On my 1.8 volkswagan passat AWM engine,the camshaft drive chain tensioner is knocking,the engine has plenty of oil reaching the top,and the engin runs good.what would make it knock so loud?

Did you take pictures while removing the originals? It's always a good habit. Below are the instructions you need to follow. Your own pics are very helpful when doing a big job like this.

1. Disconnect negative battery (1) cable.
2. Drain cooling system.
3. Remove upper intake manifold.
4. Remove cylinder head covers, crankshaft vibration damper, and timing chain cover.

CAUTION: When aligning timing marks, always rotate engine by turning the crankshaft. Failure to do so will result in valve and/or piston damage.

1. Align crankshaft sprocket timing mark to mark on oil pump housing (2). The mark on oil pump housing is 600 ATDC of #1 cylinder.

CAUTION: When the timing chain is removed and the cylinder heads are still installed, DO NOT rotate the camshafts or crankshaft without first locating the proper crankshaft position. Failure to do so will result in valve and/or piston damage.

1. Remove primary timing chain tensioner retainer cap (2) and tensioner (1) from right cylinder head.

1. Disconnect and remove camshaft position sensor (4) from left cylinder head.
2. Remove timing chain guide access plugs (3) from cylinder heads.

NOTE: When camshaft sprocket bolts are removed, the camshafts will rotate in a clockwise direction.

1. Starting with the right camshaft sprocket, remove the sprocket attaching bolts. Remove camshaft damper (1) (if equipped) and sprocket.
2. Remove left side camshaft sprocket attaching bolts and remove sprocket.
3. Remove lower chain guide (7) and tensioner arm (8).

Hi, this engine uses plated links in the chain to match marks on the gears. See figure and installation procedure below. Let me know if you have any questions and thanks for using FixYa.

1. Install the timing chain by performing the following procedure:

1. Verify that the crankshaft sprocket timing mark is aligned with the mark on the oil pump housing.
2. Place the left side primary timing chain sprocket onto the chain, while aligning the timing mark on the sprocket to the 2 plated links on the chain.
3. Lower the chain with the left sprocket through the left cylinder head opening.
4. Loosely position the left camshaft sprocket over the camshaft hub.
5. Align the plated link to the crankshaft sprocket timing mark.
6. Position the timing chain around the water pump drive sprocket.
7. Align the right camshaft sprocket timing mark to the plated link on the timing chain and loosely position the sprocket over the camshaft hub.
8. Verify that all the plated links are aligned to their proper timing marks.
   

1. Install the left lower timing chain guide and tensioner. Torque the bolts to 21 ft. lbs. (28 Nm).
   NOTE Inspect the timing chain guide access plug O-rings before installing. Replace damaged O-rings as necessary.
   
2. Install the timing chain guide access plug to the left cylinder head and torque to 15 ft. lbs. (20 Nm).
   NOTE To reset the timing chain tensioner, oil will first need to be purged from the tensioner.

1. Purge oil from the timing chain tensioner using the following procedure:

1. Remove the tensioner from the tensioner housing.
2. Place the check ball end of the tensioner into the shallow end of the Tensioner Resetting Special tool 8186.
3. Using hand pressure, slowly depress the tensioner until oil is purged from the cylinder.
4. Reinstall the tensioner into the tensioner housing.

1. Reset the timing chain tensioner using the following procedure:

1. Position the cylinder plunger into the deeper side of the Tensioner Resetting special tool 8186. Apply a downward force until the tensioner is reset.
   

WARNING

Ensure that the tensioner is properly reset. The tensioner body must be bottomed against the top edge of the Tensioner Resetting Special tool 8186. Failure to properly perform the resetting procedure may cause tensioner jamming.

1. Install the chain tensioner into the right cylinder head.
   
2. At the right cylinder head, insert a 3 / 8 in. square drive extension with a breaker bar into the intake camshaft drive hub. Rotate the camshaft until the camshaft hub aligns with the camshaft sprocket and damper attaching holes. Install the sprocket attaching bolts and torque to 21 ft. lbs. (28 Nm).
3. Turn the left camshaft by inserting a 3 / 8 in. square drive extension with a breaker bar into the intake camshaft drive hub. Rotate the camshaft until the camshaft hub aligns with the camshaft sprocket and damper attaching holes. Install the sprocket attaching bolts and torque to 21 ft. lbs. (28 Nm).
4. If necessary, rotate the engine slightly clockwise to remove any slack in the timing chain.
5. To arm the timing chain tensioner: Use a flat-bladed prytool to gently pry the tensioner arm towards the tensioner slightly. Then, release the tensioner arm. Verify the tensioner extends.
6. Inspect and replace the timing chain cover gasket and oil seal.
7. Apply a 1 / 8 in. (3mm) bead of sealer at the parting line of the oil pan and engine block.
   NOTE When installing the timing cover, guide the seal over the crankshaft to prevent damage to the seal-s lip.
   

