Dennis Posted December 21, 2013 Share Posted December 21, 2013 I am looking for a turbo spacer which is used when adding a Jake Brake system in order for the turbo to clear the valve covers. Once the Jake brake set is added with the valve cover spacer the valve covers will hit the turbo unless a spacer is added. I have a Schweizer 550 turbo on my engine, which is an ENDT 673.

Superdog Posted December 21, 2013 Share Posted December 21, 2013 is that the big watercooled turbo? Quote Link to comment Share on other sites More sharing options...
fullfuel01 Posted December 21, 2013 Share Posted December 21, 2013 I'll guess just a plain 237 with the old type manifold that make the turbo stand on it. I think MR model used a different manifold like superliner and MH Quote Link to comment Share on other sites More sharing options...
rsb502 Posted December 22, 2013 Share Posted December 22, 2013 Yeah I thought it was a different exhaust center section that set he turbo at a angle to clear the valve covers not a spacer. But I don't know much about the older Mack 6 cylinders.
