Showing results for tags 'head gasket blown'.
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!
Hi guys, I took my R33 to be tuned. The Tuner didn't end up tuning to a suspect headgasket leak after overheating. He said it pressurised the overflow bottle with coolant and has a constant stream of bubbles when trying to bleed the cooling system. I tried to bleed the cooling system myself and there are some bubbles after 500km of driving it so no air should be present especially after a fair few heat cycles. But not a constant stream maybe a couple bubbles every minute or so. Does this sound like blown headgasket? If so, can I get away with resurfacing the head, putting a MLS headgasket on and ARP headstuds? Can anyone confirm if you can take head off without taking cams out and reinstall it with cams in and fit the arp head bolts in? Can someone link me to an engine manual I can either buy or download? Much appreciated, can't wait to get car back on road. Thank you.
