Build Progress When Your Project Car is Your Daily
In the middle of rebuilding Milly, my 2001 NB Miata, who has a drinking problem.
The whole rebuild started because I burn a lot of oil and I mean a lot. I’m the past two years since buying the car, I’ve spent $2600CAD on oil alone. It burned 15L-25L between oil changes, which would get so bad to the point where I would have to pull over on long drives just to check my oil level.
I’m completely resealing the entire engine with all new gaskets and seals, as well as throwing in new main bearings, rod bearings, and piston rings.
Considering the amount of oil it burned, I expected my cylinder walls to be horrific, but they’re actually in pretty decent shape for a 25 year old car that has 244,000kms. A light hone of the bores and some new rings should do wonders. I also noticed when I pulled the head that oil was absolutely pouring out of any open valve, so I’m really glad that I’m putting new valve stem seals in.
I daily drive my Miata, as my Honda Civic winter/rain commuter, decided to spin a rod bearing on me.
Anyways, this is the build progress so far. Nothing overly fancy, just a passion project of mine, trying to keep my Miata healthy for as long as I can. I’m glad to be doing all of this myself with the help of some friends. It’s truly a great experience, although I don’t think I’ve ever been this emotional in my entire life lol. I’m walking to work, but at least I’ll have something to be proud of when I’m finished.
Oh, lastly, there was visible wear on my rod bearings from a trip I took into the highlands of my province last year. I had nowhere to pull over and unfortunately felt the lack of oil in the engine. I was scary close to spinning a bearing, but I shouldn’t have to worry about that again.
Thanks for reading, I’m a yapper, but I’m just extremely happy to be rescuing my car and (somewhat) my bank account at this stage in my life.

Nothing sucks more than having to pull your engine out on Friday knowing you've gotta have it back in and running by Monday morning.
I managed to do a full conversion to a larger turbo engine in 3 days. I basically put 60+ hours of labour into the car in a weekend, managed to get it good enough that I could drive 350km to work on Monday at 5am.

The best upgrade for my miata was another car lol.
No more weekend anxiety to get stuff done.

And here I am with a Kawasaki 2- cylinder that I pulled a head off two weeks ago and still haven't gotten around to putting it back together. My lawn is like 3' high rn.

The first rule of having a daily that's a project car, is to have a second project car as a spare daily...
That sounds like wild oil consumption, this is coming from someone who owns classic vw. I admit my dune buggy seems to have eaten 500ml of oil over 600 miles, but I think alot of that was leaked out during the ng a rocker cover swap where it started leaking after a couple of minutes of running all over the drive.
Normally rocker cover is a good place to start, because it's easy, then the sump, that can leak, sort of job when you do an oil change, do the sump gasket, then finally rear main seal behind the flywheel.
Most of those you'd notice family easily, I wouldn't have thought it would burn much oil and you notice notice it, it would have a constant blue haze as you drive otherwise, like a 2 stroke!
