Just taken the head off my 3dr to have a bit of a general look see and replace a few gaskets etc, only to find stamped on the side of the block that it's a 200 Block ?
Considering this car is supposed to be totally original, owned by Ford them selves for its first 4 years then stored for 18 of the past 19 years am I correct in thinking someone has changed the block ( the head is def 3dr ) ??
I thought the 4wd 200 block came out with the Escoss and then maybe the 4wd Sapphires.
Can any one help me to sort this out please?
I know its a better block to have, tougher, heavier etc but it should not be on this car
Cheers
Keith

Must've been changed mate, what engine number does it have stamped on it, anything?

CosworthGuy

Perhaps it was changed under warranty at fords when it wasnt very old.

keithscossie

The engine number matches the original registration papers, or the engineer who did the Australian verification said it does.
Now I'm really worried.
However the car is not here so I'll check it out again on Tuesday when I can get access to it ( public holiday here Monday )
Going to be a long weekend ( literally )

keithscossie

I dont think it could have been changed at Ford, cos from what I've been able to find so far, that block wasn't available until after they had sold it, or maybe they just fitted one they were testing that they had laying around to get rid of the car.Doubt it somehow.
I hate all this not knowing, I need stability
I met a guy here in Perth , and I've forgotten his name, but he seemed to think my car disappeared mid 1990's, and he really seemed to know his stuff, he has a Cossie too, but I was in a show parade and didn't have the chance to get his details.
I'f you are on here mate, contact me !!!!!
Cheers

The 200 was introduced with the 4wd Sierras. ALL 4wd Cosworths are 200 block.

keithscossie

Yes but when was the first 200 block that we can date put into a car ?
Thats what I would like to find out if poss?

keithscossie

Incidently Stu, I havent forgotten I owe you for the wrong water header tank ! When I get around to ordering the wasted spark kit, I'll square you up !

If the first 4bs were 90 or 91 it may be possible if your car is 86/7.Wouldnt worry about it seeing as the numbers match up.It does seem possible as it could of been done through/at Ford.
EDIT that was the time the public could purchase in prodution car ,Ford would of hands on them before that most probs.

That block would have been available whilst ford owned the car, the block was possiblely being designed not long after the launch of the 3dr.
I'd be curious to measure the head to see if it was new or skimmed as it could have been a complete new built engine using the famous ford parts bin
If the engine number matches the log book then its almost 100% ford put the motor in

keithscossie

I wont get too depressed till I get the chance on Tuesday to make sure the numbers are the real deal !

BRAMMER

Is their a problem with it being on a 200? i know sometimes it's nice to keep things original but to be completely honest the fact it has a 200 over a 205 isn't the end of the world - for all you know FMC could have used your car as a guinea pig fitting the 200 engine for some reason which in fact would be a nice little tale if you came to move the car on

my friend had a j plate 4x4 with a 205 block all numbers matched vin and reg doc.

was'nt the 500 block stamped 205 tho? if so could of been a 500 block in that one.

Paul_RS

iTrader: (4)

It can't have had a 205 block from factory though?

nicksaph

i have seen a 200block in a 2wd that is supposed to be "all original" the engine no. matched,
but it didn't look quite right and the yb no had been ground off so its not impossable that someone has changed it in the past and restamped the engine no.

R5FORD

iTrader: (1)

As above.. Could have been re stamped?

martysmartie

iTrader: (1)

Correct, YBJ was essentially an RS 500 (205) block.

As to OP so far as I know, all 2WD's were 205 block, as to answer your question 1990, thus the year of introduction of the 4x4, this is what the end digit denotes, so I would say you have another engine or block.

So, for example, '5' denotes 1985 which is when the block was revised, before this the block was just known as '20' which obviously denotes displacement.

Martin

carl/saff

Dont forget to check above the water pump at the front of the engine ......

You should have ;

YBJ ...... then the Sequence numbers = 4x4 saph early 90/91
YBG .... then the sequence numbers 4x4 saph late 91/92

I have more info on production dates ......just want everything to be correct if/before put into print .

All my numbers tally up and I have a j plate 4x4 with a 205 block fitted from factory although car build date is July 1990

cossieDavedree

Who cares whats more important is your block hasn't cracked yet, these pinto blocks are getting on a bit now !

Anyway I thought the Rs500 block was still a 205 block but had smaller core plugs, and the lug was machined off by the alternator mount?

martysmartie

iTrader: (1)

205 block by name but I think the block was cast differently, along with your mentioned core plug difference.

Mount was different as the alternator needed to be lower to accommodate the larger turbo.

Think the blocks were all the same, but cosworth selected the ones with the closest bore tolerances denoted by the numbers next to the distributor ie 2222

My mate had got hold of an old sierra to break and found the block to be the same (casting numbers etc) as his knackered cossy 205 block and used it to build up his new engine

martysmartie

iTrader: (1)

They are not! 2WD Cosworth blocks, are merely Pinto 205's that were hand picked for there bore tolerances, i.e. '2222' that you mentioned.

RS500 205 is a completely different casting and is a lot stronger than the "Pinto 205 block" (obviously had to be for the 500HP + they had in race trim) and has smaller core plugs, the same block is fitted in YBJ 4x4's.

Martin

Jasu

You mean that YBJ is same block than YBD?

martysmartie

iTrader: (1)

99% sure yes, YBJ incorporated a lot of RS500 style features.

Martin

keithscossie

OK got the numbers !
The block is marked YLB 1456
Any clues on that one guys.
The MOT cert from 7/4/94 says the engine number is GJ61651
But that is the last 7 characters of the chassis number as well.
Thanks
Keith

martysmartie

iTrader: (1)

Are you sure it's not "YBL"?

The last 7 characters of the chassis number are the engine number, and so should tally!

Martin

keithscossie

Well I haven't seen it for myself but 2 people have now read it and both say its YBL, I know its not the standard YLB so its even more confusing.
I'm off for a look tomorrow myself.

keithscossie

To make things worse Martin, if the chassis number and the engine number are the same then surely that would mean this is the original engine, but why is it a 200 block not a 205 ?
Jeez its too hard !!

2ndGear

iTrader: (2)

what about this then,
ive got a 2wd cossy with a 205 block in it and no core plug at that back and it has the extra webs of metal on just like the 200 block!!!!
i was told it was one of the first types they introduced

martysmartie

iTrader: (1)

Standard engine is "YBB", YBL was another type of engine but it seems a grey area as to what it actually means, I should think the block may have been replaced and that number added to it, perhaps?

Martin

keithscossie

I had a look today, Def says YLB, perhaps I should delve no further
I might not like what I find
Cheers

Simple the "L" stands for Long engine so no manifolds etc. It was built by cosworth for Ford after the YBB finished. They were built in the late 80's so are hybrid of 4x4 bits.

Probably done by Ford and would have been stamped by them when it went in I'd imagine.

carl/saff

Mine seeing a list agaes ago on all YB derived engines .....YBH ?

Was quite a few

keithscossie

I think some may be missing it, the block is stamped "YLB" NOT "YBL"
Thats the confusing bit.
I could understand if it was YBL that makes sense.
Anyway, should have the car back monday, will be nice to drive it again regardless of numbers!!

rsnissan

iTrader: (9)

I understand you have said "YLB"

Please see the pics below that's a BRAND NEW crate engine from Ford.

Notice the 4x4 cam cover (screw type oil cap) on a 2WD head(turbo damper fixing point)

and also the "YLB" clearly marked on the side of the crate.

As I said I think your engine is a spares engine swapped out at a later day, and most likely by Ford

keithscossie

Andy, excellent thanks !

No probs

Good luck with the car.
