thanks Ultra marine,
i am geting ready with my plain wood beam cribs, i order some oak and i got Fresno wood instead its super heavy, i have them cutted and brought them to a new metal worker so i dont wait 2 years. in 10-12 days they will be ready. each cribs may weight 25 kilogs each. Plain Fresno wood, it won't crack said the metal worker even if its like green wood it hasn't dried.
Let see how they come out and if its enough height. i could sleep underneath the car after if i wanted to. Its only 14 cm of height so lifting the car so little won't affect nothing, its not great lifting the sides of a car, one by one you know. specially these, concerned at the exhaust pipes.

 

I use Techron every other tank of gas. I have also used VP injector cleaner ever so often. But Techron is the go to cleaner.

 

after 2 weeks ordering the techron, i was told they cant ship it oversea so i went with one with epa pae? inside
no gumout available too, nothing.

 

I've had good success using Redline SI-1 fuel system cleaner

 

That's interesting. Can you expand on the "good success" part?
