Title: Cylinder Head Removal Pictures
Post by PJDavis on Dec 26th, 2010, 10:39am
Yesterday whilst the Gal was out visiting, and I was cooking the turkey, I whipped the Cylinder Head off the new 2.0ltr engine.   Now I'll be wanting Stuart to take the Block away!

First pic shows the Rocker-box in place.

The next pics show the rocker-box off, you can just see the Ten red topped Torx bolts, T55 right enough, and taking the face-plate away then removing the camshaft sprockets.   I didn't have the right tool for holding the sprockets, so just hit them swiftly anti-clockwise with the heal of my hand on the socket drive.

Before undoing the cylinder head bolts, don't forget to remove the three bolts at the front, you can see two of them in the first pic, the other one is hidden by the cam-chain follower.

Finally Head Off, and looking onto the new pistons still with their sizes noted.   I was quite surprised to find that my mate was right, the engine has never been started.

Someone feel free to move this to a more appropriate place, or just leave it if it's felt irrelevent.

Hope you didn't mess up the 'Axminster' !! ;D

Ha ha Simmo.   It actually IS an Axminster as well!   About 40 years old, tested through time :D

I was going to say, very clean in there! But if it's never been started, that would explain it ;D

Are you changing the block then?
Title: Re: Cylinder Head Removal Pictures
Post by PJDavis on Dec 26th, 2010, 3:04pm
Not changing the block.   It's a 2 litre and mines a 2.3, so I've taken the head off for keeping.   I got the engine a long time ago with the intention of using it in a kit-car I built. (A Spartan)   I built the Spartan in 1995 and managed to get a hold of a 2.8 Granada engine, so used it.   I've sort of offered the block to Stuart so I'm now going to be waiting till he comes North to collect it.

Thats definatly not a standard 2.0 :)

 What was it out of/for originaly ?
Title: Re: Cylinder Head Removal Pictures
Post by PJDavis on Dec 26th, 2010, 4:56pm
Can't really say where I got it from.   I understood it was just an ordinary 2.0 litre engine, hadn't ever bothered to check otherwise.   I got the automatic 2.8 for my kit-car from the same source, and it was a flying machine, my Brother-in-Law had a Capri 280 Brooklands at the time, and my Auto Spartan was quite noticeably faster.   Incidently this 2.0 litre is a manual and had a brand-new clutch on it, it's a bit surface-rusty, but if anyone is stuck!

Looking at those Pistons they look flat toped where all the Scorpio 2.0's i have had apart have dished pistons that looks more like RS2000 spec as they are higher compression   .  

Whats the engine code stamped under the engine number ?

I've just had a good look at the engine block.   On the front facing front is HCA000 6XY....then four numbers.   On the near-side of the block on a riveted small plate 03J93.   On the off-side of the block BM89  C97KM.

Post by Stixy on Dec 27th, 2010, 4:17pm
I am not sure about those numbers ?

This is a Scorpio 2.0

This engine is the higher compression  Sierra / Granada / RS2000

Your pistons are different to both ?
Title: Re: Cylinder Head Removal Pictures
Post by PJDavis on Dec 27th, 2010, 5:40pm
I haven't yet checked thoroughly, and I wasn't going to bother my bum, but I think the pistons are maybe of a 'different' material.   See, now I might have to pop one out to check!   How do those bore measurements in my pics tie-up?

The 16v 2lt has an 86mm bore,the 2.3 has 89.6mm flat topped pistons a la your picture,are you sure there are no balance shafts in the bottom of that engine ?

Isn't that red writing on the piston top indicating 89.6 as Gozz says?.

Sure is Simmo.   But the block doesn't have the same look about it at the front that my 2.3 has.
I understood that the 'flat-front' indicated a 2.0?   I'll need to turn it up and take the sump off, and perhaps that black plate on the front to see if there is a balance shaft.   Pictures will be taken and posted up.

OK.   After a wee bit of 'tapping' to get the pulley off, (I don't have a puller at home) just kept tapping it with a copper/hide mallet and prising with my fingers on the opposite side.   I then took the black plate off and the pics are below.   So, someone tell me.   It looks like it was manufactured in 1993, which would fit well because I started my kit-car in 1994.

Course the blasted problem now is:   I let the cam-chain slip off the lower sprocket, so I'll need to find out how those blue marks and rust marks line up if I put it back together.   It's clear though that the engine is new, which I didn't think it was when I got it.

Looks like a 2.3 with the ballance shafts but as you say the block looks like a 2.0 without the webbing and the dates dont add up  either from what i have seen the 2.3 came out mid P reg 1996  also i have never seen a 2.3 with an oil cooler .

Every 2.3 i have striped has had the oil pump presure relif valve ( 8 o' clock position on pump )  unscrewed until it touches the block and yours hasnt  :)

I don't know whether or not a 2lt block could be used with a balance shaft housing and 2.3 sump added,obviously you have 2.3 pistons,I don't suppose it would be beyond the bounds of possibility to bore one out as there is only 3.6mm difference.You could deduce the type of crank in that engine by measuring the stroke,the 2.0lt has 86mm,and the 2.3 91mm.As Stixy says,the front of the block casting on the 2.3 has three ribs above the timing cover.
Yours is without doubt an oddment.Regarding the timing of the cams,you use the gold links over the mark on the crank sprocket,and the marks on the cam sprockets for a positive setting,you would need a new tensioner for the top chain,as once they have extended they cannot be recompressed,the balance shafts have their own timing marks on their gears,if the housing is left in situ this will remain set.

you probiley have a mule engine that cosworth made up when converting the 2.0 to 2.3 .but never run on a test rig .its a rwd engine with a long front puley .can you  post a picture of right side to see whear the mouts are  
Title: Re: Cylinder Head Removal Pictures
Post by Stixy on Dec 28th, 2010, 9:15pm
The ballance shafts are timed together but still need to be timed to the crank . If you look at the pic there are 2 blue spots of paint one lines up with the crank dot and the other lines up with a dot on the main ballance sprocket . The paint dots explain why there are no timing marks on engines i have striped  i had to buy a new chain with coppered links and mark the old chain in the same positions to set it all up :).

As for fitting ballace shafts to a 2.0 its possible if you cut the part of the cylinder block off the 2.0 at the lower part of the timing cover also an oil way would need to be drilled to feed the shafts .
As Gozz says the tensioner will need replacing  they can be re set but i wouldnt risk it myself for the sake of £30 .

Have you got any more pictures of the sides of the engine ?

was it a multilayer head gasket ? was there a part number stamped into it ?
Title: Re: Cylinder Head Removal Pictures
Post by gozz on Dec 28th, 2010, 11:11pm
The secondary chain for the oil pump and balance shafts is still in situ on this engine,therefore the balance shafts are still in time.

I have just taken pics of the sides of the engine.  
But because of other reasons I am unable to post pictures of it.
The gasket is a three layer gasket, with an outer layer of black gasket on both sides of a thin Stainless Steel inner.   The number on the gasket is: 96XM605TA3BTC.. then another faded letter.
