Hey mate, cheers for the reply. Yeah the cooler pipes look fine except for a bit of blowby. I ended up pulling off the intake manifold today and it's definitely coming out of the head...the inlet of cylinder 5 is coated in the stop leak I put in there a few weeks back. I'm on the lookout for new engines at the moment as I'm told there are a few other things that could have screwed up thanks to this. Thanks again.

Hi, I have recently bought a 1995 R33 Skyline and it was running great....for a while. A few weeks ago it started losing power and sounding like a wrx off boost, but on boost it ran fine. It started to chew up coolant like no tomorrow, with no visible leaks and then the last time I drove it, there was white smoke coming out the exhaust. And that was it, I thought the HG was gone for sure, but then I did a compression test and it came up with 150psi on all cylinders, but during the test there was water vapour coming out the top of cylinder 5. I pulled the intake manifold collector off but then I noticed coolant in the intake manifold for cylinder 5. There is also a bit of brown stuff on the intake of cylinder 6 and the intake manifold collector near cylinders 5 and 6. The bottom of the oil cap had also turned milky but when I dropped the oil out it looked fine (My poor royal purple) The spark plug on cylinder 5 is also quite black and it has only been in there for 3 weeks! Could this be due to a blown head gasket or maybe a water pump seal? Having coolant in the intake would be consistent with all the symptoms wouldn't it? Any help would be greatly appreciated, this has been by far the most hepful forum so far without a doubt. Keep up the good work! Cheran
