Ok, so I am passing the echo to my girlfriend and purchasing a z3 or z4.
Her dad said he wanted to have his friend inspect it.
After a year of TLC and some mods the car runs great. cant even feel the engine at idle! (uncommon in these cars I hear)
Well he takes it to the guy and she brings it back. We drive about 20 miles and all of a sudden its bucking at idle, missing and low RPM, all that good stuff.
So I pull over and look under the hood.
The hose going into the side of the airbox is now closed in the airbox and completely crimped. He obviously checked the airfilter and then closed the hose on it.
I pull spark plugs and cylinder one plug is covered in brown sludge. Just dripping.
Could that hose being crimped cause anything like that? also the name of that hose is escaping me, anyone know it so I can do some googling?
The thing that scares me is there was absolutely no progression to it. It went from running like a top to that in seconds.
I pulled the plugs and replaced them with some good used ones I had lying around. Its at least got to get me to work tomorrow haha
If it is a headgasket all I can say guys is the whole engine is being torn down and expect a small turbo build

. I have some 9bs lying around. Would be perfect for this car. Nothing severe but to make it a little more fun
