Hi All
Was given a 2 litre engine a couple a weeks ago and was told it had 65K miles on it and looking at it I believe it.
Took head off today to clean it up and it`s very clean ,but noticed that 3 out of 4 pistons "rock" a little bit from side to side ! Surely that means rings are stucked. Now would it not be sensible to put new rings in it now that`s in pieces ?
Thanks

The old chestnut again. What do you do? Once you start you usually end up doing a full rebuild.

The other alternative although it's too late now is to change the oil and cam belt, make sure it turns over freely and start it up. If it start, runs well and seems a good runner just use it. If there are problems then you fix them.

The latter is the approach I usually take.....

Engines out........
Remove the sump 20min
Remove the pump 5min
undo one big end cap ......pop the piston out 10min......there done.
Check the big end bearings on condition and crank as the others come out.
If bearings are good,you can re-use or slip new ones in.
Do not disturb bearings and remove from rod or cap if you re-use.
Re hone pots and slip new rings on.(check your piston size)to get correct rings.
Don't forget ring gap is ok.
You can do this with leaving front pully on and flywheel.
I think a little rock is fine unless its a race engine.
If i lived nearby,i would do it for you in afew hours,but you have to scrap
the gaskets  Grin
If you do this,you could fit a little washer under releaf valve
spring on pump for that little better pressure(suggest you give to someone that
knows,if you don't).Will not hurt.
Not a full re-build,but a wise thing maybe while out.
Good luck.

Will take out pistons and put in new rings at least . Check the rest  Wink and what also came with engine was a brand new
oil pump NOS fiat stamp and fiat box - would that need the washer trick as well ? The head will go to machine shop for

Hi All
Just taken the flywheel off to send it away for skimming and found out that bearing for gearbox shaft is not working !
A quick measure says OD 35mm ID 14.7mm width 14mm is that correct ? shaft on gearbox is ID 15mm
Anybody got the correct size ?
Thanks

Do you mean the bearing at the back of the crank where the gearbox shaft end goes into?
