Okay guys..
I am doing a transplant into my austin mini.
I have a d16z6 that I am installing in the car.
There was a leak with the aftermarket chinese POS intake manifold at the bypass outlet. There was a pin hole and it leaked antifreeze.
So i took it off and sealed it. I used the same intake gasket because it was new and only has 3-5 mins of run time on it. Since I am still in progress of installing the engine I haven't gotten far with running the used engine.
So.. I put intake back on there. and started missing a little. Then white smoke.
Then antifreeze from my radiator was dumping into the oil pan. (foamy oil/coolant mix 6 inches up the dip stick)
So i took out all of the spark plugs and 1,2,4 look great. Cylinder 3 has oil on plug. There is also oil flowing down the header from this cylinder.

I then blew into the radiator and more foamy shi.t started to flow out of the dip stick tube.
There is no oil in the Coolant. Just coolant in the oil.

Is this from the intake manifold gasket ? possibly?
OR... Head gasket...........

ehh, i'm def thinking HG.

if there was a major breach in that garbage intake mani and coolant was allowed to just pour into a cylinder...and sit...and leak down past the rings into the oil, then i could see some contamination of the oil with coolant. but the breach would have to be pretty big, in my opinion, and there would have to be ample time with the engine OFF for the coolant to collect and leak past the rings.

the problem here is you are stating there is oil on one of the plugs and there is oil running from the head/block mating area down a header runner, so adding up all the facts to me it sounds like you have compromised the head gasket.

Hmm..
Here is a couple odd things....
Intake Rail on cyl 4 and 3 have back flow of foam oil/coolant mix..
Cyl 3 had oil on the cylinder but not Foamy... No foam mix and all other 3 cyl are perfectly fine.
But..
I blew into the radiator and foam sh.t went up into cyl 3.

Okay..
Pulled the head last night...Cylinders look good. Valve on the intake side of number 3 cylinder leaks a little.
Oil residue exhaust port cyl 3. thick coat of it.
Cylinder sleeves look good.
Antifreeze in water jacket around cylinder sleeves looks brand new and cleaN!?!?!
The head gasket so far shows no problems.. i just have to check it out again or have someone else look at it..

i'm going to move this to 92-00 so more eyes will see it. the d16z6 subject makes it a legal move IMO.
