I have isolated the recirc from the back of the engine oil catch tank to the inlet. This means I now need a separate oil catch tank to collect the oil.

I have an Apexi Power I take so have space in the area where the standard airbox is. I've found a load of oil catch tanks on eBay but they are suspiciously cheap.

Does anyone have any recommendations for oil catch tanks?

My recommendation is to avoid an oil catch tank - they are a real PITA as they fill up quickly and are exceptionally messy (they fill with water as well, from condensation in the crankcase)

I tried it and quickly abandoned the idea - it does no harm at all for the engine to ingest a bit of oil vapour

Fair enough, cheers for the input Nigel.

I'm remembering some of the logic for doing this - to stop the oil passing through the intercooler where it can crude up and presumably reduce efficiency.

Do you periodically clean yours out Nigel?

I haven't cleaned mine out for a long time (4+ years), but it wouldn't surprise me if it needs doing - just got to motivate myself to take it all apart....

Ha, I know the feeling! The hardest part of any job is starting it...
