I do not like crank scrapers.
I look at them as a thin piece of metal that can get tangled up in my engines. An accident waiting to happen in my opinion.
Have any of you ever been inside the bottom end of an engine and seen a mark on a crank or rod or on somthing that looked like something hit it? I have seen this and immediately in my mind was the thought of what if that engine was using a crank scraper. That thin scraper would be torn or bent and be mangled into the engine causing tons of damage.
From that day on, I will not use crank scrapers. Guess what I see no difference in my engines by not using them. I also don't miss the cutting and fitting them either. I also do not use the thin sheet valley cover shields either. I look at them as an accident waiting to happen too.
