Exhaust line cleaning

Last post I talked about the exhaust line need to clean periodically, some can last longer some shorter, all depend on the exhaust pressure gauge reading.

If it drop lower, then it will be time to arrange for the cleaning job.

Today I will talk about the situation when you encountered the exhaust line choking.

First scenario and most common will be like this, white powder with the center only without any powder and the left over suction is through the small hole.

Sometime you also can see powder hardened became the rock pieces. Normally this is heavier as the incident should happened longer and accumulate longer.

The third is a bit combinational. The surface became rough and super difficult to clean away even using metal rod.
