Drain plugs need a copper washer to not leak; or, you can even get a washer with a rubber middle to seal.next time is nice out ill go under the truck and take pictures . also will take pictures of the engine from above. trying to be detailed so you can help me figure out where its leeking from. I do know I need a new oil pan in general the owner before me striped the pan and put in a larger bolt :rant: . then I did an oil change not knowing that and had to put an even larger bolt in . but the larger drain plug I installed has a bolt in the center of it to drian without removing the large bolt. it looks like it drips slowly from the large bolt but im hoping its just not tight enough. anyways ill be back with pictures soon! thanks :rotf:
I am not worried about the motor. That 4.3 is solid. Crud is from I am better low grade oil from the previous 2 owners what I am thinking. I have RTV on hand. Will use spray adhesive to help stick the gasket. Not that bad of a job with the trans out.Props to you for tackling a challenging job.
As for the cross-hatching on the cylinders seen from below, I trust that you do know that the part of the cylinder (on a non-"stroked" motor) that wears the worst tends to be at the TOP of the cylinder. If visible damage were present at the bottom of the cylinder, you would probably be looking at that cylinder because whatever caused that damage caused the motor to have to be pulled.
Good luck, and be careful, putting it back together. Watch those corners with the pan gasket. Make sure your RTV is good on those corners.
You don't have to lift the motor to pull the pan, but the alternative is a big job, I know I'm in the middle of it right now. I took the whole front end apart and because I did I bought through the internet a complete frontend rebuild kit for $1I0 also suggest that you buy a set of rod cap barings unless yours are like new. So even though it was a lot of extra work and not that much more then lifting a motor witch can be a big pain also. You will end up with a really nice handling ride and this will be all good.On what? i know you dont have to on a kenworth t-800 but you have to lift the motor up on a 4x4 s10, be more specific with what you say.
