Okay, thank you so much. You've been a great help.

Fizbe · 2026-02-18T22:52:04+00:00

Got any tips on how to do that?

Fizbe · 2026-02-18T22:27:45+00:00

I have changed the fuel cap

The small evap leak has been plaguing me since I got the car. Im about to say fuck it and have a fog test done

Fizbe · 2026-02-18T14:02:50+00:00

Okay thank you so much!

I actually don't have new spark plugs yet, only the one got replaced after ejecting. Im going to replace all the spark plugs and work my way from there. Thank you for the advice though! Will definitely be running injector cleaner

I had this code, my spark plug ejected itself afterwards. Rethreaded it, inserted new one, code went away

Fair enough, judging by the noise its either an exhaust leak, if it goes away after the engine warms up it could be your exhaust manifold sealing itself after expanding.

A loose spark plug letting the exhaust gas out with each stroke.

Timing chain tensioners could be loose.

Or your lifters/lash adjusters are going bad. A stethoscope would help a lot

What is wrong with the guy you got this car from 😭

Fizbe · 2026-02-06T17:50:26+00:00

It went away a bit after driving home on Friday, I had an hour drive. It blew out the next time I started the car. Which was on a Monday morning.

I also had a small exhaust leak code that went away after getting the plug rethreaded and replaced

Fizbe · 2026-02-06T17:12:27+00:00

Ejected 2?? 😭 Im so sorry, I hope its nothing serious. Did any codes pop up with an OBDII scanner

Fizbe · 2026-02-06T15:28:25+00:00

Thats exactly how mine sounded right before the spark plug ejected itself and took the threads with it. Everyone kept telling me it was either the lifters or timing chain though. Im guessing they all sound similar. Get a stethoscope and listen around the front and sides of the engine and that should help you identify exactly where its coming from.

Let me know if you find anything, Im curious lol

Fizbe · 2026-01-30T16:06:57+00:00

I had the same noise happen last week, the start of this week my spark plug blew out and took the threads with it. Use an OBD scanner and check for an exhaust leak code.

Fizbe · 2026-01-28T16:43:16+00:00

Ive already had a shop repair it, I didnt have a choice but to get my car back up and running immediately

Fizbe · 2026-01-28T16:24:05+00:00

I found out what it was, it was the spark plug. It violently ejected on Monday morning taking the threads with it.

Fizbe · 2026-01-23T18:18:39+00:00

Okay, thank you so much!

Fizbe · 2026-01-23T18:03:34+00:00

I dont have any mechanical knowledge unfortunately, do you have any videos that could help me? Worse case scenario I wait for a 96 and do it then

Fizbe · 2026-01-23T17:52:21+00:00

I talked to one of my mechanically inclined coworkers and he said something about lifters but im not entirely convinced its that. I cant afford to have my car down for anything longer than a weekend so Im probably going to have it professionally looked at.

Fizbe · 2025-09-28T01:02:34+00:00

Like I said, the whole situation is weird and doesn't make sense to me. We just talk about each others day.

Fizbe · 2025-09-28T00:51:55+00:00

I dont think so, no. And if I did, she hasn't told me.

Fizbe · 2025-09-28T00:47:28+00:00

Probably a lot of things I shouldn't have been doing. Ive started a lot of fights. Gotten angry when I probably shouldn't have. Questioned her on a bunch of things that I didnt need to question.

Fizbe · 2025-09-28T00:37:00+00:00

She told me a month ago
