oil in my water

 

Congrats you blew a headgasket! Time to pull the head.

 

how the f*** did you blow the head gasket?

 

he was waiting for vtec to kick in yO!!!!

 

jesus it really is the world's longest motor swap

 

i'm guessing its the head i bought used from pierre's Z last year is cracked. or maybe the block is. who ****ing knows all i know is that i am getting no mercy at all time for a rebuild even before i finish **** every****ing thing

 

check and make sure its not warped

 

okay 100 bucks for getting ****ed is understandable but i paid 250 and i paid a man

 

is it a p90?

if its warped it can be milled flat again

 

yeah how'd u know its p90 and how u know its warped and why didnt i know before i put it on and why now god

 

Wow, bad luck! I guess we're doin the same job.

 

Why not make sure all the head bolts are TQed down right first?

 

its a turbo motor

its just a guess, but normally when a HG goes for no apparent reason it tends to be a warped head

its not always obvious if your not looking for it

hes smiting you for touching yourself at night

 

Doesnt help you had that Z dieseling before either...

 

you think maybe that huge backfire i had helped screw it too? yeah i might as well make sure they're all torqued down, wouldn't that + gasket take care of any 1/1000th inch of warp?

 

That little of a warp? Ya

 

you are using a decent torque wrench right?

 

any head i buy i take to the machine shop. usually check it out for free. probably warped before you put it on. a backfire wont really warp a head. over heating does or usinge the wrong torque pattern or letting it sit to long on a non flat surface or not unbolting it in the right pattern or valves hitting pistons can do it.

 

Buahhahhhaha!!!!

 

So as you know I had my engine running until it patrick swayzed and got oil in the water, which is a mystery. Its all torn down now and this is what I'm looking at.






The head has passages where water COULD be flowing but the block doesn't even have passages for it to go! Nevermind the fact that the gasket blocks it off...

So what else could have gone wrong? The pistons are looking clean though and so is everything else. What else should I be looking for

 

Did it overheat? (I can't remember... and you started a new thread instead of continuing your other).

The ports on the headgasket depend on which head / block combination you order it for. I've done more than a handful of L28 head jobs and found that some are made diff than others. Hell, my MLS headgasket from MSA didn't have the right ports, so I drilled them out after another head job. I haven't raced it since then to see how hot it will get under a heavy load, but running on the freeway in 100*+ is cooler than it used to be.

See my thread on that: https://www.zdriver.com/forums/showt...+gasket&page=2

 

Why is this in OT?

Anyways You can get oil in your water though the timing chain cover gasket. not just the head

 

Merged w/ previous thread & moved to correct location in S30 motor swap section.

 

What brand headgasket are you using? In my experience, the Fel-Pro gaskets do not match perfectly with the L series motors, and I kept getting oil and water mix. I eventually went and sourced a Beck/Arnley gasket from Napa, and I haven't had that problem since.

 

I stand by fel pro gaskets been using them since 1985 and have many Z-friends and techs who swear by fel-pro gaskets. In my opinion the cyl-head is the problem until you do a professional pressure test and also for warpage....o/k.
