was driving to my gf's place when all of a sudden i felt power loss. pulled over and did a ghetto compression test and NOTHING! no woosh sound at all coming from the front rotor car was running fine (i just bought it)
i did replace the spark plugs today and put some marvel mystery oil in it.
blown apex seals? fawk!

 

sounds like 2 apex seals busticated.

 

Did you replace the plugs before the failure??
