Re: Engine problem or normal?
While not ideal, a crack in that location (and other stud to water jacket) locations are not considered job stoppers.

Re: Engine problem or normal?
Although I have never seem a crack there (my "part number" cracks are always in their usual location), I agree with "Mart" that that particular crack is not a "game-stopper". While I'm no expert, I wonder if the installation of a quality thread insert ("Keen-Sert". "EZ-Lok", or some such)may not be a good idea.

Re: Engine problem or normal?
Maybe I could get more specifics on this. I’m ready to pull it and trash the block because I thought it was no good do to this issue. I’m getting exhauste gas into the cooling system, motor is in truck and didn’t think I had other options?

The post above is the first mention of exhaust in the coolant. Mart. |

Re: Engine problem or normal?
Under the deck the material is round and then becomes the exhaust runner.
Not to uncommon that deck and exhaust splits when it cracks in the thin part around the stud...and exhaust is coming up into the coolant. That can be fixed with a longer stud or thread insert. If the cracks showing goes straight all the way down into the exhaust it´s more of a challenge. |

Re: Engine problem or normal?
I don't know if I would rely on the exhaust gas test. I had a friend who had a positive test. He removed the engine and tore it down to build a new block. I pressure tested the old block for him and found no problem. I rebuilt the engine and it has been running for 2 years with no problems.

Re: Engine problem or normal?
I don't think the little coolant lose is a issue ,they do drop a little as has been said you should be focusing on if its over heating or not ,its not wise to pull a motor to bits with out doing some testing, you put a catch can on the tube and see how much you get .A thermostat can add to your problems not nessarly help .The oil pressure I have a simler problem on a merc block, 5 at idal 15 at revs , so Manual gauge goes on next ,Ted
