Re: [VintageLambo] Re: burst oil cooler pipe

Jack Riddell

Body of Message

Hi Clive, When I had my most recent "experience" with a ruptured oil cooler, it was the result of poor planning by our local utility, San Diego Gas and Electric. They had dug a large opening in a street near my home to gain access to an in-ground electrical box. They then capped the hole with a steel plate that was about five feet square by one inch thick Normally, when they used the steel plate covers, they build an asphalt ramp around the edges to avoid the abrupt lip of the plate, but in this case, they did not. The plate was located only inches from a "dip" in the street caused by a small drainage culvert. Anyhow, the combination of the dip and the 1" steel lip was catastophic to my poor oil cooler.I limped about 30 feet to the side of the road and killed the engine. I checked the level on the oil dipstick to assess the amount of oil loss and found that I could still measure oil but well down the stick. I decided to chance it and drove the car the remaining one block to my home. There was no damage to the engine as a result. I think like Fred pointed out, these engines are pretty tough. I wouldn"t drive more than a city block in these conditions, however. Better to get the tow truck. By the way - the utility company paid for the replacement oil cooler, although it took some good luck for that to happen. Seems they wanted to stiff me initially until I found a pair of witnesses who saw the workmen the following day, removing the plate and filling the offending hole and bragging about how there would not be any evidence of a damaging plate to complain about. When I confronted the utility representative with the witnesses, she immediately changed her tune and offered to pay the costs. Without the witnesses, I would have been screwed. Lesson learned - I now carry a disposable camera in my cars just in case I have any future problems as a means of capturing visual evidence. I highly recommend them for anybody.

God only knows the force the oil must have come out at as the hole is tiny, the chaffed area similarly small with a few loose threads only. I guess once the protective skin is disturbed only the slightest nudge will burst the pipe. The really surprising thing is the hot oil did not ignite when it sprayed the manifolds - they were covered! I"m hoping Fred"s theory is right and the engine is OK - that"s my real worry of course....
