Vauxhall 2.0 16v Ecotec engines - what's the difference?

I hope that price was nothing....

Provided the engine code is the same, the only differences will be the sump, and probably the oil pick for the oil pump, which will be interchangeable between the engines.

It was more than nothing but less than 300. Because it's (a) an estate and (b) has a professional lpg conversion. So I have the large capacious car I desire _and_ the cheap running costs I need. When you have three kids with hobbies that involve lots of equipment, and work 25 miles from home, you have to settle for what's practical!

Wuss!

I used to walk that to school each morning. And we didnt have shoes. We had to wear sacks on our feet.

We had to crawl to school, 408 miles, on us hands and knees, over broken glass, wearing sandpaper.

interchangeable

Why do you need a new engine? Would a head change not be sufficient? In any case I believe the only 16v ecotec 2.0 engine fitted to the omega was the X20XEV.

You wus lucky, we had to tunnel our way to school like moles though

The bit about there being four valves sitting on top off the piston crowns (ie. no longer attached to the head) is the clue. Generally this means the valves have dropped and have mashed the top off the pistons, and possibly scored the bores. Meaning a complete engine strip, with the minimum off new pistons, but probably requiring a re-bore aswell. Which is alot more expensive in parts than just buying an engine from a scrap yard.

It was somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember "barry" saying something like:

You had feet? You lucky, lucky, lucky bastard!

Just like in here, really.

The flat sump on mine is 3 or 4 inches, yes inches, wider at the front than the other type. That's a big difference in oil pickup!

What's easiest, swapping the engine, or getting a head, having it skimmed, reassembling everything with new gaskets, and hoping it will all be OK? There are four valve heads sitting on the pistons; they didn't get there after the engine was stripped. I haven't inspected the bores too closely, but I suspect they're scored. Besides, the tax is over a year out of date, which suggests to me that the engine has been in bits for a long time. Not good. Plus it's done over 200k, so the bottom end will need doing too. The cost and time involved is more than swapping it for a good engine.

This is what I'm asking about. There are definitely two very different sump types, though the rest of the engine looks pretty similar. I haven't seen enough of them to detect the differences, but the sump must differ by that much for a reason. I must get another good look at it, but the weather's not too favourable for that right now.

It was that he didn't say there were imbedded in the pistons that made me think maybe they were ok :-)

Probably to do with the fact in the omega there's a front crossmember under the engine.

Well that may be so, but the breaker's yard engine I looked at came from an Omega too. There's something else, but I've yet to find out what.

Are both engines out the same model of omega? I'm sure the newer omegas had the flat (alloy?) sump.

Mine's a 96(N). The sump doesn't appear to be alloy, looks more like the usual pressed steel. The breaker's engine was apparently from a P-reg, but the car had gone, so I don't know what model.

I've just had a closer look, now that some of the snow's thawed. There's a flat extension to the block casting on both sides, about 4 inches wide and probably 8 inches long. Viewing from underneath, the sump effectively runs transversely in front of the cross-member. That would imply to me that the engines are not interchangeable, but I'd love to know why they can be so different in what's apparently the same car.

The only obvious factor seems to be that mine's an estate, but is the estate floorpan so different that it requires a totally different engine block casting?
