Well, After taking the head off my Mk2 S found the following "groovy cylinder". Looks so neat and tidy it almost seems that it was there from new...... Would anyone have any idea of the cause of this? Guess a full rebuild on the cards....credit cards that is....

Mate if your rods are press-fit on the small end then they are probably stretched oversize hence the reason your pin has moved. Sorry but not only do you need a new block but a new set of rods too. G. |

Yes it might be able to be saved, as mentioned above you might be able to re-sleeve (or re-line) the block, you'd have to get it checked out |

Depending what the bore size is now, boring that cylinder and fitting a liner should fix the bore. But the piston will be trash too. |

yes definately a gudgeon pin move,,, but i`d bet the rod is bent from possibly6 a previous head gasket blow, hydraulic locked (filled with water over night & tried to start it in the morning type thing) & bent the rod in the process (just a tad) once a rod is bent it will tend to allow the gudgeon pin to wander "down-hill" & score the bore i`ve seen them on both sides of the bore in some cases where (obviously) the rod has just lost all will to stay straight & is then all "wobbly" (for want of a better description,,, maybe "Jelly" would be a better word  anyways, very typical of a bent rod... sorry to say, but yes probly be able to fix with a sleave job not cheap but might get away with just the one sleave

Thanks guys, Good chance to get the engine checked and also to get the engine bay cleaned up and painted, as (beside this problem and the crappy engine paint job) the car looks great and is rust-free...... "Always look on the brighter side of life.........."

In the olden days it was common practice to braze the score up and re-machine They called them Tram Tracks |

Good news, Just got an email from the great GR himself, and it can be saved! Looks like I am going to get even more experience (and skinned knuckles) doing an engine removal. Luckily I have the help of the Ausminiers who have contributed their experience and hard won knowledge to make it easier than just following a 40 year old Scientific publications book which I still have from my first Cooper S....... All good.....

Well, Just fitted the towbar to my car so I can go and borrow an engine hoist so I can take the engine out and take it on the trailer to get fixed.......the work is multiplying! What would be the best way to lift the engine as the head is off - so can't use the head stud attachment method. Safe to sling it with some ratchet tie-down straps? Any easy safe way that anyone could recommend? Thanks in advance. |
