Hello everyone, I just signed up and could use some help.
I'm having a serious problem with my 2002 Intrepid SE, and I'm afraid she may be a goner, here's my story...
The car was owned from about 20k to 98k miles by my brother, who claims he ran it with synthetic oil (so I've come to learn), I've owned it since then (currently at 128k). I have not had any known engine issues with the car but recently did an oil change and went with a synthetic oil instead of conventional. I put in 5w-30 Royal Purple with a RP filter. The oil light has always flickered (mostly at low RPMS) even after oil changes and changing the oil pressure sending unit, but it had come on and stayed on longer than normal while driving this past week. Temperature was fine, no weird smells, no weird noises, car actually seemed to be running best and I checked for leaks and did not see any. Anyway, I'm almost home, and I turn down the radio and hear a very faint noise, sort of sounds like a knock, but not sure. I then hear a loud noise and I basically coast home, though the engine is still turning. I immediately shut it off, still confused as to what just happened. My father has looked at the car, though I'm unsure what he has done. I believe he checked the oil pressure and determined that the engine is not receiving oil, and has called for a slew of parts including oil pump, oil pan gasket, timing chain, and some other stuff. However, he has not dropped the pan or took the engine apart. I'm concerned with ordering these expensive parts without knowing if it will fix the problem or not, and he's getting older and does not have any way to protect himself from the harsh weather outside, so ripping everything apart really just isn't going to happen. He's also blaming some of the problem on using 5w-30 synthetic oil, and insisted on putting 10w-30 conventional in it, but that solved nothing.
Sorry if I sound like an idiot who just destroyed his car, but does anyone have any thoughts? I've basically accepted that this thing is toast, so just give me the straight talk. Any input is appreciated.
