Question about Ford E-250

1 Answer

I am trying to set the timing on my 1996 Ford E250 4.9 Ltr 6 cyl. I would like to know where is the appropriaate marks to use for zero degree. I have brought the number one cyl to tdc but the marks on the damper dont't line up and when they strt to line up the cylinder is quite a ways back down the block.. I went under the car and there is a pointer next to the vibration damper is this what I use for the zero degree mark on the damper to set the timing manually? I replaced the distributor because I change the pick up coil inm the distributor now it would not start I have fuel an spark but she just crank and don't catch or even try to catch CptTrevor

    I was able to finally find the time to fix the timing I have it started and running smoothly now there is another problem the check engine light came on after all of this and it was not on before this episode. I ran a scan with my OB11 scanner and the following codes came up the first one is PO125 insufficient coolant temperature. the second code is P1131 Lack of Ho2S2 Switch Lean(1/1). the last code is P1151 Lean Ho2 switch right bank. Here is my question could this have happen when I was dumping so much gas trying to fix the timing and getting the van started because I had to take the plugs out a couple of times and dry them off they were flooded with gas. If not what is the fix? can I just erase the codes and see if they return. The first code I can just check the coolant level in the radiator? Please advise how to proceed. CptTrevor

    What about the insufficient coolant temperature? this code is going to go away when the battery is disconnected for five minutes?

Do you have the timing jumper removed near the ignition module that disconnects the computer from controlling the timing? and yes the pointer is what u line the marks up with, the setting is 10 degrees before top dead center (BTDC) with the timing jumper block removed. u must have this way out of time if it won'tr start, if u wan to call me in the next few will explain how to get the distributor back in correctly. 925-459-0571, it has to been in the next 30 minutes as I am going out.

    there is more than one set of timing marks this clarifies the right one, it is from a ford owner site

    Hi, Ok here goes. Ford in all its infinite wisdom put two sets of timing marks on the 300. There is one set on the right hand side near the top of the timing cover, these marks are cast in the cover. These naturally are the WRONG marks. On the left side of the timing cover where you can't see them are the right marks. They are on a metal plate bolted to the cover using the cover bolts. The vibration damper also has two sets of marks, wouldn't you know it! There is a large square notch , nope not the right one . There is also a very thin scribed line on the damper, yep that is the right one. .
    To do this right, slide under the engine and clean off the thin scribe line and paint it white and while you are under there you can see the bolted on timing mark on the cover there is a large triangle cut in the plate , that is 10 degrees before TDC the correct setting .Pull your distributor cap and crank the engine until the rotor points at number one cyl on the cap.Then see if you can see the alignment of the timing mark on the damper some how and the mark on the bolt on plate, its easier when the engine isn't running and you can stick your head in there without loosing half of it. Your timing marks should be some where near each other. Crank the engine to align the 0 degree mark and the mark on the damper, don't worry about the distributor position. Just line up the marks. Then go to the right side of the cover with the cast in marks( that you can see) and mark the damper with white something, paint even whiteout works.Now you have a new timing mark that you can see. Pull the spout, yes it is in the same harness as the distributor connector, its a gray jumper.Put the cap back on. Start the engine and use your new marks to set the timing at degrees before TDC.
    Of course this only works if your cover has the cast in marks, I have a 90 and it has the marks. I have just finished assembling the engine and found out that the engine was set using the damper line and the cast in marks. I figure the engine was running 40 degrees retarded, but MAN did ever start quick in any weather with any oil at any temp.
    There are other way to do this but it takes too long to describe them here.Sorry I almost forgot. When you mark the damper with the new mark it should be marked the same as the left side original, i.e.--
    if the original marks are aligned at 0 you should paint your new mark to align at 0 also, if the original is at say 6 your new mark should be painted to be in line with 6 on the cast marks and so on.

    disconnect the battery for 5 minutes and this will reset the the check engine light and erase the codes, then drive a mixed cycle of stop and go, highway speeds and idle time, if the light doesn't come back on you are done, and yes you may have created this condition while fooling around with he timing.

Regaurding firing order on 1993 chevy G20 350 small block is 1 8 4 3 6 5 7 2 but WHERE does number 1 START? ... clock wise I was told and there is a manifacture raised line between two posts IS THAT WHERE...

Yeah, likely that raised line is your starting point. #1. Try lining up your crankshaft pointer(turn with a socket wrench on crank pulley) to 0 degrees. If you are on compression stroke on cyl. 1, your rotor will be pointing to no. 1 plug tower. If you are on exhaust stroke of no. 1 cyl., then your rotor will be exactly 180 degrees off. If you are confused, just turn your crank clockwise one turn (360), and line up zero again. Now your rotor will be (again) either pointing to No.1 position, or 180 degrees off (pointing in opposite direction)One of those positions should line up with that manuf. mark. (Here is easiest way to find TDC of #1 cyl. on compression stroke: pull #1 plug out. Hold finger or thumb over hole, while turning crank, when you feel pressure building on cyl, you are approaching TDC of compression stroke. Just turn crank (clockwise) till pointer is on zero. Done!) Now your rotor will definitely be pointing to #1 plug on your dist. cap.

Want to know how to set motor up for top dead centre on number1 to replace distributor

There is a timing mark on the timing chain cover. Some have a little tube. The bottom center of the engine where the crank shaft is there is a harmonic balancer. The balancer has a line on it. Get the line right on the 0 degrees mark. This will be top dead center.

Firing order and timing for 292 ford

The firing order is 1-5-4-8-6-3-7-2, distributor turns counter-clockwise. The ignition timing can be set using marks on the vibration damper. The wide mark is TDC (Top Dead Center), each mark after the wide mark represents 2, 4, 6, 8 and 10 degrees before TDC. Set timing 3 degrees BTDC (Before Top Dead Center). In addition, valve timingis set like this: Intake opens: 12 degrees BTDC
Exhaust Closes: 8 degrees ATDC

91 f150 4.9L no visible timing marks, hard start runs rough.

I have wondered why this happens many times in the past. You would think the marks should line up using #1 cylinder but they don't.
It has been a while but I think if you hook up to #5 ignition wire the marks will come up for you.You will need to undo the "spout" connector before setting it to 10 degrees before top dead center. The spout is a two wire jumper clip that should break out of the harness at the distributor.
Warm the engine up for a while so it doesn't stall as easy while you set the timing.

Need timing marks for 2002 ford explorer 4.0 engine. trying 2 check timing chain. any one know specs

There are no marks on this one. There is a special tool set to align camshafts ($900). The best you can do is to bring #1 cyl to TDC compression with both cam(valve) covers off. #5 cyl should have lobes at equal opening, exhaust just closing and intake just opening.. #1 cyl cam lobes should each be diametrically opposed to the positions of #5. If cams need to be moved, there is no registration of gear onto cam. Just loosen bolt holding gear and move cam. Retighten bolt. Roll thru 2 crank revolutions and check cam timing again.Simple.

I dont think that u have a timing probing but just to be sure I would recheck the timing, (remove timing belt cover, set crank to zero and make sure both cams line up with the marks on the engine) if thats all good the u have a prob with that particular cylinder. first thing I would do is swap the coil pack from cyl 3 with another cylinder (like cyl 1) then start the car if the misfire code goes from P0303 (Cyl 3) to P0301 (Cyl 1) then u know u have a bad coil pack. try that and let me know what happens
