driving down to an Autocross Event this Sunday, along the freeway I decided to downshift to 4th, and then motor hesitated and just a sh*t load of smoke; pull off to the side, car would fire up, but run as if it was down on a cylinder. So I got my free AAA tow home Motor is a JDM B18C spec R Today I pulled the spark plugs, ton of oil on the threads. Did a compression test on it I get 245 to 250 psi across all the cylinders. So Im holding good Compression. I called my pops and he has a cool camera, we sent it down and we see some fresh oil on the top of the cylinders 1 and 2. We put a 90 degree mirror on it and we can see drops of oil slowling coming down the cylinder walls. So we are thinking Head Gasket. One thing that scares me is that part of the porcleain from the spark plug broke off. If I damaged the walls would it hold such good compression?
