So I need your guys opinion. Latest on the X19 b16 is we have a warped/cracked head or a blown head gasket.I am going to leak down test it to verify, but it is really pointing to that being a big cause of not being able to keep the engine cool.
If this is true, I have a few options. Wondering your thoughts. From most expensive to cheapest.
Myself, I am leaning towards #6. We know the head is straight as we drove the honda about 45 miles before we took it out for the swap.
All of this can be voided if we find there isn’t a leak. But running out of what else it can be. Water pump cannot be replaced without pulling the engine so I am hesitant on doing that simple one. Plus here is the reasoning I have that it isn’t pump related. Bad pumps don’t usually work intermittently. Last weekends results were as follows. New high performance aluminum radiator, new hoses. Filled it up, burped it a couple times. Went inside for a bit to let things cool after burping. H2o was hitting 200 then I would shut it down, burp it, and restart it. when it restarted it would be high 180s. it would go to 200, stop, burp and do it again. When I didn’t get a burp. Is when I stopped. Went out started out at 120. I let it idle only. It climbed to 196 at stayed. 15 minutes of 196, the radiator was HOT telling me there is circulation. Bliped the throttle up to about 3500 5-6 times and the temp started to climb shut it down at 205. Noticed my fans didn’t kick in. ok. So I need to drive it to get airflow. So I started it back up about 195, drove down the road and it whent right back up shut it down in the driveway at 210 and coasted up the drive. Got out, and the radiator was warm, not hot, warm. Telling me no circulation. When to burp it, and sure enough there was air. So my thought would be the leak isn’t noticeable at idle but revving it up pushes exhaust into the coolant system, air pocket. No circulation. Also would account for the quick warm up to hot, (about 5-7 minutes from 78 to 200. While running it faster than idle.

- Build a b20 vtec turbo charged engine. where i eventually want to end up
- Build a NA b20 vtec
- Buy a jdm b16 longblock (startup warranty)
- Full rebuild of either current b16s
- Bottom end only rebuild on 1st b16 the one with spun bearings.
- Put 1st b16 head on 2nd b16 engine. Does NOT have to come out of car. use ARP studs OEM gasket
- IF lucky and block and crank are not destroyed on 1st b16. Swap bearings only
