Here is the story. I recently had a full service tune up, valve covers replaced and oil change. Then about 400 miles later my oil light comes on and a terrible knocking sound comes from the engine I immediately pull it over to a gas station and now the mechanic is looking at it. He said the reason was because there is a lot of gunk build up and the oil screen is extremely corroded causing most of the engine not to get oil and that is why the light came on. Don't quote me word for word but this is what he generally told me. Can anyone explain this or maybe let me know on what kind of trouble I am in. | ||

One more thing, I bought this used a couple weeks ago so I am not the dumbass that went over countless miles on oil changes to lead to this problem | ||

Surprises me about being a '95 instead of a '96... the 4.0 is worse to do it than the 3.9; but, it is the same basic engine, so, it stands to reason...... As you surmised, the previous owner probably was extremely lax about oil changes, just cruised around without ever really working the engine, and I'm gonna guess that they were running regular instead of premium gas..... At this point, about the best you're going to be able to do is to thoroughly clean the internals of the engine. Go ahead and use a solvent to get the baked chunks off the oil screen, clean out the pan, etc. Once the pan is back in place, run it a bit, then change the oil again. With a lot of changes, you can get a lot of the gunk out, but, something more aggressive is probably warranted. I can't recall who it was now, but there's a setup that some shops have that cleans the insides of an engine. It's not like the bottle-stuff that Quick-lube or some place like that would use.... (they just use kerosene I believe), or Marvel or BG44K, etc. etc. Those things have their place, but you want something more thorough than just a couple of bottles of the stuff. This place essentially drains the oil, fills it up with the other fluid, and pumps it through, then drains it and refills with oil. OR something to that effect. Supposedly does a good job. (hmmm...... maybe it was Bilstein, the shock company? It was something like that, a company known for something other than engine cleaning....) Anyway, it's something to try, before having to rebuild or replace an engine. Best o' luck..... -L |
