Hi nkurciev.

Can I draw your attention to a paragraph on top buzz titled ......."How do I Know if my head is pourous" .......which discuses oil contamination.

Regarding heads made by Kolben Schmidt the chart indicates that these heads are prone to becoming pourous but will not always happen.

The water channels and the oil channels are close together and the aluminium between the oil and water corroed hence the mixing of the two fluids.

Cosworth manufactured  heads......marked "CossCast" on the head are made of a better alloy casting and higher quality did not suffer this problem.

If you have oil and water contamination it Can be fixed......you have to consider Price of repair to price of a new head.

If you decide on the latter then it would be prudent to buy a CossCast head for greater peace of mind.

Hi

Not sure of what your reply mean sorry......can you rephrase your question a different way.  If you are asking are CossCast heads only fitted to Calibra turbo models then I am not sure if this is the case.

The cheaper option of having your engines head repaired is good because they insert pipes into the oil and water ways.....not sure of the metal used but could be stronger than the heads alloy casting.

Perhaps a Cc member could help here.

Hi

Going for a CossCast cylinder head is by far the best option.....they have been proved to be a better quality.....make sure if you do buy one you identify the "CossCast" name stamped on the side of head.
