbutor and cap and figure out what position the rotor should be at for #1 plug. Mark the distributor somewhere where that position is ( where the #1post on the cap should be). Finally insert the distributor and try to get the rotor as close to that position as possible. remember when you install the distributor, The rotor position will move due to the gear set up. Once you have the distributor istalled, you can adjust the distributor for timing by turning it. Hope this helps you out. If you have any other questions, please don't hesitate to ask..

Thanks
Phil

I accidently took the distributor out on a 1992 4 cylinder izzuzu pickup, while doing some mechanic work. How do I put it back on without having to time the whole motor again?


The best way is to turn engine over to #1 cylinder, turn by damper pulley. Remove #1 spark plug first and put a straw or similar device in plug hole on top of piston so you can tell when its at tdc. Just before #1 piston goes down thats tdc. To replace distributor put it back in with rotor button pointing to #1 wire in cap,tighten, replace the plug then start vehicle When vehicle starts adjust distributor by turning it either way. God_bless!

How can I get the timing right?


The static timing must be set at TDC of number 1 piston. I suspect removal of the cover will be required.

Im trying to get the over head cams in time


you cannot just replace timing belt without special tools like OTC #6474, and camshaft alignment 303-465 timing peg.
always put #1 piston at TDC.

Head was pulled without marking gears or ignition. how do i start from scratch


You need to turn the engine over and bring it up to top dead center (TDC). Aline your put the chain or belt on. The crank gear will be on you just will need to aline the cam gear as I believe it is overhead cam. Do NOT force the cam gear to turn as you can bend your valves. When you are putting in the distributer as you slide it in it will rotate a bit. Make sure it is alined to where your rotor will be faceing to the #1 position on the cap. I hope you understand. If need be I can look up the timing marks for the cam for you just post a comment if you need. When I say to bring to TDC you turn the engine over to where the # 1 piston is to the top of the cylinder. Hope this helped and good luck.

To set the timing you should turn the No.1 piston to TDC, then turn the cam to where both valves on No.1 are close. The timing mark on the sproket should now be in line with the mark on the cilinder head. With No. 1 still on TDC fit the chain.
After fitting turn the engin a few times by hand to make sure there's not a valve pushing against a piston.

Removed distributor to change head gasket, now timing is way off


If the timing chain is still in the correct position its an easy fix. Put screwdriver down spark plug hole #1 and rotate the engine over by hand until you reach TDC e.g. piston fully up. Now your either on the start of the ignition/power stroke or at the end of the exhaust stroke. Im not sure of the firing order of your specific engine but basicly this means that the engine is either firing on 1 at TDC or its firing on its other piston. Just put the screw driver down the other cylinders and find the other piston thats at TDC. Put the distributor back in so that the rotor button lines up roughly with the post on the cap that lines up with one. Put the cap back on and try and start it. If it almost starts just trim up the cap a little (twist it by a few degree either way) If it sounds way out then pull the distributor back out and line it up with its mate piston.
Hope this helps

Still need advice


Turn crank so that timing mark on front pulley is at 0 degrees.
Remove the timing cover and you should see a mark for the cam to line up with.
You want the cam lobes on No.1 cylinder to be pointing away from the followers wether they be rockers above cam or buckets below. This will be the compression stroke.
Once the cam timing is set you can recheck the distributor. It should point to No.1.

I'm replacing the head gasket on my friends 96 Saturn SL1 SOHC. I've heard 2 different stories about lining up the crankshaft with the camshaft in order to keep the valves from contacting the pistons. my...


Bring the crank to TDC while WATCHING CAREFULLY the camshaft, making SURE that the pistons are moving in the correct sequence as the valve train. Once you have the #1 piston on TDC, Set up your valve train with what looks to be the most logical position. Then and only then should you consider the factory spec for setting the lead/lag time of the valve train, in degrees. Hope this helps....accordianman
