Question about 2000 Lincoln Town Car

Open Question

How to set the timing on the 4.6L V8 engine

Had to replace the timing gears, chains, guides, and tensioners. I purchased an "e-auto-repair" manual on line, and tried to follow directions as close asd possible. When all was put back together, the engine will turn over freely enough, with NO sound of pistons hitting valves, or other noises, but engine does not start. No backfire, and only a hint that it might start, but never does. Was told by a local mechanic that the right bank camsprocket does not go together as shown on most diagrams, but is actually 180 degrees different from diagrams. Needing much help. Thanks in advance.....and diagrams would be definitely appreciated.

SOURCE: ~70K miles. Timing chain tensioner assembly going

The tensioner going out at or above 50k is a very common problem. The longer you drive without replacing it, the more you risk being stranded with a dead battery or, even worse, a broken belt. Get it taken care of as soon as possible.

Replace your coil. This happens on these older vehicles a LOT as the oil begins to evaporate out of the ignition coil. My '54 GMC used to LOVE to do this.

I have been advsed that I have a broken timing belt or "jumped timing chain.Besides the belt/chain, what other components do you recommend replacing(Gasket/seal,cam and crank pulleys,tensioners)?


I am assuming you have the 2.2L 4 cylinder engine. The timing chain tensioner on these engines is nororious for failure resulting in jumped timing. Be advised that depending upon the situation, you may have sustained major engine damage. If the timing simply jumped when turning the engine off, you may be safe, but if it occurred at highway speed, there is a high probability that there is valve damage in the engine that will need repair before you can move on to the timing chain and tensioner. As far as "other components", if your know that the head is ok, then you should replace the timing gears, chain, and tensioner. Also purchase a "timing gasket set" which will give you the gaskets ans seals you need to do the job.

Timing chain replacement


Timing Chain and Gears REMOVAL & INSTALLATION 1.9L Engine NOTE: The following procedure requires the use of the puller tool No. J-25031 or equivalent, and timing sprocket installation tool No. J-26587 or equivalent.
  1. Remove the timing (front) cover from the engine.
  2. Lock the shoe on the automatic adjuster in fully retracted position by depressing the adjuster lock lever. NOTE: To remove the timing chain, it may be necessary to remove the camshaft sprocket. Before removing the timing chain, be sure to align the timing marks.
  3. Remove timing chain from crankshaft sprocket.
  4. Check the timing sprockets for wear or damage. If crankshaft sprocket must be replaced, remove the sprocket and the pinion gear from crankshaft using the puller tool No. J-25031 or equivalent.
  5. Check timing chain for wear or damage; replace as necessary. Measure distance "L'' (40 links) with the chain stretched with a pull of approximately 22 lbs. (98N). Standard "L'' value is 15 in. (381mm); replace chain if "L'' is greater than 15.16 in. (385mm).
  6. Remove the automatic chain adjuster-to-engine bolt and the adjuster.
  7. To check the operation of the automatic chain adjuster, push the shoe inwards, if it becomes locked, the adjuster is working properly. The adjuster assembly must be replaced if rack teeth are found to be worn excessively.
  8. To remove the chain tensioner, remove the "E'' clip and the tensioner. Check the tensioner for wear or damage; if necessary, replace it. Fig. 1: Timing chain guide and tensioner - 1.9L engine 85383285.gif

  9. Inspect the tensioner pin for wear or damage. If replacement is necessary, remove the pin from the cylinder block using a pair of locking pliers. Lubricate the NEW pin tensioner with clean engine oil. Start the pin into block, then place the tensioner over the appropriate pin. Position the E-clip onto the pin, then (using a hammer) tap it into the block until clip just clears tensioner. Check the tensioner and adjuster for freedom of rotation on the pins.
  10. Inspect the guide for wear or damage and plugged lower oil jet. If replacement or cleaning is necessary, remove the guide bolts, the guide and the oil jet. Install a new guide and upper attaching bolt. Install the lower oil jet and bolt, so that the oil port is pointed toward crankshaft. To install: Fig. 2: Timing chain alignment and installation - 1.9L engine 85383286.gif
    Fig. 3: Inspecting the timing chain for wear 85383287.gif

