I've got a 97 Ranger 4.0 with 190,000km that's been having some issues lately. I've noticed that it's been burning a lot of oil, and recently it started running awful, throwing a P0305 code (cylinder 5 misfire). I pulled the spark plugs and cylinder 5 was very badly fouled, covered in burned oil. Cylinder 6 was bad too, and cylinders 1-4 were fine. I did a compression test and it looked pretty good, with results ranging from 151-165psi. Replaced the 2 bad plugs and it's running fine again (for now). On startup it's blowing out a little puff of blue smoke, but only after it's sat for about 1h+. Any less and it'll start clear. All of this seems to point to the valve stem seals - anyone have experience replacing these? Is it too big of a job for an amateur mechanic?
Also noticed on startup that sometimes there's a pretty audible metallic rattle, mainly at idle. After revving up a little it'll disappear. It sounds like it's coming from under the engine bay but I haven't been able to nail down the source.
Any suggestions, ideas, or personal anecdotes are much appreciated!
