I just replaced the timing belt on a vg30de dohc, we have double and triple checked the gear alignment. we removed gears to replace seals, all labelled and refitted to original positions. rotated motor and rechecked valve timing, good. have good spark, fuel pressure good and injector pulse good. when cranking sound like its to far advanced. tested with timing light, found about 45 degrees before tdc at cranking speed. replaced cas sensor with known 2nd hand item, still same symptom. help, its a customers car. thanks

Did you try rotating the CAS input shaft? Remember that the cams spin at half the speed of the crank, so a full spin of the CAS is actually 720 degrees. It could be that the CAS is 360 degrees out of phase and causing the car not to run properly. Unbolt it and remove it carefully. Rotate the input shaft (the part that mates with the cam) 360 degrees and put it back on, and see if that helps.

Also, just making sure, when you double-checked the cam timing marks, you did verify that in addition to the four cam sprockets being aligned properly, the crank timing mark is also aligned correctly, right?

Timing belt


You obviously need to replace your TPS, and you may need a new belt tensioner as well. On these cars the timing belt setup is not about no 1 cylinder being top dead center. Here are the proper steps to do a timing belt on this vehicle:

To change the timing belt first place the right side of the vehicle on a jack stand and remove the right front tire. Remove the plastic cover inside the wheel well to expose the harmonic balancer. Remove the serpentine belt (standard 3/8" rachet will set in the belt tensioner to relieve tension). Remove the harmonic balancer (19mm). Place a jack under the engine on the right side of the vehicle, then remove the engine mount from the top of the fender well, (17mm deep well socket and 17mm wrench required) it is not necessary to remove the mount from the side of the engine. Remove the timing cover, (10mm) it has 2 nuts. Loosen the timing belt tensioner, (10mm) then pry it away to relieve the tension. Slide the timing belt off of the cam gear.

To position the new belt, the cam gear has a arrow on it, and the cylinder head has a small dot. Align the arrow with dot, and make sure it is aligned (the arrow must point up). The crank gear has a notch and the engine has a groove to align the notch. Again, make sure the notch and groove are aligned (they again will be up). Place the new timing belt in position around the crank gear, the water pump and belt tensioner and leave the slack at the top. Again relieve any tension from the belt tensioner, and slide the belt on to the cam gear. Place a slight bit of tension on the belt and tighten the belt tensioner. Use the 19mm bolt from the harmonic balancer and turn the engine 2 complete turns and verify that the cam gear and crank gear are in their proper positions and aligned with the dots and notches. After 2 complete turns of the engine, and verifying everything is still aligned, re-assemble in reverse. No further adjustment is necessary.

Note:There is no timing adjustment for this vehicle, and if you are not properly aligned on the cam gear and crank gear it will not run properly.

Timing


There is no timing adjustment "at all" for a 1999 escort. If your timing is out, your timing belt has slipped and needs to be replaced.

To change the timing belt first disconnect your negative battery cable, then place the right side of the vehicle on a jack stand and remove the right front tire. Remove the plastic cover inside the wheel well to expose the harmonic balancer. Remove the serpentine belt (standard 3/8" rachet will set in the belt tensioner to relieve tension). Remove the harmonic balancer (19mm). Place a jack under the engine on the right side of the vehicle, then remove the engine mount from the top of the fender well, (17mm deep well socket and 17mm wrench required) it is not necessary to remove the mount from the side of the engine. Remove the timing cover, (10mm) it has 6 bolts and nuts. Loosen the timing belt tensioner, (10mm) then use a 3/8" rachet in the belt tensioner to relieve the tension. While relieving the tension slide the timing belt off of the cam gear.

To position the new belt, the cam gear has a arrow on it, and the cylinder head has a small dot. Align the arrow with dot, and make sure it is aligned (the arrow must point up). The crank gear has a notch and the engine has a groove to align the notch. Again, make sure the notch and groove are aligned (they again will be up). Place the new timing belt in position around the crank gear, the water pump and belt tensioner and leave the slack at the top. Again use a 3/8" ratchet to relieve any tension from the belt tensioner, and slide the belt on to the cam gear. Place a slight bit of tension on the belt and tighten the belt tensioner. Use the 19mm bolt from the harmonic balancer and turn the engine 2 complete turns and verify that the cam gear and crank gear are in their proper position and aligned with the dots and notches. After 2 complete turns of the engine, and verifying everything is still aligned, re-assemble in reverse. No further adjustment is necessary.

Note:There is no timing adjustment for this vehicle, and if you are not properly aligned on the cam gear and crank gear it will not run properly.
