What distributor are you running in your 907?
|
Mine is a lucas 23 or d25. it is leaking bad and after talking to steve at sjs he said its either the distributor needs to be rebuilt or the engine breather is blocked as it is not as this is a fresh rebuilt engine with 300 miles on it now. its been coming out the sides. According to him this is NOT the distributor with the internal seal as i went to rdr one from him. If you were me woudl you opt to have it rebuilt or upgrade to another one? The leak is pretty bad and worries me, iw ant to address it now that myc ar is running. its currently getting paint fixes done but will have it back next week. Any inputs would be much appreciated!

This is a very nice unit with a great app for your phone. Also serves as anti-theft device. Very easy install and works as advertised.

JSPS? Jensen healy parts . Phone No. 1 - 949 - 395 - 6818
I have a 1977 Lotus Esprit S1 ,
Got a 25 d distributor from them.? My car Runs AMAZING.
You talk about a leak.
Where exactly, is the leak ?
You may just need an O ring at the end of distributor shaft.
NOTE. If you use the ,

the vacuum advance will hit the oil filter, if you don't use a Lotus oil filter.
As it's shorter and stubbier.
Just a tip, guys with Esprit S1 and S2 .?
Oil filter by,

You have no vacuum advance as in that, it's not hooked up. Or no vacuum advance diaphragm on the distributor.? Just wondering.?

If you are going to buy a Lucas... or Lucas-like distributor, then I recommend the 43/45D4, not the 23/25D4. The 23/25 is much smaller in diameter, and the distributor cap is more "spherical" than squared off in cross-section. Net effect is that the spark plug wire terminals are much closer together on the 23/25, and further apart on the 43/45. That means that the 23/25 is limited to lower coil output voltages. If you wish to use a FlameThrower or other "hot" coil, you can't do that with a 23/25D4. Period! Well, not successfully. The 43/45 is a drop-in fit where a 23/24 used to be. Easy. There's a rubber O-ring around the outside of the distributor's shank, just below the distributor's "head". It seals just inside the oil pump housing's bore where the distributor slips in. That O-ring can leak, but that's not usually the big problem. If it does leak, then it leaks around the distributor's shank, where it disappears into the oil pump housing. The Lotus 900-Series engines were the only ones that ever mounted the Lucas Distributors horizontally. A small lip seal was installed inside the housing (not originally, but eventually), where the shank's lengthwise bore broke into the "head"/housing. If the lip seal leaks, the oil will leak into the "head"/housing, and escape from the distributor at the joint between the "cap" and the distributor's housing. If that's where you're seeing oil, then the lip seal is either worn out, or was not installed during a prior repair or rebuild. The "horizontal" Lucas distributor "NEEDS" the lip seal!! Period.

P., A 3.0 ohm or higher "primary" resistance is "mild", and very to the stock resistance. That coil should be very compatible with the stock distributor... even the 23/25D4. Shop around, and you'll find "HOT" coils (including other Flamethrower models) with primary resistance down to 1.5 ohms, and lower. Those are the ones that draw lots of current, and put out a "HOT" enough spark to arc between the spark plug wire TERMINALS on the distributor cap.

If it's a Lucas distributor, there was no change made in order to fit the lip seal. Look down into the head of the distributor to where the shaft disappears out of the distributor's "head", into the "shank". IF you see a bushing flush with the surrounding "floor", then he's correct... it's not a Lucas distributor that originally had a lip seal. However, NO MODIFICATIONS were made to the distributors in order to install the seal. The seal has the same outside diameter as the bushing (bearing). All they did is push the bushing down about 5mm further in order to make room for the seal, then push the seal in behind the bushing. Upgrading an early Lucas distributor (ie, no seal) to include a seal is not rocket science. Simply push the bushing down to make room, then push the lip seal in behind it. IF he's telling you the distributor will require an overall rebuild just to install the lip seal, then he is either unaware, or he's BS'ing you. There are other, modern distributors that are designed to be direct replacements for vintage Lucas distributors. However, I'm aware of none that include the lip seal that the horizontal Lotus application requires. For instance, the Pertronix electronic distributor does not include a seal, and they steadfastly refuse to install one. I won't use one in a Lotus 900-Series engine, whether it's in a Lotus, Jensen-Healey, or Sunbeam Alpine Lotus rally car. I won't use the Pertronix (or any other brand with no lip seal) in any of the above cars. You shouldn't either.

