thanks dan

the only problem i see with having the oil filter upside down is that when you turn your car off the oil will rush out of it. this means that when you turn your car back on, you'll be running without oil pressure for a while before the oil filter fills up (around 600ml worth).

if you insisted on having it upside down i'd suggest having a loop in both the feed and return hoses to stop oil from rushing away from the filter when you turn the car off.

for eg, the feed line to the oil filter would look like this:

the distance at a) should be as short as possible so oil rushes up to the oil filter and starts getting distributed quickly.

Going out on a limb here, but don't filters come with drain back valves?

not that i know of

I believe many filters these days have them, Mobile 1 for instance.

Dan, you could alternatively fit a one way valve to the line before the filter relocator

heaps of the japanese relocators are vertical mount.

plus the filter is inclined when just on the block anyway...

mines upside down attached to the block .. so id hope so... however I do start my car and the oil gauge doesnt move for about 3 seconds .. this normal?

this is the point im trying to make. most of the filters that suit these oil relocators are off commodores (not jap) and are pretty big. alot of the ones made here, like the justjap ones, use filters off commodores.

its not normal to have no oil pressure for 3 seconds. mine fires up almost instantly.

pretty much any filter i've used had a drain back valve. and min is intalled that way (ie hole points down). it's not fool proof though, some oil still comes out when you take it off.

The filter you are referring to (the Ryco Z145A or equivalent) is off an RB30 motor, so VL Commodores & R31 Skylines. It is larger that the "proper" Nissan item, but if you have had a good look at the Nissan item (I have a spare at home) you end up thinking "Yuck, not going to use that". Or similar sounding words. The larger filter is better in that it can hold more filth before it degrades in performance. Downside is that they are a pain in the arse to fit past the HICAS unit.

Just about every filter you can buy has an anti drain back valve. It is just a bit of rubber that stops the oil draining out fron the filter. In any case filters are basically just paper/cardboard so I can't for the life of me figure out what all the fuss is about.

couldn't you just turn it upside down so the the filter screws up from underneath. i'd say that would cause less mess then removing the filter than having the filter screw up from the top. even if you have to mount it down off a chassis rail so you can get to it easily from under the car while you are taking the sump plug out.

i thought that was his original question, can he mount it upside down as in the filter's thread pointing up, so when you unscrew it, it's full of oil but held in a way so it won't spill out...I've always wondered this - it would save having to hold a rag under the filter when you unscrew it.

That's what I've done with my relocator/oil filter and it's made for some of the easiest/cleanest oil changes I've ever done! Mine's not mounted in the engine bay either, so very easy to have a tray or something underneath it and oil doesn't get on anything else

yes that is my original questionsimple turning it 180deg so its upside down... which i will do so on the weekend when i install. just to add to the convo i was given a honda z160 oil filter however im going to use a ryco z30 which yes is off a commodore however it does look to be the same size as the nissan filter i have on there now

the best solution is to have it so it screws up from the bottom. only problem i could see when doing mine was that the small amount of oilt in the relocator block would rush out when unscrewing the filter. still thats better than having no oil pressure for 3 secconds.

you could fix that by running some 90⁰ fittings from the plate. it will minimise the amount of oil thats left in the hose.

if the filter is mounted strait up like threads are pointing down to keep oil from coming out when removing the filter u can take a screwdriver and puch a hole on top of the filter before u remove it. this will allow pressure to leave the filter allow oil to flow out and u can remove the filter with no mess! i did that on my old setup on my sr20, worked perfect!

ruff but afective. i think i was just being too picky as it is by far the best way and depending on here the relocator was mounted it would be easy cleaned anyway.
