Hey everyone I'm new on here my 06 type s is making a grinding noise ONLY on cold starts for about 2 seconds it is NOT the starter I put a brand new one in and it still grinds my mechanic did some research called like 6 acura dealerships and discovered it could possibly be the oil spool valve? He ordered the part and is going to put it in a few days. Has anyone had this issue with replacing there starter and it's still grinding? I would really appreciate some help from anyone. Thank you!