P., Jensen-Healey used the 907 1972-1976... four years. from 1972–1976, they built 10,503 J-H. However, Lotus continued to use the 907, 910, 912LC, 912HC, and 920 thru 2001 (the 920 was the last one produced), not to mention the 911 in the Sunbeam-Alpine-Lotus (Lotus built the cars for Sunbeam-Alpine). Over-all, about 25 years longer than J-H (ie, 25 years after Jensen closed their doors). It might be reasonable to presume that Lotus has more experience with "their" engine and it's sub-systems than Jensen did. Tim 11/07/2024 11:30 PM CST P. <pasqualeelauqsap850@...> wrote:

Yes all you said makes sense. However if you are trying to get the Esprit S1 running like a Top.? I used the 25 d 4 and couldn't be happier.. along with the 10 mm plug wires.? KGK BP6ES spark plugs. or equivalent.? You have to research that. As long as they are non resistor plugs.? My Esprit S1.? Pulls very strong, through every gear.? The thing to consider, is that ,I have WEBER'S CARBORATORS 40 DCOE-18. with 4.25 inch long stacks.?

No advance on the distributor.? Mines purely mechanical. Here's some photos I took before sending the car in for paint touch up.

As it's shorter and stubbier. Just a tip, guys with Esprit S1 and S2 . Oil filter by, MANN W 917 Wich is the same as the LOTUS. MANN W 917 is used on Volvo P 80 cars , eg.

The seal in question is a lip seal inside the distributor that was added to the Lucas distributor either by or for Lotus. Unlike the oring that is easily replaced anytime the distributor is removed, these seals are rarely replaced because you have to completely disassemble the distributor to get to it. ? What’s more, many distributor shops fluent in the Lucas distributor still don’t know about the Lotus seal because in terms of Lucas distributors the seal is a real rarity. If it’s there and original, it’s no doubt crunchy. If you don't know it’s been replaced then replacing it would be a good idea. If you get in there and find its not there then adding it would be a good idea. ?On the 43/45 series the housing was not modified for the seal, they simply pushed the top sleeve bearing down to make room for a seal and found a seal that fit the existing shaft and the existing housing bore, didnt even have to modify the sleeve bearing. ?You have to remove the distributor shaft from the housing to replace it but it’s not difficult. ?I don’t know off hand if the 23/25 had the housing modified for the seal or not but getting it modified should not be difficult if required. I have modified one of the Chinese Lucas replacement distributors for a seal and it was pretty simple to cut the distributor housing on a lathe once everything was removed to make a pocket for the seal to fit.
All of that said, your immediate gusher could be from your new engine still breaking in and having a bit extra crank case pressure.?
I have a 123 distributor in a Turbo Esprit and it has so far worked great but it does not have a shaft seal either so if your pushing oil into the housing of your current distributor at the rate you are, then the standard 123 may not solve that problem. And these are known to have electronic issues if the board gets too oil soaked. 123 do have an oil screw solution for the distributor shaft that they do on I think some BMW that is prone to leaking through the shaft as well and while that doesn't make a seal it might solve the problem. If you try the 123 then I recommend asking about that. It seems to be a really good distributor and is easy to tune. ?I bought the Bluetooth version because the Turbo Esprit timing is a bit weird due to the turbo but I suspect that one of the standard curves they offer would work well on the basic 907.?

Hope you all don't mind me jumping in, attached are some pics of
the internal seal.?
I did this repair a while back. The closest to the original seal
I could get had the same in/os dims but the depth did need
reducing a small amount on emery paper to sit flush.
Always seemed odd to me that Lucas didn't give any extra stamping
on the outside of the casing indicating the internal seal. This
problem often occurs when swapping out.?
Personally I'd try to track down the correct dizzy for the car. I
try to add to this list each time a see a new number somewhere:

Mind???? Absolutely not, jump in. No stamping and no one outside of the Lotus and Jensen Healey community seems to know its there. Thanks for the pictures, that does verify that the housing is modified.?
