psu_Crash Posted February 20, 2009 Report Share Posted February 20, 2009 So I went to retorque my head studs and noticed that the 2 front bolts labeled 11 in the FSM are completely missing!! I am 100% sure they didn't just come loose and fall into the engine. My theory is that when I changed the head gasket a month or so ago I just forgot to put them back in, or they haven't been there since the rebuild?? If they were here I can't find them. Either way what size/thread/length are these 2 bolts and what grade bolt are they? Suggestions on where to pick some up locally? Link to comment Share on other sites More sharing options...
Komeuppance Posted February 20, 2009 Report Share Posted February 20, 2009 Grade... 7... I think. They are 12mm. Probably almost 2 inches long... I think. Haha, check to see if they're in your oil pan. JK. -Robert Link to comment Share on other sites More sharing options...
Indiana Posted February 20, 2009 Report Share Posted February 20, 2009 Those are 8x1.25, its the head bolts that are 12x1.25 and they have a washer. Here, page 579 they are 50mm long http://www.b2600turbo.com/89i.pdf Link to comment Share on other sites More sharing options...

I know they weren't there Thanks for the help! This may be contributing to my oil leak where the timing cover meets the head ... I hope Link to comment Share on other sites More sharing options...
Komeuppance Posted February 21, 2009 Report Share Posted February 21, 2009 Yeah I was referring to the head size. Haha... I thought it was pretty funny. Has your head gasket been cut at the front?? -Robert Link to comment Share on other sites More sharing options...
psu_Crash Posted February 21, 2009 Author Report Share Posted February 21, 2009 Nope, it's all solid and I used gray RTV on the timing cover/head on the front end. I have no idea what's going on there but it leaks pretty bad. Link to comment Share on other sites More sharing options...
Technology Posted February 21, 2009 Report Share Posted February 21, 2009 I don't recall that they had a washer. You would have noticed a bunch of noise and probably engine problems if they had somehow defied gravity to come up and into the gear/chain area. Use more RTV around that area!

Indiana Posted February 21, 2009 Report Share Posted February 21, 2009 I don't know how they get the washers on there that do not come off, if they slide those on before the threads are turned or what but those have a flat washer that doesn't come off.

psu_Crash Posted February 21, 2009 Author Report Share Posted February 21, 2009 I picked up some M8 x 1.25 x 50mm bolts at work that are 8.8 grade with a couple flat washers. Probably have a chance to get them in there tomorrow. Going to take a look at the oil leak too. It wasn't leaking until I did the head gasket replacement not long ago and now it leaks like a sieve! I took my time and tried to make sure everything was sealed up nice there but apparently I missed something. (like those 2 bolts :character0285:) Praying that I will be able to see exactly where it's coming from and take evasive manuvers to get it all sealed up. Has to be a pretty big spot not sealed up for it to leak like that since there is no pressure there. It's getting nicer out by the day so I need to have this taken care of REAL soon and be able to get it on the dyno. I hear they frown on oil all over their stuff Link to comment Share on other sites More sharing options...
