A fool proof mechanical device, cool.
So in the event that it doesn't direct the flow to the cooler all will be good? Thats whats I was wondering. I know that the poppet or valve is not prone to fail due to its solid design however..
When you start by-passing the engines life blood you must consider failure points. aside from couplings hoses and the lesser consern of thermo fan switch or motor,its the gate way to keeping the temp down..so Is something to consider. for persons looking for answers.

Hose clamps pop due to high oil pressure when revved from cold
Lines get pinched/kinked
Lines wear through causing sump to pump dry
Coolers under mudguards get speared by rocks
Oil pressure drop and engines wrecked due to lines being too long
No oil cooling at slow speeds/traffic with external-only cooler
Engine wrecked due to shrapnel/swarf in brand new oil cooler


The theory is great, but the practise is not always as good. I seen all this happen...:puke

[ keep the cooler as close to the engine as sensible ie in the LH battery tray posi.

Ahh dude i don't know if i read this right but if you were to put the oil cooler in the engine bay that would be a major waste of time cool air comes in gets turned into hot air then gets sucked into the motor as hot air remember cool air in the engine bay hot air out
You only need two tools
Wd40 if it don't move and it should
Duct tape if it move's and it shouldn't

Run braided lines and An fittings, buy a fan forced oil cooler, build a shroud around it with a fresh air feed. Run a pump that will feed the system you are using. Pressure flush cooler before use, or at start up run a filter before and after cooler, then revert back to before only. Theres your problems solved.
Its about the design and thought that goes into it before hand, not having a failure and saying it doesnt work. nn[ Edited on 9-7-2005 by AdrianH ]

of course things like that can go wrong, but if u think about what u are doing & plan it correctly, any modification can last for many years untouched without any failures.

It's like saying, "I better not get out of bed today"
cause,
I could get hit by a bus
A bird could poo on my head
I might eat an infected mars bar..........

Just do it Twoguns, you'll be fine. Just keep the stock doghouse cooler as well.

The LH battery tray posi could be like so; Cooler positioned over vents in that spot with push through fan(same direction as vw engine cooling) or oil cooler on the underside of tray spot through a hole or vents then ducted up to the the rear set of intake vents.on the aussie split Post 65.
You know like a chimeney?. Heat rising.
Theroretically you'd be recycling hot air and minimal amounts of exhaust. though you would have spent a weekend creating ducting from aluminium sheet rivits and sickaflex in order to vent cooling air up and being assisted by a couple of computer fans. I dont think blocking off one bank or even half of one bank of ducts would starve the engine. My understanding is that the principle for ventilation in the Kombi when moving is the same as the air fuel chamber above the throttle body on a turbo set up,with a reserve of air in the engine cavity in this case the fan drawing on demand. The idea of the duct is to remove as much the induction/ingress of hot air into the engine cavity and in turn back over the hot block. If the cooler is on the underside although more in harms way,Its intake hoses are better in line with oil pump and galleries. less turns etc. No way will I put it under the vehicle. Especially on a lowered kombi like 2guns'es'es. Its just another thing to worry about. Its ballsy enough being a human bumper bar up front.

If you have seen all this happen then you have seen some of the worst preparation, installation and maintenance possible.
There is an old saying dude, "you cant educate f***wits" and obviously these are the kinds that have suffered engine failures as a direct result of a dodgey oil cooler installation.

Obviously, these examples are the result of shoddy installation, poor plannning and straight out stupidity and lack of observation of a red warning light.
I'd go as far as say they may have deserved their failures.

Fancy locating a relatively fragile oil cooler under a mudguard....subject to grit, stones and sticks being thrown around under there......Would you place your radiator there in a watercooled car? yeah sure!

Pinched, kinked, too long and holes worn in oil lines......there were serious, serious issues with the original installation in these installations, mostly of the soft penis kind.
If the original installation had been planned and carried out correctly in the first place then there is bugger all possibility of damage to the oil lines or significant oil pressure drop.

Blowing off lines when cold?? How high does the oil pressure goe when cold then?? What, 10, 20 even 25PSI above hot sound feasible?
The lines would have blown off by themselves eventually anyway due to faulty installation or incorrect lines or fittings.

