Oil filter mounting thing/oil monitoring

[Syncro G]

Got a JX, on the top of the oil filter houseing it has a takeoff for the turbo oil and 1x smaller M10 thread for the DOP high oil presure switch.

Is it possable to get one off a car with 2x M10 holes, plus the turbo one? Guess it would have to be from some form of TD/TDI, but which, if its possable.

Reasion...I want to measure oil temp at the filter head, along with fully functioning DOP and oil presure guage and want to minimise the need for untidy T peices. Is there a notable difference between oil presure readings on the filter Vs cylinder head? If so which position is best for guage, and would moving the high switch to the head a bad idea (bearing in mind you can't Tee a temp sender, which I want on the head and at the moment I only have 1x M10 hole, so if I can't get another both DOP switches would need to move to the head).

There are sandwich plates on Ebay that allow you to fit a number of gauges etc.

This is one. 400021146085. 22 quid. VW used a shortened version of the 068 filter on some Polos so you could use the shorter filter.

Just incase you think they look similar, 1.9 housing will not fit 1.6's

Cheers Andy, so that stops that idea then. Saves a trip to the scrappys.

Don't think a takeoff plate will suit as if one day I fit an external oil cooler there won't be enough space for all that lot.

I think if I get one of them combined oil presure sender/switch and put it on a Tee on the head with the DOP high switch, and then a temp sender in the filter houseing?

Hi,

I have a JX and wanted to do the same thing. As I was fitting an external oil cooler at the same time, I fitted a sandwich plate from http://www.busschmiede.de/" onclick="window.open(this.href);return false; as he sells one that is tapped for a M10x1 sender. Job done!

Cheers.

I suppose you could drill and tap your existing one...

Has that got a thermostat in it aswell? If I fit an oil cooler I'd difinately want it thermostatic. The bisare thing is at the moment I can't prove it needs an external cooler as it seems to run really cool. I tend to cruse at 60 on the motorway but even spanking it up hills at 1bar boost doesn't seem to get the sump temp over about 90°C. Wondering if the filter temp will be much different.

Tapping the filter is an option. If there was a nice flat blank boss on the top I'll do it but I don't think there is, Would it seal right without being on a flat surface? Doesn't sound ideal to me as the houseing is probubly not very thick there. Enough to machine and tap?

Don't know why the oil temp seems unusally low, it usally sits around 80°C. I've checked the guage and thats accurate within 5°C up to 100°C. Termostat opens/closes as it should. Boost is a little high at 1bar, which explains why the BOV kept opening, I've wound that shut a bit more so it rarely does it now - probubly a good safety limit. Don't know what the fueling is, don't intent to mess with it but I think I saw some yellow paint on it so probubly not messed with, it does smoke too bad when you're going for it. I'm asuming that sort of setting isn't going to be doing anything bad to the EGT? Turbo does look a bit oilly, mainly compressor side but I don't want to mess with that just yet, oil consumption isn't too bad. If the waistgate system was to fail, how high would the boost go? Presume more than 1bar so it must be set like that and working fine, the little pipe seems good.

Hi,

Yes, the sandwich plate has a 80 degree thermostat as well - this is the reason I ordered it. The body is milled slightly so that the temp sender fits flush and it seals very well. The type of sender used must have a short body, so it was tricky to find the correct one, but he will supply them.

Indeed, you could drill and tap your own, but as I was ordering a kit it was cheap enough to order the thread with it.

Cheers.

Have limited experience but will try one at a time:

The bizarre thing is at the moment I can't prove it needs an external cooler as it seems to run really cool. I tend to cruise at 60 on the motorway but even spanking it up hills at 1bar boost doesn't seem to get the sump temp over about 90°C. Wondering if the filter temp will be much different.

Maybe not bizarre, but strange compared to all my experiences ... on 2 engines, or 3 if we include a rebuild of the first one. Also note others concurr usually woth AAZ oil-temps, though not always. AndySimpson alos put in very extensive oil cooling to keep temps down, but then that was a hot ship!
Is your engine installation JX canted over and turbo in normal JX position? That would affect it (if it isn't)...

Would it seal right without being on a flat surface? Doesn't sound ideal to me as the housing is probably not very thick there. Enough to machine and tap?

