Hi everyone, just finally got the front head off my 156 2.5, was hoping to change the gasket. Unfortunately, my worst fears came true, when I found a massive crack in one of the liners!
I realise to change this, sump will have to come off, piston/con rod will have to come out, liner out, new liner with new seal in, and piston back in. However, eLearn chooses to skimp over this whole changing liner area. It appears I can remove the sump without removing the engine, and I was wondering does anyone here actually know anything about changing liners? as my first question is:
1) Can the liner be changed without removing engine.
2) How is the liner sealed at the bottom, and is this a DIY job.
3) Im guessing I will also need new piston rings?
4) How common is this with Alfa's, and could it have been caused by a hard drive for about 30 miles, or would this have been building up over a while?
5) If I was to send it to a shop (just to have one liner done), any idea of approximate costings?
6) If I'm gonna put in this much effort why not scrap it / convert to 3.8?
7) Any idea of rough pricing to obtain following equipment required for 3.8; 6x liners, 6x pistons, 6x con rods, mods to block to allow liners inside, and does the head gasket need to be replaced, and how are the liners sealed top and bottom.?
