Originally posted by crashz: Funny you should ask this, as I've never seen or even heard of it. Not as common as one would expect when you think about it. I have heard of an older gentleman who decided 4 qrts was not enough for his Buick Century and filled the crankcase full of oil. Right to the top of the valve cover! I thinki this it the only oil related engine failure I've ever heard of.
quote:1991--- a 1990 full size Bronco with a 351 drove (!) into our shop with 31K miles. Factory gray-colored oil filter still on it. He received a new engine since he "didn't know" that he "had" to change the oil at any given interval. To top this all off, the owner worked at the local assembly Ford assembly plant. To this day, I've never seen more sludge in a motor than THAT one. Other than the owner's incompetence, I've never seen an engine come in the shop due to oil related failure...

quote:Those along with other engines of the era used down draft tubes for crankcase evacuation . A engine using that type system would have difficulty efficiently removing the lighter hydrocarbons unless driven mostly at hiway speeds . The advent of the Positive Crankcase Ventilation System " PCV " greatly improved both emmisions and light carbon under the valve covers . Better motor oil came with API SE in the 70's
Originally posted by haley10: Many years ago. 1965 Ford with 289. Severely sludged at 50,000 mi. It was necessary to do a partial teardown to clean it up. I attribute it to 10W40 motor oil easily breaking down. It had been changed regularly with QS SuperBlend. This engine was a mess. I knew the owners and they did change it.
quote:I wouldn't be too sure on that. I think I had 140K on my Pontiac Phoenix with likely the same engine when I traded it at 11 years old. Mixed short trips/long trips, some below 0 winter weather, 6 month OCI, mostly Pennzoil 10W-30 dino, and AC/Purolator filters. I did have a sludge problem, but I blamed that on using Quaker State for a few years. I can't swear I never used a Fram filter on it either. I did put the Grand Am that replaced it on 3 month OCI and eventually went to the recommended 5W-30.
Originally posted by oilyriser: 1982 Olds Omega, V6, 2.8L? -- camshaft wore out 2500 miles past warranty. why? probably from using the recommended 10w30 oil, instead of 5w30. The manual said it was ok, even in winter, but the engine knew otherwise.
