1986 6.2 3/4 Ton. 4x4
I went and looked at the truck I really like and it ran fine,started right up even at 25 Degrees where it was sitting. Motor was stone cold when I looked at it. I found a very tidy clean engine bay. No leaks no smell of fuel and just looked like it had the miles advertised. (140k) Let it warm up until the engine slowed down(I guess a choke system). Ran it up the mountain about 6 miles and turned it around. It smoked (black only up the hill) but hardly at all down. When I started it it ran smooth with hardly anything visible out the exhaust. I had to put my hand down to the pipes to find it was putting out some suet. Drive lines looked real good and the exhaust and mufflers were hardly aged. It is a 4 Speed with Low Granny gear. No play in the drive lines. No rust on the whole truck, it has the 16 1/2 inch wheels and brand new tires. It has a brand new Hydro boost. 2 New Batteries. Only thing is the A/c needs charged.
Now the questions:
1. I noticed when cruising in 3rd gear if I let up on the throttle and then hit it hard the truck seemed to lurch forward but with good power. Almost seemed like the tranny slipped but it wasn't a glunk type lurch. Is this normal?
2. There was a small amount of oil or tranny grease on the tranny bolt. It seemed to be coming from the oil filter area. Couldn't tell for sure. Is this a big problem? Or just a seal? Any help is greatly appreciated.
Edit: Also the Oil pressure gauge doesn't work. It stays all the way to the right and doesn't change. Is this a Electric or manual Gage? Where is it located at on the engine so I can check it.
