Nasty snot-substance buildup in intake! AAHH!!

[montegoman351]

You still probabably have a bad injetor, because the fuel spray isn't taking the oil residue with it. I'd agree with a leakdown test, and at least a cooling system pressure test. I usually pump the pressue tester to ~2psi over what the cap is rated at and one can usually spot a leak easily.

Good luck.

I would pull the lower intake manifold and check the intake gaskets. They are notorious for moving around when you set the intake down on em'. If you say that the milky stuff is emulating from the lifter valley then its likely an intake manifold gasket or maybe a head gasket.

 

[302RollinHard]

that is an oil water emulsion if i ever saw one. I would go ahead and do a leak down test to check HG's and then if they test good, R&R you lower/upper intake. Use some gasket tack to keep the intake to head gaskets from moving. Good luck, man.

I put back in the stock injectors-MAF. I'm going to go get new plugs and oil, change the thermostat/gasket and clean out the intake. Then put her back togeather crank up the fuel psi to 46 and see how she runs.

Then If she feels good and runs hard and dosn't lose coolant, I'll check the plugs, and see if the hydrolyzed oil is still being created.

If it is and it's losing colant I'll order up new HG's and intake gaskets...
Good tech in here.

 

[Mr. Rustypwnz]

Order new anyways, If I was u, I would strip it down and clean all that crap out, while its down, put on new hg's and lower intake gaskets, I had this happen to me right after I bought the 86 and it ended up being one of the hg's was bad, not loosing compression, just leaking coolant.

 

[vristang]

WTF kind of advice is that?


Its the advice he should be taking!!!!!!!!!!!!! Check all the vital signs if nothing shows to be wrong than you make a judgement by the data you collect....its common sense.

With all due respect, as you have made very good tech posts before,

I completely disagree.

I have left motors sit for quite some time. Here in moisture rich Seattle, with the exception of a HG failure, I have never seen oil-water mix that badly.

Something major is going on there... and he should keep looking until he finds it.

Personally,
I have had a HG failure not show on a compression test (all cylinders were within 5%, and it took an hour to get the test done; cooling down). Coolant loss was too slow to notice.
Still a month later, I ended up with cyl 1 scored badly enough to require a rebuild.

To say 'Ignore it, and it will go away' when working on your own motor is one thing.
To dish out that advice to someone else is completely irresponsible.


just my opinion though...

I have a similar problem, there is a small film of that goo forming under my oil fill cap. I've changed the intake gaskets and pulled off the valve covers but can't figure out where its coming from. I no longer have a PCV and all the crankcase gases are ventilated through a small hose (see pic) connected to a filter and the filler neck on the valve cover. Is that normal? I haven't noticed any coolant dissapearing or any in the oil.

I don't want to hear anymore "advice" out of you. That is terrible advice, all you ever suggest is that people throw money at problems without properly diagnosing them, because you had an engine do something similar.

 

[jammer84_03]

take the time to do it right...trust me. after rebuilding the last engine cuz of all the crap i had in the engine and the hg not sealing good enough. you'll save yourself a huge hassle in the long run. plus the bearings, rings and gaskets you'd keep paying for. but there is nothing like good research before you start pumping money into it. i had a warped head, plus the block was cracked....OOOPS!

 

[fastford91]

DUDE thats WATER and OIL ! tear it apart and find out where it is coming from! ill bet you $ 1000.00 !!!!!!

 

[BlooDReigN]

Interesting...Was the HG BLOWN or did it look normal when you took the head off, and it was just 'leaking' or was it just shot to pieces kinda thing??

Well, it wasn't completely BLOWN....I would still get a bit of compression in that cylinder...it looked like the gasket got burnt up a bit between a coolant passage and cylinder #3. The main reason I realized it was a head gasket is because it was causing tons of pressure in the coolant system. I thought it was just a hose that blew out at first...I fixed it and then it happened again. The engine didn't run like absolute crap either...It was kind of a weird head gasket blow.

BTW, I really can't see how a problem like THAT is gonna get caused by a bit of condensation...unless the ambient temperature is changing like 100 degrees a day or if you haven't changed your oil in years. I'd be glad I tore my engine down even if I found it wasn't a head gasket and found a simpler problem along the way. The amount of that crap in my lifters etc after VERY minimal time with the engine running was disgusting, and my intake etc didn't look half as dirty as yours.

