Hi guys,
I'm new to the forum, I'm going to try and describe the problem as best as I can. I'm going to start by describing the cars mechanical history since purchase then the most recent incident followed by the first incident as it could potentially help isolate the problem.
MECHANICAL HISTORY
I purchased the 1999 Cobra Vert in May with 150,000 miles. The previous owner sold it to me for $3,000 because it had a REALLY loud knocking sound. I have someone take apart the engine and we immediately find large chunks of metal in the oil pan. The mechanic says the oil filter was not properly tightened and that he ran the car dry. After taking the engine apart he finds two damaged piston heads, one broken tie rod, a slightly bent crankshaft, and a small chip in the aluminum block. He buys new rods and piston heads (stock nothing special) and all the metals that go along with them (bearings, rings, etc.). He gets the forged crankshaft turned and fixed along with the block. He inspects everything else and tells me the other parts are in good conditions.
I take the car from LA to Vegas for my bachelor party. I don't drive it more than 70-75 mph. I make it back with no issues. I get married on 7/9 and go on my honeymoon and come back 7/20. I drive the car less than 500 miles after that because teachers don't get payed in the summer (My wife and I are both teachers). I start working again 9/8 and I change the oil for the first time since the rebuild on 9/10 (Mobil 1 5W-30 and a Mobil filter). I see shavings in the oil but nothing out of the ordinary. Then the shit hits the fan...
INCIDENT #2
https://www.youtube.com/watch?v=wckcFuxzdBY
After exiting the freeway this Tuesday morning 9/20 on my way to work, I started to hear the faint knocking/ticking when the car was idling. When the light turned green I revved up to 2000 rpm before switching into 2nd gear and the sound got louder. I hit about 5 lights before I get to work. I heard the knocking/ticking with every gear if I got up to 2000 rpm. I park the car at work and check the oil. It was slightly below max. After work I start the car again and I hear the faint knocking/ticking sound again. I revved it up again to 2000 rpms and it got louder again. Luckily my commute is only 8 miles so I take it slowly again back home.
I get home record the video. Then I ask my dad for some advice and we check the spark plugs we instaled Monday afternoon. They were clean as a whistle. Then he suggests that I buy an additive that stops valve noise and fill up on gas. I pump 91 at Chevron and I drive it 30 miles. When the car was idling it sounded much better, I don't think I could hear the faint knocking/ticking but I could hear could still hear the knocking/ticking at 65-70 mph and/or at 2000 rpm.
INCIDENT #1
Prior to incident 2, this past Sunday 9/18 I went to a car show in San Fernando Valley (Galpin Car Show). When I pulled into the lot I was assigned to, I noticed that it was idling very rough. As soon as I turn on the car to leave the lot my check engine came light on. When I hopped on the freeway I noticed a loss in power. Yay... 45 miles to San Pedro... I drive it gently (65 mph) on the way back home and eventually I make back home with no issues.
Later that Sunday afternoon, and run the scanner to check the code and it turns out I have a misfire in piston #4. I go to autozone and I buy 1 OEM Motorcraft Platinum Spark Plug. I switch them out and it starts running ok. After work on Monday 9/19, I go back to autozone to buy the remaining 7 OEM Motorcraft Platinum Spark Plugs. It runs GREAT after that. Honestly, better than when I got it back from the mechanic when the engine was rebuilt.
Any help would be greatly appreciated. If you need more info/vids/pics, I'll be more than heppy to provide them.
I'll be driving my 1999 V6 Vert to work till the Cobra gets sorted. I'm actually kind a glad I didn't get rid of it during the summer.
