So here's an update: I'm saving up money to purchase a new head from TOMEI so in the meanwhile I used JB Weld to fill the hairline crack in my head. It has been 3 weeks and not a drop of coolant has leaked from the where the hairline crack was. I was very iffy about using JB Weld on my cylinder head but to-date it has worked wonderfully.

Update: I did a compression test and a block test to see if any exhaust was in the coolant system. Block test: Negative Compression Results: each cylinder was done 3 times and the engine was warm. I did not have the throttle wide open during the test. 1. 160 2. 160 3. 160 4. 160 5. 160 6. 152

The blue 11048?

Thank you gents!!!!

Also how difficult is it to remove the head? 2 hour job or 2 day?

Great Information Shoota & GTSBoy. I was thinking of saving up some mula and buying a crate engine. I would save my current engine and learn how to build an engine so I can have as Mr. GTS PUT "have 2 of everything"! I'm learning about engines, all of the parts, and how they work. I tell you it's a lot to learn. I now will look up how the valves work and the reasoning for having them bigger and of course why have stronger springs.

Wow! Thank you for all of the technical information gents, I really appreciate it. It looks like I'm going to have to pull the head off. Question, would you guys get the crack repaired (if it's cracked) or buy a new/refurbished head?

No coolant where the spark plug is but around it, I've attached a few pictures. All other wells are dry

Thank you Trex, I'm glad to be here among such great enthusiasts:)

Prank & Shoota thanks for the great introduction to the site. I'm sure shoota is absolutely correct but prank if you don't mind please move it over[emoji6].

I shoota_77, thank you for the insight. I need to clarify my post a little bit. I bought the car in Dec 2014 when I was stationed in Okinawa, Japan. In May of 2015 I bought a rebuilt engine from a shop, the engine came with metal gaskets, tomei cams, r33 crank, N1 oil pump, new and a water pump. I added a power fc, R34 N1 Turbo's, 850cc injectors, tomei fuel rail, sard fuel regulator, oil relocation kit, oil cooler, orc super single clutch, big intercooler, aluminum radiator, boost controller, new coil packs, and plugs. When I retired Dec 1 1016 the Air Force let me bring my car to the US. My wife is going to kill me cause I have to put more money into this car...the Gtr life lol

Intro Hello SAU! My name is James but I go-by Jay. I hope the start of everyone's new year is going as planned, if not I hope it gets on track. I live in the US and I bought my 1991R32 from Okinawa, Japan to TX, so far its received a warm welcome. I haven't got a chance to push it yet because I have something going on that I hope you guys can help me with. I put it on the DYNO and found out I have a misfire. I opened up the spark plug area to remove the coil packs & spark plugs and all of a sudden I notice that I have coolant in 2nd spark plug well, where would it come from? I cleaned everything and put in new plugs and took in for a spin, the coolant came back :(. James
