Okay I have replaced my engine, heads, and intake trying to get rid of the coolant that keeps getting in my oil. I did a coolant pressure test and it looses 1/2-1 PSI over 2 min. When I run the car for about 15 sec and pull the radiator cap there is tons of foam which is the signs of a bad head gasket a heads gasket. How in the world is the head gasket blown if its brand new engine, heads, and GM head gasket. I also torqued the heads to spec and used permatec 2A on the bolts. Is there something I am overlooking??

I don’t have an air compressor so I can’t do a leakdown test.

 

I just drained the oil for about the 7th time in 150 miles. This time I put about 30 miles on it and there is a slight trace of coolant in my oil. Tons better then before I changed the intake. I have changed the oil and filter about 3 times since I have changed the intake so it is not just residue left over. How can i figure out where exactly it is coming from?

 

Also the coolant pressure tester bounces a 1-2 PSI when I rev the engine up to ~2000 rpm, is that normal?

 

do you have a new intake manifold? If not ,get it checked for cracks.

 

man, i hate reading stuff like this.
it always makes me skurd to start my car when i'm done.

 

Do you have any new pics of the oil?

 

Yup brand new.

I tried taking a pic but it won’t show up since there is a lot less antifreeze in the oil then before i changed the intake manifold. I have to take a screw drive and stir up the oil to be able to see it well.



I got fed up and bought an air compressor today to do a leak down test only to find no one sells leak down testers near me except Napa and they want $110! I have seen them on ebay for $40. Anyone know a good place to buy a leak down tester or has anyone built one?

EDIT: I built a leakdown tester today, you can see it here: https://www.thirdgen.org/techbb2/sho...hreadid=248479
I will do the test tomorrow and see if find the problem.

 

That perfectly descrbes symptoms of my oil. I always associated it with metal in the oil. It seemed to make sense in my case because the condition got better and better with mileage, at 8k mine is almost gone. I never really thought about it, just changed the oil every 1500 miles. I also have had two sets of heads and two different intake manifolds on the engine, so I'm pretty sure I had no coolant leaks. We need someone in here with personal experience with only metal in oil, only coolant in oil, and both metal and coolant in oil.
