I had one of these heads crack cross ways in the center between the two exhaust valves right under the rocker shaft where the casting bulges up. Pull the valve cover and take a look while cold and also while running the engine. If the crack is there and is not too long, a plate with a gasket could be bolted down over it for a seal, without removing the head.
help wanted, internal water leak SOLVED

Hi Guys,
Thanks for the tips.
But the head and block mating surfaces have been surfaced.
Basically the engine has been to a machine shop, where all the internals have been replaced.
They tested the head, its not leaking.
We concluded there is a crack in the lower block, not in the head.
They can't find the crack, so can't I.
But that is a small weeping leak I was planning on fixing with Bars and not the amount that I've got now after I installed the head, thicker gasket and RTV.

Hi guys,
Just to let you all know what happened with my water leak:
I had a crack in the no 5 (i think) valve lifter boring.
The differences in water leakage were probalbly caused by the location of the valve lifter, in the up position water could flow better through because of the shoulder in the valve lifter, in the downward position it was blocking the water flow somewhat.
It cost me 3 head gaskets before we finally got it, I was about to try the bars leak when I noticed bent pusrods. That sent all alarm bells ringing and I pulled the head, to find some of the valves binded up due to rust.
I then pulled the engine threw it in the back of the car and drove to the machine shop. They took the engine apart and found the crack.
I had to replace the lower block, fortunately I had 3 lying around.
So I ended up paying for a second honed block, but it sure as h*ll ain't leaking.
The reason they didn't notice the crack first time around because I cleaned the block before I took it to the machine shop.
So, if I ever have to send an engine to a machine shop I will not clean it to save some $$ on the cleaning fee. :idea:

Glad you finally found the problem!
That is so appropriate. An archeologist likes old cars.
Good deal that you found the leak. So when you say 'lower block' you mean the basic block, as opposed to the head, fx Right? Whew. That's a way to fix a leak.
So when you go to change out the next 'lower block', you might as well get a 200 to replace the 170. The exterior is all the same size and with that 3.50, you could really jump off at the light.
BTW, what's your area of specialty? Frisian terps?

Hey Ludwig,
Yeah I meant the casting, all the internals were used in the new block, with the exception of the cranckshaft and the camshaft. The ones from the donor block were far better then my originals. So something good came of it after all.
A 200 is not something that is lying arond at the local scrappers in abundance.
Remember, this is europe home of the 4 cylinder car.
Best chance i've got for a 200 is from a mustang, and then, what condition is it in? I could have bought a "recond" 200 but after some questioning, it turned out to have a recond head, but the lower block was still original, so I decided against it. Also I have the relatively weak 2.77 tranny and on some forums I was advised against installing anything bigger than the 170, or else risk losing the tranny.
Yup older car, older woman , they don't build them like they used to
I graduated as an physical geographer, with a specialisation in pollen analysis, landscape- and climatic reconstruction.
In dutch arceology most of the time you're reconstructing buried landscapes to try and interpret if, how and when that landscape was suitable for habitation. Basically what I had learnt to do. It is great fun.
Frysian terps are a good example of the often difficult conditions the dutch people had to cope with. You're living on a piece of land that gives a good yield in terms of meat and other resources, but it floods twice a day and in winter you get exeptionally high floods, so you buld yourself a nice mound with a house on top where you keep your cattle safe and have a well that wont go bad due to high salinity. AND you stand a goot chance of kicking some roman butt, or whatever ruler who wants to submit your community. Sorted!
But in the better part of seabound netherlands there are terps, either at the surface or overgrown by peat.
