LT1 Distributor Question
Does the LT1 block have a location for a traditional distributor in the back? The reason I am asking is that I am tracking down a pesky oil leak coming from the back of the engine. A friend of mine told me he has the same problem on a different GM engine and it was coming from a plug in the block where a distributor would go but the car had digital ignition from the factory just wondering if the LT1's are the same.
Thanks

Tony, It has a place for it but it's not drilled out. It's not going to leak. Many times the RTV seal does start to leak back there. You could also check around you oil pressure sending unit. That's most of the leaks.
If you do take it off to redo the seal make sure that you clean the mating surfaces with carb cleaner or some strong solvent. Take a little of the RTV and put some on your finger. Rub it into the Block and the intake mating surfaces. It will act as a primer of sorts. Before it dries completely assemble the intake.
It's not a long or involved job. Probably take less than a six-pack to pull it off.

LT motors are notorious for the intake seal leaking in back. Like 1963SS said reseal the intake. It's a easy job especially since there is no coolant in the intake. Just need the side gaskets and RTV for valley seal.

As stated, this is a straightforward parts-on-and-off project. If you are a little tentative about it, take a bunch of pictures first, and label the wires and hoses as you remove them. There may be pics, etc. to be found in the "search" on this forum. Best bet is to get your hands on the FSM, you'll find it laid out step by step there. Some guys, me included, put small dimples on the mating surface of the manifold (just where the RTV goes, not the gaskets) with a punch.

You don't even need an FSM for this. Get a Haynes manual and do the step by step procedures on removal and installation of the intake manifold. The seal on the front and back of the manifold are RTV style seal-in-a-tube. Opt for the better stuff. Don't go cheap on it. You'll regret the cheap stuff later.

It's true, the Haynes is more than adequate for this job. I didn't suggest it because, in the long run, my advice would be to take the money you would spend on the Haynes and put it toward the FSM. Sooner or later, you'll be glad to have it.