 

[ozanracing]

That's it. I'm sick of this. No more BSing around. I'm ordering new Head gaskets, and intake gaskets. I just started the car today. Ran it around the block. I used the stock injectors. It immediatly settled into a perfect idle. But it felt, again like it was running on 7 cylinders when I started to drive it. I installed a new thermostat and gasket, new 16psi rad cap, new plugs, new ACT sensor (just for the hell of it)...So here's the odd part, that you will probibaly point out as a blown HG. The motor got up to temp (180*) and the thermostat did not open. I felt the upper rad hose and it was cold. The tepms shot up to 250* in a flash! I shut the engine off than started it again. thermostat opened, and the hose got hot in a split second and the temps went back to 180-185*. I drove it around again and it was sluggish. I'll Change the oil and take pics, it's brand new looking on the dipstick, and, no there's no "snot" in the valve covers, or heads, or the breather tube....There's alot of condensation in under the oil filler cap, and yes the water level is low in the rad. So I think the gaskets will correct this problem. Here's a pic of the #8 plug with another plug. They both have less than 15mins. or running time on them. After replacing the injectors, you can see the plug looks better. I'll continue to take pics through all of this, so if a certain one will help, let me know ant I'll snap it.

Hey...what do you think of those rocker arms? So far I hate them...they are the noisiest pieces of crap I've ever seen...and the lock nuts don't seem to work too well so far either

I didnt completely said "ignore it and it will go away" I was simply just suggesting for him to do more tests! Its just like anything else....when something is wrong you try to figure it out. The first couple pictures look like just percep water that was hung up in the valve covers.....after seeing the spark plugs i KNOW there is something leaking in the combustion chambers....percip in the valve covers or not, there is NO way for it to get into the combustion chamber. Once again i wasnt completely telling him to ignore it.....i was more saying, make sure you have a problem before you fix what isnt broken seattle is a moisture rich state, but put 105 degree temps on top of 90% humidity and you have oklahoma

 

[AnthonyR23]

that green stuff just looks like grease to me... you know the tube of grease you can get... ya ... like that stuff

 

[ozanracing]

Ya I just got these heads less than 2K miles ago. I can change the HG's pretty quick on this motor. I know WHY they blew. Because of the paint I used on them. I will never paint a HG again. You can see in the pics the S*** in the coolant passages, black/grey colored. I got down to the lower intake today, but had to drive to LA and back so I didn't pull the heads off today. I'll do that tomorrow.
Here's some updated pics. Maybe the mystery will reveal itself when the head comes off and we can inspect the gasket, but again, look close at the intake port on the number 8 cyl. Is this caused by coolant leaking into the cylinder?
Thanks for all the tech guys. BTW: Should I order new injectors also? Or just clean the S*** outta EVERYTHING from the block's decks up, and reassemle with new gaskets/oil etc and then read the plugs after? See if the #8 port/plug goes back dirtl/oily/etc-look-at-the-pics... I think that's what I'll do.

--------------------------------------------------------------------------------------------------
FIRST PIC, NOTICE THE WHITE SLIVER OF HEAD GASKET. WHITE IS THE ORIGINAL COLOR. tHE BLACK SPECKS IS OF THE PAINT I APPLIED TO THEM. IT LITRALY WIPES OFF ON YOUR FINGER IF YOU TOUCH THE GASKET. DOHH!!

REAR COOLANT PASSAGE

FRONT COOLANT PASSAGE

CYLINDERS 1,2,3,4,5,6,7 LOOK LIKE THIS:

THE #8 IS THE ONLY CYLINDER THAT LOOKS LIKE THIS: COOLANT LEAKAGE INTO THE COMBUSTION CHAMBER?

 

[ozanracing]

Here are some more pics from pulling the head. You can see the combustion pressure leakage. What kind of gasket for this motor? FPP-1011-1? Needs to withstand 6psi boost also, or 125shot...

Questions?

 

[ozanracing]

AHEM...Do you all agree with me on the blown head gasket.
that IS what I'm looking at here, due to the fact I painted them, right?
I ordered some MR GASKET ultra seal head gaskets, and fpp-1262R
intake gaskets, which I still need to know: Do those get installed dry, or with sealant?

Thanks, should have them by next wed.

OH!! Im sorry I didnt give him advice pacecar!! GD!! please tell me how many times you have changed these gaskets and have had this problem, please do!!

ozan, yes you have gasket sealing probs with the head, take it off and have it trued up if needed!! make sure to get good felpro gaskets to seal that bastage up!!

Yep, the HG looks like toast...

I gotta ask...
What made you decide to paint the HG???
