and maybe advance a few degrees? i have a timing light.

thanks rab

Take off the timing belt cover, and shoot the light at the belt, not too sure where, i belive its one of the cams. To advance, there is a really good write up on escortracing.com in the Hot-To section. Hope this helps.

Well, elscotto80 has one thing right, you have to use a timing light. Other than that, just pointing it at a timing belt won´t get you anywhere. There is a difference between cam timing and ignition timing. I´m assuming you are talking about ignition timing in ths case. Cam timing refers to the relationship of the cam(s) to the crankshaft, and the point where the stroke of the piston is when the valves open. Ignition timing refers to when the sparkplugs fire in relation to where the piston is in the stroke. I could go into a huge technical description of how this works, but for the sake of boring everyone to death I´ll get right to how to check ignition timing. On your crankshaft pulley there should be a notch. you might have to turn the pully a few times by bumping the starter, or by hand if you have G.I. Joe Kun-fu grip. Anyway when you find the notch toke some white out or any white paint and paint the inside of the mark. This will make setting the timing a lot easier, trust me. The notch reperesents the #1 pistons location. If there is more than one notch you will need to Check a chilton, or see if the emission sticker under the hood says what mark to use. I have an 89 with a 1.9L HO and it has the diagram on the cam cover as well as timing specs. After that if you have a TFI ignition (module mounted to the distributor) you will have to disconnect the SPOUT connector. It is a little black connector close to the distibutor that has a plug in it that you can pull out. that will dissable the timing advanve. Ok now that you have done that hook up the timing light. Red clip to positive battery post, black clip to ground or negative post, and the third wire to the #1 spakplug wire.(The wire closest to the pulleys) Now start up the car, and the light should start strobing. The light blinks everytime the #1 spark plug fires, so pointing it at the pulley will show you the relationship of the spark to where the #1 piston is on it´s stroke. There should be a pointer somewhere near the pulley. Mine is molded in to the timing belt cover. it looks like basicly like this ^^^^^. excepy oneof the points is taller than the other. the taller one is know as TDC(Top Dead Center) and is right where the crank pulley would be when the #1 piston is all the way up. Timng is measured in degees BTDC(BeforeTDC) since you want the spark to happen right befor the piston gets to the top and stars heading back down. My timing specs are 10 degrees BTDC I believe. Double check the emissions sticker to make sure what your are. Those other marks on the timing pointer reperesent degrees. I believe they are 2-3 degree increments. So now you loosen(Not Remove!!) the bolt(s) holding your distributor in place just enough so you can turn it. Point the light at the notch, and the timing marks, and turn the distributor left or right until the notch lines up with the appropriate timing mark. Hold the distributor in place, and re tighten the bolt(s). Be careful not to go too tight and strip them or the hole threads(Trust me it SUCKS) turn the car off and reconnect the SPOUT connector. Now your timing is reset to factory specs. If you want to know more, let me know. I can also tell you how to find the best timing for your car, but that is a whole new post alltogether. Good Luck.

lol those are always good

and i do like the novel of a post, verymuchso useful!

Thanks, I´m glad to know that atleast one person out there will benifit from the info. If anyone else has any technical questions, throw em at me. At least my degree won´t be a total waste.

Hot-To, i love how i type!

hey man about that timing i just replaced a cylinder head and i want to get the best performance outa my timing i have the same car as u a 89 egt . please help me with some info or step by step process or something
thanks
