'77 550F Engine tear down and rebuild question
« on: August 05, 2017, 05:57:55 PM »
Hey everyone. I figured I'd come here, take a break and ask a question. I'm at the point on my rebuild where I have cleaned surfaces, installed new valves and valve guides, and new piston rings. I have successfully got all four cylinders into the buckets, but my question is this....how come I am having trouble getting the cylinder head to go all the way down? I don't want to force anything and risk damage. I feel like I've done everything correct so far. Any insight would be great, thank you.

Edit: it's about an inch maybe inch and an eighth away from mating to the crankcase.
God I hope I have all these component names right for the engine.

Yes seats were recut, I'll check out if it could be the cam chain tensioner. I'll take a picture and up load in a few min.

calj, I am a total idiot. It was something as simple as just rocking the head a little and giving it some loving to get seated. I apologize for not doing this initially and taking up space on the forum. I will post when I have an issue worthy to ask.

That's funny! No I just feel like such a noob on this stuff, and I mean I guess I am. Next time I'll work out my issues instead of crying wolf ya know, but yes onward! and I'm gonna substitute 6 beers in place of the soichiros, so all in all i think it pretty much pans out.  ;D

Always better to ask and discover a very simple solution than to forge ahead without confidence and tear something up.

+1 don't worry about hurting anyone's feelings here, we waste our *own* time here, that's no on you OP  ;D

Heh! well I'm about to waste even more of my time. I hit another snafoo and one that I can't figure out for the life of me. I was tightening the engine nuts to the engine studs, and had all of them right at 15lbs foot torque and I go do the last one and snap, and that little bastard broke, which sucks but that's not my biggest issue. Currently, I am trying to take off the cylinder head so I can address this situation but I am having a heck of a time trying to get the cam chain guide out. It has play but it won't go above those slots so I can turn it and remove it. I'm gonna ask for help on this on because I need to walk away for a bit and not be in the same room as that motor. I just don't understand why it went in there nicely and the correct way but now it's being a pain in the butt.
