I changed the Timing belt on my 99 Escort Zx2w/82K on it. The noise is STILL There. What is it???? It sounds like GM pistion slap but it comes for about 3 seconds. I don't know????????? Are these 2.0 DOHC motors prone to slaping? Dad swears up and down it's just the solid lifters. and he listioned to it so....? I have moble 1 5w 30 and a MC oil filter. Is it possible that the drain back valve in the MC filters are junk and I'm hearing a "dry" start??? I will switch to a Wix next oil change and pray it goes away/

I use MC oil filter only and it has always had the noise.
I guess I never put the two together...
