[QUOTE=Davis31052;622050]Six Pack,


What method are you using to pin you cylinders? a bolt or a plug weld? I am interested in doing this myself as I have at least on cylinder liner out of place. I could see it had moved up about a 1/8 inch when I had the oil pan off last week.


I'm going to drill and tap and use a bolt.
I'm not sure which or how many sleeves are loose yet.
It'll probably be a few weeks before I start, but I'll take pictures and post them when I do.
I'm no welder, but trying to weld aluminum to iron and expect it to stay doesn't sound like the best option to me.

 

So put the block under the crank pulley.

 

I am.
Going to jack it up there, remove one mount, let it down, and see how stable it is.

 

Sixpack, be very careful you don't drill or tap into the water jackets and when you screw in the bolt be sure not to distort the liner shape even by a few thous.

IMO it would be best to use some pointed bolts with 90 degree angles on the ends, these can be turned up in a lathe and die down to release the burrs. Use a heat proof sealant on the bolts and be sure to use higher strength bolts minimum 8.8 or 10.9 on final assembly. The moral is 'don't rush the job' as errors can be expensive.

 

Yeah, I agree.
My Dad is a retired engineer, so he'll make sure it's done right.
Thanks

Bolt ends need to be flat though
