Umm. take me a photo of your engine with the PCV /catch/routing easily visible ? It looks like stuff is only coming out of your 'breather filter'. Will do, for this it was stock intake side and the filter exhaust side, with the stock PCV. I was going to route the exhaust side to a catch can with a filter, although there is no filter media/perforated plates inside this one - can I just fill it with wire wool? This is basically it, but the filter not fitted, I'll update when I've got the catch can installed, but essentially stock bar the 1 catch can so far.  2022-09-16_11-24-46 by Scott Reid, on Flickr Looking at your other posts HERE, I'm considering the DaveFab catch can (non-VTA) between the cam cover and intake, although would I keep the PCV in situ or replace with a barb. I'm not entirely sure yet. |

with the oil coming out your breather filter and a stock routing, it looks like your PCV valve might be blocked, or failed under boost.
Suggest you check it flows / clean it out.
there's nothing wrong with running a catch can on both sides. It's what I do.
I run a OWV and the stock PCV valve. OWV is to stop boost from getting to the PCV valve, which if it's stock, was never designed to see boost.
on the 'exhaust side' with my setup (dual catch can) I _NEVER_ see oil in there.

Yeah I'm hearing the same thing from a few places, I've the uprated PCV on it's way. Have you got VTA on your intake side? or is it NON-VTA? I've nowhere I can fit a catch can neatly that side, which is why I'm looking at the DaveFab kit. |

Turbo Car ? I run the main catch on the intake side which is the side that sees 99% of the actual fumes from the head in the stock PCV setup. You've buckets of room to fit a catch can on the intake side. Just dig up the original support for the charcoal canister. Or get one. It's a useless lump of metal otherwise. I roughly cut a bit of 2mm/3mm thick Ali into a 'V' shape such as the charcoal canister support is designed to hold and bolted the catch to that. see: http://instagram.com/p/CdREWoSsHZI on the intake side the routing goes head > pcv > catch > OWV > intake manifold |

Nice one thanks atlex, that should be enough to get me started at least! |

atlex, does your exhaust catch can vent down to ground? I've redone the setup, so not it vents correctly into the catch can, but I still see some fumes out of the filter itself, but substantially reduced (certainly no oil now). I've filled the can with wire wool. Also fitted the 323 PCV, which seems a much better unit than the one I replaced.  IMG_20220925_185613 by Scott Reid, on Flickr  IMG_20220925_185606 by Scott Reid, on Flickr I'll sort a catch can out on the intake side and get the materials needed to soak the rings sorted out, for after tuning. Have also maybe picked up a 3" kraken exhaust system, only thing is it's for a mk2 so will need the hangers modified to suit a mk1, I'm hoping it'll quieten down the car a bit as currently it's still too loud.

Yet again something I've agreed to buy has been sold to someone else, getting a bit frustrated with Facebook market place. Anyway, car made it to work, then up to the tuner in Perth, total of 2.5hrs driving, sat at 65mph which it seemed ok with, no real drama. The 4.1 Torsen will need swapped for a 3.6/3.9 to stop cruising at 4k+. I think I'm going to look into going 3.6 with a 6 speed, get the diff first and sell mine to fund the 6 speed - although they've all gone daft prices recently. In other news, the MeisterR Clubrace have transformed the car, from bouncing over every bump in the HSD's I'm now gliding over them (on full soft). Found myself a couple times, flinching going over bumps on my way to work, that the HSD's couldn't handle, to find the MeisterR aren't even unsettled. Game Changer! Absolute different car now - I would say don't skimp on suspension, go as expensive as you can. Admittedly I think the HSD's were dead when I got them and I've ran them for almost 5 years, but still....learn from me (I'm sure you all already know this)  Anyway, no more updates for a while until the tuner is done. So I'll spend my time looking into diffs, gearboxes, exhausts. |

My Eunos had HSDs on when I bought it, they are just far too hard apart from on track. I've recently picked up some MeisterR ZetaCRDs that I need to get around to fitting, and hopefully the transformation will be of similar impact. My navigator should appreciate it too!

