Since assembling the E1 and into the running in that I did on the roll-around cart and after the reinstallation into Mighty Mouse, I've noticed puffs of white smoke off & on from the exhaust. I've probably got the equivalent of 700-800 miles on the motor now and in driving I've noticed that accelerating after pulling down speed using the engine to scrub speed, I especially notice a small white cloud. A couple of the plugs weren't wet with oil but pretty sooty with a good coat of soot in the exhaust outlet. Also noticed a gradual drop of oil level. I thought this out and decided that it must either be that I messed up an oil ring on assembly or had some bad valve stem seals. I didn't like the design of the oil seals that came in the gasket set but used them anyway.
The original seals had two compression rings, one at the top that compressed the seal onto the valve stem and one down low that compressed the seal body onto the outer diameter of the valve guide. The seals from the kit were of rubber compound only with a small o-ring in addition. The cup of the seal was a real loose fit on the valve guide. I had a bad feeling about this but assembled them anyway. After I observed the smoke and thought about it a bit, I contacted motorpowerinc.com and sent them photos of the originals and inquired what they stocked. I was pleased with the info they provided and ordered ten seals @ about $1.40 a pop. Their seals have a formed brass body that presses down onto the valve guide with the rubber part at the top cast onto the brass sleeve and a coil compression spring to force the flexible seal onto the valve stem diameter. Here's a pic with the original on left, kit seal in middle and the motorinc seals on right.
Took the rocker assembly off and plugs out and rolled over to TDC firing position on #1 cylinder using the hand crank. Sawed off 15" of 1/2 metal electrical conduit and poked two 5/16" holes to fit the outer rocker shaft studs for a fulcrum bar to compress the springs from. Had a fitting that I made years ago from an old sparkplug with the insulator knocked out and an air hose male fitting silver-soldered in that I screwed into #1 sparkplug hole. Made this tool out of scraps to compress the springs.
Gassed cylinder #1 up to 110 PSI & tapped the intake & exhaust spring caps a couple times to loosen the keepers. Hooked the tool up and compressed the springs, removed the keepers, caps, and springs. Here's a shot of it all in place on cylinder #4.
Here's a shot of cylinder #3 showing the seal from the kit on left and pretty much how it was positioned up off the valve guide. The Motorinc seal is on the right.
I highly recommend snagging a set of the motorinc seals if you're rebuilding an E or J-Series engine. I'll report back on the results of this little endeavor.

Reminds me of my 74 620 4X4. The 1800 engine blew smoke when you let up on the throttle. Bad valve seals were the culprit. Used the same air trick on the spark plug holes. I didnt have the nifty spring compressor tool you made back then!

I believe that there are a number of universal and also specific purpose compressors for assembled units, but I figured that I could whip something up quicker and with less blood-pressure escalation than locating and buying/borrowing something & it worked like a champ.
I can't remember, old age I guess, but I guess that I'd done something like change seals on an assembled engine in the distant past. Can't imagine otherwise why I'd have made up the sparkplug hole fitting which I've had for decades. My dad was a mechanic, upholster, bodyman most of his life, so we probably tackled some kind of disaster at one time.
Drove the 320 a bit yesterday with no sign of little smoke clouds in the rear view mirror like before.
I got my two hoods out and looks like the Mouse will finally get a hood back on. Gonna strip the good hood and get the neighborhood bodyman to work it over and match it up close for now. Then it'll be on to something else on this project. Gonna start looking for a good H190 in 4:11 gearing so the Mouse can grow some legs a little longer.

When you have completed Mighty Mouse would you consider helping with the US aging infrastructure? I know your talents would ensure that the bridges are straight and the strong!
I'll consider most anything, Keith, but the Mouse will probably never be completed unless it's by the next guy. 'Miles to go before I sleep'
I've been trying to keep the thought of another project to slot behind the 320, keeping in mind that I have to deal with the little wifey. Says I have too many projects already and I need to loose a vehicle to add a new one. So many vehicles on my 'Bucket List'; U320, V320, early FIAT 126, Steyer-Puch Haflinger, jazzed-up Chevy Chevette, & the list goes on in addition to all the non-vehicle projects.
I'll probably not be driving more than ten more years.

Cool upgrade. When I built my last BMC A series (1275 for my Sprite), I installed Nissan valves and modern stem seals to take it into the 21st century. It's fun applying modern tech to ancient engines.

RE: PHOTOBUCKET DILEMMA
If anyone is reading through this thread and wants to see photos of a particular post, PM me and I'll sent them to you.
I may go back and hook in some of the photos throughout this thread and, then again, I may not. Depends on how much recliner time I see in the next little bit.
I realize that many folks have a sore butt over the recent actions of PB but it is just a matter of economics.
You only get free milk for a time; then you gotta sneak under someone else's cow or buy a cow of your own.
Just the basic laws of nature.
I kinda figured out back in the 70's (psychadellic) days, that there are something like a dozen laws of Nature that control everything in life.
You can bend the rules; you can't beat them indefinitely.

I've only figured out three more or so.
But I'm only seventy years old, so I'm still figurin'.
I'll try to get those other three or so together & post 'em.
If I can remember what we were talking about tomorrow.
It's past bed-time for septagenarians.

I don't have a problem with what Photobucket did or even how they did it. It was always a known fact that eventually I would have to pay. I started paying and everything is fine. The main reason I don't like photobucket is because of how hard it is to use. It takes 8 clicks to get one image uploaded onto a forum. It's not flawless either. I often have to make adjustments and reload images.
That said, maybe I should start looking for another host that won't leave me stranded when my limit is reached.
I have printed to PDF whole threads before. Threads that if I lost, they would be very hard to recreate. It's a lot of work, but I have seen the writing on the wall and I won't get caught out...again.
