I keep a piece of 1/4 inch plate steel, about 1 square foot in my truck as a base for the jack. Works to keep them from sinking in gravel or dirt. Even really hot asphalt. Sent from my DROID BIONIC using Tapatalk 2
You can remove all but the two bed bolts closest to the tail gate (just loosen those two) and tilt the bed up. Don't forget the ground strap at the front of the bed on the passenger side and the four screws holding the filler neck in place. Block it up and you should have access to the top of your tank.
I have had the whomp whomp sound out of mine for at least 11 years if not 12. I noticed it when I put my k& in. The day I put it not years down the road.
You can remove or lift up the front of the bed and gain access or drop the tank. I have a 5th wheel hitch and dont have much choice. Dropping the tank does not take long as long as there is not alot of fuel in it.
Can you go into more detail about #6? I assume it was melted? Did you drive it like that? You said in the original post "Now it smokes" which makes me think it didn't smoke before even with the bad #6. More info we can get on what brought it to this point the better
That is pretty easy. Just pull the front cover and make sure the timing marks are lined up. Oh, here is what I have been able to dig up about compression:
New rebuild: 350psi
Good Used engine: 300psi
max allowable variance: 100psi
