Tony,

Matt on FordScorpio site is building a 24v one, may have the info you want.

I looked at this a while ago but reckon I'd get more reliable higher revving power out of a huffed BOB, either that or rob a bank and buy a DFV V8 and de tune it a bit for road use   Or of course buy a V8 Jag lump and dress it up wiv some Cossie badges

That Volvo V8 in th V8 section looks nice, and if I'm not mistaken has a Jatco 5 spd Auto on the back....

What transmission do the new Mondeos use....Jatco and its available in the Jags with 4wd tippy and auto programs as standard hmmmm......Is the new Mondy available in 4wd.........Oh dear can see another mortgage pending

Looks Good Tony,

Been reading it all.  Fair play to him for perseverence, he's done an ace job there.  He does seem to have problems when the revs go high though.
I had similair issues 15 years ago when I took a 5.0 Chevy out of one of my boats and built a hot 6.6 litre small block, the grief comes from the rod angles with long strokes at high rpm, they just dont like it and break pistons, small ends and rods.  

Obviously the big capacity engines are very strong torque monsters, as long as you put a real sensible lid on the rpm limit.

The short strokers tho will spin up to 7 grand quite happily with an occasional 7500....Dont know how long the cam chains will last  My last one had all new timing bits but I only did 7000miles with it b4 I sold it.  Was sweet as a nut though when I sold it and I regularly buzzed it to 7 - 7500.

Bottom end was all stock BOB, just new rod bolts and a full balance.

Well I been ordered off to bed, looks like me lucks in  , c ya later

Dave

it cant be this hard!!!!

paul, non of that shows the chains!!!

all i need is drawings/pix to know the parts i need, been looking at some chains/tensioners on ebay usa ($35) these are, one chain, a tensioner and a guide, they seem to be identical exept in the pictures it shows a double lower chain wheel. cant be right as the cams are driven from front on the left and back on the right!!!

just need to see what i need to get

Yeah that's it Tone.

You must call it the SOHC 4.0L or Cossie 4.0L otherwise people will assume it's the old one  

I have the same pictures.  

I should have a Ford Manual for it some where if you want a copy.

Make sure the new parts are 2002 ones as they where re-designed to try & help cure the problem.

9 times out of 10 it's caused by the front chain set-up.

People usaly only replace that one to cure it.

Back chain is a nightmare so hope that's O.K.

The 250 quid job will be just the front one, ask them what they replace.

I myself would rather get my hands dirty as I said

hhmm this could be interesting!!!

im going to inspect it further now as every one jumps at the chains on these, the noise is acualy coming from the back of the engine but it is low down, its laudest just behind the front wheels, im going to check in to it more. wonder if the dirt plate has been bent into the T/C. or  even the cats rattling. its that sort of sound!

also needs ISPV but for a 1998 explorer its in dam good nick...

sinds you said that the car is from '98, i did not know witch 4.0 you meant, i assumed the old one. the 4.0 ohv is used till '99. i did not find many pictures off the chains and guide off the old 4.0.

Look at the states forums Tone.

These engines are famous for the rattle just like the BOBs  

Even think there was a recall in the states for it???????

Anyway it's like a faint rattle that comes & goes with revs.

About 2500rpm should be the sweet spot for it.

Taking the tensioners out & cleaning them may help.

Could be something else but as I say they are well known for timing chain trouble.

i have read about it,,ow and the recall was done on it a few years ago so fingers crossed.... thing is, as you know it was totaly quiet yesterday, yet today she rattled right from start up today!!
(did try and call you so you could hear it)

ok so here is my plan, i am going to try and buy just the tensioners and replace them!

strikes me, that i have one the compresses over night then sticks,(depends on where it stops on the cam) i feel the guides and dog leg are fine at this stage (hence no noise some times) so hope this is the best option if i can get it done as soon as possible.but who sells just the tensioners???????????

time to go see i think!!

I would clean them first & give her fresh oil.

Maybe all it needs.

Well not sure what they are quoting for at 15 quid each (phone call?)

But this is what I make it.

Front LH 4055868 re-designed to 4822186 about 60 quid.

Rear RH 4058617 re-designed to 4822190 about 50 quid.

Two gaskets 4822186 about 9 quid.

& PM your address & I will send the rebuild manual.

ok i removed the drivers side one tensioner (after havinf to buy another 26mm spanner) and replaced it with new, (you can see the diferances easy pix later)
as a test i started the engine and it was rattling like hell. after the change it rattled like hell for 5 mins and started to go quiet.
 20 mins later all is well
just got to try it later and see if its quiet all the time
pix to follow!

  You got a spanner in the end then.    Least looks like you`ve solved the problem mate. Was it easy to strip down and change?

Now the big question, when are we going offroading then????

hmmm not totaly sure if its done the trick yet!
just been out and started it, it did rattle a small amount untill it was warm.
this just might just be air in the tensioner, not sure yet so going to run it for a bit and look at it the next weekend if i get time.

its not a big job at all, infact its very easy to change this tensioner as youl see in the pix!
the engine bay of the ford explorer is rather packed as most things like alternator/PS/air con are mounted hight!


this is the side the tensioner is,, errrmm some where in the dark bit



closer view looking down the spaner (yes its on the tensioner)


and here is the new kit, both tensioners, washers and a resrticter, i am only fitting the short one today due to time!

tensioners alone


now with the old tensioner out, i can see the new modded one clearly


so there ya go, i might be lucky but ether way it wasnt to hard to do!!

foot note....
what you cant see on the pictures of the old tensioner is, it has 4 holes drilled around just above the copper washer,,while the new one has only one larger hole, also on the new one, there seems to be some thing on the  inside of the hole, could be a one way valve, not sure!!

ok update................
 fitted the drivers side tensioner, and the noises reduced

fitted the other side and the chain stopped rattling but i can now hear a wheerring noise,, this i assume is due ti the need of the oil flow resticter,
but tryed to remove the plug and its snapped off in the head

waiting for another day off now
