Hey guys. b20vtec. Fully built GSR head, BC4 cams, Omni power valvetrain, blox lmas, Skunk2 gears, hondata intake gasket. RS machine pistons, stock b20 rods with ARP bolts, ARP head studs, golden eagle conversion kit with GE OEM Honda head gasket, stock bore 84mm on a fresh hmotorsonline b20b block.. Skunk2 intake manifold with skunk2 70mm throttle body. Hondata s300 from Phearable with a premium basemap (running AEM wideband) with walbro 255 and 104 octane (torco) Anyway.. Compression test results-. 225 psi in cylinders 1 and 2, no drop in psi at all... 3 and 4 reached 160 then lost all psi through the throttle body (could hear it seeping out) to zero. Car runs great on the basemap, pulls very hard and stays within the parameters on the wideband. Pulled the oil feed line into the head off today and the oil was a yellowish/greenish tinted color, I was very surprised to see it like that.. I'm thinking I have an issue with the head gasket and or head.. head was checked out by local machine shop and was fine.. also the oil in the pan is starting to get kind of milky also, and smells like fuel is in the oil..?? I'm confused but I'm pretty sure I will have to pull the head.. here's a pic of the oil feed line disconnected from the back of the head and the discolored oil.

 

I pulled the line originally to see why it was slowly leaking oil and found that the Teflon tape had been pushed back away from the threads, it does not leak now. But I noticed the discolored oil and now Im alarmed of a possible head gasket issue.

 

Looks like you are mixing oil and coolant/water. Pressurize each cylinder with compressed air and remove the radiator cap... look for steady bubbles. You can also pressurize the cooling system and look inside the cylinders themselves and see where coolant starts coming in.

Good luck.

 

Alright I will give that a try after work tonight. Thanks for the input!

 

Which head gasket ru using, definitely looks like oil and coolant mixed like the head gasket is blown. It's new so maybe it's not the right one, I don't know which one is the correct one, just making an educated guess here. I plan on building a b20 vtec as well. The oil pump in my b16a went out and I'm a use that head on it for my b20v
