Dumb question: Why does it roll backwards on a hill in 1st gear?

[VTCDN]

Time to do a e-brake check and make sure all is adjusted , and no seized rear brake bits.
If you roll into something / body and your not in the truck , Your in the country that breeds snakes, What could just be a scrape , bump , Might turn out to cost more than the repair.

I once saw a car , unattended back into a restaurant I was grabbing tempura for lunch. 2 folks were hurt that were sitting by the front window. Cops , fireman , ambulance all over , 2 hours later this dude is looking for his missing car, of where he parked it. He was arrested in hand-cuffs cuz the over hyped cops thought he was drunk, and backed into the store / shop. He did receive a ticket , plus the insurance made good on his part, ONLY because the front bumper cover had a huge dent and mark where the front was struck from another car backing in and that broke his automatic parking dog , the thing that holds the car from moving while in park.

That could of become very expensive , but since his only failure was to apply the parking brake on a hill , a ticket was issued.

Just a heads up 4 U.

As far as I know, it's perfectly normal. My truck (as will many other vehicles) will roll backwards or forwards in first gear if the incline/decline is steep enough. That's why we have parking brakes. The 3F-E only has an 8.1:1 compression ratio, which is pretty low by modern standards. This makes it easier to turn the engine over, regardless of each cylinder's compression, especially when you're talking about a vehicle as heavy as ours.

As for why you're having to pull the parking brake harder than before to get it to stay put - maybe they need work, or the cables have stretched, or...?

Anyone care to comment whether putting their truck in 1st is enough to hold it in place on hills etc?

Putting it in first gear with the engine off will hold the truck in all but the most steep inclines. With the engine running the incline can certainly overcome the engine and transmission.

That said, and unrelated I think, your compression numbers are low / uneven. Are you using a 'hold in place' compression gauge, or a screw in one? Are you doing a wet test or dry?

The FJ60 has a tractor motor and will run with very large differences in compression, so no need to worry, but with those differences you may notice hesitations in acceleration.

I used a screw in gauge. I warmed the motor up for the first 2 cylinders, but took an hour break then did the last 4. I believe i did the test dry?

I had a shop work on my truck last fall. They did a awful job in everything they touched, the truck was 10x worse after leaving the shop. Since then the truck has had no power, and the engine misses in 3rd gear. Lately the missing has gotten worse especially after driving a while and the engine is hot, missing in all gears on load. Power/acceleration has been severely lacking since I had the truck worked on. Also, on those 3 cylinders with low compression, the spark plugs did not look as good as the other cylinders. Maybe had oily residue on them and could have smelled like oil. They didn't look horrible, just a little different than the spark plugs on the "good" cylinders. I've had the spark plugs out b4 a year ago or so and they did not look like that.

I had that same shop "fix" the oil galley plug on my motor. He tapped it and put an allen head bolt in it but its been leaking since I got it back. I wonder if he could have done something to the motor while he had it.

Anyway I may do a write-up later on this guy and his shop. For now, the shop is called The Cruiser Company in Little Rock Arkansas. The guy's name is Bobby. He was recommended to me from someone on this board. Do not use this guy..he is unbelievably terrible and a crook.

Rerun it wet - here is an interesting article on compression testing:

Check the timing, it could need to be advanced - assuming you still have the fuel injected motor - not sure how you would check advance

Oil on the plugs worries me - makes me think the piston rings are worn - but the good news is that a cruiser will run like this for years and that your lack of power is probably not mostly due to this lower compression.

If the plug is leaking, maybe you can put a rubber gasket in the next time you do a drain and fill.

If I am ever in Arkansas, I will steer clear

Good luck!

Throw a wood wedge block behind your seat........stick it behind your rig when you park, and never worry! Piece of mind....
My closest curb is 140 miles away...
