Re: intermittent black smoke

Is the wiring / routing OK (not touching exhaust etc...) or loose ground connection(s) @ the intake manifold (near fuel pressure regulator).
The only times I have seen timing change was a loose cam pulley bolt (7A) or ign timing on a 1980 5000T with a 5 window reluctor wheel (not a single window unit like the 3B) in the ign distributor would rotate / spin on the shaft.
For sure check & monitor your fluid levels.

Good luck, Randy

Sounds like turbo seals, check the oil level soon.

Hi all,

For the past 3 days, I have been driving along fine on the highway when all
of a sudden, the engine loses power a bit, hesitates, and clouds of black
smoke are clearly visible... the back of my car is now all dark from it.
Then it goes away like it came, power comes back, pedal response too...

And a few minutes later or 20 minutes later it starts again... power drops
but speed stays around 50-55 mph. When it is smoking like that, if I try to
accelerate, there is no throttle response, just more smoke... until all goes
away and it is back to almost normal...

any ideas? could it be timing related? TB was done almost exactly 60K ago
