Would this let coolant leak into the crankcase? The spot between the bolt hole and the cylinder. Theres another spot just above the bolt hole. Would I be able to patch these with JB Weld?

I'm really not sure what I'm looking at. I have had coolant come up through the headstuds on big-blocks before though. in that case all I do is put some sealer around the studs and tighten them back up and never have the problems again

 

The way it looks in the picture, neither one of those dingsmake it to the end of thecylinder or water hole openings, so I don't see thatyou would have a leaker. But I guess a dab of JB Weld can't hurt as a little reassurance, and to help keep the gasket sandwiched flat.

 

i wouldnt put jb weld in there. it will ruin the threads when it drys if it ever has to come out.

 

to late.

didnt getany in the bolt hole so the threads are fine

 

We weren'ttalking about putting JB weld in the threads, but on the deck surface to smooth outthe two small dings.

 

Engine repair like this is always a matter of opinion. The repair you made could last years or even out live you. Since your done with your repair I can not help you but I will post my opinion so future searchs might find it.

I am curious to how that happened? IMO you are rolling the dice. I have used JB Weld to fix castings even engine blocks but that close to a compression ring? Can it handle that much heat? How well does it tranfer heat? I have seem JB weld fail when it was use to repair an oil gallary due to the heat and pressure. That was 60 psi and 250 deg.

I would have tried to work the area with a good flat file. Lay the file flat on the deck and work out about 3 inchs light even pressure. If I could not level it with .003-.005, which is about the max I would assume the gasket would take upI would have the engine decked. When you use a file like this your goalis to feather damaged area out like body work. The differents is looks by itself is not as important and you have to check yourself with a good straight edge and feel gages. Alsowhen doing this type of repair to keep in mind where thehead bolts are and try to workfrom the center of one out evenly that way the gasket can do its job and take up the error you just feathered out. IF you have no other optionsdue to costs I would lay the JD weld down let it fully curethen do the filing as stated above.

 

Thanks Gorn you helped out big time.
