Hello, I've just bought a fully recon'd short block from a company in newark. It's got new pistons, shells, camshaft bearings etc and bored from 1600 to 1640, and fully balanced conrod and crank. I noticed however that it has wet-liners inserted :- is that a problem? (I just paid £600 for it with a stage 2 Unl head)
Seems strange that its linered at 1640cc
i'd guess that someone tried to bore it to 1700+ it didn't work so linered it and sold it as 1640.
How many cylinders are lined?
No experience of any of this but internet wisdom suggests more than one cylinder lined isn't good due to reduced strength in the block.
You won't have a problem. Many Formula Ford 1600 race engines are linered back down to 1600 as virgin blocks are virtually unobtainable.
An added benefit is that the liner material is probably of a better quality and less porous than the original casting.
BTW are you sure you mean WET liners? They should be dry. Wet liners are generally used in an alloy block, and are clamped in place by the cylinder
head.
I just phoned the engine shop, who said they are dry liners, not wet liners. The previous owner would have used the liners to reduce it back down to 1600, and that the steel liners are stronger than the original cast anyway, and there is no chance of water leaking into the oil. thanks fellas.
It'll be something from Newark Engines? A company not connected with me.
The liners will be cast iron - not steel!
MikeR - if you don't know what you are talking about, why post such rubbish? Just re-read what you have written. Why try and mislead forum users
in this way?
Memphis Twin - sensible and accurate reply
Hi Dave, I can see the liners from underneath and it looks way too thin to be cast - can you take a look at this photo and let me know?

Yes, they will be cast iron liners. They are readily available for block reclamation work. As a rule of thumb you are generally OK machining them down
to a section of about 1.5mm.
The only steel liners that I am aware of are the very thin type (0.5mm?)sometimes fitted in Jap diesel engines such as Isuzu.
In the last two weeks I have reclaimed two F3 Toyota Blocks and one Lotus T.Cam Block for customers in this way. There's a procedure to follow
and you need decent and appropriate equipment to do the job but it's not rocket science.
All good FF1600 blocks are linered (better material than parent block). I understand that the going rate for a freshly linered 711M, 1600 block,
decked and with crank journals honed is about £600.
Not and advert, and my prices are similar to most, but I charge £80 per bore. Just as apoint of information.
They will be cast iron. The liners are fully supported by the block so they don't need to be thick. Wet liners, however, are not always fully
supported and tend to be thicker. If you think that they are too thin ask yourself what piston rings are made of.
Slow typing.

£600 is on par with what I've just paid for it, but to be honest, I didn't really know what I was buying - it looked shiny :-) LOL
