I put the engine back in and cranked it over following the rebuild. I found significant oil leaking/draining from behind the impeller housing. I ended up pulling the enginen out and looked at the source, thinking I did not get the oil in and out barbed fittings tight. To my suprise, I found a fitting hole which I cannot remember what its purpose is. I believe this to be the source of oil loss.
This is a modified 2.0L. We run an external oil cooler in series with our stock oil cooler. Denny removed the stock oil filter mount and capped it off with a plate. He plumbed the case for _8 fittings for oil in and out to the external oil cooler and remote mounted oil filter. Attached image(s)

You'll never develop oil pressure that way, lol.
Put a SS plug in it, looks like 3/8" NPT. |

What is it doing there? Looks like its the boss is cast into the case.
While we are talking about leaking oil, what should I use on the NPT nipples, joint compound or is teflon tape OK? dr |

Someone drilled that galley and tapped it. Just plug it off, like Chris says.
The oil filter blockoff looks inverted or put on backward, it should look like synthesis' does. Synthesis, don't get teflon tape around those use permatex 56521 teflon paste. put nothing on the areas where the AN fittings meet another AN fitting, they are designed to seal without a sealant. |

I'm using a remote oil cooler adapter that I really don't like. It sends the oil lines straight up from the old cooler location and they interfere with rotating the distributor to time the engine.
I see the solutions posted here and I'm intrigued. A simple blockoff plate for the oil filter is nice, can I do the same for the stock cooler? Also, it looks like you gentlemen have NPT fittings in the front of the block. Did you tap these yourself or are they already there? I didn't look real close at that area when the engine was out. |

Watch those long extensions on your oil ports. All those connectors and adapters in series are like a long lever that will tear your motor up with extreme motor vibration. Since I couldnt fit any AN fittings past the pump plate, I had the local hydraulic shop make these short hoses that go directly to the case port return and the pump plate outlet.
I will attach the AN lines to the ends of the short hoses, makes it easier to reach once the motor is in the car too. The return port was tapped into the case and the outlet is part of the billet pump plate on the front of the motor. dr Attached image(s)

Cool setup.
I have flex lines going to the remote cooler adapter, so the "long extention" problem should bother my setup, but they're in the way of the distributor. dr, are you on the track yet? I ran a race (test session for me) at Waterford Hills this weekend. Learned a lot. |