You'd have to work the thickness out yourself by eyeballing it, but no, you don't need a flat counterbored surface, as the sender is a tapered thread and doesn't screw right in usually (pretty sure it's not the female that is tapered, but if you go ahead, just drill and tap a thick plate of ally or brass beforehand to check the outcome)

Boost is a little high at 1bar, which explains why the BOV kept opening, I've wound that shut a bit more so it rarely does it now - probably a good safety limit. Don't know what the fuelling is, don't intent to mess with it but I think I saw some yellow paint on it so probubly not messed with, it does smoke too bad when you're going for it. I'm asuming that sort of setting isn't going to be doing anything bad to the EGT?

1 bar should be fine... My wastegate is often bled so it doesn't open, maybe not a briliant idea with a small compressor and turbine (not intended to be free-floating/self-regulating) - and then EGTs will go high... but this is not a boost problem, its a fuelling and exhaust back-pressure issue (Between the port and the turbine, and a consequence of turbine A/R without a wastegate) My BOV is blocked-off, never seen more than about 15 psi with a normal JX turbo! EGT can only be determined with an Exhaust thermocouple setup, educated guesses can be made, but ... there is a fair margin, but it IS very nice to know steady state cruising values at least (and gives solid data upon which to base further mods/adjustments)... fuelling is the main determinant.
Short-term -smoke when accelerating is often the 'smoke screw' setting, or the star wheel setting

If the wastegate system was to fail, how high would the boost go? Presume more than 1bar so it must be set like that and working fine, the little pipe seems good.

Not sure mine would, but I hear of stories of 18~20 psi or more from a similar setup, but cannot get near that, so I always wonder

Hope that helps

Sounds like that sandwich plate with pressure port would be ideal, but mine doesn't have a thermostat (that can fail if oil temps go over 130C), and with a 10W-40 fully synth, really haven't seen overly high pressures even in these freezing conditions... but I don't start up and stand on the accelerator pedal whatever the weather either. Oil soon gets to 80C as it is... and a much cheaper plate!

Hi SG, have a look on Vagcat.com for oil filter brackets [golf 1982to 1992] they look like they will fit,I have my temp sender in the sump [max so far 132deg c !!] the twin pressure sender is on the cylinder head [ 3 bar cold at idle, 1.75 bar very hot 60mph,.9 bar at idle v hot ].
As you can guess i'm on the lookout for a filter bracket with an oil cooler!.

[Laurie]

I don't know if they will fit, but MK 1 Golf GTIs had cooler take offs in the filter head and a few tappings. The teepiece is going to be the cheapest alternative.

Pretty sure they won't fit Laurie...very weird oil cooler tappings unions on them too and teeny hose dia too. The basic Mocal SP1 or OTSP1 (3/4" UNF) sandwich plate is what most people use.

Its the pipes that will be the most expensive part... can get you an oil cooler easy enough, make own brackets or supply some you can weld on to the two vertical bars.

That sounds just the job then! Does he make/mod them himself or are they an off the shelf brand? Thermostats not likeing going over 130°C doesn't bother me, if I fit the right cooler I would hope not to get it that high and would lift off before. I want it to maintain reliabily and durabilty with standard or mildly increased power, if I was going for more radical gains I aprecheate those conditions could be a very different, and thus require a different compromise.

RE oil temp:
As its not been tuned up its possable (evidently I guess) the stock cooling system is enough, maybe the secret is the rad isn't that old and so works better than most 16+ year old vans? Maybe I don't thrash it for long enough to get the temps up? I certainly don't think I'm in Andy Simpson's league of thermal loading, though despite driving up Pindale afew times in many ways I've never managed more than 1 wheel off the ground at any one time . I guess what I can't quite get over though is over the last year or so I've been reading about scarry oil temps on standard JX and even worse on tuned AAZ and its always been in the back of my mind when driving, now I have a guage it says alls fine no matter what I do, just doesn't seem right, though I'll hapilly not bother forking out for an oil cooler for a bit, I would have got some satisfaction out of doing it though. Still, maybe that intereour will get done afterall if I stop thinking about the interesting bits.

I've had a better look at the pump and it definately got all its yellow paint and lock collars still intact, so its unlikely someone fiddled with the boost eather. Backed up by the genral lack of heat. If you say they struggle to go over 1bar without the fueling upping though maybe the waistgate isn't opening right or the pipe is bad? Only resion it bothers me is if theres any way water can get in through there. I tend to avoid wadeing anyway but you never know.

[KJH]

The sandwich adapter looks like any other off the shelf item, with a custom tap. It was not much extra to order it with the tap so I them take the risk!

[dave friday]

Harry,thanks, i'm going to look in local scrap yards for the oil filter flange first.Syncro G i'm amazed that your oil temp is so low!.
