Question about 1983 Ford Escort Gt

1 Answer

How to time a camshaft without a cam card the manufacturer of a camshaft will provide the amount of degrees the cam should be timed at, lets say 108 degrees at full inlet lift. if a camshaft did not have this information with it how would you arrive at a figure to time it in to.

Not sure I am following, but it should like instead of simply lining up the marks as one would normally do, you want the theory?
Anyway, the point of a camshaft timing is to not only make sure the intake opens when the piston goes down, closes going up for compression, stays closed while going down for power, but then opens going up for exhaust, but that it also matches the distributer.
The easiest thing to do if a cam had no marks, would be to compare it with the original, and just transfer the marks. If it is more of a "full race" cam, it will have lobes more advanced for opening, but will also have more lobe retention on the other end as well, so will still be symmetric, I believe. In effect a less sharp lobe. Anyway, the angle is always given relative to TDC on the crankshaft.

2008 silverado EGR location on a 5.3 fuel injected v8


Doesn't have a EGR valve ! Has Camshaft Actuator System .
Camshaft Actuator System Description
The camshaft position (CMP) actuator system is used for a variety of engine performance enhancements. These enhancements include lower emission output through exhaust gas recirculation (EGR) control, a wider engine torque range, improved gas mileage, and improved engine idle stability. The CMP actuator system accomplishes this by controlling the amount of intake and exhaust valve overlap. For the 6.0 liter (LY6, L76) and the 6.2 liter (L92) engine, the Park position for the CMP actuator and camshaft is 8.5 degrees before top dead center (BTDC) or 17 crankshaft degrees BTDC. The engine control module (ECM) can only command the CMP actuator to retard the valve timing from the Park position or advance the valve timing back to the Park position. The total range of valve timing authority is 31 degrees camshaft rotation, or 62 degrees of crankshaft rotation. The control range is from the Park position of 8.5 degrees camshaft or 17 degrees crankshaft BTDC, to 22.5 degrees camshaft or 45 degrees crankshaft after top dead center (ATDC).

Understanding Variable Camshaft Timing (VCT)


Variable Camshaft Timing
With all of the gadgets on cars today, most of us find enough to boggle our minds inside of the passenger compartment let alone what's under the hood. Recently, many manufacturers have moved torward VCT's to improve performance, emissions and to eliminate other components. Let's start with the EGR valve or exhaust gas recirculation system. By installing a variable camshaft system on the exhaust camshaft, the manufacturers were able to eliminate the EGR valve, save money, and lower emissions.

VCT's have been installed on exhaust cams, intake cams, both cams and single overhead cams. The system is operated by using engine oil pressure to move a phaser that is mounted to the end of the camshaft and adjusts the camshaft timing while the engine is running. This is a brilliant system and the performance gained is amazing. The oil that is pressurized by the oil pump moves through oil channels to a solenoid that is controlled by the vehicles computer. The computer takes input signals from various sensors, processes the information and sends a signal to the solenoid that operates the cam phaser and in turn, adjusts the camshaft as needed.

How can I keep my variable camshaft system in good working order?
The best way to keep your VCT system is good condition is to perform regular oil changes and use a factory approved oil filter. Use of an aftermarket filter that is not factory approved can damage your engine. The material that makes up the internal portion of the filter must meet strict guidelines to assure that the material doesn't break away and enter the engines oil channels. This could block the oils path to the camshaft phaser and cause conditions such as rough running, noise and poor emissions/fuel economy. Dirty oil is a VCT's worse enemy. A few dollars extra can save thousands in repairs.

How to set timing on 97 toyota corolla 1.6l i have set harmonic balence at 0 degrees and aligned knock pin hole with cam shaft notch still wont start


Camshaft gear pin hole aligns with a notch in the camshaft bearing cap, exactly behind the gear. You do not mention if you checked the marks on both cams, before going into the timing belt. they do not move, unless you removed one or both of the cams.

How can I check if my timing chain needs replaced in my '03 Suzuki Aerio 2.0l. (How many degrees play between crank and cam is too much?)


If the guides are worn into the casing or if it is slapping against the valve cover, then it is time to replace. How many miles are on it?

Passat 2001 with codes P0012,P0340 it runs fine the turbo kicks in no problem I originally found some broken vaccum line and replaced them but the codes still return


P0340 - Camshaft Position Sensor Trouble
Your cam timing timing is off and the sensor is fine. They are very simple sensors...it's just a magnet...and magnets don't go bad. Check the timing. Incorrect allocation means that the camshaft isnt where the computor thinks it should be at any given time. This could be casued by the base engine timing being off by a tooth or by a problem in the camshaft adjuster.


P0012 Camshaft A: Advance Setpoint not Reached
The code P0012 can be set by the following concerns: Faulty cam adjuster, Faulty cam adjuster solenoid, Low oil pressure, Sludged oil passages and Sticky camshaft.

The variable cam timing uses engine oil pressure diverted to the adjuster mechanism by a solenoid duty cycled by the PCM. Low oil pressure or severe oil sludging can affect camshaft timing operation. Always check oil level and condition when camshaft adjustment codes are present.

