I.e. original tools, no rtv and no Phillips. I milled the head at home. I used sandpaper taped to glass and I shaved the head. I used dykem and sanded until there was no blue. The was was fairly flat. Progress!!! Who needs it? 1 1 Link to comment Share on other sites More sharing options...

Mattml430 Posted April 13, 2023 Share Posted April 13, 2023 This video will give you an idea why you can’t have a bent anything in an engine, and it’s running freely with no compression or explosion. Put those 2 into the equation and you can only imagine the load on engine components. 1 1 Link to comment Share on other sites More sharing options...

Oh jeez, tell me you’re not cutting and lapping that valve with everything else exposed. I don’t think your rings will need extra help bedding in! 1 Link to comment Share on other sites More sharing options...

I don’t think your rings will need extra help bedding in! That’s exactly what I am doing. I’m doing a valve job while the head is off. I cut the bad seat and lapped that valve. I then removed the pin on the other valves so I can lap them in place. Link to comment Share on other sites More sharing options...

Mark Gregush Posted April 20, 2023 Share Posted April 20, 2023 All the grit from the stones and metal filings is being flung into the cylinders. You should have rags in the cylinders and covering the open valve(s). Any wash down will just get down into the cylinders and sit on the rings. 1 Link to comment Share on other sites More sharing options...

Mattml430 Posted April 21, 2023 Share Posted April 21, 2023 So maybe if the engine was seized the rings could possibly just possibly be stuck in the ring grooves. At least there is a chance all the crud, dirt, dust and metal shavings can slip past and get down into the sump so it can go through all the bearings. 1 Link to comment Share on other sites More sharing options...

JACK M Posted April 22, 2023 Share Posted April 22, 2023 I get the idea of a light hone. But I think if it were me, I would use the ridge reamer and call it skippy. I have a feeling that this engine might not run very long anyway without at least pulling the pan, then the pistons so that you could do a light hone and a proper clean up. Most of these guys that are commenting here are cringing. Rightfully so as we that build an engine on occasion are into clean and precise. On the other hand, it might run longer than you need it. Who knows. Best of luck. 4 Link to comment Share on other sites More sharing options...
