Hi there,

Hello good afternoon, I tell you a little the problem that I have, it turns out that I have a renault express 1.9d, and for the expansion bottle, I create a foam, like that of a beer, this foam is white. In the expansion bottle, no oil remains are seen, the antifreeze is clean, when I rested, in addition the sleeves are put like blackberries, come on that we could mount me. It smells like a cooking together, but the question is 1 year ago that I was done. The refrying circuit is well purged, the van has enough kilometers, but the care is well.

Thanks, beforehand.

For what you comment and you say it looks like it is a buttonal joint before it disassembled it would put pressure on the circuit to check if there is any fissure in the joint or butt.

It is a butt or fissure joint in the cylinder head, the F8Q and F8M engine did not come out very hard in that sense. Since you get the cylinder head and check it under pressure, take out the radiator and take it to clean it, it would not be to be the culprit that the engine is heated more than the account.

All the best.
