Oil System

[adrianrdaw]

I'm fitting a Kleenoil bypass type oil filter, and was wondering if anyone can offer some info.
On the 1KZ-TE engine, in front of the oil filter, is a stub with a blanking rubber cap over its top, secured with a spring clip. When pulled off a trickle of oil emerges. The engine manual makes no reference to this part of the oil circuit.
Logic says that this should be a low pressure feed, 'cos I wouldn't want 80psi held by only a rubber extrusion. If so, does it come from the pressure relief valve? (which would be perfect for my oil return).I can't tell from the casting shape.
I haven't had the courage to run the engine with this cap removed, and will exhaust the ask others route before trying (I will put a piece of pipe with a restrictor on first!).

Any advice gratefully received

I am not sure as I haven't ever seen one but it might be an access hole for the pressure releif valve.

You might want to have a look here as the 1KZTE engine manual is on line there.

Edit.

Sorry didn't read the bit that you had already looked in the engine manual so I'll shut up at this point.

Anyone else?

Cheers
