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 lowermost pic of the oil pump shows a failing pump.. See that idler gear shaft?? Its become loosened in the body and is waiting to contact the camshaft. This is a common problem with stock pumps and the reason why I haven't used one in over 15 years. Once you lose an engine to that occurrence; you learn the lesson really quick.

I can see wear on the camshaft gear but the oil idle gear shaft seems to be fixed in place. I don't know how it should look like so I took an other picture to show it from the side.
I also measured it and it seems to be about 0.5mm away from the camshaft, unless the camshaft has some play.

Anyway, what are my alternatives for the oil pump?

This is a question i also have, need a GOOD alternative to the stock pump.
My rebuild is on hold this is one issue still not resolved.

Good luck with your project, I'd take the case in and get the bores and registers checked before going much further.
