I bought a 2007 sky redline a few months ago. I have added new intake, charge pipes, exhaust down pipe, and a tune from RPM Motorsports. The car has 63K miles on it.
The car was a bit noisy on start up and then quieted down after running for a few seconds. A mechanic at the local garage where I got the car inspected suggested I add Lucas oil additive when I changed the oil. I did that, and after starting the engine it made its normal initial noise, then quieted down as usual. Then it got noticeably noisier, the oil light came on, and I shut the car off. Long story short, I have not seen oil pressure since. I drained the oil, removed the filter, and put in new oil without the additive. I poured the oil through the filter housing. I saw no problem with the filter rand reinstalled it. I have disconnected the coils and rotated the engine with the starter for 10 seconds to attempt to build pressure. I have done this multiple times over a couple of days. I started the engine again and still no pressure. I don’t think I have caused any damage yet, but I am not sure. The engine has run without oil pressure for a total of about 15 seconds. The additive was Lucas, and was very viscous. After I put in the oil with the Lucas additive I didn’t start the car for several days. I theorize that the additive didn’t mix with the oil, sank to the bottom of the pan, and on initial starting was pulled into the pump. I think that perhaps I blew a seal somewhere.
I would like to get any opinions on what the cure to this problem might be. I didn’t purchase this car as a project and I am mulling over whether to sell it as is and cut my losses or attempt to repair it.
