87 DX engine burning oil - Rebuild or replace?

Postby DaraSue » Tue Jun 13, 2017 3:07 pm

So my car didn't pass emissions last time, and my mechanic says it's because it's burning oil. I'm going to get a 2nd opinion because the car is older than he is, but I want to figure out what my options are.

JDM doesn't appear to carry engines for the gen 1, and the ballpark figure my mechanic quoted me was around $5000 for a rebuild. Has anybody had any luck with either something like Rebuilt Crate Engines or getting a junkyard one?

My car is pretty much falling apart anyway (body rust & cracks, noisy trans, other random stuff that goes wrong after 280,000 miles) so on paper I'd probably be better off just getting another one and using it for what parts are still salvageable but I've had it for 20+ years and it's been the most reliable car I've ever had so I'm reluctant to let go of it. The engine still isn't that bad, it's not smoking heavily or anything yet. But there is a noticeable burnt smell after I get home from work (about 12 miles on the freeway). What are the chances that this could be solved by something less extreme than a total overhaul or new engine?

I've got it registered as vintage for now so I don't technically need the emissions but officially I'm not supposed to use it as a daily driver with that tag so I'd like to figure something else out before the snow starts falling.

It depends on why your engine is burning oil. For example, you could just have valve guides that are worn; they cost MUCH less to replace than overhauling the whole block. I'd try to get it diagnosed, but burning oil can be tricky to hunt.
I got a new shell, just need to stop driving the DX so I can work on it.

I've got a filter for my mouth, it just isn't a good one.

Well, I took it in for a 2nd opinion from a classic car specialist today and unfortunately it was as bad or worse than my other mechanic thought. One cylinder wasn't putting out any compression at all and the other three weren't so hot either. On the bright side he thought the transmission noise was just something in the clutch (something... ring? I think it started with a T) so maybe that's still solid. He thought he might have a line on a junkyard engine with less than 40K on it so we'll see what happens.
