[QUOTE=512_SIR II;2305133]So a sad, disappointing, depressing, set back of a day for me and my integra. I decided to drain my oil and pull my pan for the hell of it. Had no real reason to other than my friend and I were bored. Well I drained the oil and everything looked fine. I ran a magnet through it and there weren’t any metal shavings or flakes at all. I then went ahead and pulled the pan off. I then brought it out in the sun to see if there were any copper bearing flakes in it. After a few minutes of examining I found zero copper flakes in the pan at all. I was really happy at this point knowing my bearing were good. I then dumped out what was left in the pan and that’s when I noticed something was wrong. I found some thick dark gray slug on the bottom of the pan. I rubbed my finger on it and on my finger it looked more grayish brown and my first thought was “oooooh shit”. I grabbed a flashlight, got underneath my car and saw something that maybe my heart sink. I saw on that baffle thing that bolts to the bottom of the crank…bright green drops. I got that thing off the car and then I saw my rod bolts had milky white/brown oil on them. I looked up at into the cylinder walls and on the bottom side of cylinder #2 and #3 and I saw green drops hanging. I knew at that moment I had a major problem and that the head gasket was more than likely blown =[ Anyway enough talking, here are some photos of exactly what I saw
Bottom side of crank and rod bolts
This is the bottom side of cylinder #2
Topside of the baffle pan or whatever it is that covers the bottom side of the crank
I talked to a friend who has been building cars longer than I’ve been alive and he told me it could be a crack in one of the cylinder walls. That scared me. He then told me to set each cylinder to tdc, pressurize my coolant system and get under the car to check for new drips or leaks. I did this didn’t see any drips form or any leaks. The coolant system held steady pressure at 15 psi (which is what we set it to). This told him that there wasn’t a crank in the cylinder walls and that it was a head gasket leak. He also mentioned it could be that the head studs stretched and that allowed the head gasket to leak slightly.
The car has been down for a month or so while I’ve been putting the turbo stuff on. Before I put it down it ran great. I never had any issues with how it ran. It never smoked. I never had to add coolant to it. So my guess is this issue came up recently cause of that, and that the oil looked alright until I looked deep into the pan itself. The coolant also doesn’t seem to have oil in it. Not that I can tell at least. I have yet to drain that.
Long story I know, but I had to tell it. I’ve pulled my motor before, but I’ve never had this issue and I’ve never had to pull a head off a motor. This is gonna be a learning experience for me I guess. I’m glad I caught this before everything was done. It would of gotten way worse when boosted. I’m gonna find out what head gasket to get, arp head studs, and get the head decked since I’ve been told that has to be done when doing a head gasket. I’m broke as fuck, but if I can I’ll get the head port and polished as well.
I’ll post updates as things happen…ugh I’m bummed[/QUOTE]
Sorry to hear man but don’t stress too much. Head gaskets are very easy. If you want to keep it simple then you could leave the block in the car and simply pull the head, get it milled ( I think .005 is the standard resurfacing) and put it back on. The only issue I see is some possible scope creep (well X is out/apart so I might as well add X to the build). To answer some of your questions about the process:
You should probably add valve seals while the head is at the machine shop. The term “decked” refers to removing material from the block to bump up the compression, you just need the head milled. The best HG to use in your case would be the OEM Honda HG, I think they are around $50. You may want to get ARP rod bolts in addition to the Head Studs if you don’t do do anything to the pistons/rods. It’s up to you if you want to start replacing rods and bearings. Also make sure you do a compression check and leak down on the motor so you know the true state of health. You are lucky you caught this now and not something catastrophic on the dyno. Did the car ever overheat? Just wondering because Honda HG are not really that prone to failure. I am also curious of how that much coolant got into the combustion chamber without you seeing a ton of white smoke and if it did any damage to the piston walls or rings.
