Title: Piston removal Post by leewar on Mar 28th, 2012, 10:25pm Hi All, As in fitting head gasket to a 2.0L, is it possible to remove a piston from the bottom of the engine while in situ, removing the sump ???If not, I've lost another scorpio :( Cheers Lee |

Title: Re: Piston removal Post by gozz on Mar 28th, 2012, 11:05pm Lee. What's going on then ? you can't readily remove the sump in situ,the pistons don't come past the crank,they must come up :( GOZZ. |

Title: Re: Piston removal Post by Simmo on Mar 29th, 2012, 7:02am Gozz. If you look at Lee's other post re the head gasket I think the info you want is there. ;) Now it's here!. Hi All, With the info on here and the advice given, I managed to remove the head, inlet manifold still attached, and found that all is not well. The gasket had definitely gone, between pots 2 and 3, the third piston at BDC and with about half an inch of water sitting in it. Once I had removed the water, I noticed that the piston head had been eaten, about half an inch missing. No scoring noticeable so maybe could be worse. So I have a question!! Can the sump be removed, partly or fully, so the piston can be removed from the bottom? I ask this because I can't remove the engine block. If the answer is no, then I am about to lose another beloved scorpio Thanks in advance. Lee ;D |

Title: Re: Piston removal Post by Scorpio_Mike on Mar 29th, 2012, 7:23am Engine out job I'm afraid :( Why can't you remove the block ? |

Title: Re: Piston removal Post by leewar on Mar 29th, 2012, 8:34am Hi Mike and Mike, Firstly, dont have the equipment, the space. I do have the time but for monetary reasons it might not be worth it! Head gasket and bolts already purchased, (quite cheaply before finding out I had a problem), but would still need lifting gear, new piston head, oil, antifreeze, tensioner plunger etc. Hi Gozz, Yes I knew the pistons have to be removed from the top but wanted to know if they can be removed with the block in situ :) Lee |

Title: Re: Piston removal Post by martin_rowe on Mar 29th, 2012, 8:52am Yes piston can be removed, easy job to drop the front s/frame down, support engine, disconnect steering u/j, disconnect engine mtgs, then remove bolts from s/frame. Will give access to bottom of engine. |

Title: Re: Piston removal Post by gozz on Mar 29th, 2012, 9:01am As easy as that eh Martin ;D Perhaps for you and I ;) |

Title: Re: Piston removal Post by leewar on Mar 29th, 2012, 12:35pm Martin, Will attempt anything. Is it possible for you to write down a comprehensive agenda of what to do, when, how and what with? Cheers Lee |

Title: Re: Piston removal Post by Matt on Mar 29th, 2012, 12:52pm Thats the same way i drop engines out by dopping the subframe cross member at the back off 4 large bolts in the sub frame the you can either drop the wish boned off or undo the top mounts some beefy chunks of wood accross yhe inner edge of the wings and some good rope arount the engine and undo the engine mounts and steering uj and lowet it down on a jack as your leavimg engine in try and get a axel stand under the bell housing help hold it up |

Title: Re: Piston removal Post by leewar on Mar 29th, 2012, 6:10pm Matt, thanks for that. I wish I understood all of it ??? Diagrams maybe!! Instructions for a complete novice would help ie step by step would be great. Cheers Lee |

Title: Re: Piston removal Post by leewar on Mar 30th, 2012, 10:35am Anyone with a detailed step by step would be great ;) Cheers Lee |

Think I've covered prety much all of it above, start with the car as high as you can get it on a pair of axle stands, the frame will drop down far enough to get the sump off & allow you to undo big end bolts. |

Title: Re: Piston removal Post by 5stud on Mar 30th, 2012, 12:00pm before you go to fare if you intend to use a new piston find out the cost avalabilety.when i inquird ten years ago they whear well over £100 each then |

Title: Re: Piston removal Post by leewar on Apr 2nd, 2012, 10:43pm Looking for a piston if anyone has one spare :) |
||

