Question about Cars & Trucks
I had a knocking noise coming from my 5.4 and after i checked all mains and rod bearings i found that the pasenger side timing chain is slaping the plastic guide can anyone help me with the fix
The only fix I know is to replace the chain and gears. There isn't any adjustment for wear. Hope this helps.

SOURCE: Rod bearing knocking
These procedures may be performed with the engine in the car. If additional overhaul work is to be performed, it will be easier if the engine is removed and mounted on an engine stand. Most stands allow the block to be rotated, giving easy access to both the top and bottom. These procedures require certain hand tools which may not be in your tool box. A cylinder ridge reamer, a numbered punch set, piston ring expander, snapring tools and piston installation tool (ring compressor) are all necessary for correct piston and rod repair. These tools are commonly available from retail tool suppliers; you may be able to rent them from larger automotive supply houses.
Remove any splash shield or rock guards which are in the way and remove the oil pan.
Using a numbered punch set, mark the cylinder number on each piston rod and bearing cap. Do this BEFORE loosening any bolts.
Loosen and remove the rod cap nuts and the rod caps. It will probably be necessary to tap the caps loose; do so with a small plastic mallet or other soft-faced tool. Keep the bearing insert with the cap when it is removed.
Use short pieces of hose to cover the bolt threads; this protects the bolt, the crankshaft and the cylinder walls during removal.
One piston will be at the lowest point in its cylinder. Cover the top of this piston with a rag. Examine the top area of the cylinder with your fingers, looking for a noticeable ridge around the cylinder. If any ridge is felt, it must be carefully removed by using the ridge reamer. Work with extreme care to avoid cutting too deeply.When the ridge is removed, carefully remove the rag and ALL the shavings from the cylinder. No metal cuttings may remain in the cylinder or the wall will be damaged when the piston is removed. A small magnet or an oil soaked rag can be helpful in removing the fine shavings.
After the cylinder is de-ridged, squirt a liberal coating of engine oil onto the cylinder walls until evenly coated. Carefully push the piston and rod assembly upwards from the bottom by using a wooden hammer handle on the bottom of the connecting rod.
The next lowest piston should be gently pushed downwards from above. This will cause the crankshaft to turn and relocate the other pistons as well. When the piston is in its lowest position, repeat the steps used for the first piston. Repeat the procedure for each of the remaining pistons.
When all the pistons are removed, clean the block and cylinder walls thoroughly with solvent.

SOURCE: I was told I have
1. For find out which rod bearing is out of order you need to use an engine stethoscope.
2. You can replace the bad rod bearing with the engine in the car, by removing the oil pan and the cylinder head. I strongly recommend you to replace all rod bearings of the engine, (one complete kit).
