So furthering my previous thread about my mayo in the cap, i bought a compression tester kit and tryed to attempt it today. Problem: i couldnt get the socket to the spark plug because it wasnt deep enough to go over it. However, when taking off the coilpacks (i think) i found 1 with wet oil on the end (2nd from left), and 1 with what looks like dryed white stuff (far left). I did turn the car over for around 10 seconds while i reversed it. So might this be more certainty that it is a headgasket problem, and if so where should i buy a new kit from or should i just let the garage sort it out and purchase it? ALSO, i tryed to remove my bumper to fit the new headlights, and ALL 3 of the torq bolts were totally stuck and i rounded off the heads. i did spray them with WD40 first also. so any ideas of how i can go about this? thanks all Fresh oil one on top and dryed white stuff bottom. below you can see the wet oil inside. none of the other ones had this oil on them, only this one.
