I repeat the following post which I made in 164 Forum.

My car is a 164 4-cylinder Twin Spark. It is in a middle of an engine overhaul. A few of the cylinder head studs are pitted due to corrosion. The workshop tried to take out the studs but it was not possible. So it was decided to get another engine block.

Bought a used engine block from Europe. The second main bearing housing was previously repaired. I was not informed by the seller during the correspondence. It is also missing a slot for the main bearing. Is the repair seen in the photo acceptable? Is it good enough to withstand the load and vibration of the engine?

The locating lug is only for ease of installation. Thinking of grinding off the locating lug on the main bearing in order for it to fit into the housing

Thank you for your attention.

No oil holes in second and fourth housing. Oil fed through the crankshaft.

wich version? 8v or 16v?

164 Twin Spark only 8V. No 16V.

I would like to see the original block's pitted head studs as I would probably use that block instead of this repaired one.

Why?, because for a block to need that sort of repair it has experienced something very nasty and extreme. Why take the risk, considering they haven't even fixed it properly as missing the bearing shell notch. BTW: If you do use this repaired block, don't grind the bearing shells to remove the locating lug, but simply use a dremel and create the locating notch in the block.

Also on second look at that repaired block the repair is not even square with the block => I think it is either needs to be trashed or repaired properly. If you can return for a refund, that is what I would do

On 4 of the studs, at the bottom before it goes into the block it is no longer round. Small pieces of it have come off.

The photo does not show it but the repair insert sits correctly on the housing. Camera optics/distortion. For example, the highlighted part does not look straight in the photo but it is actually straight.
