ktm Posted November 6, 2007 Share Posted November 6, 2007 I took my car out for a spin tonight and it was acting very strange. I came home and ran a compression test. Just as I tested #6 first, #3 blew a geyser of coolant all over me. I continued my testing and my compression numbers were 120 to 130 across the board, with #3 at 150. So I pulled the rad cap and tested all the cylinders. EVERY SINGLE CYLINDER caused the radiator to overflow. However, only #3 shot a geyser and #4 spit occasionally. I'll be pulling the head later this week, but I am seeking some ideas as to WTF happened. Quote Link to comment Share on other sites More sharing options...
locodrftr Posted November 6, 2007 Share Posted November 6, 2007 Hmmm sounds like the headgasket....i dont suppose u see any coolant or anything just below the spark plugs? right where block and head meet? mine has a slight sweat through there and im guessing my block needs to be decked....what motor and mods do u have?turbo? and what was going on when things started to act strange? im sure some of the veterans on here will surely help u out....

Administrators RTz Posted November 6, 2007 Administrators Share Posted November 6, 2007 Bo, I hate to say it, but the heads gotta come off. Its either the headgasket (likely), or a cracked head (unlikely), or cracked block (very unlikely). Sorry Chief, Quote Link to comment Share on other sites More sharing options...
gogriz91 Posted November 17, 2007 Share Posted November 17, 2007 I may be in the same boat, compression test had 160-175 across the board with coolant in the #3, I'm praying it's the headgasket. BTW, I'm looking for options besides an N47 if the current head is toast. Quote Link to comment Share on other sites More sharing options...
ktm Posted November 17, 2007 Author Share Posted November 17, 2007 Have the head checked. While mine was not cracked, it was definitely warped (0.02" out!!!!). Quote Link to comment Share on other sites More sharing options...
