I in the recient past bolted a set of David Godfrey's ported intakes on my car along with a few other things.
The upper intake was the short style so I used a T-C throttle body to gain the needed clearance over my stock cam cover.
Today while chasing an oil leak I installed a nonported tall upper and the stock throttle body.
Performance is way down compaired to before.
What do you think? Intake make that much difference?

Now while you are here I finally found the oil leak I have been hunting for.I think.
It apears to be the dipstick tube,the tube is tight in the engine,but it does look as tho that is where the oil is coming from.
Is there an oring seal on the tube?Is the tube pressed into the block?
I plain to fix this over the holidays and would like to do what it takes to do it right. Input please.
Thanks,
Don

Mike,
That is how I thought it fit,I tryed to turn it or pull it up by hand and it did not move any at all.
Is it possible that it is the oil cooler leaking instead of the dipstick tube,and the oil blowing back wetting it down?
Man it is hard to see in there,I first thought it was the oil feed line to the turbo,changed that,still have leak.
The side of the block in that area is wet and I have what looks like oil spray on the hoses that go to the oil cooler.
I have replaced the fitting that the oil pressure sending unit screws into,the sending unit it's self and the turbo oil feed line.I have checked as best as I can to make sure it is not coming through the head gasket,I don't think that is the case because it is dry in that area.

Here's what I'd do to isolate the leak:

!. Clean up the entire area of oil.

2. Tear up some long strips of clean cloth from an old shirt, socks, etc.

3. Wrap the cloth and tie it around the base of the dipstick, the oil pressure sender fitting, the oil cooler, and any other suspect areas.

4. Drive the car until one of the strips becomes oil saturated and gives away the location of the leak.

NEVER try this on the turbo side of the engine.

Another candidate for the leak that you didn't mention, Don, is the large O ring on the distributor shaft where it plugs into the block. You might tear off a strip of Pat's Best Shirt and wrap it around there also to check for a leak!
