Possibly a blown headgasket

[GettinPaper]

So a couple of weeks ago i blew a heater hose and overheated my car.. and it wouldn't start.. So I checked and i seemed to have water in the cylinders, After seeing that i decided to tear it down and check it out.. And this is the progress so far..
Let me know if everything looks fine!!
This is my first time doing a headgasket job! D

After i pulled the head off and was taking pictures i took this one and
noticed there was coolant in the turbo? Anyone know why?

The coolant in the turbo is probibly from when removing the head, some fell down in there..
Or some pushed through while you was cranking it over..

have fun with the hg. my car is in the exact same spot your is

Put some oil on those cylinder walls with a shop towel/rag, they will stop rusting that way.

the only part have had trouble with was lineing up the timing marks.

Do it right, do it once.

• Deck the block
• Mill the head
• Oil port mod the head before milling(search oil port mod)
• Hone the cylinders and or bore depending on condition and how badly overheated
• Replace Rod & Main bearings with your choice of brand
• Install ARP headstuds
• OEM MLS Headgasket

It might be out of your budget plans, but like I said, do it once so you don't have to open it up again.
You MUST resurface the head and block if your going to run a MLS HG as well.

Looks like my car 4 months ago.

Well i have arp headstuds and i have an MLS headgasket on it's way.

Yeah sorry, I glanced over those headstuds too quickly.
Anyway yeah, it's resurface time. Read up on how people who don't resurface they're block have a nightmare with them sealing.

Make sure your machine shop has a torque plate. Mine didn't but I said screw it, I needed the job done.

If you, or you know someone with a precision straight edge take a feeler gauge across the head and block assuming they're clean from most debris. Go top, center bottom from passenger to driver side. Then criss-cross. .002" is acceptable. (This however doesn't mean you shouldn't get it resurfaced). .004" or above it needs to be machined. The machine shop can only resurface a max of .008" however.
With that being said, a MLS headgasket needs I believe a 40Ra-50Ra surface roughness to adhere properly.

How bad did it overheat? Under load(cruising,boost,idle)?

I locked my keys in my car with my manual fan switch off a couple of weeks ago. Got up to 260*F and I sent a hammer through the window. Nothing was damaged cause it was idling. Meh, $55 window vs $2000 engine.
Before that, brother borrowed my car and overheated the out of it. My head was warped .009", scored the cam journals, wiped the walls on cylinder 3 and took out the rest on the headgasket. Gotta love that terrific oil cooler design that backs off.

Hopefully you're more fortunate then I was.

Hope you got your block decked.

And no, unfortunately this isn't a DIY procedure.

 

[GettinPaper]

Alright well i'm waiting for the headgasket.
I'll take some pictures of the head tomorrow.
and before i blew the heater hose i did a 3rd and 4th gear pull..
So under boost.. but i found that the heater hose was jimmy rigged..
someone cut it and spliced it because they didnt want to go all the way back
into the firewall to remove the hose..

+1 on getting the block decked / head milled!

Pictures and naked eye won't tell you anything. You need to do measurements, or pay the machine shop to do them for you.

Wow it's nice to know i'm not the only one. I Did the same thing on new years eve except I left the window cracked so I pulled it out and jammed my arm in to hit the unlock... so far so good.

 

[GettinPaper]

I forgot to mention there was previously a Mistu MLS headgasket on it..
But i'm going to get the head resurfaced.

hello, i seem to have a similar problem?
I have a 95 eclipse gst. the only major modification is the evo 3 16g gt but only running it at 6 psi. The other day i saw smoke coming out of my engine, so i opened the hood and saw oil coming out through a missing exhaust manifold bolt. I was already leaking air before where the exhaust manifold meets the engine, but now its dripping oil, and you can also see white smoke coming out through the exhaust.
At first I though I had broken the piston rings, but that would mean I would have really low compression and the car would run badly, but its running great.
What could it be, a bad headgasket?

Don't thread jack. Start a new thread. One of the exhaust studs goes into a oil galley. It needs to be coated with a teflon paste before you put the stud in.
Do a search on headgasket failures.
Do a compression test, then if you have low compression do a cylinder leak down test. This will get you started.

So i don't know if anyone order's their parts from JNZtuning.
But i ordered my Mitsu MLS head gasket on the 28th.
And it took till today for the billing information to be received.
It's been about 10 day's since i ordered it.
WTF

I tried to look at the surface finish on your head, but the plastic over the head I could not see...

I hope the head looks like this and whats not belt surfaced/sanded at the machine shop..
