Thread: White smoke from exhaust and oil filler (TD5)

Thanks for this, unfortunately I think this is the problem.

If it were residual oil in the exhaust I doubt there would be as much smoke under load and it would not account for the significant loss of power.

I like learning and gaining experience but not the inconvenience. I only have myself to blame though, I shouldn't have been driving that hard on an old engine. I won't drive it over 120 again and I will not keep driving once I see smoke (the power loss happened 5 minutes after the smoke began)!
