1GR-FE typically a noisey motor?
- Thread starter videopuppy
- Start date
I've never done it on my 4Runner because I've never been concerned, it's loud and makes noise no doubt. But if I was curious about it, I'd just listen to the injectors or the valve cover areas with a screwdriver to the ear to isolate where it's coming from, it would be obvious.
Save the trouble.
The 1GF RE has a lot of valve train noise. Steel chains, running 4 cams, hydraulic lash adjusters, and 4 valves per cylinder . It also, has the variable cam timing solenoids doing their thing too.
Playing around with engine oil weights MAY help quiet the valve train, but it will do nothing to silence it.

Toyota's 1GR FE in the 4Runner does not have direct injection. It has port injection.
I stand corrected, I mis read my source material that stated the engine has "direct ignition" (coil on plug)
My brain read that as direct injection.
Thanks for catching the error!
None the less, they are still noisy.
I agree totally, but I was just stating (maybe the obvious), that if you have concern that it's a quick way to understand if something is awry with a certain component.
With these motors, I have very little concern myself, for better or worse they do make some noise :laugh:

I’m running 5w-30. No noticeable difference in sound (or MPG or performance).
This V6 does not make a beautiful noise but hopefully it will do it for a long time.
All you guys must have short memories of previous rides. My 80’s VWs would shake so bad at idle you could not see out the rear view mirror. I bought a Honda as my next car and was eternally grateful it had a starter lockout when the motor was running because it was so smooth and quiet in comparison that I kept trying to restart it.

Pretty sure this is the same motor that is in the 4th gen as well. Before I knew they were just noisy, I took it to 3 different shops figuring SOMETHING was wrong. Lifter click, noisy injectors, valve train problem... Nah. They are just noisy.
My new to me '18 sounds like a god damn diesel when it is cold.
I guess I'll just get used to it. It is alarming as a new owner.

FJC, 2nd Gen Taco, 4th Gen 4Runner, 5th Gen 4Runner.
The 5th Gen 4Runner gets the most powerful version.

Before my 2014 Trail, I had a 2002 Taco with a 3rz in it. That thing would knock like crazy on a cold start. I sold it with 220,000 on it and I still see it in town today. I really have no noise complaints with the 4.0L in the 4runner.

The Single VVT-i 1GR-FE in the 4th gens, is almost entirely different from the Dual VVT-i 1GR-FE in the 5th gens.
The Dual VVT-i 1GR-FE has a different block, crankshaft, pistons, cylinder heads, intake and exhaust manifolds, etc.

I will say that the oil used does affect how loud the engine sounds at idle. I just recently switched from Mobil 1 "Fuel Economy" to Valvoline High Mileage w/ Max Life and the engine is noticeably quieter at idle.
They are two different viscosities. The Valvoline is 10W-40 and the Mobil 1 is 0W-20, and synthetic to boot. A thicker oil will always make an engine quieter.
You only need to change to a higher viscosity if your engine is using oil. Also, the difference between normal oil and a "high mileage" oil is additives to soften seals than may have become hard, and thus may leak.
Synthetic oils lubricate better and last longer than regular (mineral) oil. Thus, the oil change interval for synthetic oil is twice a long as for mineral oil.

Thicker oils may quieten an engine, but digging deep I've seen that they can cause issues with the vVTi system in these engines.
While I won't give 2 cents for their dealership service depts. - I will give Toyota engineers the nod for their oil recommendation - in this case - 0W-20.

Exactly...our same engines are specified to use up to 20w-50 in other parts of the world.
I'm currently running 5w-30 and have some 15w-40 waiting in the wings for summer use. Planning to do a UOA (Used Oil Analysis) and see how these different grade oils affect wear.
Not so. I specifically looked up "Valvoline High Mileage w/ Max Life" on the Valvoline web site and it stated clearly that it was 10W-40. Valvoline does make a synthetic oil but it is not Valvoline High Mileage w/ Max Life.

Valvoline does make a High Mileage w/ Max Life Full Synthetic in 0w20....

I would worry if my engine stopped making noise. I've found that my engine gets louder somewhere between 5000 and 7500 miles post oil change, so I change mine every 5k or so. I also noticed different brands (I've tried a ton of them) all vary in length from oil change to noticeably louder engine. For instance, Pennzoil for me got louder around 3500 miles.
After my period of trying different oils for the hell of it, I ended up going back to Toyota oil OEM and was able to get the dealer to sell it to me for the same price as M1 at wally world. Also, they always give me the crush washer free with the oil filter. These were my observations.