Install or connect the following:

Timing cover and gasket and torque the M10 bolts to 40 ft. lbs. (54 Nm) and the M6 bolts to 105 inch lbs. (12 Nm)

Accessory drive belt tensioner pulley

Power steering pump

Crankshaft damper

Crankshaft center bolt and torque the bolt to 125 ft. lbs. (170 Nm) using tool 8191

Accessory drive belts

Fan module and electrical wiring harness

Upper radiator crossmember

Negative battery cable

WELL THAT YEAR DOSE NOT COME WITH 1.9 BUT ANY WAY IT SHOULD BE UNDER CAR NEAR RIGHT AXLE OR LEFT SOME TIMES

I'm not sure what you may be "doing wrong", but here is the manufacturer procedure for aligning the timing marks.


^Refer to this diagram during step 12.

^Refer to this diagram during step 13.

^Refer to this diagram for step 19.

1. Align crankshaft sprocket timing mark to the mark on oil pump housing. NOTE: Lubricate timing chain and guides with engine oil before installation.
2. Place left side primary chain sprocket onto the chain so that the timing mark is located in-between the two (plated) timing links.
3. Lower the primary chain with left side sprocket through the left cylinder head opening. NOTE: The camshaft sprockets can be allowed to float on the camshaft hub during installation.
4. Loosely position left side camshaft sprocket over camshaft hub.
5. Align timing (plated) link to the crankshaft sprocket timing mark.
6. Position primary chain onto water pump drive sprocket.
7. Align right camshaft sprocket timing mark to the timing (plated) link on the timing chain and loosely position over camshaft hub.
8. Verify that all chain timing (plated) links are properly aligned to the timing marks on all sprockets.
9. Install left side lower chain guide and tensioner arm. Tighten attaching bolts to 28 Nm (250 in. lbs.). NOTE: Inspect oil ring on chain guide access plug before installing. Replace O-ring as necessary.
10. Install chain guide access plug to left side cylinder head. Tighten plug to 20 Nm (15 ft. lbs.)
11. NOTE: To reset the primary timing chain tensioner, engine oil will first need to be purged from the tensioner.
12. Purge oil from timing chain tensioner using the following procedure:
a) Place the check ball end of tensioner into the shallow end of Special Tool 8186.
b) Using hand pressure, slowly depress tensioner until oil is purged from tensioner.
13. Reset timing chain tensioner using the following procedure:
a) Position cylinder plunger into the deeper end of Special Tool 8186.
b) Apply a downward force until tensioner is reset. NOTE: If oil was not first purged from the tensioner, use slight finger pressure to assist the center arm pin of Special Tool 8186 to unseat the tensioner's check ball. CAUTION: Ensure the tensioner is properly reset. The tensioner body must bottom against the top edge of Special Tool 8186. Failure to properly perform the resetting procedure may cause tensioner jamming.
14. Install the reset chain tensioner into the right cylinder head.
15. Position tensioner retaining plate and tighten bolts to 12 Nm (105 in. lbs.).
16. Starting at the right cylinder bank, insert a 3/8" square drive extension with a breaker bar into intake camshaft drive hub. Rotate camshaft until the camshaft hub aligns to the camshaft sprocket and damper attaching holes. Install the sprocket attaching bolts and tighten to 28 Nm (250 in. lbs.).
17. Turn the left side camshaft by inserting a 3/8" square drive extension with a breaker bar into intake camshaft drive hub and rotate camshaft until the sprocket attaching bolts can be installed. Tighten sprocket bolts to 28 Nm (250 in. lbs.).
18. Rotate engine slightly clockwise to remove timing chain slack, if necessary.
19. To arm the timing chain tensioner: Use a flat bladed pry tool to gently pry tensioner arm towards the tensioner slightly. Then, release the tensioner arm. Verify the tensioner is armed (extends).
20. Install the timing chain cover, crankshaft damper, and cylinder head covers.
21. Install camshaft position sensor and connect electrical connector.

Hope this helps!

from what you are describing it sounds like a lifter/valve issue, i am a ford man i don't know if toyota do the same thing, but if they use inserts for the valve seats it is possible a valve seat has been dropping just has not dropped fully out to cause engine damage. buying a new engine will actually cost you less than an overhaul/rebuild anymore. the parts will cost you almost as much as a new motor will with all the machining that maybe needed.
