mi 16 oil surge
Does anyone on here know much about the mi16 engine,I've just built my engine and I'm considering fitting an accusump to overcome the oil
surge issues,Also can I fit a s16 tin sump and remove the 15mm spacer at the bottom of the block ?

If you are going to be putting the car on a track, or even for hard road use with sticky tyres I'd strongly recommend an Accusump as a minimum.

The best method would be a dry sump, depends how much your engine is worth. Failing that, an XU 10 16v would be a good cure.
as for sticking with the engine you've got, you'll be looking at a lowered oil pickup, more oil in the sump, so keeping the spacer plate,
baffles,that kind of thing.
Not sure if you know or not, so i'll go ahead and say it. It's caused by stavation due to the head design not allowing the oil to return
to the sump fast enough. Thus any method of remedy would need to keep oil at the pick-up.
A good bet is a good quailty pressure gauge and sender, with a big warning light set to much higher than the OE light, something like 4psi might be
good, but don't qute me on that.

Cheers guys,
Unfortunately I found out the hard way about track use,The car had the gti 6 sump(which is deeper) fitted to the orginal 15mm spacer plate but the oil
pick up had not been altered,I'm thinking of removing the 15mm spacer and bolting the gti 6 sump right up to the block as it works out as the
same depth as the mi sump with spacer.
How good are accusumps ?
I know nothing about them at all.

Sadly this didn't help my friends 205 rally car, after moving to slicks he went through a string of Mi16 engines with various baffled sumps
(including the Peugeot Talbot Sport item) until he invested in a dry sump. In all cases the oil light only came on after the damage was done.
Doesn't make sense to me to be honest, but he's not the kind of bloke to ignore a big amber light on the dash as he was sick of sourcing
and fitting engines.
Craig the Accusumps do work well in general, but obviously have a limited capacity. If the oil pickup is starved of oil for long enough the oil in
the Accusump will run out with predictable consequences.

That's why an after market one is needed at a higher pressure. It's well known that OE lights are utter useless and, as you stated, the
damage is already done.

yep,Im gonna install a 25psi low oil pressure switch with large red warning light.
I've welded a 15mm extension onto the oil pick up this evening to overcome the intiall problem of oil pick up not being extended.
I've been looking at getting an accusump from the states,They seem to be a little cheaper even with postage.
Anyone have any idea on what a dry sump set up would likely cost ? Likely be more than I intend spending !!

By the time you have the sump, pump, tank and hoses you will be looking at close to £1k if you buy new.
