Finally I have some parts returned to allow me to complete the final stages of the recent mini projects i've undertaken.
First up is the upgraded breather system.
After doing the research I've previously posted about, it's funny how many conversations/items i've read recently about this area, if only I had come across this area previously. Anyhoo, I designed the catch tank and breather setup, the catch tank was made about 4 weeks ago but wouldn't fit properly, so it needed modification. It's back now so I was able to crack on with the install.
Here is the new catch tank in it's new home. I decided that as it has 3 breather pipes, it needed more than 1 air filter.
Here are the pipes from the block, note that the old oil filler outlet is now a breather.
Here is the new cam cover with the relocated breather outlet. I can't believe Peugeot placed the original breather directly above the cam. I suppose as the standard RPM limit is 6700 now raised to 8200 needs this area looked at. So I asked QEP when modifying the cam cover for a new oil filler cap, so also fit a baffle for the breather, here it is:
Here's the new camcover and oil filler cap
And with the breather pipe hooked up to the catch tank:
Next up is the fuel rail mods.
Previously I had an adjustable pressure regulator and it was mounted on the bulkhead, in close proximity to the exhaust manifold.
As I'm going 8 injectors, therefore needing changes to the pipework, I decided to make a few changes.
First up was to move from the adjustable FSE regulator to a fixed item. then I wanted it located on the end of the fuel rail, meaning there were no fuel line joins all the way back to the tank (well as far as the fuel filter close to the tank)
It took a lot of though/discussion but QEP came up trumps. I bought a KMS fixed 3 bar regulator and housing. Then they modified the existing fuel rail to change the push on fitting to screw type so the regulator housing could be fitted on the end.
Here's the results:
Spot the hole for the regulator (well a mini one) Matt didn't have any 3 bar ones in stock only 4 bar, so i'll get that soon. You can see how neat the new install is now (ignore the temp old pipework)
A few other nice touches:
I previously had the vacuum hose coming straight out of the top of the inlet manifold and connected directly to the servo running across the cam cover.
I (finally) located a 90 degree elbow fitting with the correct 1/8th NPT male thread and 10mm push on fitting for the hose. Some nice new vacuum hose to boot:
Next up is the advice from Miles. I blocked off one of the water pipes that are no longer needed with the removal of the heater. So I purchased some blanking plugs (i'm yet to add the 2nd clamps):
you can also see the new Sagem coil pack that was standard fit for later 205s/405s running electronic ignition rather than a distributor. the coil fits to the later thermostat housing a treat
Lastly there's the oil pressure monitoring upgrades:
As well as the new mechanical oil pressure gauge line, i've ditched the useless OE low oil pressure switch that comes on at about 8 PSI for my old adjustable item, an adapter plus was needed to convert the thread from m16x1.5 to 1/8 NPT
So now I have the following oil pressure monitoring:
1 - mechanical gauge
2 - ECU controlled oil pressure warning light (configurable via ECU but expected to be set around ~30 PSI. this will be hooked up to a bright light and will mean, take notice there's a real oil surge issue here. Note the ECU will also control that only over certain revs will it come on, so you don’t get a tan just by pulling up at the lights or switching the ignition on
3 - Mechanical oil pressure warning light which is hooked up to a smaller light on the dash, and will be set to 45 PSI irrelevant of revs, so provide a very early warning to oil pressure issues, and a backup for the ECU controlled version. Yes i'm taking oil pressure monitoring very seriously
Lastly here's a complete picture of how it looks, rather good compared to before xmas version:
