После полного разбора и осмотра, было принято решение сделать для начала замер цилиндров, поршней, колена, а дальше уже решать, что делать.

Итог осмотра:
Хон на цилиндрах сохранился, но рукой ощущается небольшая неровность цилиндров.
Кольца в поршнях зилипшие.
Выработка на вкладышах коренных.
Выработка на вкладышах шатунных.
Огромный нагар на клапанах.
Пропускающие маслосъёмные колпачки.
Большая выработка на обоих балансировочных валах и соответственно вкладышах.
Грязные гидрики.
Отвёз на промерку блок, колено, ГБЦ.

Результат промерки:

В цилиндрах есть небольшой эллипс. Но судя по «Камасутре» в пределах допуска. Расточка не требуется на этот раз.

Поршни сточенные. Требуется замена.

У ГБЦ в сервисе не стали мерить плоскость, сразу шлифанули. Рассчитался конечно, но больше туда не ногой, такие мастера мне не нравиться…

Колено промерили при мне и было принято решение точить на следующий (для коренных последний, для шатунных предпоследний) размер.

Балансировочные валы под замену.

Клапана очистить и попробовать притереть.

Гидрики попробовать промыть, почистить.

Приблизительные подсчёт вынес вердикт, что дешевле своими руками откапиталить. Своими руками не потому что разбираюсь и не раз это уже делал, а потому что в нашей «деревне» мастеров по нашим двигателями нету.

Ну а теперь к самому ремонту.
Начал с ГБЦ.
ГБЦ всю очистил. В сервисе, как выше писал, шлифанули.
Прочистил гидрики.
Чистил по инструкции с форума — mmc-chariot.ru/index.php/topic, 4881.msg172114.html#msg172114
По итогу, способ хороший, гидрики оживают. Но если колечко, удерживающее поршень, не держится, меняйте гидрик. Я не поменял, теперь единственный периодически стучит.
Клапана притёр. Заменил маслосъёмные колпачки.
Распреды не трогал вообще. Честно даже не мерил.
Но выработки не было нигде, не в постели, не на распредах.

Дальше дело дошло до блока.
Цилиндры не точились.
С помощью промерки посадочных мест под кольца в поршнях, было установлено, что за поршня. Поршни были установлены от vvt-i мотора. На такие поршни кольца не найдёшь по адекватной цене, да и поршни для замены тоже не найти, только с разбора. По итогу решил купить родные (по году) поршни с разбора, и комплект колец по адекватной цене.

Так же разница ощущается и по весу. Vvt-i более лёгкие и меньше…
Посоветовавшись с одноклубником.
(Кстати спасибо ему огромное за советы!)
Принял решение увеличить диаметр отверстий для отведения масла, под маслосъёмными кольцами.
Стандартный диаметр 2,2 мм. увеличил до 2,8 мм.
Результат:

По идее, увеличение диаметра этих отверстий, должно увеличить время залипания колец.
Кольца стандартные.

Балансировочные валы были удалены.
Небольшая инструкция:
Один вал просто убирается, удаляется сальник со втулкой и заваривается отверстие.

Второй приходиться отрезать, заваривать масленное отверстие, которое было в вале.

Так же надо достать один из вкладышей и перевернуть на 180 градусов, что бы перекрыть масленное отверстие.

Колено выше писал.

Настало время сборки всего воедино.

Preface

This manual is specially made for those who

engage in automobile maintenance and repairing.

Following general rules of system division of vehicles

(engine, clutch, etc.), this manual adopts the division

methods by major assembly. In order to describe all

parts belonging to an assembly, assemblies are further

divided into several parts.

Brief introductions, specifications, main points

of adjustments, mounting and dismounting,

assembling and disassembling of the assembly

components are covered in this manual. On the top of

the first page of all assemblies are the content, through

which the needed information can be easily found.

All explanations and specifications in this

manual is the latest till the date of printing.

Sealant (FIPG)

Sealant is used on many parts of the engine and gearbox. The using of sealant is for the purpose of adequately sealing,

therefore, much attention should be paid to the dosage, position and the surface of sealant. Insufficient dosage of sealant

may result in leakage, while superfluous dosage of sealant may result in the overflow of sealant and jam the passage of

water or oil, or narrow the passage. So, in order to avoid leaking on the mounting surface, it is absolutely necessary to

keep the correct dosage that may keep from disconnection.

FIPG used in the engine is of Room Temperature Vulcanizing (RTV) and is provided in the way of 100-gram tube (Piece

No. MD970389, for engine use). RTV may vulcanize after reaction with the water content in the air; therefore, it is usually

used on the metal end face.

Disassembly

Components assembled with sealant may be disassembled without using a special method. However, in some cases, it

is necessary to lightly hit the components with a mallet or similar tools so as to break sealant on the coupling face, or

use a smooth thin sealant knife to hit into the joint face gently without damaging the coupling face. When dismounting

the engine oil pan, use special tool for dismounting oil pan (MD998727).

Cleaning of Sealing Surfaces

Remove rubbish on the sealing surface with a sealant knife or a steel wire brush. Be sure the sealing surface is flat and

smooth, and there isn

t any oil stain of foreign object on it. Remember to remove the sealant inside the mounting hole

and the threaded holes.

Essentials for Smearing

Matters to be taken into consideration while assembling components with FIPG.

Smear sealant equally within the prescribed diameter to cover around the mounting hole. Sealant that is not yet vulcanized

can be removed. After the installation, the sealant should be sufficiently vulcanized (approximately 1 hour or so). Do

not apply oil on the smeared part or wet or startup the engine during this period.
