Yesterday, my dad and I finally got the chance to do the compression test on the Toyota Starlet when mum did not have to use the car in the afternoon. This was the 3rd test that we did. The 1st was done before the Certech Gel was added, the 2nd was done around 1,000km after the gel was added and yesterday’s test was done about 6,660km after the 1st gel was added.
In the middle of using the gel, the car had to have its oil pan removed and gasket changed and it was weeping oil from it. The 6,660km that I mentioned above was run with Certech Gel still in the oil. The car continue to run about 2,000km after the repair before we were able to do the compression test.
The figures we got yesterday were as follows:
- Cylinder No. 1st Test 2nd Test 3rd Test
- No.1 185 psi 200 psi 180psi
- No.2 150 psi 150 psi 180psi
- No.3 150 psi 170 psi 180psi
- No.4 140 psi 180 psi 200psi
It looks like there was generally an improvement of overall, especially in cylinders 2 to 4. We are not sure why there was a drop in the 1st cylinder’s pressure. Maybe there seal of the compression gauge was not too good when we did it yesterday.
So there you have it. Seems like the gel probably does work. Is there anyone else out there who has used this product? Please share your experiences.
