wpnsdog Posted February 23, 2014 Share Posted February 23, 2014 I am replacing the head gasket on an 88 with the 2.5. As I was pulling the head bolts, I found one that had a lot of rust on it. Any ideas as to what would cause that. Link to comment Share on other sites More sharing options...
benjy_26 Posted February 23, 2014 Share Posted February 23, 2014 Moisture.... but don't freak out yet. Last winter was pretty moist around my area, and I thought I was doing everything well when it came to driving and maintaining my vehicle. One day, while checking my oil, I noticed some weird sludge in my dipstick tube. I denied all evidence and told myself that I DID NOT have water in my oil. I changed it, and everything in the pan looked and smelled pretty normal. Checking it again a few days later, I found the dreaded "chocolate milkshake" on my stick again. I started flipping out.... until my brother had the idea to check the CCV system. One of the grommets was indeed clogged on inspection, and he noted that since my physical place of employment had changed, I was driving less than 5 minutes to work during a cold, wet season. His point was that my CCV's inefficiency combined with the low running time on my vehicle every mirning and afternoon were creating a situation in which the moisture in the ambient air was not being cooked off as it used to when I would have 40-45 minutes of highway cruising on my past commutes. All I did was to let my vehicle idle for 5-10 mins every morning and do the same when leaving work... Problem solved. :) That, or you really DO have water where you shouldn't. :-\ Link to comment Share on other sites More sharing options...
wpnsdog Posted February 24, 2014 Author Share Posted February 24, 2014 Related question: I now have the head back on, in my book it says to wrap bolt 8 with a sealant. Which one is bolt 8? Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted February 24, 2014 Share Posted February 24, 2014 It's the one towards the front of the engine . Your book will tell you the tightening sequence which will tell you where 8 is . My guess is the rusty one is # 8 being that is the one in contact with the antifreeze . I did all my head bolts as a added security to make sure they all sealed properly Link to comment Share on other sites More sharing options...
wpnsdog Posted February 24, 2014 Author Share Posted February 24, 2014 Thanks for the info. Actually, the rusty one was on the driver's side I think 3rd from the front. Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted February 24, 2014 Share Posted February 24, 2014 Could have been where the head gasket failed then Link to comment Share on other sites More sharing options...
