Keith Browning Posted May 7, 2008 Share Posted May 7, 2008 I haven't disassembled this yet but has anybody run into front crank or oil pump leaks yet? This one is actually dripping now with 74 miles on the clock. Quote Link to comment Share on other sites More sharing options...
DwayneGorniak Posted May 7, 2008 Share Posted May 7, 2008 Yep. Check the front crankshaft snout for runout Keith. Max is .002". I had one that was 004" and cracked the front oil pump cover. Tech hotline knows of this concern and they say that in most cases when the snout is bent, the front seal will walk out of the oil pump cover.

Keith Browning Posted May 7, 2008 Author Share Posted May 7, 2008 Therefore I am potentially looking at a new crank or did they send you an engine? Quote Link to comment Share on other sites More sharing options...
DwayneGorniak Posted May 8, 2008 Share Posted May 8, 2008 Sorry for replyin late Keith. I had the unfortunate opportunity of putting a crank in it. They stock cranks in our Edmonton warehouse if that says anything. And I lost my ass on that job. /forums/images/%%GRAEMLIN_URL%%/crybaby2.gif Have you measured or checked anything out yet?

Keith Browning Posted May 8, 2008 Author Share Posted May 8, 2008 I wrote the Hotline and asked for known issues and advice on this one given your experience. They replied by telling me that they have seen problems with the gerotor covers and seals and told me to replace both. When apart I am to inspect the dowels and the cover and check the crank nose run out. Parts are on order. Quote Link to comment Share on other sites More sharing options...
DwayneGorniak Posted May 8, 2008 Share Posted May 8, 2008 The one I had, was bouncing the harmonic ballancer so bad that the tensioner was rattling like crazy. It sounded like it was going to fly apart. Quote Link to comment Share on other sites More sharing options...
HeuiTim Posted May 8, 2008 Share Posted May 8, 2008 Dwayne, did the balancer look like the one in this video, during lubrication section? 6.4 Movie Quote Link to comment Share on other sites More sharing options...
DwayneGorniak Posted May 8, 2008 Share Posted May 8, 2008 Yeah that was pretty close to how bad it moved around. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted May 12, 2008 Author Share Posted May 12, 2008 Dodged a bullet on this one. Got the pump off this morning and found a nice chunk missing from the front crank seal. WHEW! Quote Link to comment Share on other sites More sharing options...
DamageINC Posted May 12, 2008 Share Posted May 12, 2008 We had a front crank seal leak on a 6.4 as well, had like a hundred miles on it and it was BAD. Seal was all torn up. The new seal came with a wear sleeve. Hmm... Dave Quote Link to comment Share on other sites More sharing options...
Mekanik Posted May 30, 2008 Share Posted May 30, 2008 I had one too. Crank seal, and the pump gasket. Quote Link to comment Share on other sites More sharing options...
