Loose cylinder liner

[sprint]

In the process of doing a strip and rebuild of my A4. Have the barrels off and have noticed that I can push the No 1 liner in and out by hand?

Is this a common problem with these engines?

Was planing to smear some Loctite bearing around the sleeve and push it in again, is that OK and best thing to do?

i would coat it in three bond that way it will be sealed from oil working its way between the liner & the barrel. the head will stop it moving once it is fitted in place

Thanks.

Have never heard of three bond? Is there a specific type/version I need?

Loose liners are common.
Shouldn't cause too much bother as the liner can't move once the heads bolted on.
You should be able to buy liner bond from a local engine reconditioners or online etc.

Let me tell you of a stupid thing I once did. Fitted new liners. I noticed that they were all protruding about five thou. Not to worry I thought!
The head gasket will effect a better seal when the head is pulled down.

What did I forget.....?
Sure it effected a better seal around the liner tops, however, it did not effect a seal on the four corners of the block.. where the oil comes thru to the head.
Stupid mistake!
