Better off sourcing a decent block John, the 1400 ones are generally better, then drilling and tapping the oil drain for the turbo.
Once annealed, the blocks are basically scrap, and shimming the liners is a temporary bodge Brian |

Rain stopped play ... AGAIN.
Made a start by jacking up the car. When I fitted a new Cylinder Head Gasket to this car four years ago, I also fitted better quality Exhaust Manifold Studs, Nuts and washers. The Studs have an Allen Key facility which makes working on these areas so much more convenient and easier. |

Quickly had the Coil Packs and Camshaft Cover removed
Even the Gasket was in good shape. When the engine over heated I half expected it to have destroyed the paint surfaces as sometimes happens even in a healthy engine. Small traces of Water-Oil Mix. Condensation or?... Also removed the two Retaining Bolts and Nuts to release the Alternator. I actually swung it forward to facilitate Cylinder Head and Exhaust Manifold access and removal. Having done that, turned my attention to the 5 Exhaust Manifold Nuts, Washers and Studs. Four years ago I treated this engine to a set of Stainless Steel, Allen Key Drive Ex-Manifold Studs, Brass Nuts and Washers and using these Allen Key Tools they were soon removed. Here's the tools for the job. Both useful because of various positions needed and other access restrictions. Tools in action End Product ~ One detached Exhaust Manifold. I carefully recovered the Exhaust Manifold Stainless Steel Gasket. It looks like new. So will reuse. |

Do the liners drop because of heat or because of the hammering effect ?
I was told that the head suffers after overheating which causes the liners to hammer up and down and that the block itself doesn't really suffer from the heat. Pete. |

I suspect one or both can play a part here depending on severity of excess heat. Only needs a slight weakening and enlargement of the Liner Location and that enables one or both the above scenarios. The basically very similar MG6 1.8T engine ( Chinese version of Rover's K-Series ) I have been informed by someone when they worked for the Chinese operation at Longbridge, that the Chinese use a FORCED not GRAVITY fed casting process for those major engine components, the Cylinder Block and Cylinder Head. This must result in a stronger structure. When fitting the MG6 engine to one of my MG ZT-T 1.8Ts, there were a range of improvements clear to be seen. At the time the real improvement was unseen. That of the superior casting process. There is a possibility of all my work being a waste of time. I will do it to the best of my caring ability with the benefit of not having a profit or time gun held to my head as is all too often the case in the pro-environment repair shop. By being thorough and taking my time ( no pressure to have car ready for journey to work tomorrow ) a competent repair should be the end result. If after all that, it does not work out, no real harm done. It's mainly a learning experience for me which I enjoy. By the way there is more than one example of MG6s with high mileages ( 200,000 mile plus ) one a Taxi, never needing much engine work at all, just regular servicing. Few Rover K-Series 1.8s can claim that. My 1.8 ZS bought new in 2003 now with 100,000 miles on it still no CHG issues... fingers crossed. I did catch a totally worn out Water Pump which if not spotted, would lead to cylinder head gasket DAMAGE on my MG ZS, which far too many confuse with failure both within the trade ( often conveniently for them ) and car consumer circles. Sunny now so out with the tools soon. More progress today. Some updates later today may follow if of interest. |

I thought the Longbridge casting were vacuum cast not gravity !
