Engine Machining Can anybody recommend a machine shop in Southern California? I've got some burnt valves in my 29 Coupe and want to put inserts in the block. Probably hone the cylinders at the same time. Thanks

Re: Engine Machining I would call Arlyn Bieber at Hansens Model A garage in San Diego. Aryln does engines and they are schooled at all the mechanicals. I'll update back here shortly with the correct phone number.....

Re: Engine Machining Wherever you decide to go check them out in the archives here and on HAMB. The "&" symbol confuses the search engine so if looking for a company with that in their name go to Google and search for "X&Y on HAMB" or "X&Y" on fordbarn. Please post your experience as I will be looking for something in the future.

Re: Engine Machining I would go with Larrys pick as he has experience in this dept.

Re: Engine Machining By "inserts" I hope you don't mean you want to install valve seats. I would only do that if it is REALLY needed to correct excess recess of the original seat.

Here is an engine said to be from H&H.

Chances are if those two pictures go together, the second one caused the first. It would be interesting to see the inside of the block, and at what RPM the motor was turning when it came apart. Also would be interesting to see the details on the crank. From the picture it looks like a "B" crank with welded on counterweights and ground to "A" dimensions. There was a place in Lancaster, Adams Metalizing. They have done sleeves for me, not sure if they do seats. John |

The small piece they had added as a thrust bearing had fallen off and ended up in the pan. I took it back to them and they wanted $250 to fix it (reinstall the thrust surface and turn the crank). I junked the engine. They have changed this design in engines I now see at swap meets. New design looks better - -larger thrust area. The pictures below don't surprise me. |

I'm told unleaded gas is tough of the exhaust valves because it burns hotter. I have no data to support this, but the new valves are stainless, and stainless inserts don't burn like the stock block does in my experience. I have no idea why it's always been the first cylinder. Maybe leaner? |

IMO, fitting hardened seats in a Model A engine should ONLY be done as a last resort. I've never done it and can't see that I ever will. The OP is doing the right thing seeking advice before parting with his hard earned. |

Re: Engine Machining Quote:
BTW, I use a lead replacement in the fuel which doubles as an upper cylinder lubricant. |
Re: Engine Machining Quote:
Just my take Larry |
Re: Engine Machining There may be some terminology confusion here, I believe the OP wanted insert valve seats, not insert crankshaft bearings.
