Roger Chatfield 0 Posted August 19, 2014 Thats what I'm going to do Kev, the VW owners manual says don't even begin to worry until 140 and like you say modern oils are far better at handling heat that the stuff that was available 20 years ago. Also, I've got a new rad and have flushed all the pipes and block through so that should improve my cooling. Rog. Quote Share this post Link to post Share on other sites
Jim 2 Posted August 19, 2014 So what are your average motorway / cruising speed oil temps, Rog? Quote Share this post Link to post Share on other sites

Also, I've got a new rad and have flushed all the pipes and block through so that should improve my cooling. Rog. VW removed oil temp from the MFA on R32s, and also engineered the water gauge to always sit at 90 to stop people worrying :) We did find the oil temp in Pat McCrotch's old MK5 R32 though, in a hidden menu. That was reading in the mid 90s. R32s take the reading from the sump, so I think reading the temp from the oil filter housing is skewing the readings, especially when you consider the R32 makes more power and therefore generates more heat. Yep, changing the radiator and (mechanical) water pump, thermostat etc on mine made a big difference to running temps. Mid 80s on the water and mid to high 90s for the oil.

borachris 0 Posted August 19, 2014 Kev do you think if I drilled and tapped a sump bolt to fit the standard temp sensor it would give a more accurate reading than fitting it in a t piece with the pressure senders? Quote Share this post Link to post Share on other sites
Dox 23 Posted August 19, 2014 You can buy sump plugs already tapped 10mm x 1mm off the shelf http://www.ebay.co.uk/sch/m.html?_odkw=sump+plug+10+x+11&item=371117125893&pt=UK_CarsParts_Vehicles_CarParts_SM&_osacat=0&_from=R40&hash=item56684df105&_ssn=jjcraceandrally&_from=R40&_trksid=p2046732.m570.l1313.TR0.TRC0.H0.Xsump+plug+10+x+1&_nkw=sump+plug+10+x+1&_sacat=0 I had on my MK2 with VDO gauge set up Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted August 19, 2014 Yeah that could work. Even easier if you've got an R32 sump, just drill and tap it as it should be thick enough :) Make sure it's round the back out of the airflow though. Or maybe there is something on the market to replace the dipstick that acts as both a level and temp sensor? Quote Share this post Link to post Share on other sites

Kevin Bacon 5 Posted August 19, 2014 It must be doable fairly easily I would have thought, but it might mean a standalone display, which purists won't like ;) Incidentally, BMW removed the dipstick on some American market models, but people complained so much they had to reinstate them!! I guess some people struggle to move on with the times! Quote Share this post Link to post Share on other sites
borachris 0 Posted August 19, 2014 Kinda like making a dipstick out of an EGT probe! Cheers Dox i'll have a look at them, I don't really want to take the sump off if i can avoid it Kev Quote Share this post Link to post Share on other sites
Wullie 1 Posted August 19, 2014 Or maybe there is something on the market to replace the dipstick that acts as both a level and temp sensor? I had a Talbot Horizon which had an oil level indicator light on the dash. The dipstick had an element built into it which reacted when the oil level dropped below it allowing it to heat up. Doesn't seem a great leap from there to what you suggest Kev. Quote Share this post Link to post Share on other sites

science 0 Posted August 19, 2014 Or maybe there is something on the market to replace the dipstick that acts as both a level and temp sensor? I've got one on my MK1, it's made by VDO and it's height adjustable for different cars. I'm sure it's compatible with the standard MFA gauge but I'm using an analog VDO gauge. Reads between 5 and 10 degrees lower than the MFA. Quote Share this post Link to post Share on other sites
Wullie 1 Posted August 19, 2014 Now there's a car! It took a bit of thought before I typed that. It was not a bad car though, if you could ignore the clattery engine and that it was soluble in water. Not a good point given the average Scottish weather. Quote Share this post Link to post Share on other sites
