hi all,

i've been strongly advised that my oil cooler problems is due to the thermometer mechanism not opening up and letting oil flow through to the core?

this makes perfect sense as the relocation kit and filter is hot and the braided hoses to the core and the core itself is dead cold even after several track laps.

im just wondering if anyone has encountered/heard of such a problem? was the fix to remove the thermometer/mechanism altogether? or is there another fix?

also, what are the pros and cons of running no thermometer? i understand the fact oil needs to be at a certain temperature to effectively work?

I think its a good idea to run a thermostat in ur oil cooler system cause if u dont it circulates the oil through the cooler as soon as u start the car and it takes ages to heat up, so it stays to thick and doesnt circulate very well, i suppose this can cause engine damage over time. I would just replace the sandwich plate that bolts to the block. I think thats were it is.

Cheers

thermostat, thats the word i was looking for :rant:

yeah i want to keep the thermostat too. i want it to work as it was supposed to! ie. open up at a certain temperature. having said that, i know alot of oil cooler systems which work without thermostat's!?

the thermostat is on the relocation kit for the oil filter i believe? its a trust grex kit....

with the temps we get in Oz, I don't think we really need the thermostat .. believe the original intention was to prevent oil going into the oil cooler during cold winters ? anyway, i didn't bother getting a thermostat equipped one in my car, oil warms up within 5-10 mins depending on outside temps. just drive it sensibly, thats what I do. Did you have anyone else look at your problem franky?

yeah i'm very close to taking it to ben and just telling him to rip out the thermostat. i've also been told that by pulling it out simply giving it a "service" may get it to work again? i can see a replacement thermometer being a pain in the ass to acquire tho! :

yeah my local mechanic and proconcept have had a good look at it. both have been too lazy to open up the relocation kit and give it a proper diagnosis. infact, the only place to suggest doing that has been c&v...the others have just kept telling me what i tell them ... bast&^#! :)

The oil thermostat is there for a reason. Unless you intend to let your car warm up an extra 20 mins before driving anywhere.

But in saying that, you drive like a sook unless you're at wakefield so rip the friggin thing out!!! :(

:D

nismo32, i dont think its the healthiest thing to be running cold engine oil but i do know several people who do it. but i guess they'll never know the true extent of the damage because they wont keep the car long enough to know :(

i want to keep the thermostat.

This is my impression.

Like Frank I use a Serck/Earls kilt. It's way overkill esp. in winter, although we'll see this weekend :(

I do notice that the oil filter is very cool in normal driving?

It's my impression that the motor sends the dirty oil to the filter thence to the cooler and back to the motor?

This is the normal flow as the oil MUST pass the filter therefore must flow to the cooler?

i notice the oil filter very hot whilst driving which is reassuring knowing that the engine oil is getting filtered...

do you ever see your oil cooler core hot?

the 2 braided lines running between my engine block and relocation kit are hot. the 2 braided lines running between my relocation kit and core are dead cold (and so to my core).

my understanding is, and this is coming from my experience with my kit, the dirty oil from the engine block is getting to the relocation kit and the filter, being filtered, and then returning back to the block.

because the thermostat in the relocation kit is not working, the oil is bypassing the oil cooler core. hence the forward and return lines of the oil cooler core (and obviously the core itself) are dead cold...

As far as I know, there's no thermostat in my Earls kit but you're free to ask the workshop who installed mine.

My 19 row cooler is not installed in the normal place (no room!) but it only gets lukewarm but I expected this - I asked the distributor for Serck/Marston if this is normal and they said it was.

The oil filter gets hot but I guess no more than say 50c because it's never uncomfortably hot.

Otherwise the car runs as if the core was not there - warms up as quick as a stock car.

      Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.

      Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.

      OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup

      Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
