OMG... All the horror stories of how hard it is and troublesome it is to rebuild your vacuum pump. I did mine from start to finish in 2 hours taking my time. No more oil leak from there now. But now I got to get a front crank seal and replace it. I left the power steering pump attached and just yanked the vacuum pump. Man this is such a easy job to do...

 

I'm going to make a write up...

That was my understanding of the job too. Quite easy. Now for the front crank seal, I have replaced a few of them, but not with the timing cover on the truck. I don't know how you would even do it with the cover in place. Figure a couple hours to replace it.

Yeah... I'm going to pull the cover and reseal the gear case completely. It won't both me a bit.

 

Q: MnTom the gear case cover is just put on with silicone (grey) correct?

Did you have to remove the VP too?

No. VP44 stayed in.

 

Yea... I got my seal today and the silicone to do the cover. I figure I'll just pull the cover so I can get a good photo shoot of the gear case and internal parts.

Okay ...so I have a question. The vaccuum pump. Do they get lazy when they start to leak.

Do you find that the vaccuum controls are a bit snappier working now.

Some folks don't mind the leaks, but if it affects the operation of what it controls then it has to be a good idea.

On a side note, I have so much undercoating shoved in there I can't tell if it leaks or not but it probably does.

I've not notice any changes in vacuum just the oil leaking.
