When the vibration starts, I put the truck in neutral to coast and it is still vibrating. I was thinking it was either coming from the rear end, hanger bearing, or transmission. I raised the rear end up and rotated the wheels. The passenger wheel rotates freely, but the driver side wheel is a bear to turn. It sounds as if the brake is rubbing on this side more. Also, when I rotate the passenger side tire, the driver side wheel does not move and vice versa. These should spin in the opposite directions when turned. Do you think my brakes are messed up, bad bearings in axle, gears? Anyone have recommendations on where to start? I am having a bad vibration when driving my truck.

My block heater is the factory, and was never once used until the truck moved to ohio about 3 years ago. I used to leave it plugged in all night, and that would be enough that around 30F the fast idle is not needed to start. I now have it on a timer to come on 3-4 hours before i leave, and the fast idle is kicking on some mornings, and its not getting as warm. A friend with a 7.3 could have full heat as soon as he started his truck, with temps in the teens. Is my block heater warn out??

Things are looking up.

The previous owner on this truck adjusted the injection pump and consequently I would like to get a pyro gauge to monitor temperature. Can I buy a guage without buying a "boost kit" I'm having a hard time finding one.

Any suggestions?

Ive got an 86 6.9 4x4. Ive owned it for years , actually ive had several..But i sold this one some time ago and recently got it back. The guy i sold it to played with the injector pump timing and then set it back to factory apparently. Ive noticed a tiny bit of fuel puddling under th intake and when i fired it up it runs for about 3 secs and dies. I notice its a bit gutless now too. My freind has a 7.3 idi and it does the same thing, but if he parks it facing down hill on a good angle its fine. Both trucks are over night problems, and both have had the injector pump played with. Ive heard something about the return lines? Im not an invalid and can fix any part, but before i go mucking about i thought id ask the smart guys first.. Hey,

I can tell it hasn't been used in years. I was reading online that the block is thin where the block heater is installed and the block can crack if you use the heater in the winter???? Any truth to this statement? I am going to be running this truck in the snow (it is a plow truck after all). So do I plug this sucker in, try and start it dead cold, or add an "aftermarket" block heater somewhere in line (or somewhere else). If anybody can clear this misunderstanding up I would appreciate it.

Thanks,

I had very low oil pressure and found that water entered through the top of the engine due to a clogged valley drain. I replaced the rods and main bearings the crank was OK installed a new valley pan gasket water pump,oil pump and oil cooler. I had my radiator flushed and then i ran dish soap through the whole engine and back flushed it. The truck runs great it 45lbs of oil pressure cold and 20lbs idling at temp. the kicker is after the truck sat over night i removed the oil plug and nice clean water came out (about one half quart) before the oil but, its not mixed or foamy. The oil on the dip stick is very clean with no sign of water. When i had the motor tore down i found evidence that something fell down in the oil fill tube there was gauling and the ip gear housing is cracked. i repaired the crack with jb weld but saw no other damage. i cant tell if the gears were changed. There was no damage to the gears. Does anyone think it is possible for water to enter the engine through a crack in the water jacket when the engine is off and not foam up ? i cant see a crack but i dont know what else could be happening. I will be taking the water pump off tomorrow to inspect it closer for any signs of a crack. I saw some water at the bottem of the oil fill neck not much but its there if i wipe it up it comes back. I did not replace the head gaskets i was told that these truck will smoke alot and run poorly if they are bad and since the truck ran well with no smoke i left them alone i should have changed them i know. any ideas would be helpful. thanks Hey guys I need some help. i have a 1985 f350 dump with 95,000 miles.

Maybe half a centimeter. I know the seal on the firewall is hardened and probably does no good. I can see a water line on the top of the air filter lid so I know it can collect there. The truck has been run in about two months. Also I used a pump and some small hose to suck out all the water I could find. I was able to get pretty deep on the passenger side of the manifold Does anyone have any wisdom to share?
