Hi, im building a VR6 for boost so im using all ARP fasteners. After installing the crankshaft i notice a slight quiet scrape noise while spinning the crank. I isolated the noise and found that the washers on main bearing cap number 7 are scraping slightly on the crank positioning plate.
The washers hang over all of the main bearing caps but the only place it is an issue is on cap 7.
Has anyone else experienced this before? what do you guys think? grind the edges of the washers down?
i can get a pic up tomorrow
Thanks in advance for any insight
