I can believe that there may be no engine damage, but I would still be skeptical!!! After I modified my SRT-4 to over 400HP, the oil pump rotor exploded on a run, I was almost at redline in 2nd gear running @25 psi of boost at the time, when the oil light came on and the dash said, "****"!!! Needless to say, I got out of it immediately and pulled over, shut off the engine and checked oil level and checked underneath to make sure the oil pan hadn't sprouted any rods. Everything looked ok so I started it back up and idled it back to the pits. When I pulled the rod and main bearings, I found to my delight NO DAMAGE!!!! or wear, no play in the turbo! I installed a race oil system from Darrell Cox racing, ****canned my balance shafts, and buttoned everything back up. Now I will say, that being the cautious technician that I am, I followed up my visual inspection by sending in an oil sample to wearcheck inc. I use this company to do all my oil analysis on vehicles that come into my shop. Their report also showed no damage or foreign material that would indicate any internal damage or above average wear to the engine. MOBIL ONE IS THE ****!!!!!!!! I use Mobil One in all my cars and always will, I'm sold on it. The gist of my rant is to strongly encourage you to send in an oil sample immediately!!! They will check the sample to the micron level and also chemically test it to determine if there is any bearing material in it that shouldn't be there. It's well worth the 35 to 50 bucks just for the peace of mind factor!!!! My 2c. ASE L1 CDMAT
