i need 2 know witch oil pipe is in and out on the block as im putting a front oil cooler on my v6 and using the original holes in the block any help will be much apreciated cheers

What has made you decide to do this out of curiousity?

Personally, unless you plan to use your car all day long on a race track I'm not sure there is any point. If your oil cooler has failed, replace it with the revised stainless version, which should outlast the car.

I couldnt tell you which is the inlet, or the outlet I'm afraid; sorry.

moving the oil cooler is one of the better ideas and i dont know why vaux didnt do it from the start as it helps so much with cooling on the v6 iirc the inlet is on the passenger side of the engine as the oil pick up is on that side of the engine when you remove ure plenums it will be apparent which is which as iirc there is a arrow on the cooler to show the flow for correct instalation

GM do it on there engines to aid with emissions. In all honesty, it really makes very little difference during road use to be of any issue whatsoever. If it wasn't for the oil coolers failing, nobody would bother moving them in my opinion.

The end result of this setup is an engine that warms up faster, therefore using less fuel (and pollution!). I'd be concerned about over-cooling the engine oil if you used a front mounted cooler setup, so make sure you use a thermostatic coupling to ensure the oil is only cooled when it actually needs to be.

I'd leave the oil cooler in the 'vee' alone, and use a thermostatic sandwich plate to fit on the oil filter threads, and then plumb the oil cooler in from that. You benefit from this in two ways; first, the original oil cooler can still do its job of aiding the warming up of the engine, and secondly, once the oil gets too hot, the thermostat will open up, and then circulate the hot oil through the new cooler circuit before going back into the engine.

I don't think oil temperature is your problem on V6 track car. Its the coolant temperature. I haven't tracked a V6 Vectra though, so I can't really comment on coolant temperature at all, but plenty of people have if you have a good look online.

im putting a front oil cooler on my track car because even when i had my road car at 200bhp and the cool thermastat it did run very hot when i gave it some hard thrashing and in my mind the water is heating the oil up for no reason so if i can keep the water temp and the oil at a good temp the engine wont get as hot ,and if its a realy hot day these v6 engines need as mch cooling as it can get as they were known to damage the rear head .also my original oil feed pipes had cracked and burst when the oil cooler whent bang in the engine so i bought a automatic transmission oil cooler witch is perfect for the job and it was only £45 with piping, i know some drag racing boys and they got one ov these on their drag car and it works great their oil stays at a steady temp and i like trying new things

[matt-m]

they put the cooler in the v for the american market hence the egr and stupid air pump when you start the car they are all coming off this one and yes i did leave my blanking plate on the red vec opppsssss and i know this has been done on road going vecs too i say do it bud

[3.0 phil]

well the cooler is allready mounted to the rad and pipes ready for fitting i just wont the oil to go in the top and out the bottom less pressure on the oil pump that way but now im thinking bout a light weight flywheel but keep hearing bad rumers bout them

[Tom]

from what I have read over the years, a lightweight fly is the best engine mod you can do to a v6

[3.0 phil]

i spoke to some ppl who had it fitted and they sufferd from stalling and juddering and ov cause the price its not cheap as you will know

[matt-m]

fly wheel is good but you need a 6speed box to make the most of the flywheel
