i spoke to Ferriday engineering earlier today about a decomp plate, they told me only to use 1 head gasket, betweenthe head and the plate, surely you would use one either side??? i was seriously considering going down the decomp plate route but, the more i think about it the more im deciding against it, 2 gaskets and a plate = 3 times as likely to blow anyone got any views on this? |

ha! wondered how long it would be before someone said that!ive suddenly realised there is no such thing as a budget turbo conversion, especially a 16 valver!! one thing i want to know is how the feck are people getting away with 300 brake and more through a standard engine... |

The reason you don't need two HG's with the Ferriday plate is they are made from copper, which is self sealing to a degree.I would imagine on the block side of the decomp plate a sealing compound is used, and then a HG is used between the decomp plate and cylinder head. I would go for the DP Engineering plate and use two decent head-gaskets. IMO, you will have a more durable, reliable and more long term solution. Having three different materials plus a sealing compound (to me) doesn't sound like a good idea given what the joint between a head and a block has to deal with. There's the heat, thermal expansion and compression, severe pressures etc. ________________________________________ Contact Details:rich@lynxpowerengineering.co.uk 07732 822546 |

Are the FAI gaskets that you get from motor factors considered to be good enough? they are MLS, through the garage we can get them for £26 each which sounds too cheap to me |

You just won't get the same sealing ability using a non-setting compound. For a succussful joint between a head and a block, you need what's called a mechanical seal. This is usually in the form of swaged areas on the gasket around the combustion chamber and fluid paths (this is the raised areas / lines you see on gaskets). The swaging creates areas of increased pressure between the head and the block, and they physically bite together. This is one reason alloy heads always need to be skimmed, as you often get minor indentations in the head where a mechanical seal has been formed. I've never used an FAI HG, but you get what you pay for, and there's a reason I use the HG's that we supply. ________________________________________ Contact Details:rich@lynxpowerengineering.co.uk 07732 822546 |
