Hello i have a problem i have a B18 turbo with darton sleeves.
I went a few days ago on the dyno and i got 700HP on the crankshaft.That's about 613 HP on the wheels, i have 630 Nw of torgue.
I pulled two runs on the street and everything was fine the boost was nice so i was happy.Got the car on the trailer and went home, put the car in the grage.the next day i wanted to check my fluids and saw that i had oil in my coolant.Can any one tell me what the problem is.

I'm scared that my sleeves dropped,or is the gasket of my head that is leaking.Cause if my sleeves dropped i have a huge problem what means that my whole has to come a part.

Hope that somebody had the same problem and can tell what it is.

It could be either one. The only way to find out is to pull the head off and check it out.

 

Your problem is that you have oil in your coolant and are scared to pull the engine apart.

 

Best to open it up and check it out. If I had a lot invested into my motor I would want to know wtf! You could start with the gasket and try that but if you think a sleeve dropped and you want a warm and fuzzy then it is best to get eyes on.

 

either way the head is going to have to come off.

 

I have had the factory oil cooler leak on me before and I thought all hell had broke loose. if you still have it check it out.

 

A leaking oil cooler would deposit oil in the coolant?

 

I would do a leakdown test on the engine, up to temp ( or as close as you feel ) with the radiator cap off with a spill-free funnel. Then you can tell if its the headgasket or not with out tearing down the motor. If you have bubbles on witch ever cylinder you are on then you have found your problem. If none of the perduce bubbles the start looking else where.

 

I had a Darton sink. Blew head gasket right away. N when I pull head u could barely feel the lip where it dropped. So wasnt much. But head gasket blew out hard lol. So mayb ur lucky. But pull it apart . As stated.

 

You didn't need to make two threads.

Do a comp/leak down.... if its bad pull the motor apart and inspect it.

"Barely feel" when it comes to racing engines is A LOT.

Stop ***** footing around it and just do it. You have a problem which involves at minimum taking the head off anyway since you've got oil in the coolant.

 

Is there a lot of oil, or just a slight film? Does the oil in the oil pan look like a chocolate shake? Is the radiator being reused from a previous build that blew up?

If you still have good compression in all 4 cylinders then its likely NOT a dropped sleeve. A simple compression test and leak down will tell you that info righ away. No need to pull apart the engine if it passes a leak down and compression test.
