Geo engine replacement. 2 Questions

You would have to check, but I'm pretty sure the 1995 Geo Metro had the OBD I system, while the 1996 received the OBD II. If I were you, I would call around to whatever shops you are considering, and ask them about the engine swap. Or, wait here and a let others give you ideas.

I checked in USA nationwide via

They show that the 94 and 95 should interchange, but no 96 interchange is shown.

That doesnt mean it cant happen, but is an indicator you really need to check deeper before purchasing that engine.

I made an error on the year. My lead is a 1998 1.0 3cyl to be installed in a 1995.

Sorry about this.

My reference

showed no compatible engines other than for the

94 and 95 series. This does not mean a 1998 wont work, but is strongly suggestive that there can be a problem.

Will it physically fit? YES. Will it be a direct drop in? NOPE. Different engine controls and OBD standards make it a PIA to do.

Depending on where you are there are LOT's of the 95 version available CHEAP!

My questions are: 1) Will a 96 work in a 95? 2) Is there an issue if the engine comes from an automatic car to be installed in manual?"

*********************************************

You don't say how many miles the engine has, but oil consumption is often merely a valve guide seal failure, rather than a call for total engine rebuild/replacement. Also, I agree with another poster regarding the feasibility of putting an unknown engine in a vehicle, and thus dealing with (fighting with) the inevitable, inherent compatibility issues... versus simply performing the necessary repairs on the existing engine, which is still intact, servicable and correct -- while possibly not spend much more than you would buying the other (read "wrong") engine. Remember, any and every discrepancy between the old and new engines will have to be dealt with, $$$.

As an aside, IIRC back in the old days, when most cars had carbureted V8 engines, you would sometimes see two similar cars and engines -- and the one with an automatc would have a different cam and manifold combination versus a car with a stick

Many modern engines use a different EGR depending if the application is an automatic or manual trans, which could cause problems in your case vis a vis how it interfaces with the ECM, you could have a check engine light come on all the time, etc... that's just one example. I try to avoid stuff like that wherever possible. Why borrow trouble? It's always best to just repair the extant engine, when it is still intact and servicable..
