Re: Khan's Motoring Chronicles
You should check the old head bolts that were on the same side as the crack to c if their stretched. Looks like a stress crack to me from over torqueing. Also might of had a bad head gasket, some water snuck in and hydraulic lock and split.

I have been using one with a rip in about the same spot as Khan's and its held fine for 2 years now.online170 said:

... that's why
because a $1 is not really a $1 part around here. And it's not really $1 when no one around here seems to have one in stock. And the long weekend is coming. And $1 can easily turn to $30 when you order online and have it shippedonline170 said:

Re: Khan's Motoring Chronicles
we think at some time in the engine's life, there was a headgasket leak, which caused the split. But my gaskets were fine when removed, so it leads us to believe it's a past issue.
the old bolts didn't appear overly stretched over the other's. And doesn't a stress crack from over torquing happen at the bolt location? This crack is far away and inbetween the two cylinders.Pontiac455 said:

the joys of living north of the border..
and I've repaired gaskets like that before...no problems

Looks good Khan, definitally jeliouse 8) . Where or who did your machine work?

Re: Khan's Motoring Chronicles
a local CarQuest runs a full machineshop out the back. The machinist there is very well experienced and does great work for reasonable cost. It's hard to meet him for a short time because he knows so much he goes off on tangents and has something to teach you every time you go. And even tho he works for CarQuest, he looks out for his customers and gives advice on how to cut costs.
there wasn't much machine work involved with mine. He honed and prep'ed the block and assembled the rotating assembly. Bill was higher than planned because I had him file fit the rings and he ended up ordering the valves seals with a nice CarQuest markup.

Re: Khan's Motoring Chronicles
another update...
I was having a hard time with the intake bolts. They were allenkey bolts, but my allenkey socket was too fat and hitting the intake in places. Kept turning crooked and stripping the bolts. So to hell with that I used normal bolts and it worked great.
then I got the fuel pump on and cleaned my valve covers and put them on with the new gaskets I got
Motor was looking pretty good
someone suggested I should hookup the cooling system, pressurize it, and leave it overnight to see if any leaks develop. It was sort of a messy process
I left it over night and this is what I found the next day
I was pissed... Took the intake, water pump, and heads back off. Found water in the cylinders and the deck had started to rust. And there was a small rust spot left in cylinder #8
The rust on the deck came right off. I've tried to clean the spot in the cylinder but can't get it all out. It's very faint and above the rings, so I'm hoping it won't cause issues.
I did some reading after and consulted a few people. The 20psi I used was too much and likely caused the leak.
Head gaskets don't fully seal until engine runs and bit of heat cycles thru them. And the intake and water pump gaskets are never meant to see those kinds of pressures. I also think I didn't use enough thread sealer on the bolts.
The head gaskets looked fine so I cleaned them and the deck & heads and installed the heads again. I used liquid Teflon sealer this time which is very thick and goopy, and I hope it seals better than the greasy type Aviation sealer.The gasgacinch sealed the intake gaskets well and I couldn't save them. New gaskets are on their way and I'll re-install things once they come.
The block has factory deck and is not the straightest. But there were no issues before, and there shouldn't be now. I hope it was only my excessive pressure that caused the leaks.

Re: Khan's Motoring Chronicles
is that a drop of coolant? I never use anything but water to check a new engine for leaks, water won't harm anything if there is a problem...