Title: Re: Piston removal Post by Mike H on Apr 3rd, 2012, 1:30pm So what Lee wants to do is get sump off to undo big-end bolts, then piston can come out the top. Which, apparently, it can only do anyway. How did the piston crown damage occur? And how deep is it actually? |
||
|
Title: Re: Piston removal Post by leewar on Apr 3rd, 2012, 1:49pm Mike, A good bit of the top edge has just been "eaten" away, with a little bit of depth, when the car broke down on the A12. :-[ It looks like the gasket went between two and three. When the head was removed number three had about half an inch of water in it!! |

Title: Re: Piston removal Post by Mike H on Apr 3rd, 2012, 4:09pm Interesting - broke off due to water pressure? (hydraulic lock). no signs of the missing bits? |

Title: Re: Piston removal Post by Matt on Apr 3rd, 2012, 5:55pm Check the coils and injectors its been pinking by the sound of it and thats whats done the gasket |

Title: Re: Piston removal Post by Mike H on Apr 5th, 2012, 8:21pm Ah that rings a bell ~ was it? Pinking.... |

Title: Re: Piston removal Post by leewar on Apr 6th, 2012, 12:41pm Not when is was driving before it broke down and blew a gasket!!!!! :) |

Title: Re: Piston removal Post by Stixy on Apr 6th, 2012, 10:17pm Whats the cylinder wall like ? any damage or scoring |
||
|
Title: Re: Piston removal Post by leewar on Apr 7th, 2012, 11:26am Does not look like there is any scoring or damage. Had a mechanic mate look at it and he reckons it was quite lucky that there was no more damage other than the piston :) |

Title: Re: Piston removal Post by Matt on Apr 8th, 2012, 6:03pm any marks on the cylinder head of that cylinder? im still convinced its been pinking to of caused that, the water hasnt been in there long enough to eat the pistion that much and it would of pitted the cylinder bore also pics of engine out http://i1219.photobucket.com/albums/dd429/Matt24v/Scorpio%20Related/P1517_19-07-09.jpg[/img] http://i1219.photobucket.com/albums/dd429/Matt24v/Scorpio%20Related/Photo-0015.jpg[/img] http://i1219.photobucket.com/albums/dd429/Matt24v/Scorpio%20Related/Photo-00162.jpg[/img] I have edited the post due to the pictures being TOO big for the site ( Should be no more that 640x480) |

Title: Re: Piston removal Post by leewar on May 16th, 2012, 10:23am Hi All, Matt kindly PM'd me the instructions to remove the subframe so I could get access to the sump for removal. Subframe dropped successfully and all the bolts removed from the sump including the four bolts on the bell housing but the d**n thing won't come off >:( It won't slide out or drop off!! Help because I can't see what's holding it if anything. Thanks Lee |

Title: Re: Piston removal Post by Matt on May 16th, 2012, 11:23am hiya lee http://www.fordscorpio.co.uk/manual/engines/dohc16v/DOHC16VDismant.pdf instruction 32, says it should just come off downwards its it lose one end? or does it seem like its still fixed solid could just be sealant, give it a tap with a rubber mallet or hide hammer |

Title: Re: Piston removal Post by leewar on May 17th, 2012, 8:45am Thanks for the link Matt but it shows the removal with the engine out. The sump is stuck at the bell housing, it drops down at the front!! Theres a thin metal type plate between the sump and the bell housing and the sump cover itself protrudes about half an inch into the housing. It's not a removal of the box is it :( |
||
|
Title: Re: Piston removal Post by Matt on May 17th, 2012, 9:42am Hiya Lee The thinn plate is just a dirt cover to protect the flywheel / drive plate. i cant see another bolt being there however a quick look at the 2.3 manual shows a location dowl on the rear corner, it could be stuck on this, try twisting and pulling at the same time, or a prybar reading further down the 2.0 maunal theres an allignment opperation, it could be stuck with excessive sealant |

Title: Re: Piston removal Post by Mike H on May 18th, 2012, 4:08pm How we getting on with this? Lee certainly seems to be unlucky with his cars (the 1st one having pranged on black ice) :( |

Title: Re: Piston removal Post by leewar on May 18th, 2012, 9:27pm Mike, been busy the last few days but will attempt to get the sump off to access the pistons ealy next week :) |
