Replacing Oil Pressure Releif Valves after milkshake

[cro-cro]

This morning i decided to take my 85/2 to get some brunch, I hadn't driven it for a while, put some coolant in (somewhere its leaking very slowly) and heard a some-what low oil sound. I thought maybe it needed to warm up, and eventually the sound went away.

After brunch I realized I had some oil in the spare tire area, so I popped the hood, checked the dipstick and SH.. I checked the coolant, which it looked like it was way low, stuck my finger in and a lil milkshake in there too. I hadn't noticed any white smoke out the tailpipe PTL but it looks like I've got a similar situation.

Right now I don't have an actual garage, I'm looking at a house to buy which has 2 garages, but still a little weary about doing this all my self. Right now my car is still in the parking deck, because I didn't want to make anything else worse, and I'm thinking about dragging it home behind my work truck, and then if I end up getting the place, dragging it there to change out the gasket set and also the bearings. Since I got the car in '11, thankfully I haven't had to do any major work to it, but this might be the first. With the whole buying a house thing, I really don't want to pay someone else to fix it, if I can, but at the same time the show I am working on doesn't give me too much time off for life, or working on a '44.

I've read several different forums about this and have noticed that the bearing replacement is pretty much a must. What about a radiator replacement? I know mine has been leaking slowly, and I replaced the flush screw which seemed to be the problem, but is it needed (just another $-400).

From what I have gathered, I need:
Oil Coolers & Seals
1 Oil Filter/Cooler Housing Gasket, 944-107-147-03
1 Oil Cooler to Housing Seal, 944-107-153-02
1 Oil Cooler to Housing Spacer Washer, 944-107-154-00
2 Adjusting Shims for Oil Cooler, 944-107-219-00
2 Oil Cooler O-Rings, 999-707-043-40

Oil Pressure Sleeve Alignment Tool for 944

Oil Pressure Relief Valve O-Ring
1 or 2 of these? I would think it came in the gasket kit, but maybe not..?

For the bearings, is it just the connecting rod bearings that I need to replace, or the crankshaft bearings too? I see in the suggested there is also a rod nut?
Rod Bearing Set
Main Engine Bearing Set, Std1

If i have to...Radiator

I've also seen people say that you might as well do the timing belt, water pump, and HG while your at it. Thats a lot, why not just do a whole rebuild... I'm trying to do one thing at a time. This isn't my daily driver now, but it is in between film jobs, and I know this one is over at the end of July, so I've got a little time.

Any suggestions and advice is greatly appreciated!
