cbriggs Posted October 15, 2010 Share Posted October 15, 2010 Just thinking out loud here, but has anybody else been noticing a pattern with hp leaks? It seems that every small leak in the lower part of the system (stc fitting or ipr oring) makes a long crank (or no start) hot, and every small leak in the top of the system (dummy plug) creates a long crank cold. I thought it was a characteristic of a dummy plug leak to make a long crank cold, but i fixed one today that had a leak from the icp block off plug on the left hp rail. It had about a 10 second crank cold, and an instant restart hot. What are you guys finding? Quote Link to comment Share on other sites More sharing options...
BLittle500 Posted October 16, 2010 Share Posted October 16, 2010 I've personally had two dummy plug issues both causing no-start hot with no issues cold. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted October 16, 2010 Share Posted October 16, 2010 I've personally had two dummy plug issues both causing no-start hot with no issues cold. That is the most common symptom of high pressure system leaks now, most predominantly the dummy plug o-ring issue. The STC fittings can also commonly show these signs and not just the sudden stall and no restart. Quote Link to comment Share on other sites More sharing options...
Aaron Posted October 18, 2010 Share Posted October 18, 2010 Last long crank concern I ended up with had an aftermarket oil filter in it that wasn't closing the drainback all the way. It would sometimes crank forever, sometimes start, stall then take forever to flash back up, or sometimes act normally. That's the first thing I changed, drove it around for 3-4 days, and never had a repeat issue. IPR was real low, and I couldn't hear any air leaks. Haven't seen it since for a start/stall concern, just oil changes now that he's learned the oil filter from us is the same price as the aftermarket one, now that he's bought the $60 cap Quote Link to comment Share on other sites More sharing options...

Jim Warman Posted October 18, 2010 Share Posted October 18, 2010 Amen... Adam had one where some enterprising soul carved the NAPA Gold filter out of the cap and installed a Ford filter INTO THE NAPA CAP..... These earthlings... they can be ever so funny.

Seen that a few times too!! I personally tried removing the filter from the first napa cap I ever saw......I deemed it "not possible" after fiddling with it for several minutes and went about putting the stock cap/filter back on it.

Ya, I worked on an 03 recently that had the same deal, a napa cap with a Fram filter (looks just like a ford one, with way less material) jammed in it. I showed the customer and he said he has done it like that since he bought it.... 80,000kms ago. I have never seen oil that black in a 6.0l.
