fusioND Posted February 19, 2015 Share Posted February 19, 2015 Hello Fusion Forum, I'm new to this site as a member, but I've visited it frequently over the years, always great advice here! I have a 2007 fusion v6 FWD w/ 126,000 miles on it. I've always made an oil change within 5,000 mi and roughly 75% of the recent miles were long highway trips on cruise (100+ mi). During my last 2 oil changes (Aug 2014 & Nov 2014) the techs told me that I had very small leaks showing up on the engine, though I had not noticed any spots on the floor at home when checking. I tried a Stop Leak engine oil additive at 123,000 and by 124,000 I started seeing spotting on the garage floor. Now there are a few more spots and I took the car in to the shop to find out what's all leaking. I asked around and found a shop that was highly recommended by a vehicle fleet manager because they don't BS anything. According to the shop I have these oil leaks: - Both oil pan & gasket - Front crankshaft seal - Rear crankshaft seal - Camshaft seal They said they needed to pull the motor to fix everything and the bill would be roughly $2500, they did not recommend fixing it, but rather cleaning it and trading it. Which I'm now inclined to do. This car has spent it's entire life in harsh Minnesota and North Dakota winters, and has generally had 10% ethanol gas in it (it's almost impossible to find straight gasoline anymore here in the plains). Any other theories (besides the ethanol and cold weather factors) on why all of these went bad all at once? Thanks! 0 Quote Link to comment Share on other sites More sharing options...
mozz Posted February 19, 2015 Share Posted February 19, 2015 Has the pcv system been checked? That will blow out your seals. Never use seal fixer or trans fixer or radiator fixer,they are a bandaid. 0 Quote Link to comment Share on other sites More sharing options...

Never use seal fixer or trans fixer or radiator fixer,they are a bandaid. No there was no mention of the PCV system according to the guys I talked with. Could you briefly elaborate on how the PCV system would cause that? And therefore if that is the cause, I assume the seals are toast anyway then...? 0 Quote Link to comment Share on other sites More sharing options...
akirby Posted February 20, 2015 Share Posted February 20, 2015 The V stands for Ventilation - if it's blocked pressure builds up in the crankcase and blows out the seals. 0 Quote Link to comment Share on other sites More sharing options...
mozz Posted February 20, 2015 Share Posted February 20, 2015 Pcv valve and hose should be checked. On the Escape with the 3.0, same motor i suppose, the pcv hose is known to collapse. It's no easy fix as i think you have to remove the intake manifold to get to it. The seals may still be good but the gaskets most likely have pieces missing or split. Only other thing i can think of is the oil pressure relief valve is stuck on the pump causing excess oil pressure. On the good side, it may just be 1 seal or gasket and the oil is spreading out all over making it seem a lot worse. maybe have it pressure washed or steam cleaned to help pinpoint the source. How much is it leaking? Does the dipstick level go down? 0 Quote Link to comment Share on other sites More sharing options...
