Ive been thinking and your right, any restriction will increase pressure. Additional volume of oil needing to be moved and pump cant handle the demand maybe, oil cooler not that restrictive so not helping things.
Do wonder if pressure drop like this without logging has caused a few bottom ends...
Done a bit of digging and it does seem to be an issue with many cars with aftermarket oil coolers fitted. I guess a lot of people fit them and do not even check pressure assuming all is good.
Its got to be down to the length of the lines or the 90deg fittings. On other setups ive fitted the oil...
Looking at the datalogs for before and after its down by 0.2bar after fitting oil cooler on initial startup.
Im swinging towards lines restrictive/length of lines at the moment causing the pressure drop.
Im going to log oil temps to see if it needs a cooler for street use, as when driving last...
I did indeed, i primed up the oil system before starting which fills the cooler as it bypasses the stat slightly. Took approx 1ltr more oil than usual to get to the max, and checked again after running up.
Ive fitted a few mocal kits to other/shitter engines and not had this issue before so bit...
Evening all.
Installed a mocal oil cooler kit to a megane r26 F4R today which caused oil pressure drop.
Pre oil cooler fitting with oil temp around 80deg, it was doing around 1.5bar on idle, 3.5k rpm 4bar, poss slightly more with more rpm, engine sounds fine so assume its all good where it...
Pcv actually looks very similar to the clio diesel one. They block up easily in the dervs so defo worth cleaning. Carefully pop it apart with a small screwdriver.
They will most likely have virgined the ecu or fitted an emulator inside. You could try and connect the can lines to an obd port and see if a scanner will delete any codes stored, if thats the case the ecu is unlocked, if it wont let you delete codes its locked.
Id definitely get it gone for...
What are you crimping? For uninsulated amp tyco, delphi etc these are the dogs bollox.

Yep you need the dustcover as its got the bumpstop in it, which is secondary damping on stock shocks/lowered springs, its not included with the shock. Febi do aftermarket replacements which are ok and cheap, i wouldnt refit that one its knackered.
Alternator saga is over (for now)
Went to local french breakers and they had about 30 110amp dci alternators on the shelf, mine had 125amp on but sick of pissing on took a punt as all the meganes run 110amp so picked the cleanest with correct pulley which was reman, daft £20.
Fitted, had to...
Exciter wiring is right by the looks of it as measures 12v with ignition on, just no batt light so assume regulator issues. I snipped the plug off the old Kangoo loom and can see evidence of the exciter wiring having been probed before as damaged. Got to be a duff regulator, if you get chance to...
