idosubaru Posted February 4, 2014 Share Posted February 4, 2014 H6 3.0 engine has 60ish hex bolts for the timing chain cover. i am destroying almost all of them via chisel to get them loose. unless there's some compelling reason not too i'm going to replace them with normal bolts like transmissions/oil pan bolts.

Rooster2 Posted February 4, 2014 Share Posted February 4, 2014 Nothing exotic about a timing chain cover. Yea, I would use normal bolts. Recommend applying anti seize to the threads, just in case you ever have to remove the bolts in the future. Anti seize can sure make life a lot easier. I even use it on my lug nuts for the road wheels. Quote Link to comment Share on other sites More sharing options...
Bushwick Posted February 5, 2014 Share Posted February 5, 2014 You can replace them with traditional bolts, so long as you have clearance to extract with a socket or wrench. Anti-seize like stated above will help keep the bolts from freezing and help prevent future breaking or snapping. Just need a dab on the threads (don't over do it). 1 Quote Link to comment Share on other sites More sharing options...
ivans imports Posted February 5, 2014 Share Posted February 5, 2014 When I do stuff like that is critical you check that bolts do not bottom out in thread bore as this can cause cracks inside engine Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted February 5, 2014 Share Posted February 5, 2014 The only reason not to would be if there is limited clearance around the head of the bolt that prevents you from putting a socket on it. That size bolt should typically have a 10mm head. See if you can order a flange head bolt with an 8mm head for any bolts where there is a lack of side clearance.
