I think the pistons were trying to escape from the engine!!11~ More seriously though I don't know...

i wasn't concentrating at head gasket school, so i dunno either

 

[CMF_darkfibre]

Looks like overboost or severe pre ignition to me,
Was it turboed?

 

[CMF_tris]

running aviation fuel??? hah engine beginning to melt??

 

[CMF_turbo march-rolling shell]

was the actual gasket still sealing? as the part that is mainly ****ed up on the gasket is just where water would flow...

edit: yeh.. that does look pretty ****ed up eh. lol. too much heat.. running lean as i'd say.

 

[CMF_evade]

yes..too much heat indeed..

like my old one!

 

[CMF_tris]

wow yeah now that is rooted.... actualy sorry to kijack your thread but does anyone know how to clean out corrosion/white **** from inside the collant holes in your head and bottom half of the engine?? i need to clean out my 5me head before i put it on. would a radiator flush work??

 

[CMF_jaxx]

turbo charged yi.

you can make your own gasket look like mine, heres what to do:

rebuild you engine with the wrong bolts, or for those bolts that don't fit you can just cross thread them. failing that, just dont bother using them at all!

going for +200bhp, standard head gasket will be fine. i only bought the custom decomp plate for show!!

then put a turbo on there with dogey pipe work mixed with dog ugly **** welding.

then put the car on a dyno, try and map it with the intercooler 80% covered up and waaaala. the charge temperatures will be so high it will cause detonation. dont stop just keep going! then when its off the dyno dont let it cool down, just boost it silly round the block and you will here a gun shot sound, followed by smoke. enough smoke for 'stars in your eyes' lol

there you go

 

[CMF_jaxx]

this is what it made on standard head gasket. it would have probably done quite a bit more if other fundamental things were done properly

 

[CMF_darkfibre]

Woo Hoo
I was right

"Looks like overboost or severe pre ignition to me,<BR>Was it turboed?

 

[CMF_tris]

did you want to destroy it??? haha sounds like it...

 

[CMF_turbo march-rolling shell]

lol.. you'd think if it was detonating hardcore like that they would of backed of

 

[CMF_jaxx]

tell me about it. and believe me i didnt want this. its getting rebuilt properly this time but as we go deeper in the engine these problems are becoming more apparant. if people are interested in the build i will make another thread....looks like this at the moment...

 

[CMF_micra_pete]

jaxx, who mapped the car? if you don't mind me asking

 

[CMF_tris]

got vids of the dyno run.. haha i wana see an engine explode

 

[CMF_jaxx]

wish i did be honest lol. gunna leave micra pete question for now, sorry dude, long story.

bit off topic... but did you choose to paint your car that colour or is it a stock nissan colour?

 

[CMF_Tony]

Isn't that the gold colour available in Australia but like all Nissans the paint is flat under the bonnet not gloss.

 

[CMF_micra_pete]

okay Jaxx.

Any reason, it sounds like they didn't do the best job! north or south? make with the clues

 

[CMF_jaxx]

yi its stock colour, dont know the spelling but it's pronounced u-gan gold. micra-pete it was up north and thats all you getting lol. you down south? what setup you need mapping?

 

[CMF_fred]

man, u gotta be careful with turbo stuff, hay. (glad I went water intercooled...and 5psi.....and water injection(soon) and exhaust temp gauge.... and a/f ratio meter..... and drive like a girl (no offence to the ladies out there)

 

[CMF_jaxx]

i know what you saying, but the engine is bullet proof. arias forged pistons and crower rods to name a few. hopefully this time it won't go pop. gunna be running a little more than 5psi though lol

 

[CMF_micra_pete]

haha, thanks Jaxx

I'd do my own mapping, but just wondered where to avoid for engine work?

erm, wasn't north east was it? lol.

trying to narrow it down without you saying!!
