To improve cooling and detonation resistance,
the cylinder head has a cooling passage placed between each pair of exhaust valves.
The proven concept of the exhaust manifold integrated into
the cylinder head has been retained.
Charge air is cooled through a high - capacity air - to - air intercooler, while
the cylinder head has a two - piece water jacket to lower exhaust gas and combustion chamber temperatures.
The cylinder head has a two - piece water jacket, lowering exhaust gas temperature and effectively lowering the combustion chamber temperature, while each piston individually features a cooling channel to provide increased oil flow.
Apart from the mounting positions of the fuel injectors,
the cylinder head has conventional port and combustion chamber designs, although both are optimized for direct injection and high boost pressures.
In contrast to the previous engine,
the cylinder head has a «rotated valve star» layout; each of the two camshafts actuates one intake valve and one exhaust valve per cylinder.
Cylinder head has two camshafts and four valves per cylinder.
This cylinder head has improved intake and exhaust ports, larger valves (intake 36 mm, exhaust 31 mm), aggressive camshafts, and stiff valve springs.

When you worked on the Ford Essex V6's cylinder heads you'd often break into the water passages.
Cylinder head had two camshafts with 4 valves per cylinder.
The cylinder head have been developed anew.
The cylinder heads have larger intake valves and an improved intake port design.
The cylinder heads have the exhaust side on the inside and the intake side on the outside.
The cylinder heads have altered intake and exhaust ports to improve flow, as well as smaller pent - roof combustion chambers that increase the compression ratio from 10.1:1 to 10.5:1.
The factory
cylinder heads have also been ported and camshaft has been upgraded.
To save weight and reduce parts count,
the cylinder heads have uniquely integrated exhaust - port castings that provide optimal positioning of the close - coupled catalytic converters - one on each cylinder bank.
Parts of
the cylinder head would remain metal out of necessity, of course; Ford's patent application describes an «internal metal structure» made of cast iron, which could include the upper combustion chambers, combustion chamber inserts, fire deck, engine coolant ports, and oil drain ports.
Innovative breathing The high - flow
cylinder heads have a lightweight valve train, contributing to the IS F V8's high - rpm capability.
Key elements include: - Aluminium block with built - in reinforcements High - flow intake ports and high - speed, high - lift valvetrain to enable high engine speed and power Compact intake fuel surge tank to increase engine response Oil scavenge pump, to ensure stable oil supply in even in high G - force bends Liquid - cooled oil cooler for more efficient temperature control during high - load driving Weight - saving hollow camshafts, which carry oil to
the cylinder heads D - 4S (Direct - injection 4 - stroke gasoline engine Superior version), combining direct and port injection Electrically - driven VVT - iE on intake, with mechanical inlet and hydraulic outlet valves
Its cylinder heads have been substantially reworked for high - rpm duty, including nerd - porn finger followers that incorporate hydraulic valve - lash adjustment.

having won five straight matches to close out this season.
Some manufacturers
have increased engine capacity by boring out the
cylinders this in some cases
has left very little metal between the water jacket and the
cylinder head if you don't run glycol with an alloy motor this can corrode allowing water into the

Pull all the spark plugs and remove the

While there is a remote possibility to salvage the
cylinder head by
having it skimmed by a professional machinist, in all probability it will need to be replaced.
The TLX GT benefits from an Acura - developed aero kit,
has a race - oriented all - wheel - drive system and six - speed sequential racing gearbox, and a twin - turbo 3.5 - liter
V - 6 that retains the stock
cylinder head and block, direct - injection, crankshaft, and throttle body, and adds racing connecting rods, pistons, camshafts, and dry sump lubrication.
Either the connecting rod failed and allowed the piston to travel to the top of the
cylinder, or you
've got some kind of foreign object (like a valve
head) inside the
cylinder.
At least Porsche
had a suitable engine: the 2.6 - litre twin turbo flat six, with air - cooled barrels and water - cooled
cylinder heads, originally developed for the unused Indycar project and used in the last of the 936s the year before.
Some companies still practice this however most
have switched to aluminium
cylinder heads with pressed interference fit hardened armored exhaust valve seats.
While it retains the bore spacing and displacement of the 3.5 - liter EcoBoost that
has been in production for several years, it
has a new crankshaft and
cylinder heads, and both direct injection and port injection.
I don't
have a «qualified» answer for you, but if there's nothing sticking down into the
cylinder space on the
head (ie: valves), you should be golden.
I think a compression / leak - down test on all
cylinders would be useful to help you identify if a bad
head gasket is to blame here.
I
Would NEVER attempt to drive a car that is overheating (you may cause a lot more damage e.g. seize the engine or crack the
cylinder head).
You guys really
have no idea what yous are talking about get the
head off and you will find the
head of a valve gouged into the

If the socket and bar sound like they are still loose in the
