Heavy braking and my engine sucks air???
Anyone else see this? Repeatably? Oil is at full mark on dip stick (if not a little higher). This is one of the next items on my list of 'to dos' this year. Want the car to be sound for some track use next year. Running Amsoil 0w-30 signature series oil and my engine details are in link below. Thoughts on causes, possible fixes?

I don't think a quart over would be enough to cause problems. When the engine is running, most of it is in circulation, which is why it is so easy to suck air in some engines. An extra quart would be fine I would think.

I suspect that the cooler itself wouldn't drain - but the lines might? The fittings and line are -8AN, ID 12.7mm and about 0.85m long in all, I make that about 340cc? I'll go 0.5L over the full mark on the dip stick and see what happens.

I keep my oil level just over the top of the "F" on the dipstick, run r-comps with lots of sustained corners and never see oil starvation. If I did, accusump is the way. Its probably not a bad idea right now, but I know several peeps who've been tracking miatas hard, for a long time, that don't have this issue.

If it's the stock gauge dropping to 0, it's worth checking the connection on the sender. If it's actually dropping to 0, an Accusump is the cheap/effective solution.
