Hello everyone,
I’ll try to be as informative as possible in order to yield the best advice from everyone here on the forum. Car has beeen driving absolutely flawless for the past 1500 miles. Done a handful of trips that were 100 miles each way, trips around town, and everything in between. I was on the freeway going about 60 the other day and out of the blue developed a noticeable valve clatter. Within about 20 seconds, I lost power and the car died on an off ramp of the freeway.
I can get it to start, but it dies as soon as it does unless I get the rpms up to about 1500 (even then it idles extremely rough as if multiple cylinders are missing and there is clearly tons of lifter noise). Has a full tank of gas, all fluids are reading correct levels, and it’s for sure not a vacuum leak (all hoses are new as of June this year).
About the only thing that I can think of is the oil pump considering, if it failed, it would cause excessive valve train noise. However, my oil light never came on indicating low oil pressure (I verified that light works as well). In the past 18 months of ownership, the only mechanical things left that I haven’t touched are the rotating assembly, oil pump, camshaft, or lifters. I’m open to run some other tests that may help get to the root cause and would appreciate any input you all have.
Best, Chris
