Head pressure testing

Featured Replies

Does any one recommend a good garage to pressure test my head local to medway/kent as possible?

Whether petrol or diesel, most garages would have the necessary test equipment and understanding the results..

Sorry I didn't make it clear I want to take my head off and get it checked for flat and any cracks

Remove head and give it a good (careful/ gentle) clean first, by removing any remains of gasket etc.

Using a steel rule and thinnest feeler gauge try to push feeler gauge feeler between steel rule and cylinder head surface head..

Maximum thickness would be no more than 3thousand of an inch (don't know much about millimetres), sorry.

Head gasket can accept up to 3 thou, anything over that, it's a head skim job.

You could otherwise just take head to machine shop and ask to skim minimum off head..and look for cracks.

Fingers crossed no cracks found.

 

Oh! whats prompted you to want to do this check?

I've had a sniff test carried out on the car and it confirmed my head gasket has gone, I am going to take the head off and replace all seals ect. I just don't want to go through all the hassle of having it off replacing everything and find out the head is cracked or the gasket goes again :)

Suggest don't replace anything yet, get it skimmed first as really only true way to see any crack's, on head surface when it's nice and clean.

Apart from spotting an obvious crack in the side of the head, or elsewhere for that matter, do suggest get it skimmed.

There's a fine line between getting it skimmed isn't there? You can quite easily muck the timing up can you not?

Your talking about less than a pencil line being removed/ skimmed (if head is not warped)..

With the Fabia VRS then you would have already removed the timing belt etc, and would re-set the timing on re-assembly.

Timing slightly but compression and valve interference is more Likley.

Check the difference between the two hole head gasket and then the three hole gasket, whatever the difference is that's the maximum that can be skimmed.

Glow plugs, injectors and valves need to be removed for getting the head skimmed.
