Case 207 engine head gasket question

May not need to re-sleeve and little point in putting new gasket on if it needs remedial work first (or later). You have found the problem, so fix it now rather than the added expense of another gasket, more down-time and possible further damage to the engine.

1) Is the liner/piston serviceable otherwise?

2) If so, mark liner (for replacement in exactly same position as previous.

3) Remove liner and mark again on side (as previous mark may be removed).

4) Machine of top face just enough to remove pits.

5) Replace liner in exactly same orientation as previous but using shims to keep liner protrusion as specification.

6) Rebuild rest of top end.

Job done. Will work as long as metal removed from liner is not excessive - like removing most of the top ring on the liner! Just try to put everything back in same position (liner and piston ring gaps) if there is wear, or things may probably never bed in properly again.

hope this helps.

Because he will need to take it out anyway.

You wrote: "all that"

Skimming will only take a couple of minutes after setting up in the lathe. I would know how much the protusion was before removal, how much I had removed, so shim-stock thickness I needed to keep/get the correct protrusion.

The poster asked for an alternative. I gave him one.

Poster did not give an addy so I did not assume one - this is a world-wide web and not just a local chat shop just for those in the US.

I live in the UK and a sleeve would probably cost more than that in GBP.

If I were to change out the sleeve I would change out all of them if they showed appreciable wear.

My labour costs would be zilch as I don't charge myself.

I know not the condition of the engine bottom end either. This way you do not alter the conditions appreciably.

This is, in my view, already too much a 'throw away' society. So why just dump an otherwise perfect item?

So there are a few reasons for my post.

Want any more reasons? The guy can probably make up his own mind what he is going to do or he may choose to bury his head in the sand, just change out the head gasket and hope it doesn't fail again.
