1.6d to 1y the definitive guide

Postby weldore » 15 Aug 2012, 16:05

theres been a few people over the years gone this route including myself and have had to ask questions or trawl through the alt forum for answers and i was thinking what if all of us who had done it joined together to make a sticky .

we could use this thread to get it together as one large article and then submit it as a sticky up top...anyone want to contribute ?

That is a brilliant idea ,I recently wanted to get info on a 1y pump and could not believe how disjointed all the information was? And the search won't let you just type in 1y as it is not enough letters.

I would start the thread with a list of all the possible donor cars and the pitfalls ie Seats having Lucas pumps.

i was thinking of just getting into the basic change over and how to do it right to begin with..list the parts that are needed and where to get them from.i know its info that could be found on many of the engine swap threads but if it were in one place it would help and many questions wont be asked over and over again

Re: 1.6d to 1y the definitive guide

Postby weldore » 16 Aug 2012, 18:10

some good links there mate :ok

so i was thinking today about how to present it and thought maybe do it something like this


1. Introduction to the 1Y engine

If you have a tired or broken 1.6d (cs)or 1.7d (ky) and have decided its time to replace then the best option is to replace it with the same code engine.There begins the problem of finding one of these in good condition and maybe an alternative solution would be to fit a slightly newer ,slightly more powerful engine.
The 1Y engine was put into various vehicles around the early 1990's and is a 1.9 litre diesel engine.It is almost identical visually to the 1.6 and 1.7 earlier versions and gives around a 15 to 20 % increase in power to the 1.6d.Its not a massive amount of extra power but you will notice the difference after driving the 1.6.
Insurance wise it will cost more or less the same as the 1.6d and 1.7d depending on your insurer and if it were to be more its worth the extra to be able to pull away at a more modern paced driving style and hill climbing will also be improved.
The mpg will be the same as the old engines that were reported to deliver around 35 mpg
The only draw back will be the gearbox as you will find you will get to 60 mph a lot faster than you did with the 1.6 and have power to go faster but will be held back by the gear ratio (on most standard gearbox's)

In the opinion of all who have done this conversion it is very much worth doing and maybe at a later date sort out the gearing to accommodate the new found power ,this could be as simple as larger diameter tyres or a better ratio box.

The swap over is fairly easy to do and you will be using parts from your old engine in place of the 1Y ones,infact around 80% of the stuff is already on your old engine ,the rest you will need to purchase.

-----------------------------------------

2. Finding a 1Y

Start looking on the internet for a car that has ended its life due to anything other than engine failure.With the engine being introduced early 1990's and stopped being used late 1990's your looking at a vehicle thats going to be atleast 12 years old.If you can find one in a car thats running with a bit of tax and mot then that is the ideal engine, you can hear it running and perhaps use the car for a short time to make sure its engine is worth using.

Another way would be to buy an engine already on a pallet ready to be delivered, normally theres around a £50 charge for delivery anywhere in the uk.The only thing you need to be asking about this is a 'turn key engine',this implies that you have everything on the lump to make it work.If you decide to keep the old water pump and alternator set up from the original engine then it wont matter if they are missing but the key thing to make sure of is if it has the diesel pump included.You dont really need any of the manifolds either as you'll be using the ones from your t25 engine.

and lastly but not reccommended is to buy one from a breakers.only buy it if you can hear it running.


ok so what cars have these engines installed from factory..

vw --- mk3 golf ,caddy

seat --- inca van , ibiza , toledo

-------------------------------------------



3. Preparing the 1Y

The very minimum you will need for the swap...

a fresh can of oil
an oil filter
a new sump gasket
a spigot bearing
some gasket sealant


It would be best to get this on an engine hoist but not necessary.

So you have the 1y engine sat infront of you ,it might be a good idea to degrease/clean the engine before you start.
Shove cloths or paper in any holes that dont want water getting in them .

Things to remove and wont be needed anymore...

All the electrical connections and all the housings for the coolant pipework
two behind the head ,one on the front of the head and the one from the bottom of the water pump.

also..

the engine mount arms
the power steering pump
the sump and then the oil pump strainer(at this point you can drift out the dipstick tube from insidee
if you want to use the one from the 1.6)

the inlet manifold (keep the gasket)
the exhaust manifold (keep the gasket)
the clutch
the flywheel

-------------------------------------------

4. Removing the old engine

5. Transfering parts from the old engine to the 1y

Alternator belt setup.

One option available when transplanting a complete 1Y is to keep the alternator and water pump that came with the engine. The noticeable difference here being the different belt setup. The 1Y has the ribbed belt whilst the original is a V belt.
Advantages of doing this include saving a bit of time, (I found taking the alternator bracket off a bit tricky and ha to buy a new extension for my socket wrench) enjoying the self adjustment feature (spring loaded) of the 1Y alternator and possibly ending up with a newer more powerful alternator.
Disadvantages are the wiring setup is different between the two setups - so you are going to have to work this out (note to Weldore - maybe someone could supply this missing information).(ringo..ill have a look later at what i did..proberbly not the neatest way but it worked)


6. Installing the 1y

7. Maintenance of the engine


anyone want to pick a number and type away :mrgreen:

Not really that sums it up well, I think the power thing seems more than 10% but that is probably because most 1.6 are knackerd by the time you change them?
