After about 1.5 years of slow going I fired off the 2056 today. It ran great once we got the timing spot on. Man did it sound mean! Left a nice little puddle at the end of the 20 minute cam break in from the rear main, so I have to pop the trans off and see what's going on there.

Thanks to all those who have helped!

I'm sure there are others! It's running happily at 2000 RPM's here...

Congrats make sure to set the carbs up correctly, you will be happy you spent the extra time.

how did you set the electrical up for the start outside of the car?

nice work man!

I had a switch that was wired to the coil and the fuel pump. The power side of the switch had a stackable connector so that the incoming power lead could power a trailer light that acted as my idiot light (always on). The power lead was connected to the starter with a ring terminal. I had jumper cables attached to the starter and the ground lead on the trans - they lead to a battery.

All the grounds (which I think was just the fuel pump) were attached to the case ground pick ups (those 3 pronged things). I used a HF remote starter to start the car.

I can either draw it out or take some pictures if you like.

Anybody care to take a guess why my rear main seal failed?

Because God hates 914's?

Yes - I can attest to this. I asked him on the telephone one day and he told me this very thing. He did say he has a soft spot six cylinder engines - the one in my car in particular. So I got that going for me...

Great... Thanks for nothing guys.

You need to verify the thrust on the crank.
The little washers that go behind the flywheel are important.

Take the tranny off.
Set up a dial gauge on the face of the flywheel as close to center as possible.
Take a rubber mallet and hit the flywheel forward, set dial indicator to zero
Take mallet and hit fan HUB,..the middle , backwards.
Take reading on thrust.
Read manual to figure out if its in spec.
Get new washers and felt pad for behind the flywheel.
Take flywheel off and put in new oil seal, washers and felt.

While you are at it...check the bolts for the front fan hub and make sure they are the right length, not to long and not rubbing the front seal.

You from the Washington DC area? Where'd you get the 9:30 club shirt?

Not all main seals are the same. I have had this problem a few times. Now I check and triple check the fit on the flywheel before the main seal gose into the case. Also did you put a little grease on the two surface's before matting them?

Over time you can get a wear groove into the flywheel not easy to spot but its there.

If you need a hand call me 818 266 7774 I am 12min away.

Yup... Grew up just outside of Annapolis. That is an OG 9:30 Club shirt - back when that was their address - 9th and F Streets if memory serves...

HeelToe914,

I'll give you a ring either way. It would be nice to meet.

I just ordered a new rear main seal and flywheel o-ring from Jake. I'm hoping his stuff will get the job done.

Any techniques for actually driving the seal in and how far does it go in? On Jakes video he just lightly tapped it in with a rubber mallet, so that's what I did...

Yeah the old place was quite the hole...but good shows and that's all that counts.

I think some of my clothes may still have the "9:30 Club Smell"...

OK... Now I'm a bit confused. This is my first Type IV, but the flywheel seal and surrounding area looks dry and good. I'm thinking that the oil galley plugs that my machinist put in may be leaking. He used yamabond and there appears to be voids in the sealant.

Here is a pic of one of the plugs with some of the Brad Penn oil on it. The yamahbond is white/grey and the oil is green (unfortunately so was the case sealant i used...)

Here is a picture of the flywheel seal... Seems dry down past the cam plug.

Here is a picture of the bottom mating edge of the case to trans. It's wet in the red circled areas. Again, the oil is green and so is my sealant (Curil T).

And finally where most of the oil was collecting - along the bottom seam of the case between the oil strainer and the tranny. There was oil up in the tranny, but *not* on the flywheel, PP, or clutch.

I'm stumped...

Looks like that seal may be to far in? call me we can look at it all but plan on redoing the plugs & seal. why not your in there.

And the oil galley plugs were the culprit. When I backed out the one on the right it had maybe 3/4 of a turn of yamahbond on it... I removed bot small plugs and redid them with the Loctite 545 that Jake sells. Dry as a bone!

Thanks to Leamon for coming over to lend a hand.
