I make you right but i,m confused now lol . So ACL,s was not the chosen type from factory? Reading the link above suggests the old vandervals were used in cast form which mahle are reproducing instead now . I,ll be still using the acl bearing ( not sure if race or duraglide ) at this point as my engineer has recommended them and also afaik his opinion is the O.E bearing are acl,s. I,ll be discussing it with him tommorow anyway, cheers for the link LHD220turbo
