Oil leak at distributor.
FINALLY got my "new" engine in my Velocity...
Took it out for a test run and ended up with oil ALL over the bilge.. Looks to be coming from the distributor..... Did some investigating and found that the hole in the intake isn't centered with the distributor location in the block :( This allowed one side of the gasket to fall in the intake and not seal ! Anyone ever run in to this before ? http://i130.photobucket.com/albums/p...psezqkopeg.jpg http://i130.photobucket.com/albums/p...psdjfzfaka.jpg http://i130.photobucket.com/albums/p...psqcppkpee.jpg |
Thinking of using a shim washer and grinding the outside then siliconing it to the block centering the distributor hole then just use a regular gasket on the distributor...
https://img.accu.co.uk/products/HSHN-A2_lg.jpg Any OTHER ideas on how to stop it from leaking. ? |
How would that affect gear wear on the distributor shaft and cam? Got the oil pump shaft to consider as well.
|
I've never seen anything like that before. What engine is this?
|
It's a BBC tall deck Dart block. AFR heads and a Cutler intake....
Heads were flat milled. Intake has never been milled.. Had to use the .120" thick intake gaskets.. Everything ELSE lined up just fine.. :) |
How about intake manifold pushed back too far when bolted down i have some intakes with excess clearance for bolt holes allowing intake to shift front to rear. Maybe look at front of intake to block for setback.
|
It also looks like the angle at witch the face of the hole to the distributor is off also. maybe time for a new manifold?
|
Looks like it is rolled to the valley ......like Kensfourwinns said but more side to side. Can you see or feel if the gap is the same between the dist. base and the manifold when you get close to seated ?
You might need to drop the dist. in when resealing that manifold , gasket could let it move around as you tighten it. |
The manifold was even front to back,
AND was even side to side on the block wall.. ( I looked at this a bit as the manifold had bottomed out before sealing to the heads with the stock .060 gaskets) When I drop the distributor in without a gasket, the sealing surfaces ARE square with each other... Seems Cutler had some machining issue... ;) |
i would be checking port alignment as well,it looks like the manifold was installed to far backwards.hard to really see from the pictures.
|
Cutler isn't the only one. I've had a few like that. Not quite as bad.
|
A Nylatron washer might be easier to work with ......if you can find one 2 mm thick just use it as your gasket after you grind off one side .
That sucks on the alignment |
looks like somebody machined the dist hole deeper. check to see if dist body seats to manifold or if it is being held up by oil pump drive.

I'd LIKE to replace it with a slip collar distributor but not finding much luck finding one that will work.. Has to be marine certified. Slip collar HAS to be a ready to run.. My efi doesn't have a "mag" input Locked out timing. Re-phasable rotor. (my Thunderbolt rotor is phased just the the Crane hi6m was) |
Can you find somebody with a lathe and machine off the lip on the dist. and just add a slip collar to your distributor?

I'm not sure.. Problem I see is it's a cast aluminum distributor and not round above the flange... http://i130.photobucket.com/albums/p...psqcppkpee.jpg I DO have a "tall deck" version of a Thunderbolt, designed to be used with a tall deck block and a standard intake manifold using spacers.. It's about an inch TOO tall.. may be able to figure out a slip collar for that one... http://i.ebayimg.com/images/g/xBwAAO...~Y/s-l1600.jpg |
Just curious, did you happen to remove the throttle body and look down the runners with a light to see how things are lined up ? And do you see any wear marks on the bottom of the distributor gear where it's rubbing on the block ?

Looks like voice to text. Long gate I figured out. What is a China wall?
|
That dust hole in intake is WAY too big. It is supposed to be a loose clearance fit on distributor body. That is close to half inch bigger than dist. Dist can flop all over in there. GET A NEW INTAKE!! Somebody butchered that dist hole. I was thinking mebbe a bushing to correct suze, but they could cut it out off-center...
|
ok, spoke too soon. then went downstairs and checked a block, intake and dist. the machined sleeve lower on dist centers it in the block. the inside bore on hole in the intake has plenty of clearance. it has no bearing on location or angle of distributor.

I actually found a washer in my "magic toolbox" that fit without ANY grinding that was about 0.5 mm thick.. :)
It's a tall deck intake designed to use a standard distributor.. If anything, my distributor is a bit on the short side. I have about 1/4" oil pump engagement . The cam gear pattern is just a little below center on the distributor gear... I'd LIKE to replace it with a slip collar distributor but not finding much luck finding one that will work..

It can be done , I know someone that just did this last week. Slip collar was added to a short deck merc dist. |
Backyard a**hole method. Get a,4.5 right angle grinder and coarse sandpaper pad. Stick dist in dist hole of spare block and rotate dist body while sanding Dia down to match area below clamp flange. That slip collar is only a Lil thicker than the flange. There will be plenty of meat to clamp it to. And we have already ascertained if collar is a couple thousand to one side or the other it won't affect alignment...

Intake fits FINE other than the distributor hole.. Ports line up. front and rear wall is fine..
The distributor gear doesn't rub anywhere. The cam gear pattern is from the center to the bottom 1/4 of the distributor gear. I siliconed a washer to the intake like I mentioned earlier.. took it out today.. no more oil leak.. :) |
Glad to hear it, enjoy !
