Way to go Peter - enjoy your hols!

I'm up for a run - good fun!

Wow! Car looks amazing Howard. Looking forward to seeing the car in the metal soon.

What do you mean by stock?

The original '89 spec spoiler. The Z32 designers got that right from the outset.

Save yourself "buyer's remorse" and stick with the best available.

I would get the car in the air first and establish were the leak is coming from. The clutch slave cylinder is straightforward to replace. I used an OEM part when I replaced mine, but there may well be pattern parts available that are of good quality. Unless there is a leak from the master cylinder I would leave it alone. With the gearbox in, it is a very fiddly job to do in an incredibly tight space. It is also a very expensive part which I had to source from Japan (assuming your master cylinder is the same part# as mine - UK spec type) and you want to reuse the existing hardline.

Simon had a friend of his clean the photo up. In fact I think it was Simon who took the photo on his phone, not bad eh?

Rather nice of the ZClub to feature the cars, chuffed to bits. If anyone is intererested this is the hi-res version. https://drive.google.com/open?id=1fb8GH07qwkPU5Xquoivt4I-hsX-6z6K9

Well no corrosion problems recorded for the last two MOTs. Great barn find.

If the cylinder's seal has an intermittent failure, for example the tip of the seal in the cylinder is worn/damaged or folded back on itself then it is entirely possible for the system to be holding pressure and then start to fail again leaking fluid past the seal. I've personally experienced this problem with a seal. Eventually the seal will completely fail. If this is the case in Chris's car the system can be sealed on occasion and the air expansion problem can manifest itself. The best thing to do is to replace the cylinder, bleed the system and see if the clutch still slips.

Best wishes on your Birthday Craig!

Dot 3,4 and 5.1 (glycol ether based) will damage painted surfaces if left on for very long. Think paint stripper!

What an Aladdin's cave of automotive loveliness!

Yes it could if air got into the system - which is very likely as your reservoir was empty. Any air in the clutch lines will expand greatly compared to the hydraulic fluid. As the air heats up, the clutch engagement point can move closer to the start point of pedal travel. Even with your foot off the pedal the expanded air keeps constant pressure on the clutch slave cylinder, resulting in slippage.

This should help you. The first link is in Japanese, the second is the Google translated version. The JDM folding mirror wiring diagram and mirror switch pinouts are shown (scroll down). http://www.zcar-owners.net/cgi-bin/diy_bbs/cbbs.cgi?mode=al2&namber=11&rev=&no=0 https://translate.google.com/translate?sl=ja&tl=en&u=http%3A%2F%2Fwww.zcar-owners.net%2Fcgi-bin%2Fdiy_bbs%2Fcbbs.cgi%3Fmode%3Dal2%26namber%3D11%26rev%3D%26no%3D0 BTW, what did you install as a replacement for the stock radio? Most aftermarket headunits have a remote antenna signal to power the antenna up and down.

Have you got the ConZult user manual? See page 39 for O2 sensors. ConZult user manual.pdf I've found that O2 sensor readings can stick (not fluctuate), so it is worth running the engine for a while (~2k revs) to see if it will behave normally before deciding the sensor is faulty.

That's the one.

What's the level on the clutch master cylinder reservoir? The clear fluid is probably hydraulic clutch fluid. The clutch master cylinder is directly above the o/s exhaust elbow. See if there is evidence of fluid leaking from it or the pipework/union.

The Selin is a supprisingly effective modification. What make are the BOVs?

Booked.

You need the car's registration to get that report though? A '98 engine would be JDM. Was it bought "engine only"?

Two MAFs can be used with a Selin translator. Is that what you are using? https://www.specialtyz.com/selin-design-maf-translator-elbow-kit.html.html Using BOV's with MAFs is not a good idea. This link explains why: http://www.twinturbo.net/nissan/300zx/forums/general/view/2421113/I-do-not-recommend-blow-off-valves-on-the-Z.html

Nice job. I see you have BOV's fitted, are you using MAF or MAP for air measurement?
