heat exchanger pipes, 1974 914 1.8 Options

[brcacti]

Hi all, I made an appt to take the car in have oil fumes inside car when pull heater knob. The porsche mechanic said probably have oil dripping on the 3-4 foot long heat exchangers and inside for years built up. He said on VWs they usually replace them are they available for 914s. If not available he said he may be able to bring them to a radiator shop and have them cleaned out. I need some guidance, opinions and suggestions on this project.

It is not uncommon for oil to pool in the heat exchangers and then when the exchangers get hot the fumes can blow into the cabin when the heater is turned on.

I am sure you can find good condition heat exchangers in the Classifieds here if your exchangers were in bad shape. Or if not bad, having them boiled out by a radiator shop seems like a good way to approach the problem. After almost 46 years, boiling them out seems very reasonable. I would also check to make sure your heater flappers are functioning properly as well as having all of the blower hoses connected in the system.

To make life easier for either you or the shop, I would start spraying the heat exchanger fasteners, all of them, with some form of penetrating oil for a good week before you take the car into the shop or attempt to remove them yourself. Spray them daily for the week and then hope they come loose easily and with no drama.

Good luck and above all have fun and enjoy your car. (IMG:style_emoticons/default/beerchug.gif)
