Default Re: Breaking News: New VAG 504.00 & 507.00 standa

Push rod motors are not more costly. Eight push rods and lifters. No need for a belt or all the parts to encase it, tension it or idlers. Some ohc heads have cam brg caps some don't the ohv cam would slide into bores like a chevy low cost. Most ohc use rockers. Over all it would be a wash. Yes I understand the advantages of a four valve head volumetric efficiency. If getting more air into the motor is not necessary than why did VW put a turbo on it. Dan
