Post Pushrod tubes
Help! Tried to search for this, but didnt find much about it...

It's regarding the pushrod tubes. I have got a head with a hole in one of them :cry:
It's not a big hole, so maybe there is a cheap solution to this, which also is proven to work?!

Somekind of wonder-goo, like JB Weld maybe?!

Or some thin sheet aluminium, shaped to wrap halfway around the tube, with Araldite and a couple of jubilee clips to hold everything together. ;)

That's still in place on an engine I put together about 15 years ago..

Or lacking the above perfect answers due to being in the middle of nowhere, a beer can snipped into a thin strip, exhaust paste smeared onto it, wrapped around the pipe where the hole is, two mini jubilee clips above and below and it was sill fine when I bumped into the guy years later at a world meeting in another part of europe. :lol:

But that was on one of the oil cooler supply pipes (high pressure circuit) :?

Thanks a lot guy's! Good thing it's that easy! Phew...
I cant find the Knead-it stuff on ebay or around here, but that JB-Weld I suggested, is the same stuff I think. I'll do as Viking suggested, and buy some stuff like that. I can get JB Weld from eBay.

Jubilee clips...actually had to google that, to see what it was. Haha, so common thing, and I have never heard the English word for them before!

I have some thin aluminum sheet. I'll do as you suggested Ken. I was thinking about a tube, slide it over and glue between, but it will be easier with a patch and jubilee clips.

I knew this was gonna work, but I was unsure if it could be regarded as a permanent repair. I think I've got the answer to that! If it works on the oil-cooler...! Thanks.
It's clearly important to stock beer in the car, while traveling :lol:



A bit OT here, but what's up with the A-modell heads?
During the last month I have taken apart 3 old engines I got last summer. Saved them from cars going to the scrapper. That's 6 heads, and of them only TWO heads had the spark plug threads intact. The rest was fitted with inserts-threads. And only one of those inserts was intact. Of the 6 heads one had a helicoil in the oil-pipe connection. And two heads had very corroded pushrod-tubes.

Typically, none of the heads was fault-free. I have chosen the only pair with good original sparkplug-threads to be fitted with new valves and refurbished valveseats. One head was almost perfect, only broken exhaustmanifold-bolts, I've fixed that. The other head had this tiny hole in the pushrod-tube. Which luckily can be fixed cheap and easy :)

On one head with a really badly corroded pushrod tube I tried removing the tube, just for fun. It did not work well, and I binned the head(Sparkplug threads molestet by a bad insert)
I also binned one head that was hit by the piston because of a busted big end bearing.(Also spark plug threads gone).

I hope this is not the normal state of used heads, or there will be hard to get good ones in the future :?

I'm going to get some from Australia. ''Knead-it'' for Raid Afrique.
If you or any one else would like some, let me know?
