Engine rebuild, The reassembly started ! Options

[Valy]

I got a spare engine with my car. The engine looks nice but the PO drained the oil out and left the sump open. Then he wrapped it in plastic wrap and dropped the engine on the left head so it has a nice crack.
Got myself a new pair of heads that are rebuilt right now.

It's going to be a big L-Jet as I don't have the patience to deal with the old D-Jet (although I have all the parts for a D-Jet). I
I'm going to make it a 2056cc unless in change my mind and go crazy with a bigger crank (IMG:style_emoticons/default/idea.gif)

I started taking the engine apart and going to document as much as I can.

Not my first rebuild but is my first Type4 rebuild so wish me luck!

Today I got pistons 3 & 4 out.

#3 looks nice, not too much signs of wear. The ring gaps are about 1mm (trash)
#4 is also nice but the piston got a small bent while trying to remove the pin. That bent trapped the oil ring. Never mind, I'm going for bigger one anyway.

The cylinder registers are nice. In fact, the entire case is very nice and clean.

Anyone knows the meaning of the inscriptions on the cylinders and pistons?

The thermo-time switch was moved towards the flywheel on later cars. On 1.7 engines (IIRC) the TTS was on one of the M8 case parting line bolts. On 2.0 engines (73&74) the TTS is on the air plenum. On 1.8 engines (and possible later 2.0s) the TTS is on a bracket on the rear tin screw we're talking about bolted with an M8, but I thought it was M8x1.25.

Since yours is a bus case, and it doesn't look like it has the second oil relief piston, I would say that case was an L-Jet T4 bus and the hole was original (I suspect the early carb'd T4 busses would have M6).
