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 .

this is getting rediculous the rumors that are out about oils and change this change that... synthetic can hurt a brand new motor (dont believe me run a boxer engine on syn. for a while and see what happens). The reason i use the boxer motor as an example is because it will fail everytime and for the same reason. syn is too slippery for the piston rings. As for a new motor, it needs to have some metal on metal grinding to properly seat the piston rings. which is actually 95% broke in within the first 50miles (yes fifty miles). so those of u who say baby your motor for 10k miles. thats BS.

ok, aside from my rant.. you should check your oil before 1000miles, by then it could be too late. my question is you said its a rebuild, have you changed the oil on it yet since you started running the motor? if not the metal is normal. if you have, change the oil after a few hundred miles if pressure stays normal and no knocking occurs. then drain it and see whats in there.

but that is how i would go about it. the point of forums is to collect everyone's idea and formulate your own based on theirs. not to take anyone person's word as the truth. (no matter how much they assure you). myself and everyone here included.
