Got my oil cooler fitted yest, was unsure where to mount it etc. But i put it on the inner wing above the gearbox... Lovely job - Until i started the car up, it took several "cranks" to build oil pressure up then once i started it up it chucked oil out of the cooler, between the cooler itself and one of the factory fitted mocal unions, that seem to be tack welded in position.
Now this concerns me somewhat, firstly it can't be a thermostatic cooler although i brought it (2nd hand off here) as one, it does seem to have a stat in the take off plate though.
Secondly it leaks, and i don't wanna start welding the cooler up to repair it for it to leak again later...
Thirdly all the time i spent fitting the damn thing was wasted as i've gotta do it all over again!

 

Mine was brand new Roger and it leaked where the pipes were attached to the sandwich plate and where they join the cooler. The threads on it just dont seem very convincing at all.

When I fitted it I span the engine over with no plugs to fill it with oil, then left it a bit to settle in the sump and topped it up as obviously the cooler will need a little oil adding to the total.
Still leaked even after tightening so I took it off and haven't touched it since!

 

No thats what im gonna do i think, i covered all the threads in PTFE aswell, but its leaking from where the union joins the actual cooler...
I'll get an oil temp gauge soon and see if i actually need a cooler lol!

 

Is this in addition to the stock one? My oil temps never rose over about 100c on my CVH just for reference mate.

 

I have taken the stock one off as im told its crap and can end up with water in the oil etc..

 

My stock one fucked up. Blocked oil pressure and cost me my engine

 

Oh! lol
Never heard of that, would have to of rusted through I guess?!
I don't run one at the moment, need some more pipe and havent got round to it yet.
Oil temps hit maybe 105 degree's so I'm in no rush.

 

First thing I did when get my next one was removed that and ditched the water cooling to the turbo and fitted a 82degree stat. Nevers gets hot as only a mild tune (160 bhp ) would invest in a oil to air cooler if I went more revs / boost though. Got a oil to air on my zetec s as used to see oil temps of 120 regularly. Saying that the water fan do t cut in till 110 degrees.

 

It can be, Mocal's are designed so the sandwich plate lets some oil through, but some goes through the cooler too, even with the thermostat 'shut'.

 

Oh ic, maybe i'll repair the cooler then and try re-fitting it, not anytime soon tho lol!
I was thinking of trying to reduce the coolant running temps somewhat, thinking maybe the oil is getting too hot and heating the coolant!

 

Sorry to bring this up lads but I took off my cooler, red seal is broken, I have been filling it full of oil and blowing out with air , convinced there is build up of mayo in it, ok to run with out? What about fitting a mocal

 

i run a little mocal 12 row with the thermo block (stat in it ) never had no issues at all seams to work very well

 

Pic of install man?

 

I had mine mounted in a similar position, worked brilliant;

 

I'm keeping standard air box

 

@ mattcroft..that oil cooler is doing nothing in that position.There is no airflow going thru it what so ever.This topic was done to death about 2 years ago in this forum.Regards,Micky

 

The original CVH one is actually a very good piece of kit. Yes they do like to rust (tho usually at the coolant hose joints). If you've always used a good mix of coolant and the joints are good, theres a high chance the internals are in the same state and your not going to run the risk of rust collapsing inside and mixing the two.

Like Karlos i never hit any temps that were an issue using the OE kit.

 

Ive always assumed the Laminova works in the opposite way ?

Uses the water to warm the oil up on cold start ups and such ? Surely this isnt going to cool the oil at all when the oil is around the same temp as the coolant anyway ?

Ditto the cooler comment it wont be doing a great deal sat in that position you need to get some air flow through the core

 

Works in both ways, as you say, will help bring the oil to temp but then it will also keep it stable (cool was maybe the wrong word).
