No obvious pick up pipe in the block unless it's cast in :-\

with baffle removed see pics in link

the pick up pipe is part cast into the sump,part a removable pipe/strainer as pics in link above
the engine block has an oil pump bolted to the side (crankshaft driven) that sucks oil via the hole which mates with it at sump gasket /sump

Here is the sump full of sludge, tilted to show how much sludge there was.
What chance had this engine to give full power; and what chance had I to foresee it?

I cannot say; I've never seen one before. Here is a pic of it.

Glad you like the 1.6 twinport. I was surprised to read in Haynes that it has variable valve timing, very high tech. I imagine it would benefit from clean oil. My son Jonny likes the sound system too.

The service history contains no mention of an oil change in the last 10 years. So once the oil filter got blocked, and the bypass opened, all the debris in the oil was recirculated. I did observe, and comment on this forum, that whereas after the oil and filter change on my first Astra the dip stick showed clean oil, on this Astra it did not.

I imagine it would have taken several more oil and filter changes to remove all that debris from the system. I should have changed the oil and filter again on seeing that dip stick, and again and again until the stick showed clean oil. Silly me. I shall not make that mistake again.

I would imagine that the oil pick up in the pic needs soaking in parrafin or similar to wash it out ?
Might be best to check with someone who knows these engines though.Then, either a few quick oil changes with cheap oil to clean things out, or run some flushing oil through it, if you can still find such a thing.
May be wrth dropping the sump again after that as it may well be full of crap again.  :-\

Hindsight is a wonderful thing  ;D
strainer still looks clogged up ,backflush it into a container and see what goodies you find  :y
if clogged up ,that would explain the oil light etc
I would try a new oil filter and oil, rather than just write this astra off ,rtv or silicone the sump back and give it a go .
VVT is on later models ,early z16xep just has regular cam sprockets  :y
regular oil changes ,sooner than service interval is money well spent in my opinion .

Actually, now you have the sump off, I would take a peek at one or two of the main / big end bearings. That will tell you everything you need to know about whether it's worth persevering.

If you do, it's vital you mark and keep the bearing caps and bearings  the right way so they go back as they came off  :y

top end cam housings will starve of oil long before the crank though normally
