I was thinking earlier, wonder if there is anyway of making a car engine not blow a headgasket? So say not driving fast from cold, regular oil changes and coolant changes......Or would this not be the case? My mechanical knowledge is far from good by the way
Yeah, a big boost Cossie uses a metal or similar gasket, in the 90s people had copper rings added and many like my 2.2 Stroker have 10 long studs machines in to the block to help stop the head lifting off at high boost.
the Duratec’ is quite a modern engine and was used in twin turbo form in the noble, have a look
at Guy Martins 170mph plus Transit that he raced, that had a boosted Duartec V6.

Thanks mate. So some engines needed long studs to save the head from lifting off at high boost, s#it me, so serious amounts of power then!
I will look for that transit now mate. My engine has done 74k with full history. I change the oil and filter with Fords OE filter and oil every 3-4k. Bit over the top, but I like to take extra care of my cars.
What are the head gaskets like on the V6 Duratec engines? I remember the Rover K-Series engines being terrible for blowing HG's.
Please PM me a price and some pics of your oil induction kit mate
Why are you so worried about the head gaskets blowing? You are very unlikely to have any problems with your standard Mondeo engine. Drive it ,clean it,enjoy it and dont worry about the head gaskets.

It was more of a thought than a worry mate. Popped into my mind earlier as in what could prevent any head gasket blowing? Lets say a car has its oil changed every 1,000 miles and is driven with great care.....Would this car have less of a chance of a head gasket failure to say a car that has its oil changed every 20k and is driven very hard daily, or does it not work like that?

If you have a car which has long service intervals this is what the engine has been designed for and would not have any issues with the head gasket. If you drive the car hard or with great care again should not make any difference.Turbocharged cars running very high boost have to have extra safeguards to protect the head gasket ie long studs, multi-layered metal head gaskets etc but on a standard non-turbo engine there is no need to do anything extra and oil changes again have no direct link to failure.
When they first came out the (3dr) Cosworth had issues with the head gasket. This was especially a problem in Germany on the unrestricted autobahn. If the driver accelerated hard the cylinder head expanded due to the heat and when the driver lifted off the head contracted again which moved the head gasket. In the end it was solved with a metal Omega ring in the gasket. But in my opinion this shows that quicker heating of the head than the block can give problems with the head gasket. IMO driving it gently when cold will also make the chance of a head gasket failure less likely. On boosted cars the head gasket will have a harder life anyway due to the higher cylinder pressures (more power out of the same cylinder volume than an atmosferic engine).
You can O-ring the block they also do this with drag cars. A grove is made in the cylinder block and filled with a special copper wire. The copper presses into the headgasket around the cylinders. It gives a stronger and tighter seal around the cylinders. It prevents the gasket from moving and creating leaks. had my car done also. You can also do this yourself, there are some diy sets though i should let a machinist do this. Tapping in the copper wire is a pain to do.

I think you need to use the best head gasket for the application. It is relatively unheard of for a modern engine to fail.
big turbo boost needs proper gaskets
lol not not really just look at the focus rs mk3 , normally multilayer metal head gaskets are the best , if you are running big boost then coopers rings etc
no you cannot really do anything , normally its down to a problem somewhere else like wrong coolant ratio , to much boost , head and block not faced properly , running engine with no water , dodgy stat not opening and boiling water in the block for to long etc etc.

My 2wd Saff had a brand new 200 block which was wire rung, low comp, pocketed Mahle pistons and fitted with a group A head gasket. It has not failed despite doing over 50,000 miles with 2bar boost!! Many miles of hard driving but always maintained and looked after.
Can you protect a head-gasket from blowing?
