I've dry decked my head, and believe all the others that run the bk450 have also done the same. I'm not to sure if its possible to run a bk450 it hour dry decking, or at least blocking off a few of the water galleries.

hmm, if you've killed the sc one definately check the afr's and ignition timing. not heard of one fail and they look substancial. On 7th Oct, 2010 5haneJ said:

Specialist components don't do a cometic gasket, but I believe MED do.

Sorry, yeah. Its not cometic, that was what i had fitted before the head conversion. SC ones are Ferriday Engineering bi-metallic ones.

When I said I experienced a failure of one of those gaskets, it certainly never looked like that.

When I said I experienced a failure of one of those gaskets, it certainly never looked like that. At first glance I am thinking of two possible issues. Firstly, poor cylinder head clamping and second, Detonation. What sort of ignition advance do you have when on boost? What head studs are you using and what do you torque them too? Do you use the correct torquing sequence? Interesting one about the head studs / clamping theory. The head has been off and on about 10+ times in the last few months.You think the studs could have stretched with the repeated tightening and undoing? Just using the standard head studs, following the SC guide - 30ftlbs in sequence, wait 30mins then 45 ftlbs i think it is. working from the centre out. I've not played with a main spark advance table at all. Think its 24 degs at full throttle higher up the rev range - not sure if this is altered much by other parameters to calculate final. |

Did you drive over that repeatedly before taking a picture?

Never annealed it when new or refitting (it was also 5+ years old i think). First i've heard of the technique but it does sound worthwhile when using a copper gasket!

Wow. I've had a few head gaskets go, but that is on a whole new level.
In the 13's at last!.. Just |

*running lean - dont think so, as it was setup on RR and i havent touched the map. Havent had a chance to validate with my own lamda as i dont have a gauge and the logging isnt working Alarm bells ringing here! Get a wideband AFR gauge on it ASAP and confirm what mixture the engine is burning at any given point. The picture of your gasket above makes it look like the head has been getting hotter than the sun... This could be a number of things, including the AFRs being way off, but I would suggest that you get it dry decked to help with any potential coolant/cooling issues, as you have mentioned. |

I'm pretty confident it isnt AFR issues, but these things are never 100%..... Its fine at actuator boost, and the fueling is just impacted by a pressure multiplier as far as i understand it. Its going back to the RR for checking once its all built back up anyway.

Your list looks about right. There's some photos on my build thread showing what you need to do and where everything goes. I'm assuming as its a k1200 so will have external oil feed already. |

I've seen your thread, the build looks amazing! I see you have welded an adapter where i think there is a core plug currently? Is this the flow or the return. If its the flow, where does the return go? |

Also, ive read on here that there seems to be a bit of debate about whether to run a thermostat or not. I dont, and didnt run one for the last 2-3 years with complete reliability. NOt sure if this could be a contributing factor in the turbo saga or not... |

Does your rolling road use a massive big fan at the front of the car which is keeping the engine temps right down, so your tune doesn't represent the real world environment it's used in? On 11th Feb, 2015 robert said:

I ran mine with a copper gasket for 2 years without any overheating problems, and i only had small 4/5mm drillings in the block to head. What temperature did the engine run at?

The water comes out the welded in adaptor on the end of the head and in the front core plug hole on the end of the block just below. You need to make/buy an adaptor to go on the block end and a 32mm 180 degree hose bend to connect them up. It's pretty simple stuff. |

I would go with the dry deck, just means a bit of extra work but could solve a lot of problems. I don't know much about the AFR yet. |
