You have to see this!!

I am pretty sure those of you who have taken apart a 911 motor have not seen this before...if you have...please take a moment to post who did it if you know...

...the lead in...

A fellow Pelican member came over today to get a crank for a 2.7 motor he is rebuilding...his is currently U1 and he was hoping to get a STD/STD Unit...well...not today.

First clue something was wrong was while pulling the cylinders...hmmm...anybody ever run across cylinders that were RTV'd in place? By that I mean...RTV run along the unfinned portion of the cylinders then inserted into the case....sorry no pics of that.

The case is split and the crank is removed....we unbolt the rods from the crank and here is what was found...

Every rod was treated to this high performance (I stole this quote from cstreit) "Rod Oil Filter" treatment.

Is that the paper protection that they are packed in box with?

jstgermaine · jstgermaine's Garage

That's what I thought at first...however some of the papers have population stats on them

So to make up the wear somebody put newspaper? in there?

Jeff Alton · 12-16-2005, 02:52 PM

Let me get this straight. The clown who built this motor attempted to get better bearing clearance by "shimming" the bearings with newsprint?
Am I reading this right!! :0 I do know of a couple of guys around here who think the proper way to seal a case is with permatex aviation gasket sealer!!!!

Cheers

Funny you mention MM...I purchased the '77 this came from, sight unseen back in 2001. The PO lives in Downey. I can't say that they did the rebuild...for certain.

I drove the car for about 500 miles and then pulled the motor and started the conversion to a full on track car, purchased another 911 as a driver, and basically pushed this one into the back corner of the shop for the last 5 years (5 years in January).

You should have seen the dumbfounded looks on our faces upon discovery.

I could imagine your looks! Your chins are probably sore from having them hit the ground! Man, that is crazy. However, the guy has more imagination than I do, I just don't think I could come up with an idea like that!!

I actually tried to be angry...but this was so far out of the box, I had to laugh...(it helps that I knew the engine would need a total rebuild to ever be streetable and I have the 3.2 in the 74).

I'll snap some additional pics of the other quick fixes and post them on Monday.

Jeff Alton · 12-16-2005, 04:34 PM

Looking forward to more pics! LOL, man...........

Cheers

this is a very old days trick used in the 50s - mabe 40s just after the poured bebbet saga to make up for loose bng.....but real live shimstock was used on old slow turning stuff.........................

helidoc · 12-17-2005, 04:00 PM

This reminds me of a story that my uncle told me about one of his trips with my dad back in the depression era. They were apparently driving across the desert in sourthern California and had a real problem with rod knocking on the old car they were driving. He said that they pulled off the pan and lined the rod bearings with bacon fat to get them to where ever they were going. However, I really don't know if the story was true or not.

Lukesportsman · 12-17-2005, 06:14 PM

Maybe its a secret trick to prevent rod damage if the bearing would spin. I mean, they relieved it for oil flow, right? I would have thought a dollar bill to be more suitable even though more costly.

How many sheets of newspaper does it take to close down say .005" slop after wetting and compression? Just for future reference....I'm hoping to build a turbo engine this summer and wanted to get it right.

afterburn 549 · 12-17-2005, 06:57 PM

in the old Model T they would even put in leather.....but really there is no excuse for the above mentioned fix......what happens to paper after awhile in oil ???dissolves I think

You ppl are too young....
When we had problems with an old inline 6 flathead (Dodge)...we just took off the head and pan...disconected the bad rod...pounded a piece of wood down the bore...."softened" the head gasket by hitting with a mallet (solid copper gasket)...and re-assembled!!
The old 5 cylinder worked pretty good.
Not quite as smooth as 6...but good enough to get us home...and traded in for a newer car the next day.
And...for those keeping track...yes...banana peels in the rear end do make the gears quieter...for a day or two.
Remember to have you pre-purchase-inspection done....I might be the previous owner.
MUHAHAHAHA

I have removed a rod from a V8 and put electrical tape and a hose clamp around the journal to maintain oil pressure, but that was only to get home from a bad trip to Baja california (Mexico).
The above fix on a 911 engine is truly a sin.
Shame on you who did this, where ever you are.

afterburn 549 · 12-17-2005, 08:55 PM

like said.....works for awhile.....not in my P engine !!