Using a full function Volkswagen compatible scan tool enter address word 01 (Engine). Function 08 (Read Measuring Value Blocks) and Display Group 091 (Power Enhancement Camshaft Adjustment).

Observe the 4th display field "Active Camshaft Adjustment Angle" With the engine at idle. The 4th display field should read between -3.0 to +6.0 degrees KW if the camshaft is in the normal unadvanced position. Any other reading at idle indicates that the camshaft is shifted from the normal unadvanced position

Accelerate the vehicle from a standstill in 1st gear using wide-open throttle and observe the display in field 4 again. Under heavy acceleration the display should read between +16.0 to +25.0 degrees KW. This indicates that the camshaft has shifted to the full advance position.

If the display in field 4 does not change from the values in test step 2 or if the display changes but does not reach a minimum of +16.0 degrees KW (i.e. between +6.0 and +16.0 degrees KW), the camshaft timing adjuster mechanism is not advancing the camshaft.

Failure to advance the camshaft could be caused by a faulty cam adjuster, a faulty cam adjuster solenoid, low oil pressure, sludged oil passages, or a sticky camshaft.


Hope this helps (remember to rating this free answer and leave ue some testimonial comment)

Need timing blet diagram 1992 ford ranger 2.3


Hi, the crankshaft marks are on the belt pulley and timing cover, so you have to mate it up to see them. The cam sprocket mark goes on the bottom, and aligns with another mark on the timing cover. There is a plug you pull out and hole to look thru to align the cam sprocket/shaft.


jturcotte_1801.gif


jturcotte_1802.gif


Rotate the engine so that No. 1 cylinder is at TDC on the compression stroke. Check that the timing marks are aligned on the camshaft and crankshaft pulleys. An access plug is provided in the cam belt cover so that the camshaft timing can be checked without removal of the cover or any other parts. Set the crankshaft to TDC by aligning the timing mark on the crank pulley with the TDC mark on the belt cover. Look through the access hole in the belt cover to make sure that the timing mark on the cam drive sprocket is lined up with the pointer on the inner belt cover.

How do you set the timming on a 2.3 when your putting the new timming belt on


The IGNITION timing on your Ranger is computer-controlled and is not adjustable.


Should the camshaft drive belt/timing belt jump timing by a tooth or two, the engine could still run; but very poorly. To visually check for correct timing of the crankshaft, auxiliary shaft, and the camshaft follow this procedure:
There is an access plug provided in the cam drive belt cover so that the camshaft timing cam be checked without moving the drive belt cover.
  1. Remove the access plug.
  2. Turn the crankshaft until the timing marks on the crankshaft indicate TDC.
  3. Make sure that the timing mark on the camshaft drive sprocket is aligned with the pointer on the inner belt cover.

Never turn the crankshaft of any of the overhead cam engines in the opposite direction of normal rotation. Backward rotation of the crankshaft may cause the timing belt to slip and alter the timing.

Looking for cam timing mark on diesel 2l motor?


If you don't know what your cam timing mark is and the cam belt is off, make sure that the crankshaft is on Top Dead Centre (TDC). Turn it clockwise using the pully bolt until the timing marks lign up. If you feel any resistance, go back a little and move the cam shaft about 45 degrees as the piston is making contact with a valve. Carry on with the crankshaft until it is right. Take the rocker cover off and turn the camshaft until the inlet and exhaust valves on the rear cylinder are both opening an equal amount. You will see the camshaft lobes pushing them open. If you feel too much resistance move the crankshaft around a little to let the valves clear the pistons, then move the crankshaft back. If you look at the front cylinder, you will see that both valves are fully closed. This is TDC. See if you can find a mark and what it is lining up with. When you have reassembled everything, using a spanner on the crankshaft nut, turn the engine over clockwise for two full revolutions and if it turns without locking up (pistons touching valves) and all the timing marks still line up you can start it up. If your pump timing is still correct, you should be done. Don't run the engine with the rocker cover off or you will get oil everywhere.

Timing marks


this is an easy one to time. the timing mark for the crank is 0 degrees-do not attempt to tum crank if cam timing is out. there is no distributor on this engine-it is advanced with your intake camshaft. The intake camshaft is the only tricky part to time. Be very careful because at 2500 rpm this cam actually moves forward via cam advance solenoid. It will hit your crank if not timed properly! so with your crank at o degrees-camshafts out of head if you need to turn engine to line up crank-on the exhaust cam(your left)behind the gear(on flange) there will be a hole big enough to put a small punch in that will line up with the top of the deck surface on the outer side(to the left). Now on your intake cam(your right) it will be just the opposite. the hole on the back side of the gear flange will line up on the right with the to p the deck surface. once in line hold intake cam and turn the gear(advancer) all the way to the right)-very important. You will have to start with you intake(put chain on) then line up your exhaust and install timing chain tensioner. always turn engine 360 degrees and recheck before you proceed. At least your at top dead center and you can visually see the lobes on both cams mostly straight up. hope I have been helpful.