Absolute night and day for me, it was getting to the point I was hating driving it, they just couldn't deal with any imperfections on A/B roads. I think a couple times I actually bounced so high the rears lost traction! |

Am a bit puzzled by your gearing: Mine gives 82 mph on 4000rpm with a std 5 speed & 4.1 CWP. You’re right about the 6 speed boxes though, silly prices & the diffs too.. Club races are good, vast improvement over HSDs which I’ve had on mine too, although I soon got rid.😁 |

Re: diff I think I've now confused myself, I'll do a log to see what RPM it's sat at, I seem to think it's close to 4k, but could be remembering it wrong. A 4.1 would be 3463rpm @70mph A 4.3 would be 3632rpm @70mph www.flyinmiata.com/tech/gearing.php I think I've the needle in the wrong place so it reads slightly high anyway, from swapping in the gauge faces. I'll reset it now that I've got RPM visible on TunerStudio. So either I've a 4.3 (result) or I've noted the wrong rpm (also result). But looking into it a little more, going 6 speed and 3.9 seems to be the sweet spot for my power levels, but it only saves 200rpm from cruising speed, which isn't going to make a huge difference to mpg. Maybe stick it out with the 5spd/4.1 for the foreseeable - if that's what it ends up being. Anyway, the tuner has managed to fix my high idle on cold start up, but it's now become a pig to start, he's wanting to move to a crank angle sensor. So I'm hoping for the best! |

Small update, tuners fitted the 36-1 trigger wheel and mk2 crank sensor, from the videos he's sent it's starting like factory repeatedly, so that's good news! He's still got to fine tune cold start and idle, but so far so good. Couple points he's made: - Running temp for the coolant, gets up to 95 degrees. I've seen it sit at 93, with peak 95 (it did this whilst N/A also). - Voltage drops, from 14 to 12V, he suspects my alternator is on it's way out. Recon unit? - Turbo's too small - no surprise here, we knew that'd be the case. I think we see full boost by 2900rpm and it drops off past 6krpm. Plan is to run as is, go GT2560r eventually. I had hoped the BP4W head might give me some more room, but I don't think that's the case. - Exhaust needs stepped up in size. Currently it's a 2.5" downpipe to 2.25" cat back. Trying to get my hands on a 2.5" cat back......but Facebook marketplace (you'd think he didn't want to sell it). If that falls through I'll go 3" custom cat-back. Then eventually go Kraken mani/3" DP long term. Plan is to map it to 0.8/0.9 bar, I've said I'm not chasing numbers, but I would like to kick it's head in repeatedly without worry. He's also fixed my shocking wiring, which seems to have fixed my bouncy tacho issue (I'm no sparkie). Still gathering parts for when it comes back, but I've got the Spiked Performance bonnet vents to go on. I was looking at a coolant re-route (I know this is divisive on whether it does anything), looking into dual SPAL fan setup (another FB marketplace effort). The wife thinks I should look into brakes also. Tuner describes it as nippy, but then his datum is a k-swapped turbo RX-7, with a Tailgate McNoIndicate DCT, so I'll take nippy Catch can adjustments are working also, I still need to get one setup for the intake side. Apologies for the waffling on a bit. |

So a 3.6/3.9 and a 6Spd would be worth it eventually then, I still need to confirm my diff is what I think it is. Good point about the fans, I'd forgotten in all my rambling, I'll fit up the bonnet vents and see where the coolant temp/intake temp sit afterwards. I don't see many stepping up to aftermarket calipers from a refreshed stock setup, so will see how it goes, in all likelihood it won't see a track anytime soon. Had some more updates from the tuner, everything going ok so far. He's has it at some "interesting" speed checking the tune and sent a video (which I can't share). It's running on some 5W30 fully synth just now, I see a lot of people step up to 10W40, but I do see quite cold temps up here so wondering whether to stick with the 5W30 or go 5W40? (yes I know oil is a can of worms sometimes). It's holding a consistent oil pressure whilst doing a pull anyway. Cannot wait to get it back! |
