Please complete the following information:

• Forge Version: 14.23.5.2847
• BuildCraft Version: 7.99.24.4

To Reproduce
Steps to reproduce the behavior:

1. Place a BC engine
2. Break it / run on top of it
3. See missing texture particles

This is also the case for pipes, but only when you run on top of them it seems.

Fixed in BuildCraft 8.0.0
