Hey guys, I've only had my R33 for week now, and it's already giving me headaches.
I was driving perfectly without a flaw for the first couple of days that I had it, but then I started having mis firing issues in mid range and in high range. I changed the spark plugs myself to irridiums, and it got rid of the middle range mis fire but I still have high range mis fire. Anyway, thats not my query, I'm just letting you know what I have mucked around with.
My car is pretty much stock. after market cat back exhaust and pod are the only mechanical mods. So anyway, the day that I changed my sparkplugs, I was driving at night, and I could have sworn I ran over somthing. If I didnt run over somthing, then somthing just went bang in my engine. After this Bang my engine still runs completely fine, but I get this ticking/scraping/grinding noise coming from where my turbo is. I am a noob with skylines/engines ,but I'm gussing somthing that spins in there, is grinding and I have an exhaust leak or somthing. But I cant smell exhaust fumes from the engine. My car still runs fine, and boosts the same as before, plus I still have the misfiring issues.
I'm going to take it to a mechanic on Monday, so I guess these are my questions. Is my car alright to drive on the weekend? Do you know what the problem is? Does this look like a big problem? Is it going to be expensive to fix?
Below is a YouTube link to a video I took of my engine noise.
Thanks guys!
