OK, not quite blew it, but there is something seriously wrong with it; I had the up pipe off for porting and polishing, then I drove to the car wash and powerwashed the block (can't imagine this being bad, but I figured I'd throw it in just to make sure). I checked the oil level and started driving to Milwaukee. It was -20F and the roads were bad, so I went WOT maybe 5 times. When I did this, boost hit 22PSI (highest it has ever been) twice. I had race gas on, so there was NO knock. Power was awe-inspiring. I had to worry about spinning tires in 5th. 200 miles into the trip I stop at a stop light and the oil light flashes briefly; the car was down on oil by 4 Quarts! (I checked the oil immediatelly before I left). I top it off and drive another 130 miles. Now the car is down by maybe 2 - 3 quarts and there is a chocolate milk consistency substance sprayed all over the inside of my engine bay (dipstick popped out). I'm guessing that substance is oil mixed with coolant. Aside from that the engine runs perfectly fine and idles as normal. Compression is around 140 on 1 2 3 and 128 on Cylinder #4. The car is down in Milwaukee and I'm not sure what to do now. Any ideas?
he already stated elsewhere that's what he thought but that doesn't explain the massive oil consumption, at least i don't think just a head gasket would do that, but i'll let others with more experience chime in too
Wow, were the unicorns having a hard time keeping up then? :lol: I can only imagine what sort of wierd things pressure-washing an engine bay could do. You could be forcing dirt and grime deeper into things or washing away lubricants. Then to take it out in severe cold is just asking for that water to freeze and crack things. Run a leakdown if you can. There are also those kits that can test your coolant for exhaust/oil from a leak. That should narrow it down to head gaskets or not. Did you check the rest of the oil system for loose fittings, like the return line and such? Glad I got rid of my car before the head gaskets got bad
:roll: I don't think you are supposed to have lubricants OUTSIDE your engine, and if a 5000PSI turbocharged combustion event isn't blowing stuff out of the engine, a little jet of water sure as hell isn't going to blow stuff in. I checked and double checked everything before I went out... Plus I didn't mess with any oil or coolant lines, so I don't think its an external leak... I'm looking at all possibilities though; tomorrow hopefully I'll have a leakdown test done.
Well, you pumped out 6-7 quarts of oil in 330 miles, so something has to be wet. All that oil needs to go someplace. What does the dipstick look like (ie is there coolant and oil on it)? Russ
positive crank-case ventilation, vents the inside of the engine, if its plugged it will start sucking oil and crud through the intake manifold
Is your exhaust full chocolate of milk goop? Did you drain the oil yet? Chocolate milk is from oil and coolant mixing. The most common causes would be a blown headgasket, cracked cylinder wall or a water cooled turbo with a cracked center section.
positive crankcase ventilation... allows pressure to breath so dipstick dont pop.. among other things
some thing control valce. anyway, i would have to guess either that the power washer ruptured a hose, or else the water froze somewhere and causes a crack. i know this doesnt help at all, but i am trying to add to the thought process. could it be a seal by the oil/water pump? i dont recall if the two pumps line up exactly next to each other, but maybe the seal gave and is allowing the fluids to mix.
