I would adjust the valves since you just bought the quad, for peace of mind, then if the rattle is still there look for a loose part.

I do not know the actual reason why it would do this, but try to tighten every nut and bolt ect. as metal expands when hot and this could mean it then presses against something hence the reason why it stops...... just a thought, hope it helps. :P

Setting of timing chains


Get Ford timing tool kit, part = otc-6488 (For about $119 USD on eBay)

4 timing chains (3 front including the optional balance shaft chain + 1 back)

2 cam guides (1 front + 1 back)

2 oil tensioners (1 front + 1 back)

1 jackshaft tensioner (1 front)

1 jackshaft guide/cassette (1 front)

1 balance shaft tensioner (1 front) (will probably be ok, so dont replace it)

1 balance shaft guide (1 front) (will probably be ok, so dont replace it)

new sprockets + bolts + gaskets etc.

new spark plugs + throttle body cleaner + lithium grease spray + oil change

head gaskets


some of these parts (the front stuff) can be obtained as a primary timing chain rattle noise kit Part# = 2u3e-6d256-** ab for 4*4 & bb for 2*4.

The kits also have later part numbers for us$ 76 @ http://www.fordpartsonline.com


My parts order (without the balance shaft stuff) was:

$76.04 KIT-TENSIONER TIMING 2u3e-6d256-ab

$47.93 Engine, Camshaft and timing, Timing chain, TIMING CHAIN, Explorer, Mountaineer, Rear - 4.0L SOHC - 4.0L SOHC

$57.36 Engine, Camshaft and timing, Chain guide, CHAIN GUIDE, Explorer, Mountaineer, Jackshaft To Cam - 4.0L SOHC - 4.0L SOHC

$103.22 Engine, Overhaul gasket set, OVERHAUL GASKET SET, Explorer, Mountaineer, Upper (Valve Grind) - 4.0L SOHC - 4.0L SOHC

$28.93 Engine, Camshaft and timing, Tensioner, TENSIONER, Explorer, Mountaineer, Upper - 4.0L SOHC - 4.0L SOHC

Its worth mentioning that this procedure is not enjoyable at all and should be undertaken with at least 8 full days to completion (I recon you could do it in half the time the second time).

It is basically on entire engine re-build with both heads off and the engine out of the vehicle.

It is not possible to do the rear chain or sprocket with the engine in the car as the flywheel needs to come off + at least 1 head, but it is possible to do the front primary chain and or front cam chain with the engine in the car.

You will be a ford exploder and timing expert after you do this - the main reason should be the love of your American built vehicle. Its a solid car - except for the plastic guides!

Disclaimer Note: This is how i successfully did the job, but i am not a ford mechanic and don't hold me responsible if this does not work for you.
Timing Overview

A Small Sprocket on the crank turns a larger (2 to 1 ratio) jackshaft sprocket that is in turn connected front & back to the 2 camshafts.

Thus a 360o turn of the crank will turn both the camshafts 180o.

Firing order is 1-4 2-5 3-6, Right side numbers 1,2,3. Left Side = 4,5,6.

At TDC pistons 1 & 5 are fully raised, thus 1 is about to spark & 5 is evacuated.

The engine will turn freely (no piston to valve contact) with the cams 180o out, it will even run (roughly) with 1 out 180o, any other settings may cause major damage to the valves.

The 2 cam shafts come with timing markings, "yes" real timing marks that anyone can use (even without special tools) to ensure correct timing.

The way to time it is to ensure both the off centre cam shaft slits are level/flat with the head.

With the engine at TDC both the cams need to have the off centre slot in the same position either up and level or down and level.

It is super critical that both the camshafts are 100% in sink with each other, i.e. not a few degrees off, the engine computer can compensate for crank timing but not engineering failure.

Be warned the camshafts can turn easily fast & hard by themselves as a few springs are compressed at TDC, I got my finger jammed and its still healing + if the engine is not at TDC you may damage a valve.

Now heres the hard thing that you will need special tools for - if you need to change the timing, you will need to be able to undo the cam sprocket bolt on both cams & these are done up real tight.

There is a tool that you attach that has 2 pencil thick shafts that fit into the sprocket and prevent it from turning - then you need to put about 90Nm of force on the bolt (remember the rear one if LHT)

For the $money$, its well worth getting yourself the tool kit - it will save you hours in the long run. Search eBay for otc-6488 should be US $119 - then sell them again for say $100.

There is also a tool version of the oil tensioner in the kit that screws right in and puts the correct amount of force on the chain + guide, to enable you to do up the cam bolt with the chain and sprocket in the right spot on the cam.

I have a rxs but it back fires and stops power at 35/40 mph


With the rattle, i would true the crank. Was there ever an abrupt stop (chain came off and wedged, locked up back tire, etc)? That would indicate crank.

If it had points i'd say they were floating.

Sometimes a plugged exhaust will limit power at a certain rpm, but not explain the rattle (i'm imagining vibration, but it could be something benign). Good luck.

It still sounds like it still running rich. If it doesn't have any performance mods like aftermarket exhaust it wont like the stage 3 kit. The stage 3 kit should be install if it has high performance exhaust and k&n pods instead of an airbox and filter. Or the floats may be stuck or improperly adjusted.

Centre speaker stops functioning


Is the audio for the center channel driven by its own amp? No other channels on it or affected?

Assuming you're not cranking it up to "11" to rattle the walls...

I think what you're hearing is the protection relay dropping out - removing power from the output stages of the amp when the amp thinks something is amiss. If it turns on OK after being OFF for a while and repeats the loop you probably have a heat issue.

A solid click OFF that is not resettable would possibly be a short in the speaker path - shorted speaker wire or speaker.

Check the amp to see if it was hot to the touch or getting warmer up to the point it clicked off.

Is it ventilated properly with no heat-producing components below it? Clean out its vents and make sure it can breath. If it has a fan make sure it's working and has good airflow.

Rattling sound 0-20 mph comes and goes, 6 disc cd changer skips


Howdy,
the rattling sounds like its the hydrolic lifters (tappets or cam followers called also) not really a hard job just a pain cause you've to strip the engine to pieces to do. Its very time consuming so unless you've some experience i'd place this in the hands of an experienced mechanic. This should also stop the smoke problem.

The engine service light is on a timer from service to service so thats nothing to do with it.

The cd player your right about it just need the lazer llens cleaned. You can buy a cd cleaner kit for cheap in any music/record store.

Hope this helps if not let me know and I'll try and find the solution

Cheers
