I'd drop #6 off the list and just get the right parts and put'er back together. Eric, These are my thoughts on that, because I have so many leaks in my heat exchangers even with the heat control boxes closed I am loosing a lot of air out of the leaks that could be used to flow over my oil cooler. The flaps that are missing on the bottom of the shroud would be open all of the time due to the leaks in the heat exchangers so I blocked off the air to see if it helps with air flow to the oil cooler. If this fixes my oil heating problem I will replace my heat exchangers with a good set from an older style (I have the 76 setup). |

I'd drop #6 off the list and just get the right parts and put'er back together. (IMG:style_emoticons/default/agree.gif) Aside from being aircooled, they are oil cooled and fuel cooled. So, the oil cooler needs to do its job with proper air flow. You can position the flap to always be putting the most air into that cooler...you like in the desert. For fuel, these cars are designed to run rich, it helps keep the motor cool. Timing and a slightly rich mixture, along with proper air flow will hopefully solve this. Acorns and nests are just all part of the pleasure of an aircooled car. rich Reminds me of the old Lotus turbo advertisements of "charge cooling". (Paul Newman era). I read that they may have had charge cooling but they were still hot as a pistol. I agree, I found that fueling and timing are really important. We get maple leaves and little boxwood pellets but not so many acorns. Fortunately the ground squirrel prefers my wife's mini van hood liner. |

Gunny, just for my curiosity, are the two air deflectors under the floor, just at the rear floor edge in front of the engine still there?

Acorns and nests are just all part of the pleasure of an aircooled car. rich I was thinking the same way, That is why I checked the air fuel mixture by adding the wideband sensor. I was a little lean but know i'm running 12.5 to 1 at steady speed. I have checked the air flow around the motor and only found a small amount of debris on the top of the driverside cylinders. I have been leaving my flaps in the hot position all of the time, I'm in Alabama. I think I'm not getting enough air to the oil cooler. I have all gromets in the tins and all tins are in place. I'm hoping that blocking the air to the heat exchangers will force more air to the oil cooler. I will find out when I finish cleaning everthing and put the motor back in the car later this week. |

No Gunny, I dont mean the heater control boxes but the plastic flaps, one on each side, they really help cooling when cruising. They came with the -73 (2.0 at least) and all cars after that should have them. Pls see this thread for explanation: Deflectors /lars S |

I had a similar problem with my 75 1.8L. It has an auxiliary oil cooler with a fan mounted on the backside controlled by a thermostat set to come on at +180F. I was experiencing oil temps of 230-240F consistently. I solved the problem with a small air scoop cut into the passenger side rocker panel just ahead of the rear wheel. It has a 2 1/2" flex hose that is routes fresh air directly onto the auxiliary oil cooler. The oil cooler was modified with flared sides to help direct the air. Now my oil temps are at 210F. Oil pressure is 40 psi at 3400 RPM (at 70 mph). Chris Foley at Tangerine Racing suggested this set-up and it worked well for me. Pictures we need pictures! Thanks |

Front mounted oil cooler should have been an OEM feature. KT That's what I'm thinking, I wouldn't have to do one.(IMG:style_emoticons/default/smile.gif) |
