History: I recently bought this. 93 4 dr 1.5 all stock, 150,000 miles. Blue smoke on startup and idling. I haven't driven this car past 15 MPH and only two blocks. Donated car, so no previous owner history or help. Car had about a half a quart of oil in it when I got it.

Compression : 1/205- 2/185 dry,195 wet- 3/205- 4/205
No leak down done.

I thought I would do the valve seals since the compression seemed pretty good. I just removed the head and it looks like it was just replaced with a new or reman. All of the intake valves have a lot of carbon, hard with orange,white,black crap on them. Exhaust valves are clean.

It also looks like the radiator , water pump and timing belt have been done, along with the oil pan being off for some reason. The timing looked to be good before I removed the head, I didn't check the valve lash, but they sounded fine.

Suggestions (if you can follow my rambling)????


I have another motor (190,000) I could regasket, but since this head looks so shiney and new, I would kind of like to use it.
Or I could use my 350,000 mile motor that still doesn't burn oil????

 

ANY suggestions on what I'm overlooking, obviously this is apart and I need the indoor space.
Thanks!

 

I deleted my comment. I see your thinking of valve seals too. I'm just really tired after removing and installing my dash last night fixing a water leak.

 

The head looks to be a new one, although it looks like a PM3 head with the b7 cam reinstalled. I even checked the color of the springs on the seals and they are correct.
The only thing I can think of is maybe the head wasn't torqued correctly. It wasn't that hard to loosen the bolts. That's my only explanation for what looks like both carbon and hard water mineral deposits on the valves??But now I really don't want to put it back together and have the same problem, so I'm regasketing another motor that I know doesn't burn oil and I'll save this one for the future if I need it.

Baffled by this one!
