Loose Lifter????????

So today I was driving down the freeway, and all of the sudden it started make a loud noise coming from the engine....like a clank...clank...

Few days ago, I changed out the Fram filter with a Purolator. The oil only had about 1500 miles on it (Valvoline SYNPOWER). Didn't have any oil, so I put about some Marvel mystery oil in the filter. The noise only happen at about 50-70+ mph.

Ideas?????????? Thinking it might be a loose lifter. Maybe the MMO cleaned out some sludge and a lifter came loose.

only happening at those speeds? any other noise, loss of power, missing, how long did it last

I did notice a lack of power. Doesn't want to go over 2500rpm.

What made you want to change out the fram at 1,500 miles?

I take it you checked the oil after changing the filter?

How does it idle?

No problem with the idle. Oil level is good. I wanted to change the oil but it only had 1500 miles on it. I have 10W30 in there right now. So I just changed the filter. No oil pressure problems. Was going to change the oil to 5W30 see if it helps.

Not hearing it as much now. I'll drive it tommorow morning, see if it acts up again. Going to change the oil....should I put conventional or conventional blend instead of full syn??

change the oil. Get that mystery oil out of there and go all fresh new oil to see what happens.

Yes. Cheap insurance. Also stick with synthetic oil if that is what you have been running. If the engine was running fine on the origional oil before the mystery oil and new filter then I would go back to that oil and the prior filter and see if things go back to normal. No sense in adding unknowns into the problem by going to another oil and filter. You can always change to a better oil and filter later if that is what you want to do.

Change the oil and the filter, I have been using Mobil1 10-30 full syn since it was born, do what you can to never add any additives to the oil. Frequent oil changes will keep the oil clean and all you lube ports in good shape , also be cautious of oil filters some restrict the oil flow and may cause a slight oil preassure loss to vital parts. If the noise continues do what you can to diadnose, where its coming from, upper or lower engine. also pay close attention to the density of the noise, the upper portion of the block... timing chain, rods, lifters, blancer, rockers, the lower end could get a bit more complicated. Is it louder when its cold? does it minimize or go away when the engine raches normal operating temp?.
first give the new oil and filter a shot. If it dosent go away, I ll give you a few more diag tips. good luck.

HAHAHAHAHAHAHAHAHA!!!!!! :lol:

I found the problem!! Since I don't have a bumper cover on right now, the inner fender was rubbing on the tires and the fog light door was sticking out towards the tires making the noise!! Don't know how I missed that one!! :roll:
