[quote][i]Originally posted by Kyle T[/i] Yup it's a pain in the ass. I imagine paying for a gauge installation can get quite expensive, nothing is hard about them but seems to be quite time consuming so I'm happy to slowly work through it myself. I did indeed pick up the sump on Friday so that allowed me to get covered in oil (a few times) over the weekend. The engineering shop had drilled a 1/8npt thread into a blanking bung that the sump came with which made for a nice fit for my oil temperature probe. I wound this in with some teflon tape and made sure the sump was properly cleaned out. I idled the car for a bit while I tinkered about to get some oil temp up, then dropped the old stuff... which wasn't very old at all. [img]https://i.imgur.com/v4aIfqc.jpg?1[/img] Pictures are few and far between now because I ran out of gloves and my hands were a complete mess, but after dropping the oil I had 12 bolts and 3 nuts to undo on the current sump. The 3 nuts were on studs in the block which needed extracting before the new sump could go on. The new sump has a thicker flange so came with longer bolts (15x) for all fixings. Once the studs came off it was the painstaking process to clean the oem gasketmaker from the block. This engine/sump combo didn't come with a real gasket from the factory so you need to sort out your own messy version with a liquid gasket. Cleaning it off took ages, but once done I wiped everything down with a degreaser. Once cleaned I put a bead of loctite stuff round the new sump and then shuffled into position. Putting it into position without the 3 studs to guide it on was a bit of a pain in the ass but I managed to get it on with minimal smearing of the bead and got a couple of bolts in hand tight. I did find that a couple of the bolt holes didn't quite line up - off by maybe 1-2mm but with a bit of adjustment I managed to get all 15 in without drilling or enlarging any holes. The torque spec for these is way under the minimal threshold for my torque wrench so I winged it. Hopefully it's fine [img]https://i.imgur.com/KfR3cs6.jpg?1[/img] Pictures are a bit out of sequence as you can see the installed oil pressure sensor in the background there, but that came next. The factory oil pressure switch is fitted just above the oil filter housing and in all the pictures looks dead easy to access - but as my car has the twin front oil coolers, it's totally blocked off by the pipework so I had no chance of getting a spanner onto it. A trip to Halfords later and I had a tool that I hoped would help. [img]https://i.imgur.com/pwT2WQp.jpg?1[/img] Sure enough the socket went on (just) and with the 3degrees of angle I could get on my ratchet I (very slowly) took it out. My plan was to replace this with a remote t-piece and then refit it along with a new pressure sensor for the gauge. I did this on my Subaru and much prefer this approach to screwing a t-piece directly into the block as it seems to add a lot of weight and leverage to a cheap 1/8bspt fitting. All parts teflon taped in, this adaptor is 1/8bspt male (to go into the block), 1/8bspt female for the original switch and then 1/8npt for the new sensor. [img]https://i.imgur.com/Wk4lbxT.jpg?1[/img] Once fitted, I had a P-clip to mount it somewhere but I can't (yet) find anywhere obvious so it's temporarily cabletied to an oil cooler line. This may end up permanent if I don't find anything better, as long as there's no weight/strain on the fittings during engine vibration I'm not too concerned. [img]https://i.imgur.com/I7xRApr.jpg?1[/img] Both sensors are now easily accessible and easy to check for leaks. Final job for the weekend was a boost pressure sensor. I found a nice threaded hole on the rollover bar support to mount the sensor itself which was within a few inches of the pipework on the cold side of the intercooler. [img]https://i.imgur.com/SDULfMg.jpg?1[/img] I popped the pipe off and cut some spare 63mm silicone joiner up to make some slightly longer joins. This extra length would accommodate a self sealing nipple attachment: [img]https://i.imgur.com/NrlWcRL.jpg?1[/img] Once refitted I could connect up to the boost sensor with some vac hose. The sensor came with a cheap inline filter, I had one of these fail on my Subaru but to be fair I was running almost 4x the boost pressure that I expect this car to be... so hopefully it's fine! [img]https://i.imgur.com/dhSfaVq.jpg?1[/img] I cut up my silicone with a stanley blade that's a little second hand - so I'll whip it all off to tidy it up once I know the setup doesn't leak. If I get any boost leak issues at all like this, I'll just revert to the standard setup and do without a boost gauge - it's not my long term goal anyway once I get a decent gauge fitted. Once installed, I gave the loctite 24hours to cure and then filled the car with oil, including the extra 1litre capacity. I had a particularly frustrating 45mins as I dropped the dipstick into the engine bay and it totally vanished. I couldn't see it from above or below and spent the full 45mins trying to find it. Eventually I decided to take a wheel and arch liner out for a different perspective to find it sat curled up in the sidepod! Unbelievable how a 2foot pole with a bright yellow handle can vanish like that. Oh, and I almost forgot - sometime between all that I also changed the gearbox oil. [img]https://i.imgur.com/jz01nin.jpg?1[/img] I still had half a bottle left from my Elise change so I used that to flush it through a bit, then pumped in 2.5 bottles of the new stuff. This stuff stinks, but I'm slowly growing to like it. As with the supercharger/aux belt - this is a service item that I can't find record for, so at least I can tick it off now. I did a few mins of oil pressure testing last night, unplugged sparkplugs and cranked it a few times to get the pressure light off and checked for leaks. Everything seems dry, so once I get my gauge wiring (hopefully early this week) I can finish off the gauge install and leave the car running for a bit longer to keep an eye on pressures and leaks. My social media feeds are filling up with people getting early trackdays in... so going to have to get stuck in very soon! [/quote]
