Sprinkle peppermint oil throughout the engine bay ... they don't like the smell.
And I just bought 4in wide black gaffers tape to fix-up the appearance of my insulation. Litterally just put in on today, have no idea how it will hold up.
Lol phone says drivers side is 3dB louder when I hold the phone over drivers side vs passenger side. But theres also an airbox in the way on the passenger side. NOT the best way to measure this. I think the video audio was actually surprisingly representative.
Brief history of cooling system:
I bought car at 210k. It already had a new(er) radiator installed. I observed the heater to blow cold. I had heater core replaced & after the heater worked. Then plugged up again within a year. I asked a dealer to flush. No luck. Paid an Indy toyota shop to...
And here's what started this whole mess in the first place. My exhaust tick. As I heard the tick getting louder over last few years, I thought the crack was getting worse, but in reality I guess my sparkplug #7 was slowly winding itself out of the block.
Reman with blue bolts:
Original head after rebuild. Note I've consistently used non-synthetic oil every 5k miles. Shop used synthetic this time.
What is this pink crap!!?? I've spent soooo much time trying to clean up my cooling system. Multiple flushes previous to this photo. My gosh.
But...
Update:
I had my shop pull the heads.
New OE exhaust manifolds.
Drivers head (with blown plug) was replaced with a reman head.
Passenger head was pulled and sent to a machine shop for rebuild. Surfaced to match reman head.
Starter replaced with Denso Reman.
Injectors replaced with Denso
Coils...
Just had heads rebuilt and my engine runs loud now. New gaskets. I want to pull the valve covers and check valve gap. Do the gaskets need to be replaced when I do that?
Ya know, I think I probably ran the engine about 10 minutes "in that condition". If you look at the marks on the piston, looks like about 5 taps between the electrode falling in and getting ejected.
