Twins / Re: A50 Pistons
« on: 27 October, 2023, 13:19:21 »
 :) :) :)

I know that A50 pistons are difficult to obtain and I think my last set were hells expensive. By the time you have paid for new pistons and rebore, its almost as cheap to have the engine resleeved/lined to fit the pistons. Dependant of course on wear and condition of old pistons. I had a Sloper done that way last year. However in this case I also had the piston refurbished to std.

I truth I dont know whether or no this would work in similar situations. My thoughts are that if you can fit rings below the depth/groove level that should be OK.  8) 8) 8) 8)Depends on usage but I would think OK for 20K miles or so.

Twins / Re: inlet valve seals
« on: 27 October, 2023, 13:08:20 »
 :) :) :) :)

Really only peripheral to this discussion. I was told many moons ago, that when reassembling heads, put a slight film of sealant around the valve guide under the lower washer. This will stop any seepage taking place at the valve guide/head casting joint. I've used it but of course its impossible to quantify its real use value. My thoughts are that I have nothing to lose by doing so.

As for valve guide liners of any type. To me that is preferable because it should retain the original spec more easily and it cannot place any stress on the " valve guide/head casting interface". It is usually cheaper and quicker. BUT use great discretion with open valves. In fact I know of a couple of engineers who will not fit them unless you sign a disclaimer and at least one who will simply not fit them to open valve engines.

As for the issue under discussion: no real idea and I've used or not used according to Head Type instructions.

These are simply my observations/thoughts and honestly not possible to prove either way

I often wonder how my old engines ran when I was much younger and didn't know about such things as ring gaps.

I would uggest your best way forward is to have new seats. If so its a short step to new guides or guide inserts. T&E engineering Bedford has done a couple for me over the years. They'll grind the valves in for you at the same time.

There are of course several reputeable machinists across the country who will happily do the biz for you. I would further suggest that such may not ultimately be that much more expensive.

Just a point on bolts 'bottoming out'.

I had the situation, self inflicted with a 'blow' front RH side of head. Retorqued started motor still blowing. Removed head checked to ascertain head and barrell were good--yep  :'Annealed gasket. Refit, re-torque still blowing. Removed the head dug around with a screw driver in all the bolts holes. Crap in the front RH corner bolt hole. Cleaned, flushed (this gets boring). Bolted up, started--- solved--- as I said self inflicted. It really is a B when you cant find anyone to blame.

For your info. At Southampton Hospital the prostate cancer staff used to hold a "forum" about every three months where like me who had it done could meet with those who were just going down the route.

I think its worth while checking if your area is doing anything similar because it was well worth while.

Take care

Whats the difference, I simply don't know and Im interested. They are doing three different bodies for the 389.

I think
1 1/8
1 5/32
1 3/16

Does that encompass 689 basic requirement.

Just my luck to have an extemely comely nurse remove the cathetter.

We laughed about it together.

Hi. Yes Ive been down that route, in fact we discussed it here a few moons ago.

Firstly I think age will have a bearing on decision. I am 82 and mine was done 9 years ago. I was given the relevant choices and initially opted for Radium(I think) but in less than an hour I changed my mind and went for operation. I could not live with the thought of living cancer cells in my body. So surgery it was.

I never asked about life expectancy at the time, but in discussion with surgeon a few months later I was told that prior to op I was about 18 months from incurable.

The one thing I would suggest is that anyone going down this road discuss with partner every step of the way because it affects them as well. My wife came to every hospital appointment so she was in the picture from square one. She did not 'interfere' in my decisiom but agreed with my stance.

I am told the various options affect ongoing sex life in approx the same way. The pundits will tell you that it should not go completely etc. For me it did so none zilch covers it. In my case a high percentage of the "urge" went with, I cant speak for enyone else.

One serious side affect is urination. For the first few months I could piss for England and I wasnt finally dry for about two years. In truth I still leak and need to use a pad whenever I'm out of bed. Fortunately I'm dry at night.

As you will understand this is personal and you may get a radically different story elsewhere. To me the loss of my sexual ability was a fairly major blow? the alternative was possibly death. So you have to decide your price. I would certainly make the same decision again.

Ultimately dead men can't F--k anyway. To me????? the op was a winner.

I hope this helps. Laugh--the gods have conspired. fingers up to the world.

I was in hospital about 30 hours. I came out with a cathetter fitted and a pee bag but only for about two weeks

May I suggest you go to the Boyer web site and have a read of their trouble shooting blurb. If it warrants it then send it to them for a test, They have always been obliging and fairly quick. I have no idea of the cost. I sent in one that tested 'duff' and they sold me one ex factory 'exchange' at a reduced price. Not recently I must confess.

Just a thought.

Further to post about A50/A65----- the manifolds are also different and its my experience that A65 manifolds are becoming incrasingly difficult to obtain. Just a thought.

I suggest that you check what the stud arrangement is on you barrells. The early models had 8 x3/8" studs and 2 x5/16th (Plus of course the short stud down in the pushrod well). Later were all 3/8". BSA produced a service sheet to modify the old barrells and heads. There are still some unmodded around. If you find a head with the 5/16th holes just drill them through or have them machined.However there was also a change to the valves at a later stage but I cant remember the detail. That is not a problem providing you use valves to fit the head.
I have fitted a very old head to a newer engine with no apparent problem, except as above.,

I hope all works out, it usually does.

I would braze that. It will add strength without distrortion and will shape easily. Gas weld would be fine. but more difficult to shape. Filler/solder will only cover it up, noy add to strength.
