The effect of Engine Restorer on my 22re
Way back in Feb 2020, i ran a comp test on my 4runner. I tested the engine hot, throttle body not held open. The mileage at the time was about 191k and I know the previous owner had done a headgasket on it and I assume, a valve job.
The results were:
#1, 149
#2, 130
#3, 140
#4, 110
The vacuum gauge shows weak rings and I think mostly that is #4.
In May 2021 I did another hot test, again throttle body closed. The mileage was approx 105k.
#1, 150
#2, 140
#3, 147
#4, 115
Now the mileage is 200k.
I had been running Engine Restorer for a few thousand miles.
Latest test, hot, throttle body held open:
#1, 155
#2, 145
#3, 145
#4, 109
I tested and observed that holding the throttle body open(#1 cyl test) accounted for an increase of 4-5psi.
conclusion: Though I had seen videos of others testing Engine Restorer on YouTube with positive results on lawn mower engines, and that is what convinced me to try it, I cannot prove it did anything for my engine. Perhaps the results are conditional, like it helped minor cylinder scoring on #2 but did not help the rings on #4.
Either way, after recent timing adjustment, oil change, idle adjustment and spark plugs cleaning, the damn thing still runs too good to take it apart!
If you’ve had better results with Engine Restorer, let us know.
