Gasket refresh?

[gungfudan]

So my water pump failed on my 94’ B3000 after installing it 15 months ago. So I am changing it out today and I find out that it is leaking behind at the timing chain cover and the driver side head casket is delaminating. The engine has just a little over 72000 original miles on it but it is 25 years old. I would get it all now and change it but I leave tomorrow for Arkansas for work. I absolutely need to work because offshore sucks right now and I have not been offshore in 2 months.

should I go ahead and replace all gaskets from the bottom up when I get back?

Timing chain cover gasket on the 3.0l Vulcan is a pretty common coolant leak point

But not sure what "driver side head casket is delaminating" means?
You can't "see" the head gasket, except maybe at an edge which doesn't really mean anything unless its leaking coolant there as well

So could I get away with just changing the timing chain cover gasket? If I change the timing chain cover gasket will it affects the oil pan gasket?

yep, that's what the bottom of the timing cover seals to.

I dont know what to do with this so Im just gonna leave it here...

You... you guys will take care of this right?

well that is going to suck having to change to oil pan gasket as well. Now I am going to have to take the engine out.

You dont need to do the oil pan gasket. The timing cover should come with the end peice of the oil pan gasket. You cut the old gasket even with the block and glue in the new peice.

so I looked up the the timing chain cover gasket and it does not come with a piece for the oil pan. It says you have to buy the whole oil pan gasket. So with that being said. Do I need replace the whole oil pan gasket?

 

[gungfudan]

I watched some videos and no one ever changed the oil pan gasket when changing the timing cover gasket guess that is what I am doing.

Just sillycone the bastard. I've always seen those partial gasket peices though...

Not a 3.0 but just showing what I mean...

Yeah I knew what you were talking about. I have seen them before now that I see this picture. Unfortunately they don’t make the kit that comes with that. Like I said everything I saw from YouTube videos people never touched it.

This is what rockauto and all the other parts stores have. And it says to be used with.... and gives the part number of the whole oil pan gasket.

So the way it works is that the oil pan sticks out a bit from the main block. That bit that sticks out mates up with the timing cover and provides some sealing along the bottom for it. In fact, you have to rtv the corners where the two meet. If you have the old style oil pan gasket, I could see where you just put a fresh gasket part in, rtv/silicone in position and be done with it. In my case I am a masochist so I dropped the pan and replaced the oil pan gasket with the new, upgraded gasket. You can drop the pan without removing the engine block and replace the gasket but it is a giant PITA. dropping the pan involves loosing the motor mounts, removing the starter, removing the accessories chunks, cooling fan, etc, etc. Up to you how you want to go about fixing it.
