You know if the mounting of the pump at the front was not sealed, oil could leak into the valley under the pump.
If you don't mind going through the process of getting to the pump twice you might set everything right and see how it runs.
Just a thought

That thought did cross my mind but I suspect its more than just a leak at the front of the pump. The sides of the pump are covered in oil as well. Getting at the pump twice was something that I was hoping to avoid.

Oh come on it's so much fun, and it's faster the second time
There is a banjo bolt on the right side that is connected to the engine oil. Also if the altitude sensor is not sealed oil will leak. The same goes for the oil filler pipe.
As a practical matter: if you know how it runs before a rebuild you have a base line to evaluate the rebuild.

I think we have a different definition of fun!

I do agree taking it apart the second time would definitely be easier. It took weeks to get the frozen injection lines off the pump.

I'm still leaning towards there being a more significant leak on the pump than what you've described. Not sure if this attached picture is adequately shows the oil. You can see a fair bit on the side of the pump and there's definitely more underneath it.

Make sure it's 60 deg after ignition TDC of the # 1 cyl. Check your camshaft marks.

It is very unlikely that oil grime on the sides of the pump is from the pump itself. These pumps leak oil internally, but there is not a source of external oil leak other than those already mentioned, and none of those require to removal of the pump.

When you reinstall the pump, it is important that you understand that it is securely held at the front by those four bolts. They must be done up securely before the two side brackets are tightened. This ensures the proper alignment of the pump drive. There are two versions of the side support brackets. The early version uses spacer washers which need to be installed after the pump is secure at the front. The second version uses a slotted vertical bracket. Either way, do not pull the pump down at the rear when doing up the side brackets.

Art, you've got me reconsidering pulling the pump. I will check the oil feed on the side of the pump and the altitude sensor as mentioned. Does the altitude sensor just need to be tightened with a wrench?

I've read through some previous threads in this board and people reference a workshop manual. Is this still available? Last I spoke with the classic center they said it wasn't.

Inside the intake manifold there was a bit of an oil film. However looking down in to the cylinder head it didn't appear there was any oil in there. I've heard it's normal for there to be a little bit of oil inside the intake manifold but no idea if that's true.

I'll run out to the garage and grab a couple more pictures of the pump.

Gerald looks like that pump spent some time in Vancouver? Company called Fred Holmes Fuel Injection, now based in Richmond BC.

Daniel, you're correct it does have a sticker on it that it was services there. Would you have any idea if that's a reputable shop for working on these pumps?

The manuals occasionally come up on eBay.
Renewing the subframe mounts and the engine mounts will help with working on the fuel filter and other components and replacing hoses as well improve the handling of the car.

Hey Gerald. No idea unfortunately. I checked out their website. Looks like they mostly do Marine pumps and heavy duty diesel pumps and such. Can't hurt to give them a call.

How difficult are these jobs? I haven't looked in to this at all. I actually don't see myself getting the car on the road this year.

I had noticed the same thing when I visited their website. I was mostly curious if they had a good reputation. It looks like I will follow Arts advice and leave the pump for now. I'll give it a good cleaning and then see I can trace any possible leaks.

Thanks Martin, I will check it out.

I'm getting closer to re-assembly as I received a parts shipment from the classic center today. I've got the hoses, belts, filters, fuel lines, oil lines, CSV o-rings sorted out. Is there anything else worthwhile to examine while I have access to the front of the engine with the radiator and AC condenser removed? Leave the water pump in place? Remove the alternator and have it tested?
