metal in oil and now other things Options

[blckcelica95]

so i need some help on this one today my girlfriend was driving my celica, it ran fine all day until she stopped and shut the car off for 15 minutes , she gets back in and the car wont start, just cranks over. after about five minutes bam the car starts and runs fine. She get its back here and i take a look at it . its running fine no knock. purring like it always does. so i shut it off, and guess what happened 20 minutes later . wont start . so i wait about a minute try again and it starts up. so i pop the hood and start looking around to see what going on. I found that the spark plug wires had **** the bed so changed them. then i decided to change the oil. and i found metal particles in the oil.
Could these to things be related and what could be the metal in the oil. keep in mind the cars oil pressure never drops below 25 psi when running, it has no knock what so ever. and it idle at round 5-700 rpm.
it sounds to me like im chewing up a rod bearing, or main bearing, but it dosent show any other symptoms but these .

i've heard the opposite about synths and breaking engines in. what i've heard is that because the oil is more uniform it fills the cross hatches better and allows the rings more even contact. but its all really moot. engines ran fine and broke in fine before synthetic and engines have ran fine and broken in fine ON synthetic oils too. oil is pretty much oil UNLESS your engine is subjected to extremes. plenty of people who race competitively use their own blends of several oils in their cars because no one oil gives them what they want. others just dump in some mobil1 and call it a day. at the end of the day all the cars went around the track and drove home.

unless its -10 every time you start your car or unless you're turbo charged a premium conventional oil is fine. i choose to run a full syn in winter because the engine cranks easier in the extreme cold with it. in the summer i run a blend, either season i do 5k change intervals or 6 months whichever comes first. usually 6 months.
