Reduced Engine Power on a 7.3L
I'm new to working on diesels but have a horrible hunch based on codes that are coming up when it's scanned. I started the truck this morning (2008 F350 6.4L powerstroke, not 7.3L like I said in the title) and it had a puff of smoke that I've never seen, then the "reduced engine power" warning came up so I shut it down. Scanned for codes which resulted in P2455 "particulate filter pressure sensor A" (not overly concerned with that one); P252F "engine oil level too high" (big concern since I've not added any oil); P0281 "cylinder 7 contribution/balance (big concern) My fear is that I may have blown the cylinder head gasket some where near #7 which may account for both the balance issue and coolant leaking into the oil causing P252F. Any help on this would be greatly appreciated. My path ahead for now is to drain the oil and check for water contamination. Check the coolant level, If it's a small failure in the gasket I wouldn't expect much transfer but I'll soon see. Thanks again for your time and advice.
