Is this bad news???
put both heads on the 3.9 v6 Dodge but did not put the bolts in or
bolt them down. No pushrods in either. Everythign was clean and dry and the cylinders oiled before I put the gasket and heads on. Again, nothing was bolted down. For a few days I had been turnign the crank by hand seeing if the balancer was reading TDC, the rotor was pointing in the appropriate direction. Yesterday, I don’t remember why, but I took the driver's side head off. (Just lifted it off.) I think I did it because I noticed the outside of the head was wet with oil and I relaized I probably should have torqued the head down first before ptuing the rocker arms on. (I oiled the rocker arms and I think this wetness was from the rocker arms. Of course it seeped through because there were no bolts in the head. Well, to my dismay, the back two cylinders on the drivers side each had about a teaspoon of antifreeze on top of the piston. One of these is th episton that I found coolant in before takign the heads off. (I stuck winshield washer hose in the spark plug hole and siphoned it out.) Does this mean I have a craked block? Now worried, I lifted the passanger side head off and there was no coolant in that one. I convinced myself last night that the coolant was probably just due to the head not being bolted down and I recleaned everythign and bolted and torqued the head. But this morning I am not so sure. As a test before boltign the head down, I worked the crank several revolutions and did nto see coolant in the cylinders. I also but an air gun in a coolant passage in the block. Coolant came out of a lower passage but none I could see in the cylinder. (Pressure was not that high though). If the block is cracked I guess I will have to junk it. That would be disappointing. Also, after I torqued the head down, I pout the pushrods in and torqued the rockers to 22 ft pounds. When I grap the rockers and atempt to shake, some don’t budge, so have play and I can move them, is this normal? I really appreciate your help! |

No, it's because in turning over the motor without securing the heads, you've pumped antifreeze that normally flows from the block into the head and back down, out of the gap where they meet instead. Didn't this whole project start from a bad head gasket to start with? That's one of the reasons you have that gasket and tighten everything down to start with. Same thing with the oil--it has to get pumped up from the block up to the valvetrain somehow, and the gasket, held tight by properly torqued bolts, helps keep everything going where it needs to go. It doesn't just keep the suck-squish-bang-blow inside the big round holes. It is a carefully concieved and managed multipurpose device. There are consequences for doing things half way and out-of-order. This is one of them. You should probably pull the other head off and clean it out too, since it's equally likely to be full of stray oil and antifreeze. And who know if they've mixed, so after you've got it all back together, you'll want to change out both sets of fluids. You know, if you'd stopped over-thinking and playing around with all this stuff, and just did it the way the haynes/motor/chilton's book said, you have it back together and sold by now. Stop playing, put it together right and get on with it already. Or accept the consequences that this has become a big learning toy and may be completely unsellable when you're done. You know, most people who do that start with something small and cheap, like an old lawn mower or snowthrower... --Glenn Lyford |

You're going to sell this once it gets running, right? Bolt it up and run it. If it's OK, put the ad in the paper. If it's not, THEN figure out what's wrong.

Did you think to heck the heads and block for warpage while you had it open? There could be a problem there. Also, as you stated, you could have a cracked block. The reason that there is play in some of the rockers and not in others is the profile of the cam lobes. Once you get everything back together, if you turn the crank overslowly and check the play as the crank rotates through you will see that the position of the play changes. Jim |

Geezus, are you Still flogging that thing? . I got $100 sez it don't
