Here is sample of the oil I drained out. This was poured out of the oil change collector so was on the top. after settling for 24 hours.

I am trying to drop the sump. I have removed all the bolts and screws I can see attaching the sump to the block and the bell housing, but it did not fall off. I hve given it tentative taps with a hammer, but it stays put. Is there a trick to release it?

Probably glued on with instant gasket - it was a nightmare to get sumps off the 1ZZFE in the MR2, usually needing a chisel or wide scraper and a lump hammer!

scrape part of the gasket out with a Stanley knife, then pry the sump off with a nylon wedge in the hole.
You could knock a screwdriver into the gasket and pry the sump off that way. But you'll probably have to straighten and or dress the edges afterwards.

.. and re-bore it, replace the main and big end bearings... ;)

'Drop the sump' sounds trivial, but it's not. Even removing the front exhaust took a while, and involved blowtorch and angle grinder. I believe I have now removed all the sump retaining screws and bolts, but the sump has not fallen off. I am only doing this to inspect the oil pickup strainer, the car is scrap.

I shall pause at this point. I need the garage for other jobs. Jonny is here this weekend, I must remove the rear wheels froim his Astra.

Here are all the screws and bolts I removed.

Thanks Dave. I have found 2 more screws, left hand end, in tunnels, removed them, tapped sump with hammer and off it fell.


Looks like I was using tar as a lubricant.

Here is the sump. I presume the soft bit on top is the strainer.
