A friend of mine had mentioned using a cleaner meant for aircraft to use on aluminum parts. I didn't catch the name, but he said he's using it to avoid the aluminum + oven cleaner issues.

Thanks for the warning. I am using stuff from the Dollar Store and have not had any problems. I used it on my other "P" car, the one with 2 names and it was fine, but I will sill pay attention. I only leave it on long enough for the grease to show signs of running, a couple min. then wash with carb cleaner or lacquer thinner.

Kevin,

I see Aircraft Spruce who is near me has a Velocity Visions aluminum cleaner and brightener, and I might give it a try.

The oil, grease is so thick I am starting with a plastic putty knife to start with.

I am trying to find something to brighten the aluminum, I don't want to paint it.

Look for cracks in the timing cover. Top and bottom.

The hose in/out. ?. I used aluminum spool gun.and built it up.

And welded cracks.

The water pump part. That gets pitted. I heard marine tex is used.. Epoxy..

To fill pitts.

Riki,

Thanks for the suggestions. Did you have any issues with the MIG welding? What I was going to do is inset a 1 5/8" OD stainless tube in the ID of the water outlet, fabricate a ring of aluminum to slide over it and weld/epoxy it to the remaining housing.

On the water pump area, I was thinking of either filling or cutting out a circle and welding a new circle in. That is kind of why I was asking abut the MIG experience.

Not really. Heated with a torch . I did media blast the cover to get it clean.

With the torch put black on the area. Then heated till it was gone. Then started building.

I was also thinking of putting a piece inside. But then a guy who teaches body shop said it can be welded.

Then I used a file and cutter in a drill to clean it up.

Have to look for pictures..might be on my blog.


Edit.

Between welds used a stainless brush and alcohol. And did not touch it ..after that. No hands.

Alcohol was in a squirt bottle.

Riki,

Thanks for the info. How thick do you think the aluminum is behind the pump impeller? I ordered a 4" x 1/4" aluminum circle and was thinking of cutting out the back and welding that piece in.

Riki,

I noticed some structure that enclosed the impeller. You don't happen to have any pictures of what it looks like with the pump out?

Thanks

Bill

Riki,

Ok, I got my 4" aluminum disc, MIG with Argon and 5356 .035" aluminum MIG wire and an .040" tip. The grade and tip size help negate the need for a spool gun. (sort of)

I think I will preheat on a small grill and have a go at it.

Wish me luck.
