switching to synthetic will increase the chance of oil leaks, but you should still be able to switch if you would like to, in the long run your engine will benefit from the switch

 

alright cool thanks

 

Yes I used +4. And replaced both filters.

I have not looked in side the eng but when I looked at the cap it was covered in yellow foam and another time black gook.

The PCV was changed and sparks are new.

Thanks for the help guys

 

that is normal for the 4.7 and IS NOT SLUDGE, its just moisture that "boils" out of the oil and builds up there (the highest point inside the engine) my truck gets that every winter, just wipe it out before you add more oil

 

Ok thanks

Why does this effect happen?


Thanks for the help

 

It happens because air is mixing with the water. Many in the know call it "snot". There is a Service TSB on how to fix/prevent it. With that said... IT IS NOT SLUDGE!

Here are a few snot photos of the snot (NOTE: not Sludge!) problem on the earlier 4.7s and the TSB to fix it.
