Good day guys, so I've finished doing a couple of mods on my RB20DET GTS-T, got a base map put on to my Nistune ECU and now unfortunately on idle it blows smoke out like crazy. It was smoking slightly before i pulled everything apart but I had thought it was the turbo seals hence why i replaced the turbo and a few other things.
4" Straight through exhaust doesn't help either I can imagine. Symptoms include on start up generally after about 15-20 seconds she starts to smoke white clouds, as she warms up the smoke intensifies. I've done a compression test this morning and the results followed from cam cover to firewall, 150/140/145/145/150/150 PSI.
I am leaning towards maybe the head gasket might have a crack in it or blown. But not enough evidence points towards this maybe?, No mixing of oil and water within the engine, I can say she's taking a bit of water not from the radiator but from the overflow tank.
I don't mind pulling off the head to do a head gasket but bloody annoying since i just put the dam thing back together and thought it was ready for a dyno tune.
I have ordered a leak down tester tool just waiting for that to come in, but welcome to any suggestions and theories or experience from you fellow members all input is appreciated cheers guys!
