I just recently changed my oil myself for the first time in my 88 lincoln
towncar. I usually have the quick lube places put in 10w30 but i heard that
10w40 was better for the 5.0/302 engine. So I replaced the oil filter and
added 5 and a half fresh quarts of 10w40 oil. Started fine and runs fine.
But while the engine is running, mostly when its idling, i hear this faint
scratching noise in the background. Its not in a rythmic pattern. Its
rather sporadic. I have no idea what this is. Also, it never has done this
before this oil change. I dont know if this will help but these are the
steps I did in changing it...
Drained old oil
dipped my finger in the old oil and spread it around the o-ring a couple of times
Screwed it on and plugged the pan back up and added the 5 1/2 quarts...simple enough i guess but I mighta screwed it up somewhere
Hi, those older Linc.TC"S have two(2) drain plugs on them ,one in the front of the pan and one in the back of the pan , which one did you drain ? You need to drain BOTH, check your oil and see if it shows overfilled.also take a look at your belts check and see if you might have gotten a drop of oil on them . good luck Slim
