Lack of maintenance or heavy track use will cause it, never heard of the oil priming thing being an issue I think that's made up internet diagnosis talk. From memory the S55 sump has baffles and bolts on and mitigates the starvation problems at the track. Accusumps are cheap too

My system has likely been dry for 10 years, so I'd worry about the o-rings being dried out. My understanding is that r134a molecules are smaller than r12 molecules, so they'll leak out of the old lines no matter what. I suppose I could start by pulling vacuum on the system to see if it holds, and then go from there.Just get some r134 shrader valves and fill it lol
That's a cheap "conversion"
Been running mine like that for 10 years almost and its still ice cold.
Really the only thing worth changing is the condenser to a parallel flow, but if its not getting above 90 degrees you wont really notice.
Then again, we do get some really hot days above 100F. The other day it was 85F, but I saw 100F when sitting still in traffic. I'll probably still go for the whole conversion just to get nice cold AC that I can trust. I want to be able to drive this car regularly.
I did a Blackstone analysis a while ago and it came back fine. There must be million cars out there with an n55, and you don't see/hear them constantly spinning a bearing. Its probably just hyped up from a few examples of cars that were tracked or poorly maintained.
From what I've heard, the n55 components can't be machined to be rebuilt once a bearing spins. So you'd need a new crank and rods. That sounds a little fishy to me, but that fear is the biggest driver of wanting to avoid bearing problems.sigpic

m20s are pretty solid.
Basically look at the timing belt history. Open the oil cap and coolant rez and see what it looks like in there.
See how she runs and what temp it runs at.

I’m guessing it is for sure that, series 1 aka early.
Other places calling things other things always interests me.

I hear tops are expensive, and in AUS your UV problem is probably as bad as or worse than it is here, so the seals, rear window, and top, may be on borrowed time if the car wasn't garaged for its entire life.Comment

That's no bueno, sorry dude, since I only know internet details about ya, is this from fab/race shop workplace? Or is it a soul sucking workplace not related to that?
I hope whatever happened this can be turned from a negative into a positive for you, like what Sir Reverend Biggie Smalls said.Comment
