Hi to all, i have just had a new zvh built all new gaskets rings pump ect ect... i have just found cream in my header tank and its only done 150 miles no wear near run in!

Any ideas!
maybe a dud head gasket!

Cheers

Danny

 

wht head gasket did u use??

 

Depending on how well everything was washed/degreased, i.e the block etc, there may be some settlement of oil and shite in the water jackets within the block.
When you obviously get it up an running again you will end up with a small amount of oil/degeaser in your cooling system.
If this were the case, there shouldnt be much creamy stuff in there and a good flush out of the cooling system should get shot of it (if it is that of course!)
If it aint bad, give it a good clean out with lots of clean water and try again. If it doesnt work, it could be the h/gskt

 

a ferodo head gasket was used and propa ZVH bolts!
what should they be torque'd up to? they are the allen key type bolts does that mean they are APR non strech ones? think i might double check they have been done up tight.

 

i know the head wasn't brand new so it was acid dipped.... would acid have the same effect as oil?

 

I would have said probably not....???

The torque setttings should be:

Stage 1 = 20ft/lb (27.12Nm)
Stage 2 = 40ft/lb (54.23Nm)
Stage 3 = 60ft/lb (81.35Nm)

In the same sequence as normal (middle to outside)

 

Do you mean the block was acid dipped as the head would disintergrate shurely.

 

now mate .i take it that its a 2ltr zvh ,if so you should of used a felpro 19 cvh head gasket mate.i think they are £40 from burton

 

not sure mate was told by the builder that they had the head in the acid dip for a couple of days!!!!

cheers top man, am i right in thinking the APR ones are the same but just miss out the 90degrees bit as there non strech

 

yeah its a 2l ZVH... i have an cosmetic multi layer reusealbe one for a cvh on my oter engine witch is only done about 1000miles whould that fit a 2L

 

The ZVH and the ARP ones both are NON STRETCH, it is only the standard ford stretch bolt items that have the 90 degree sequence. The ZVH ones torque up in the same pattern sequence, but only to the torque settings in each of the three stages.

As for the gasket, you cannot use this as the piston bore on a 2.0l is much bigger than the standard CVH which is 79.96mm

 

no fire ring is a different size.thats the ring which gos round the cylinder

 

ok thanks every one, you have all been very helpful. looks like i will be out there with a hose and torque wrench tomoz then

 

No Probs, Best of Luck!