  11. Install the timing sprocket and the pinion gear (groove-side toward the front cover). Align the key groove with crankshaft key, then drive it into position using installation tool No. J-26587 or equivalent.
  12. Turn the crankshaft so that key is turned toward the cylinder head-side (No. 1 and No. 4 pistons at TDC).
  13. Install the timing chain, align the timing chain mark plate with the mark on the crankshaft timing sprocket. The side of the chain with the mark plate is on the front-side and the side of chain with the most links between mark plates is on the chain guide-side. Keep the timing chain engaged with the camshaft timing sprocket until the camshaft timing sprocket is installed on the camshaft.
  14. Install the camshaft timing sprocket so that it's marked-side faces forward and it's triangular mark aligns with the chain mark plate.
  15. Install the automatic chain adjuster.
  16. Release the lock by depressing the shoe on adjuster by hand, and check to make certain the chain is properly tensioned when the lock is released.
  17. Install the timing cover assembly.

How to install a 2002 FORD EXPLORER 4.6L V8 timing chain. Is there any other parts I should be aware of besides the cam and crank gear, timing chain and guide, tensioner arm and tensioner. My mechanic...


Unless the timing chain suffered a catastrophic failure, ie broke into many pieces, you should not need to replace the cam and crank gears, the tensioner arm and tensioner. The timing chain and guide I can agree need to be replaced, but without a physical examination, you can't just say "replace all these parts". If you do let this mechanic do the work, insist on him giving you ALL the old parts. Then take them to another shop and ask their opinion. You may find the mechanic is honest, but I suspect not.

Timing chain


I'll assume you are going to replace the entire set (sprockets, guides, etc.) which I got from O'Reilly for $79.

First, set engine to #1 TDC.
Remove valve cover, fan shroud, fan, drive belt, water pump, 4 10mm bolts from bottom front of head, and 3 10mm bolts from front of oil pan. Remove lower front shield to remove oil pump. remove oil pump/distributor drive shaft, noting the orientation of the drive shaft.
Remove harmonic balance using correct puller (can be rented from local auto parts store). Remove P/S pump and A/C compressor if necessary. Remove timing cover.

IMPORTANT: Before removing oil thrower and distributor drive gear, note direction of oil thrower.
Remove oil thrower and distributor drive gear.
Remove chain guides, tensioner, chain, and finally both sprockets.
The new crank sprocket can only be installed one way, by aligning groove with keyway. The new cam sprocket will have 3 guide holes on the mounting flange, and you will need to align the knock pin with hole #2. Both sprockets should have a small dot (timing mark) on the right side of the sprocket when viewed from the front.
To install new chain, inspect chain to find the two brightly colored gold links. These two links must align with the timing marks on the sprockets. Assemble and install chain tensioner.

!!! IMPORTANT: Be sure to use new gasket when installing tensioner. Tensioner is oil pressure fed and a leaking gasket could allow chain slack, leading to premature wear or break.
Install chain guides, being sure not to let tensioner pop out.

!!! IMPORTANT: The tensioner must be fully compressed. To accomplish this, loosen the 8mm bolts in the passenger side guide (the shorter one). Compress the tensioner, adjust guide to remove slack, and tighten the two 8mm bolts.
Double check that everything is still lined up properly, and make corrections as necessary.
Install distributor drive gear and oil thrower.

!!! IMPORTANT: Ensure oil thrower is installed facing away from the distributor gear. If not, it could get caught in the distributor gear and destroy the two gears or cause engine lockup.

Before installing timing cover, inspect coolant and oil passages. If there is excessive buildup, a good system cleaner is recommended. Replace timing cover gaskets to prevent oil leakage. The best way to reinstall the timing cover is to remove the oil pan, install the timing cover, and reinstall the oil pan (replacing the pan gasket). If you don't want to do that, simply grease the top and bottom of the timing cover and lightly tap it into place with a rubber mallet. This is to prevent damage to the oil pan and head gaskets.
To install the distributor drive shaft, dab some grease on the top side of the gear to hold it in place, and line it up with the distributor. If you are having trouble lining up the shaft, pull it out and look at it from the top, and you will see that the flange is offset. At #1 TDC, the offset will be towards the front.
Install oil pump, being sure to use new gasket.

!!! IMPORTANT: Failure to replace oil pump gasket could lead to inadequate oil pressure, which will cause severe engine damage.

The remainder of the installation is a reverse of removal, using new gaskets where necessary. Before installing your valve cover is a good time to check your rocker arm clearances. This is also a good time to replace your drivebelt, and any other maintenance items as necessary.
