[Healeys] Question

[Bob Spidell]

Got curious about something. With all the talk/marketing about cleaners in gas (Techron, 'Top Tier,' etc.), I would be interested to hear from Healey owners who have refreshed an engine in the last 10-20 years or so. I'm not talking about a rebuild of an original engine or barn find but, say, engine was rebuilt 10-20 years ago, run for 30-50K miles or so, then rebuilt again recently (probably gonna be a small sample). In general, how much/what type of crud are we seeing, particularly on intake valves. Would also like to know if there's been any issues with pan sludge, gunk in the ring grooves, etc. Would be helpful to know which brand of gas you mostly use. 

I know a lot of the gunk can be attributed to PCV valves venting back into the manifold, and (most) Healeys don't have them, but I suspect you can still get some varnish on the backside of the intake valves.
