Please help me identify this engine.

Some time ago, I replaced the worn-out 258 in my '79 CJ5 with a crate engine that belonged to one of my dad's friends. It came out of an 89 Wrangler, and is supposed to also be a 258, but there's a few oddities:

1. As far as I know, there were no 258s made in 1989.
2. My intake and exhaust manifolds shouldn't fit on any 258 new enough to have 7/16 head bolts, right? Aside from the valve cover in #3, 1979 parts all work with this motor.
3. It took me all summer to find a valve cover that worked with this motor. My old metal 79 valve cover wouldn't work, nor would the later plastic covers. Ended up buying an OEM valve cover from a (91, I think) 4.0 that worked.
4. I have searched the internet high and low for the casting number on the block, and turned up nothing.



Casting # is 002CL27

The remanufacturer tag doesn't have a company name, but here's the tag:



Tag number is Y153186

Does anybody have even the slightest clue about this motor?

wait a minute the 258 4.2 lasted untill 1990 and I think the last year had a serp belt. So if that might be it. or maybe it came out of a XJ.

I guess that's possible. We put the water pump, distributor, starter, alternator, etc. from my old motor on it, so I have no idea what kind of belt setup the original motor had. I'm just kind of perplexed by this thing needing a 4.0 valve cover, plus not being able to find anything online that resembles this casting number.

Reason is it's not a CASTING number. That's metal stamp. Done externally at any time. Can be serial #, VIN #,inventory # from a salvage yard, probably a job # from a remanufacturer, whatever. Anyway, that # is unique to the engine you have.

Yjs had the 258 in tell 90, at 91 they went mpi 4.0s , and 86-90 258s have 1/2" head bolts. 81-85 had 7/16" head bolts, and yes some late 258s used the 4.0 valve cover. Xjs had a 4.0 in 87 an the renix injection fuel injection. 002CL27 is the date build code not a casting number. I would say it is a 1990 built on the 27th of February. The "C" in the date build code determines that it is a 258. The head is most likely a 3661 casting.

Thank you. Finally some light has been shed.

What do you mean by a 3661 casting?

Casting numbers are just that. they are cast into the block, head, crank and so on, not stamped. The one on your head is most likely under the valve cover. Casting numbers are not a easy way to guess the year as some blocks and heads have the same casting number covering a few years or in tell they made a change to the casting. A casting # looks like this

That 002CL27 is a build date/engine family code.

I can't find it now but I've seen a website or more with the decoding info.

Google AMC engine date codes.
