GSX down, and possibly for sale Options

[90GSX]

Well after all the happiness of having it back running, on my way to work something gave out. Im guessing headgasket. It was making all sorts of loud noises coming from the head and lifters, and going down the road it drove ok, but lacked power and not getting the turbo to boost any more than about 1 psi, and even when i floor it it would barely speed up any, so swing it around and baby it home (approx 10 miles total) i check my oil and its all really watery. I must have caught it early cause my overflow tank still has coolent in it, and it never even got hot. The car will start fine, and doesnt seem to have a miss to it. So my guess would be headgasket or maybe blew a turbo seal? Is it possible for it to blow one just out of the blue, no warning on the turbo? I only have 100 miles on this rebuild and i never drove it hard at all, stock boost levels, and never revved over 4k yet. It ran fine up till last night, and now im not sure what to do. I am at the moment carless. Guess i will call the guy who rebuilt it and see what hes gonna do about it if it end up being a headgasket. Anyone know how to test this? Can it be bad, but still hold compression?

So, i am open to any offers via pm to see if anyone wants a cheap AWD fixer upper. Lots of new parts, and rebuilt motor and im gonna end up taking a big loss on it, but i just dont have the energy to tear this apart again. Im not sure what this would be worth if its just a blown headgasket, but if the price is right, im willing to let it go. Trades, cash, trades and cash, or if anyone has a cheap DD emphasis on the cheap, let me know. Thanks

Well, since coolant in the oil is out of the question and compression is on the up and up, I would assume you've got a boost leak / a spark problem / or a fuel problem. Take a quick log if you can and post it. If not, pull the plugs and ground them to the valvecover while having a friend crank the ignition. Watch them all. Spark should be defined and very evident. If not, you're problem is spark.

If not the above, do a boost leak check. This is probably the easiest of all the checks. Get yourself a boost leak tester and do the test. This is quite possibly your problem.

Or, pull your injector rail and hold a bucket under the injectors and just turn the key to the ON position (don't crank it, the injectors will fire when they get to the ON position) and watch the injectors. They should all spray a fine mist and be firing evenly. If not, replace the one that doesn't belong.

That should get you started.
