Today I checked the liner protrusion. I put an old liner in and clamped it down using my home made liner clamp tools. (Basically aluminum tube and fender washers) then I took my deck block for checking piston protrusion typically and zerod my dial indicator on a flat surface and measured the protrusion of the liner above the block with no o ring gasket.

measured .002 on both new and old liner which is good. May try again with an o ring to see the difference but I’m not sure if it’s worth using one just to see.

I noticed that the fitting/connector coming out of the block for the oil port has a groove for an oring. That fitting is not shown in eper parts breakdown of engine block or the lubrication system so the oil ring isn't shown either. The big 234035067 oring ITEM 3 I found in Italy is the only one shown but it goes in the groove in the 60562302 (5-spd) 60808390 (A/T) engine support.

So I took that O ring off and kinda screwed myself. I don’t think it’s an o ring. At first I thought it was an oring that hardened from heat etc. but when I tried to take it off it cracked. It seems like it’s a plastic ring. Which is bad for two reasons. One plastic doesn’t stretch so no way I could install a new plastic one. And two the part number doesn’t exist. So now the question is why wouldn’t an o ring work? I would presume it should after looking at both ends of where it’s sealing it looks like it separates oil going into the filter from oil coming out of the filter. So no reason it needs to be plastic right? Let me know what you guys think. The other option is take that fitting off one of my spare motors. But I tried a wrench on it and this fitting is F’ing tight. I even found an old thread on gtv6.com for a 24v swap where they had quite the time removing that fitting.

That sealing ring looks like it must be something like teflon and I have used a heat gun to remove and install teflon seals. I wonder if looking up 24v engines for the GTV or 166 would should that fitting and the sealing ring.

I can open my old eper CD anymore on windows 10.

I only have the cardisk manual for 164 but I can look on totally Alfa’s site that has free 916 manuals I’m not sure if they have a parts IPC but they have maintenance manuals I’ll check.

Found one Fiat 14457280 oring in IT O-Ring Earpiece tube petrol injector Fiat Uno Turbo i.e. 1.3, 1.4 [5514.20] | eBay and similar one in KY USA 87035S94 - A New O-Ring For A Farmtrac 35, 50, 55, 60, 80, 435, 535 Tractors | eBay
I have a feeling though the oring is for the threaded end of the 60515427 connection and the sealing ring is part of that part number.
Ordered that one about 2 minutes ago haha. We’ll see how it looks when it comes in. This one was definitely a hard plastic but I think it makes sense they were updated to an o ring. I also ordered the driveshaft bearing on eBay p/n 60801307.

That 14457280 oring is used on inner threaded end of fitting oil filter screws onto outer threaded end so I am pretty sure it won't be correct size for groove on 60515427 fitting you took hard ring off of prove me wrong. It is item 2 in picture and goes on item 7.

oooooh, didn't think that one through hahaha. but if that's the case ill take the fitting off my spare block and use it with that new O ring. I found the p/n and got excited not realizing it was the seal under the fitting. oh well, well see how it goes.

Are the 12v and 24v crankshafts the same? My machine shop called me and wants to know the counterweight’s weight. I have this chart but don’t know if it applies to my 24v engine.
