Chocolate Milky Color. Bad head gasket? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

RandomVelox · 03-21-2012, 11:19 AM

I received my SR20DET engine two days ago from Zerolift. When I removed the spark plug wires, there was a little bit of oil sitting at the bottom of 2 of the 4 spark plugs. I remove the valve cover and everything seems perfectly fine. Very clean. The cams look perfectly fine and as well as the timing chain and valves. So I remove the whole turbo manifold assembly and as I tilt it to the side, chocolate milky liquid comes pouring out the turbo oil lines. My first thought was maybe a bad headgasket? But I'm not too sure. I take out the oil stick and the end was very clean and had a little dark oil on the tip. No chocolate milky color. I just wanted someone's input before I start tearing the block down. Do I have a bad headgasket ? Thanks and very much appreciated.

Return it? Hmm. Well I honestly don't think that just because of a head gasket I'm going to return a perfectly fine looking block. I just wanted to know if either it's something in the block that's causing this or just the turbo assembly. Thanks for a reply though!

silnv · 03-21-2012, 11:44 AM

Have you drained the oil out of the block yet? Or was there any in it?

RandomVelox · 03-21-2012, 11:45 AM

There wasn't any oil. Very little. Almost nothing.

silnv · 03-21-2012, 11:49 AM

How about the oil filter? Has it been removed. Just trying to get a idea of the oil that was in the block before it was drained.

RandomVelox · 03-21-2012, 11:51 AM

Hmm good idea. I haven't removed the oil filter yet. But I will to see how it looks. Thanks!

silnv · 03-21-2012, 11:55 AM

Hopefully that looks good, and you are in the clear. These used engines are just like a grab bag, might get a good one might not.

RandomVelox · 03-21-2012, 11:57 AM

Hahaha getting me nervous for the moment of truth. Well I'll look at it when I get home. Thanks for the help! Appreciate it. I'll post once I see what it looks like.

Vadim's13 · 03-21-2012, 01:19 PM

Could be head gasket, if u wont find anything apse and u gonna desire to pull he head off look for dark spots around water jacket... may be take a pic and post it up here

whiterps13 · 03-21-2012, 01:27 PM

More ovaltine please.

RandomVelox · 03-21-2012, 01:59 PM

Well I took the oil filter off and I'm relieved. It was just liquid sitting in the turbo so the block is good. Gonna flush it out and it'll be ready. ^^ thanks again.

S-Nation S13 · 03-21-2012, 02:04 PM

If you suspect bad hg better check to see if the block and head got wrapped..just because it doesn't look bad doesn't mean it's not..

RandomVelox · 03-21-2012, 02:05 PM

Hey I completely agree so I decided to still do it

jr_ss · 03-21-2012, 03:50 PM

I'd put a new factory headgasket and ARP studs in it for future upgrading. Much easier with it out of the car...

R@ddy · 03-21-2012, 05:59 PM

zerolift has awesome rep. they know what they're doing so im sure it was oil and water that just append to be sitting together. if the oil in the filter is good, so will the engine. if you're going for more power, throw in a metal head gasket (COSWORTH) and arps's

+1 for the metal head gasket if you are gonna pull the motor apart to replace it you might as well upgrade

RandomVelox · 04-12-2012, 02:47 PM

Well it's been over 3 weeks and the engine has not been dropped. Turns out the flywheel that it came with was the DE instead of the DE-T so my Stage 3 Spec did not fit. The O2 housing is broken on one end and didn't even come with an O2 sensor. The wastegate is also bent. I've contacted Zerolift so now I'm waiting on the parts. Hopefully they'll arrive soon.

blessedhellrider · 04-12-2012, 03:13 PM

oil and water makes chocolate milk .well you can always take that brown milk to a lab to determine if it is in fact water/chocolate milk. or could just be a solvent used to flush for shipping purposes.
or just maybe mud ...oohhhh .whAT WHat what wait spark plug "wires"?

RandomVelox · 04-12-2012, 05:49 PM

Yes, wires. So I replaced o-rings on the valve cover as well.

*fliprayzin240sx* · 04-12-2012, 06:19 PM

Japanese loves using straight water instead of coolant. Could be rust build up from doing so.

bookoo · 04-12-2012, 06:20 PM

Zero lift has a bunch of fucked up shit.

RandomVelox · 04-12-2012, 10:24 PM

Yeah, I pretty much figured that out about the turbo manifold. All I'm waiting is on the parts now.

*fliprayzin240sx* · 04-12-2012, 10:53 PM

Wait...I could have sworn the DE and DET flywheels are the same. I could have sworn the clutches are interchangeable between the 2.

Ya they should be the same diameter to reach the starter?... same size blocks same location starter aye. perhaps you have the wrong clutch

I'm probably wrong about it being the DE then but I know it's not the correct clutch. Look at the 3 pin pattern and compare it to a SR20DET flywheel. It's different. And my clutch is SN333 so I'm sure that's the correct clutch.

They are the same. I wonder what the OP was talking about. Iirc i think i swapped by clutches around on a DE and DET. It doesnt make sense for nissan to make sense for 2 different flywheels anyways.

The chocolate milk stuff is water with mineral deposits. The turbo cooks it up and if water sits in there it get nasty.

I mean don't get me wrong that flywheel fits perfectly but this is what I mean about the pin pattern. Here's an SR20DET flywheel I found online. Notice on the flywheel I received the pins are more centered?
