Thanks for the video....getting my block from the machine shop in a couple weeks and will use your method of valve adjustment. It does make sense. I'll probably use the method that you state that you do one valve for every movement of the cam. Again...Thanks for the video.
I’ve just got a French engine that looks like the manufacturer date is 8/12/81 ( which if this is the date surprises me they where made so late) but just like the 8BA engine I have had no adjustable valve lifter’s, any idea when the adjustable lifters were fitted
Hello Anthony. My experience has been that the French motors always had adjustable lifters. That said, the ones I have had were always on their second or third rebuild. I don't know why yours doesn't, what is the history of the motor? Is the date a casting date or a rebuild date on the tag?
@@MartsGarage I assume it’s a casting date, it’s in portrait format on the back of the block , there’s no data plate attached. There’s negligible wear in the bores, the pistons are an unusual convex configuration and marked as + 38 ie one mil and the crank is a 4 inch and standard. It has an aluminium alloy sump which is not dissimilar to the 8BA one I have , I’ve not assembled it yet so not sure if I will be able to use it in my F1 truck but the 24v starter that came with it looks the same as my 6v one and bolts to the sump. The other strange things is that it has an aluminium alloy helical cam drive gear . Great videos by the way, may have to pick your brains in future as I’m not too familiar with these engines.
@@anthonyburdett2167 +38 is probably 15 thou over. as in .38 of a millimeter. Do you mean the pistons are domed? Anything else would be really unusual. Alloy cam gear ism normal. It should be cut so the cam thrusts towards the block.
@@MartsGarage yes the pistons have a ever so slightly higher dome in the centre than my 8BA ones, I just looked at the alloy cam drive gear and it has a 1990 date etched onto it, would that be quieter than the steel one? I can’t think of any other reason to fit one, I haven’t compared it to the 8BA one yet . When I get hold of an engine stand I will assemble it and see if I can use the aluminium sump in my F1 it looks pretty much the same size.
@@williambrown1031 No, Will, I wrote them on with a paint pen. The cam gear has a timing mark that aligns with a mark on the crank. When that mark is aligned with where the crank would be, No.1 would be firing, No.6 valves rocking. I decided that adjusting both valves at TDC on the firing stroke would be good enough. So No.1 gets adjusted with the mark at the bottom (On the spray can lid). then each successive pair of valves get adjusted at 45 degree intervals in a CCW direction, following the firing order. Mart.
Lots of good lnfo. Learned a lot. Thanks

Hi Ron let me know how it goes. I did two valves at each 45 degree "station".
How did it go Ron?
Mart, do you have a trick to adjust the valve without a lathe ?
No but there is a recent thread on FordBarn showing how one guy did it. Look for "Setting 8ba valve lash by grinding valve stems"

Interesting and relatively simple. What did you use to mark the 45* points on the cam gear? Thanks for the video.
Nothing tricky, Will, I just marked it lined up with the numbers already on the front of the block.
So, as I understand it, the firing points are stamped into the front of the block?

Ahhh! Gotcha' Sorry for my confusion--should have said block in the first question instead of cam gear. Thanks for your patience.
Are you going to adjust the valves by grinding them, or do you have adjustable lifters?
No adjustable lifters. Not grinding but turning in the lathe. The next video, due out on Friday will show how I did it.
What Motor oil do you use in your flatheads?? just finishing one and am curious....
Frank, I'm no oil snob. i just use whatever 10W 40 is on cheap at the supermarket.
Extremely 🤭
