Does it have another name? Part number? Ease of replacement?

Thanks

It’s the plastic thingamajig on top of the engine with several small hoses prone to cracking after 7 or so years due to heat fatigue. Replace this and water pump at timing belt change (and oil pump housing if <MY09)

TRS here in Adelaide have billet alloy units available. I have no connection to trs, im only a customer. Ive seen them there

Think the consensus was that it’s cheap enough as a genuine part to replace each 7 years or so.

Have seen them there. Tempted but a tad expensive.

Am going to replace it when I do the flush.

Seen it referred to by a number of names but never a “crossover pipe”. Not really a pipe at all.

All Fourx4 do a kit including an extra o-ring for the oil cooler connection:

They’ve had a few fail too!

That family doing the big lap had a stock one go (very old) and fitted the billet unit - and it failed very quickly.

The genuine part is $75.00 and goes 5+ years
