Then you need to check with line2line before you do anything. Their coating is meant to wear in. So it must be tight.
Damn I didn't know they were doing stuff like that. My next engine is going to start with l2l coatings on the Pistons and now probably the oil pump.
Everything I've seen shows their coatings work. So check with them. As long as you can turn the engine over without binding it may not be the problem you think it is.
Also, keep us posted. This is very interesting. I like cool technology like this. Now I'm pissed my pump isn't coated.
