I have been having a issue when i get on the gas it starts misfiring.
i ran diagnostic test and turns out its cylinder 5 and 6.
Note: my coolant tank did start leaking but caught it quick and replaced.
The car runs great no issues until i get on it. then goes into limp mode but resets. i ran endoscope into cylinder 5 and 6 and i will post pics. to me the walls look great, plugs had oil all over them in 5 and 6 and coolant tank i pulled looked brownish but could still see green tint.
it looks like the oil is running down from top of cylinder walls. i am thinking head gasket. Unfortunately i should have ran compression test but i didnt. i honestly dont think its the piston seals. car has 60K miles.
If someone could help me please.

Just Crying to see such an issue on such low miles. 60k? that is just sad.

Hope you get it sorted out.

I would want to rule out the worst post possibilities like a headgasket failure. How long have you owned the car? Are you confident no one added the wrong coolant, which could turn the coolant brown? Has the coolant level been rising? What does the oil look like?

Have you looked at injectors 5 and 6 for signs of coolant residue?

What are the codes? What scan tool are you using? Misfiring in 5 and 6? Have you swapped plugs and coils to other cylinders?

Did you inspect any other cylinders? No oil running down the cylinder walls?

Leak down test on 5 and 6?

I think it's got to be head gasket nobody has touched this car since I owned it for 2 years now. I only put oem fluids in the car. I also replaced expansion tank and their wasn't a problem then with coolant. Using a Ancel FX 2000 and a Ancel BM 700 show multiple misfires and knock detected in 5 and 6. No other codes.it did show low coolant a couple weeks ago I put a quart in. But you can see the oil looks pretty normal. And tank is not cracked or leaking. Going to pull injectors out today. Just got the tool delivered.