The problem of lack of airflow over an external cooler at slow speeds is a complete no-brainer and the matter has been dealt with many many times on the forum.

Im not even going to comment on crap in a new cooler other than he got what he deserved for cutting corners.

Cmon dude, there are a legion of happy and reliable external oil cooler jockeys running around for year after year and their engine are alive and well and their oil is healthy and happy. You have been subjected to the very worst of scenarios as a result of lack of knowledge, ability, planning or a combination of by the original installers.
If they were amatures, then they should have sought professional advice before embarking on such a...... technically challenging task, if they were "experts" then they are idiots, simple!

The position im suggesting is beyond the guard.The Lh battery position. And by the way Expert, or near to. Do you have any useful suggestions in regards to the location of external oil coolers. Where do you you run yours?, bearing in mind the back Half of your car is Missing in Your Avatar. Plenty of wind there.

twoguns to answer your original question,i have currently 6 splitties onwners with a fool proof reliable external oil cooling system.engine sizes vary between 1776-1835-2180..all have a various compression ratios..all are dual carbed.Each engine runs a stk oil pump [30mm] with a gene berg pump cover with a relief valve[helps avoid oil fitting blowoffs]all have a remote filter under the lh batteryfloor which is protected from stones and easy to service,all use a inline oil thermostat [i've used for over 20years] mounted near the lh torsion housingwith oil cooler grade hose running to behind the front axle..a mercedes transmissiom cooler which is wide and thin sits on a simple bracket with a good air supply,it is also very well protected in this region from stones and has'nt affected ground clearence..all these kombis run at 80degrees normal city traffic and when given the boot and cruise at 110-120kmph[all irs and lowered] hover around 90-105 degrees...have personally travelled 10s thousands of k's with this set up without a hicup..yes a bus does work a little harder than a bug therefore oil temp is relative..purley a wind resistance issue.all still retain the std dog house coolers and a type 4 cooler upgrade is a bigger plus ...all buses use std pulley configeration..hope this info leads you into the right decision for your requirements..remember this is a tried /driven and proven result on splitty buses. cheers dsk steve

I got a pressure gauge on a T fitting where the pressure switch is on a stock type4 and at start up it reads 70-80psi and at idle when at running temp about 20-25psi and upto 50-60psi at higher rpm at running temp ---- 20-50w oilnn[ Edited on 10-7-2005 by 76camper ]

I have one of steves setups, have travelled 10,000ks in the last 10 weeks, twice to sydney and not missed a beat, cant get the temp hot at all...looking forward to summer for her real test...and the cooler cost $20 from pick and payless...

I agree that a thermostat is a really good idea I got sick of the creeping up creeping up oil temp on trips & have now (about two years) have a remote oil filter & a good cooler mounted flat between two of the chassis rails about at the rear of the sliding dor & can happily drive any speed I want (can get to) even on hot days & valve clearances also do not need anything like the adjustments they used too
the oil does take a lot longer to warm up though, so I use 5W-40 HPR5 & will be getting a thermostat
Please, I need drivers side window regulator (winder mechanism) for my '54

911 Porkers run the cooler under the guard

My 1200 pulls 70= psi at start up and 30 at hot idle

I run a in/out pump + spin on filter + oil cooler (from a datto skyline)

I have hose clamp fitting on at the moment but i will switch to Earls fitting as soon as I pull my finger out and get around to it

Twoguns I use an 8 pass cooler mounted in the nose of my buggy along with a high flow oil pump and filtre. With this setup I can rev the fork outa my 1776 all day long in first gear in the sand and the oil temp wont pass 90 deg. With the long hoses to the front off the buggy along with the cooler/filtre I fit another 1.5 litres off oil in my system and running 50-60 psi off oil pressure have never had a blown line or even a drop of oil. Fit the cooler mate, but two bits of advice- keep the oil lines and cooler inline with the engine as much as possible or you will have to root around alot when its time to do an oil change, and get in the habbit of starting your vw a good 5-10 minutes before setting off cause they take a LOT longer to warm up.
